Terms and Conditions

1. Introduction

These Terms and Conditions (the "Terms and Conditions" or "Terms") are a contract between you, the user, and MB "Bit by bit developers", a limited liability company with its place of business at Volungės g. 5-1, Vilnius LT-10315, Lithuania (the "Company", "we", "us", or "our").

The Company operates the bitbybit.dev website and all its subdomains (the "Platform"), including but not limited to:

• bitbybit.dev - the main website offering visual programming editors, project galleries, 3D model configurators, educational content, and community features;
• api.bitbybit.dev - the application programming interface (API) gateway providing server-side computational services including, but not limited to, 3D geometry processing, file conversion, parametric model generation, and other related services (the "API Services");
• studio.bitbybit.dev - the customer dashboard for managing API keys, monitoring usage, running conversions, and managing subscriptions (the "Studio");
• any other subdomains, tools, or services operated by the Company.

The Platform provides services allowing users to create, share, and remix projects containing scripts and various assets, access API Services for programmatic and server-side computational processing, manage API keys and subscriptions through the Studio, upload and convert files, and execute computational tasks on managed cloud infrastructure (collectively the "Service" or "Services").

By using the Platform and any of the Services you are agreeing to be bound by these Terms and Conditions. If you do not agree with these Terms and Conditions or any part of this contract you may not use the Platform, Services, or products that we provide.

Serious or repeated violations of these Terms and Conditions may result in suspension or termination of your Account, including the removal of associated data. The Company will exercise this right proportionally, taking into account the nature and severity of the violation.

By agreeing to these Terms and Conditions you also agree to use the Platform, Services, and products at your own risk. The Company reserves the right to refuse service, products, or access to the Platform to anyone at any time for any lawful reason.

3. Account

You must agree to these Terms and Conditions and provide the Company with all required information during registration in order to create an Account. You are responsible for keeping your Account and password safe. The Company cannot be held liable for any damages arising from your inability to fulfil this obligation. You must also update the information about yourself when it changes.

You are responsible for all Content that you post on the Platform. You are responsible for any activity coming from your Account, including activity arising from situations when others use your Account.

All the information that comes from your Account is subject to our Privacy Policy. One Account must be maintained by one person or legal entity. Accounts may not be created and operated by automated methods. "Bots" are not allowed.

4. Our License to You

The Company grants you individual private access to the Platform and provides a non-exclusive and non-transferable right to use the Platform for your internal purposes. You may not transfer the right to use the Platform to third parties. You may not interpret these Terms and Conditions as allowing such transfer to happen.

You may not build products that look and feel like the Platform. All rights to the Platform are held by the Company and its licensors. You may not modify or create derivative works based on the Platform. It is forbidden to reverse-engineer parts of the code that are not open-sourced to make competing products that copy features of the Platform. You acknowledge that all the rights, interest, and title to the Platform, including all intellectual property rights, are owned by the Company.

API Integration Rights: Notwithstanding the above, if you hold an active API Key subscription, you are granted a limited, non-exclusive, non-transferable right to integrate the API Services into your own applications, products, and services for commercial or internal use, subject to the usage limits and conditions of your subscription plan. This right does not extend to reselling, sublicensing, or white-labeling the API Services themselves as a standalone offering. You may not offer the API Services to third parties as a separately marketed product or service without a separate written agreement with the Company.

Bitbybit Runner. The Bitbybit Runner is distributed under the Bitbybit Runner License, a separate license included with the Runner files. The Runner may be used freely, including for commercial purposes, without requiring a Platform account. The Bitbybit Runner License governs all use of the Runner, whether or not you hold a Platform account. If you hold a Platform account, these Terms and Conditions apply to your use of the Platform and Services in addition to the Runner License.

Runner and Open-Source Components. The Runner incorporates Open-Source Components governed by their respective open-source licenses (detailed in the NOTICE file distributed with the Runner). Nothing in these Terms restricts your rights under those open-source licenses. However, the Runner also contains proprietary components authored by the Company. You may not reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code or underlying algorithms of the proprietary components. The build scripts and tooling used to compile the Runner are proprietary and are not part of any license grant. You may exercise your rights under open-source licenses, including replacing dynamically-linked components such as the OCCT Web Worker (licensed under LGPL-2.1). See our documentation for technical details.

CDN Availability. CDN Assets hosted on the Bitbybit CDN are provided for convenience. The Company makes no guarantees regarding the availability, uptime, performance, or continued hosting of CDN Assets. Versions may be deprecated or removed at any time without notice. For production deployments, the Company recommends self-hosting CDN Assets on your own infrastructure. The Company shall not be liable for any disruption, downtime, or unavailability of the Bitbybit CDN.

Self-Hosting. You may download CDN Assets from the Company's asset releases and host them on your own infrastructure for use in your own applications, provided you do not modify the Runner files or their proprietary components. Self-hosted assets are your responsibility: the Company provides no support, warranty, or liability for assets hosted on third-party infrastructure. You must maintain the original directory structure expected by the Runner and ensure all assets are publicly accessible.

Ownership and Brand. You are the owner of Content that you create or upload to the Platform. The Company is the owner of the complete Platform. All intellectual property rights and copyright to the Platform belong to the Company and its licensors. The Platform and Services are protected by copyright and other laws of Lithuania, the European Union, and foreign countries. Nothing in these Terms grants you permission to use the "Bit by bit developers" logo, name, domain names, or other distinctive brand features. You may not reproduce, copy, or transfer any part of the Platform in whole or in part.

5. Community Standards

You may not use any harsh language towards other community members. No swearing, bullying, harassment, or discrimination are allowed on any part of the Platform. You may not post offensive or otherwise disturbing Content that would hurt others.

If you publish projects to others you are held responsible for all the Content in that project, including but not limited to titles, descriptions, assets, and models produced. If you do not respect these terms we have the right to remove your projects and block you from accessing the Platform. In no such event will we be held liable for the loss of data or other damages that this may cause you.

6. Harmful Content

You may only upload Content to the Platform that you own or have the right to use and expose through the Platform under the license terms described above. You agree that you have not and will not create, upload, or otherwise contribute Content which does the following:

• Violates the trademark or copyright of another party.
• Reveals trade secrets in any form, unless you own them or have the owner's permission to disclose them.
• Infringes on intellectual property rights of others.
• Infringes on privacy or publicity rights of others.
• Is harassing, hateful, offensive, disturbing, abusive, pornographic, or threatening.
• Violates any law or any right of a third party.
• Is incorrect, deceptive, or otherwise misleading and you are aware of that.
• Impersonates others.
• Reveals personally identifiable information of others without their express permission and authorization.
• Contains or links to trojan horses, worms, time bombs, viruses, or programmed routines, engines, or software that can damage computer systems, leak information, detrimentally interfere, intercept, expose, and otherwise corrupt data or systems.

You agree that the Company has the right to remove any Content that has any of the abovementioned characteristics, delete your Account at any time, or otherwise stop it from being used. We also reserve the right to take legal action available under equity of law.

7. Your Responsibilities

You agree that all the information you provide us with during registration and when using the Platform and Services is correct, accurate, current, true, and complete. You also agree to maintain and update such information when it changes.

The Platform and all the Services we provide are only available to people who can form legally binding contracts under the law that applies to these Terms and Conditions. Our Platform and Services may not be used by unsupervised minors — persons younger than 18 years old may not create their own accounts. If you are a parent or legal guardian and you create an account for a minor — a person younger than 18 years old but older than 13 years old — it is your responsibility to determine if the Platform and Services are appropriate for such minor. We do not seek or knowingly collect any personal information about children under 13 years of age. If we become aware that we have unknowingly collected personal information from a child under the age of 13, we will make commercially reasonable efforts to delete such information from our database.

You agree to notify the Company immediately if you recognize any kind of breach in security on the Platform. This includes but is not limited to unauthorized access to the site, use of a password or account, harmful scripts, data, files, or programs. You also agree to stop all use of the Content that might be related to such suspected security breach. If your Account is hacked or otherwise compromised you must inform us immediately at info@bitbybit.dev.

You are responsible for keeping your own devices, software, and internet connections up to date and secure.

8. Strictly Forbidden

The following activities are strictly forbidden:

• Hacking, attacking, or attempting to compromise the Platform, its infrastructure, or any third party's systems.
• Phishing, impersonating other users, or manipulating cookies, headers, tokens, API Keys, or other credentials to gain unauthorized access or exceed plan quotas.
• Breaching intellectual property rights or other rights of others.
• Using the Services for purposes other than CAD modelling, engineering, architecture, manufacturing, 3D printing, data visualization, creative coding, gaming, and related technical or creative disciplines.
• Uploading Asset files not actively used in your Projects.
• Spamming, unauthorized advertising, flooding servers with automated content, or distributing conspiracy theories, pyramid schemes, or other harmful material.
• Scraping, crawling, or using automated means to collect data from the Platform.
• Collecting personal information of others, or implying that we endorse you or your Content.
• Using the Platform for any illegal activity, violating your local laws, or engaging in any form of discrimination, harassment, or bullying.
• Circumventing, bypassing, or attempting to exceed API rate limits, compute quotas, file size limits, or spending caps through any technical means.
• Using API Keys in a manner that degrades service quality for other users, including excessive concurrent requests, abnormally large payloads, or intentional resource exhaustion.
• Reverse-engineering the API Services to extract proprietary algorithms or internal system information.
• Reselling, sublicensing, or providing API access to third parties as a standalone service without a separate written agreement.
• Submitting files or parameters designed to exploit vulnerabilities, cause excessive resource consumption, or trigger injection attacks.
• Attempting to access, modify, or extract Tenant Configurations, data, or workloads belonging to other clients on the Shared Infrastructure.
• Using Tenant Configurations or Custom Development deliverables to reverse-engineer the Platform or any proprietary component thereof.

9. Reserved Rights

• We have the right at any time to remove or refuse to host any Content on our Platform.
• We have the right to remove any users and all their data, terminate their accounts, and reclaim usernames.
• We have the right to preserve, access, and read any part of the Content that you create or upload on our Platform, and to disclose any part of it that we think is necessary in these situations:
  • When we try to protect our users, ourselves, the Company, or others.
  • When the government requests such information.
  • When trying to satisfy any legal process, regulation, or law.
  • When we need to enforce these Terms and Conditions and we think you violate them.
  • When we get reports from other users or third parties which think you are violating these Terms and Conditions.
  • When we try to prevent security incidents, data leaks, or other cases of fraud.
  • When we investigate and address user support requests.

10. Your Feedback

Whenever and wherever you provide us with suggestions, ideas to improve the Platform, report bugs, problems with the service, or any other feedback related to the Platform, you agree that we can use your feedback without compensation. By providing such feedback you grant us a royalty-free worldwide non-exclusive license to use such feedback in any way we see fit.

11. Your License to Us

When you publish your projects, you grant the Company and other users a worldwide, royalty-free, non-exclusive, irrevocable license to use, display, distribute, and remix all of the Content therein, under the following fixed license terms:

• Source code (scripts, code, and programmatic content) is licensed under the MIT License.
• Creative output (3D models, renders, images, and other non-code artifacts generated by or included in your project) is licensed under CC BY 4.0.

These licenses are applied automatically when you make a project public or accessible to community members. There is no option to select a different license. If you do not wish to share your work under these terms, keep your project private.

These licenses are irrevocable for copies already made. Once your Content has been accessed by other users under the licenses above, those users retain a permanent right to use the Content under the license that was in effect at the time of access. Making a project private or deleting it stops the Platform from distributing your Content, but copies already obtained by other users remain validly licensed. Deletion removes hosting — it does not revoke the license grant.

While our "Private" project status ensures your project is only visible to you on the Platform, we cannot be held liable if others gain access to your private project by your own mistake. Your private projects are your responsibility to protect. If you want complete security, consider saving scripts to your local machine and protecting them yourself.

API Data is not published Content. Files, data, and content submitted to the API Services for processing (API Data) are not considered published Content and are not subject to any public license grant. You retain all intellectual property rights to your API Data. You grant the Company a limited, non-exclusive license to process, store, and transmit your API Data solely for the purpose of providing the API Services to you. This license terminates when the API Data is deleted from our systems.

12. Use of Your Published Content

When you make your projects public or accessible to community members, other users and the Company and its licensors gain the right to use, distribute, and publish all of your Content in that project on other services and media, subject to the applicable license (MIT for code, CC BY 4.0 for creative output) and these Terms and Conditions.

You agree that you will not be paid or otherwise compensated for such Content and that others can copy, remix, post, submit, transmit, and use your work freely under the license terms. The Company retains the right to use your public work for promotional purposes including commercial advertisements of the Platform.

If you delete such projects or make them private, no third party - including users of the Platform and the Company itself - is required to delete or make unavailable any copies of the Content that were already made, posted, published, or embedded in other people's Content while the project was public.

The Company retains the right to change and adapt your published Content in order to adapt it to requirements or limitations of other platforms, media, or services (for example, resizing an image or converting a format for promotional use).

13. You Are Responsible for Your Own Content

You agree that by using the Platform you are fully responsible for all the Content you create and share. If derivative Content of other users or third parties infringes on the rights of other people or businesses due to your original Content being incompatible with these Terms and Conditions, you are also held responsible for damages. You also agree and understand that others can republish your publicly accessible work or use it in ways which may expose you to be liable for possible damages. If you do not have the rights to the Content you make publicly available on the Platform, you are held responsible for all the consequences related to that.

14. Asset Download URL Links

Platform Assets: To make sharing of Assets easy we generate Asset download URL links containing tokens that are hard to guess, but can be shared by users and have public read access. People gaining access to these links can download your Assets. This also applies to Assets in private projects. If you do not share these links the chance of leaking Asset files is reduced to the minimum, but we do not guarantee this will not happen.

As a rule of thumb you should not upload sensitive information in the form of Assets to our servers that you must keep totally private. If you did upload an Asset file and you think that the download URL link to that Asset file was exposed, compromised, or guessed by third parties, you can remove the Asset and upload a new one. This way old links will be removed and a new random token for the file issued. In no event can we be held liable for the loss of sensitive information via Asset files.

API Files: Files uploaded to or generated by the API Services are stored in separate cloud infrastructure and accessed via time-limited presigned URLs. These URLs expire after a limited period and are not permanently accessible. You are responsible for downloading results within the retention window and for securing any URLs or results returned by the API Services during their validity period.

15. Rules for Assets and API Files

Platform Assets: You may only upload Asset files that obey all of the Content limitations expressed in these Terms and Conditions. Your Assets may not infringe on any third-party rights. Your Asset files must be related to the things that you can do on the Platform. As a rule of thumb, your Asset files must be actively used and referenced in the Scripts of your Project that contains the Assets. You are responsible for scanning Asset files and keeping them clean of viruses or other malicious software before you upload them. You may not use Asset file storage to store data that is not related to the projects and is not referenced in your scripts, including but not limited to movies, photos, music, or personal documents.

API Files: Files uploaded via the API Services must be related to legitimate 3D CAD, geometry processing, file conversion, or visualization purposes. File size limits are determined by your API Key subscription plan. Uploaded files and processing results are subject to automated cleanup after processing is complete, as described in the Data Processing and Retention section.

16. 3D Models

The Platform offers pre-built 3D models through the "Things" category and "3D Models" configurators. These models are licensed under Creative Commons terms that are separate from the licensing that applies to published projects. Scripts that use plan-restricted 3D models may only be shared publicly if all included models are available at the Free tier.

• Free 3D models are distributed under CC BY-NC 4.0. You can use these Assets freely for non-commercial uses with attribution. The CC BY-NC 4.0 license does not permit commercial use. However, the Company grants active Silver and Gold plan subscribers a separate, non-exclusive, non-transferable commercial license to use Free-tier 3D models with attribution, for the duration of the subscription. This commercial license is independent of and supplementary to the CC BY-NC 4.0 license.
• Silver-tier 3D models fall under CC BY 4.0 license and are available only to Silver and Gold plan subscribers. Commercial use is permitted with attribution.
• Gold-tier 3D models fall under CC BY 4.0 license and are available only to Gold plan subscribers. Commercial use is permitted with attribution.

17. API Key Credentials

If you obtain API Keys through the Platform, the following obligations apply in addition to the general Account security obligations above:

• You must store API Keys securely, for example using environment variables, secrets managers, or secure configuration systems. You must never hard-code API Keys in source code or commit them to version control repositories.
• You must use API Keys only in server-to-server communication. You must never expose API Keys in client-side JavaScript, mobile applications, or browser requests where they may be intercepted.
• You must not share, sell, publish, or distribute your API Keys to unauthorized third parties.
• You must notify the Company immediately at info@bitbybit.dev if you suspect an API Key has been compromised. You should rotate your API Key promptly after any suspected compromise using the Studio dashboard.
• You are solely responsible for all usage and charges incurred under your API Key, including unauthorized usage resulting from your failure to secure the key.

The Company reserves the right to revoke any API Key that it reasonably believes has been compromised or is being used in violation of these Terms and Conditions.

18. API Services

The API Services provide server-side 3D geometry processing capabilities accessible via API endpoints. API Services include, but are not limited to: executing CAD operations (booleans, fillets, chamfers, sweeps, lofts, and similar), generating parametric 3D models, converting between file formats (STEP, GLTF, STL, and others), and running asynchronous computation tasks.

Access to API Services requires an active API Key subscription. API Key subscriptions are separate from and independent of Editor plan subscriptions (Free, Silver, Gold). Holding an Editor plan does not grant API access, and holding an API Key plan does not grant Editor plan features.

The API Services process your data on managed server infrastructure. Processing results are stored temporarily and are subject to automated cleanup as described in the Data Processing and Retention section.

19. Usage Limits and Fair Use

Each API Key plan includes defined usage limits, including but not limited to: compute minutes per billing cycle, maximum concurrent tasks, and maximum file size per upload. These limits are enforced automatically.

When you exceed your included compute allocation:

• On plans with a hard cap (currently the Starter plan): requests are rejected when the compute allocation is exhausted. No overage charges apply.
• On plans with overage billing (currently the Professional and Business plans): additional usage beyond the included allocation is charged at the overage rate specified in your plan, up to the monthly spending cap specified in your plan. Once the spending cap is reached, further requests are rejected until the next billing cycle.
• On Enterprise plans: billing and overage terms are governed by your individual enterprise agreement.

You are responsible for monitoring your usage through the Studio dashboard. While we endeavor to provide accurate real-time usage data, billing is based on server-side metering, which is authoritative and may differ slightly from dashboard estimates.

The Company reserves the right to throttle or temporarily suspend API access if usage patterns indicate abuse, including but not limited to: sending requests designed to consume disproportionate compute resources, opening excessive concurrent connections, or submitting malformed inputs intended to degrade service performance.

The Company is not liable for interrupted service resulting from exhaustion of your compute allocation or spending cap.

20. Enterprise Plans, Tenant Deployments, and Custom Development

Enterprise Plans

Enterprise plan subscribers operate under an Enterprise Agreement that may supplement or modify specific commercial provisions of these Terms and Conditions. Where an Enterprise Agreement conflicts with these Terms and Conditions, the Enterprise Agreement prevails - but only for the specific Enterprise client, only to the extent expressly stated in that agreement, and only for provisions that are not designated as non-overridable below. All provisions of these Terms and Conditions that are not explicitly modified by the Enterprise Agreement remain in full force.

Non-overridable provisions. The following provisions of these Terms and Conditions may not be modified, waived, or overridden by any Enterprise Agreement, Custom Development agreement, or other side agreement:

• Platform intellectual property. The Company's exclusive ownership of the Platform, Shared Infrastructure, processing engines, source code, architecture, internal APIs, orchestration systems, and all related intellectual property (as described in §4 "Our License to You") may not be transferred, shared, or diminished by any agreement.
• Strictly forbidden activities. The prohibitions listed in §8 "Strictly Forbidden" apply to all users including Enterprise clients and may not be waived.
• Governing law. These Terms and Conditions are governed by Lithuanian law (§31 "Governing Law and General Provisions") and this may not be changed by an Enterprise Agreement.
• Indemnification. The indemnification obligations in §30 "Indemnification" apply to all users and may not be reversed or removed.
• Harmful Content. The restrictions on Harmful Content (§6) apply to all Content and API Data processed under any agreement.

What Enterprise Agreements may modify. All Enterprise Agreements must be executed by an authorized representative of the Company. Enterprise Agreements may adjust the following types of provisions: pricing and billing terms, usage limits and overage rates, service level commitments and uptime guarantees, support response times, data retention periods, processing location requirements, and confidentiality terms. Any modification beyond this scope must be explicitly identified and separately approved in writing.

Tenant Configurations on Shared Infrastructure

The Company may deploy Tenant Configurations - client-specific code, scripts, processing parameters, or workflow configurations - to its Shared Infrastructure on behalf of Enterprise clients. This means that custom processing logic for a specific client runs on the same underlying servers, networking, and storage systems used by other clients.

The following terms apply to Tenant Configurations:

• Logical isolation, not physical isolation. Tenant Configurations are logically separated but share underlying compute, storage, and networking resources with other tenants. The Company does not guarantee physical isolation of infrastructure unless explicitly agreed in an Enterprise Agreement.
• Platform ownership. All infrastructure, frameworks, libraries, orchestration systems, base processing engines, and platform code used to run Tenant Configurations remain the exclusive intellectual property of the Company. Deploying a Tenant Configuration does not transfer any ownership of or rights to the underlying Platform, Shared Infrastructure, or any other component of the Company's technology stack.
• Tenant Configuration ownership. Unless otherwise specified in the Enterprise Agreement:
  • Custom scripts, parameters, and processing logic that are specific to the client and developed exclusively for that client are owned by the client.
  • Any reusable components, libraries, tools, frameworks, or general-purpose improvements created during Custom Development remain the intellectual property of the Company and may be used for other clients or incorporated into the Platform.
  • The Company retains a perpetual, royalty-free license to use any general techniques, know-how, or methods learned during Custom Development, provided this does not include disclosure of the client's confidential business data.
• No access to other tenants. You may not attempt to access, inspect, interfere with, or extract data from Tenant Configurations, workloads, or data belonging to other clients on the Shared Infrastructure.
• Deployment and removal. The Company has sole discretion over when and how Tenant Configurations are deployed, updated, or removed from the Shared Infrastructure. Upon termination of your Enterprise Agreement or API Key subscription, the Company will remove your Tenant Configuration from the Shared Infrastructure within a commercially reasonable timeframe.
• No guaranteed performance isolation. While the Company takes reasonable measures to prevent one tenant's workload from degrading service for others, the Company does not guarantee that Shared Infrastructure performance will be unaffected by other tenants' usage. Performance guarantees, if any, must be specified in the Enterprise Agreement.

Custom Software Development

The Company may enter into separate agreements with clients for custom software development, integrations, or bespoke processing workflows. The following terms apply to all Custom Development unless explicitly overridden by the applicable agreement:

• Separate agreement required. Custom Development is always governed by a separate written agreement that specifies scope, deliverables, timelines, pricing, and intellectual property ownership. These Terms and Conditions alone do not create any obligation for the Company to perform Custom Development.
• Platform protection. No Custom Development agreement grants the client any rights to the Platform's source code, architecture, internal APIs, deployment infrastructure, or proprietary processing engines. Custom Development builds on top of the Platform - it does not transfer ownership of the Platform or any part thereof.
• Derivative works. If Custom Development produces components that are tightly integrated with the Platform and cannot function independently of the Company's proprietary systems, those components are considered derivative works of the Platform and remain the intellectual property of the Company unless the Enterprise Agreement explicitly states otherwise.
• Independence of agreements. Termination of a Custom Development agreement does not terminate the client's API Key subscription or these Terms and Conditions, and vice versa, unless explicitly stated in the relevant agreement.
• Confidentiality. Both parties agree to treat confidential information exchanged during Custom Development (including but not limited to business logic, trade secrets, system architecture details, and client data) as confidential. Specific confidentiality terms, including duration and exceptions, should be defined in the Enterprise Agreement or a separate NDA.

21. Data Processing and Retention

When you use the API Services, you may upload files and submit data for processing. The Company processes this data solely to provide the API Services and does not access, use, or share your data for any other purpose beyond what is necessary to deliver the service.

Retention: Files uploaded for processing and computation results are stored temporarily on cloud infrastructure. Results of asynchronous tasks are retained for a limited period (currently 24 hours) after which they are automatically deleted. You are responsible for downloading results within this retention window. The Company may change the retention period at any time with reasonable notice.

Processing location: The Company's primary infrastructure is located in the European Union. However, API Data may also be processed on servers outside the EU - including, but not limited to, compute nodes operated by the Company's infrastructure providers in other regions - in order to reduce latency and improve performance for geographically distributed clients. Where personal data is transferred outside the European Economic Area, the Company relies on appropriate safeguards as required by GDPR Chapter V, such as the European Commission's Standard Contractual Clauses or an adequacy decision, as applicable.

Subprocessors: The API Services use third-party infrastructure providers for data processing, including cloud compute and networking providers, and a billing provider. A current list of subprocessors is available upon request by contacting info@bitbybit.dev.

GDPR: For the purposes of the EU General Data Protection Regulation (GDPR), when you submit personal data through the API Services for processing, the Company acts as a data processor on your behalf. The data processing terms described in this section, together with our Privacy Policy, constitute the data processing agreement required under Article 28 GDPR. Specifically:

• The Company processes personal data only on your documented instructions (i.e., the API calls you make).
• The Company ensures that persons authorized to process the personal data have committed themselves to confidentiality.
• The Company takes appropriate technical and organizational security measures, including encryption in transit, access controls, and secure credential management.
• The Company will notify you without undue delay after becoming aware of a personal data breach affecting your API Data.
• The Company will delete or return all personal data after the end of the provision of services, as described in the retention terms above.

22. Payments, Refunds, Upgrades, and Downgrades

Editor Plans (Silver and Gold)

Silver and Gold Editor Plans offered on the Platform are paid monthly or yearly. Our payment system uses partner platform Stripe to process and manage payments. In order to do that we share information about you with Stripe. This happens only when you opt-in for our paid plans. Make sure you read and understand Stripe's Terms of Service and Privacy Policy before you purchase our plans.

We do not offer refunds or compensations. Whether you decide not to use our Silver or Gold plans, use our Services partially, or if you are dissatisfied with the features offered in our paid plans, we do not compensate or refund you for that. We offer a Free plan for you to test out the main features of the Platform and we believe this gives you a chance to understand the Platform and its features before you pay us. That is why we do not offer refunds. You are free to cancel your subscription at any time. All sales are final.

We use Stripe to pay taxes in other countries. Sales tax, VAT, and GST are paid by us.

When you downgrade your plan from Gold to Silver, from Silver to Free, or from Gold to Free, you risk losing your data, access to features, and capacity of quota limits. You agree that this risk is yours exclusively. If you reach the limits of the lower-graded plan, we may clean up your Projects, Assets, or Scripts from your account to comply with the quota limits of that plan. If you do not want to lose data that is important, you can clean up your Projects yourself before the plan expires. The Company will not accept any liability for such loss or related damages that may occur when downgrading your plan.

API Key Plans (Starter, Professional, Business, Enterprise)

API Key Plans are billed separately from Editor Plans via Stripe on a monthly cycle. Usage limits and overage handling are described in §19 (Usage Limits and Fair Use).

API Key Plan subscriptions are non-refundable. Overage charges already incurred are non-refundable. If you cancel your API Key subscription, your API Key remains functional until the end of the current billing period, after which it is revoked. All no-refund and no-compensation terms described in this section apply equally to API Key Plans.

EU Consumer Right of Withdrawal

For consumers in the European Union: under Directive 2011/83/EU you may have a 14-day right of withdrawal for digital content and services purchased online. By requesting and receiving immediate access to the digital content and Services upon purchase, you expressly consent to the immediate supply of digital content and the commencement of the service before the withdrawal period has expired, and you acknowledge that you thereby lose your right of withdrawal. For Editor Plans, this consent is given when you first access paid features. For API Key Plans, commencement of service occurs upon issuance of your API Key.

23. Service Availability

The Company does not guarantee any specific level of availability or uptime for the Platform or API Services. Planned maintenance windows will be communicated via the Studio dashboard or the Platform when commercially reasonable. The Services may be temporarily unavailable due to infrastructure updates, security patches, or third-party provider outages.

Enterprise plan subscribers may negotiate specific service level commitments under a separate written agreement.

24. Changes to Pricing, Plans, Quotas, Features, the Platform, and These Terms and Conditions

The Company reserves the full right for any reason at any time to temporarily or permanently stop or discontinue the Platform and our Services. We have the right to do that for the whole Platform or parts of it. You agree that we can do that with or without notice and we will not be held liable for any damages that may occur in relation to such an event.

The Company will not be held liable for changes to the Platform that disturb your work, negatively affect your Content, or stop your code in the Scripts from working correctly. You also agree that we are not liable for discontinued service, stopped or paused Platform either to you, other users, or third parties that may be affected by such an event. You agree that you will not be compensated if such an event occurs.

The Company reserves the right to change any prices, plans, or quota limits. We will inform you about price changes on our homepage when that happens or when such changes are about to happen. We do our best to be transparent and keep you informed.

API pricing changes: Changes to API Key Plan pricing, overage rates, or spending caps will take effect at the start of the next billing cycle following the date of notice. In-cycle pricing will not be changed retroactively. The Company will provide at least 14 calendar days' notice before any price increase affecting API Key Plans.

When we make major changes to these Terms we release a new version. You will be asked to review and accept the updated version before continuing to use the Services. Continued use after acceptance means you agree with the updated Terms. If you disagree, you should stop using the Platform and delete your Account.

25. Deleting Your Account

You can delete your account at any time through your account settings. If for some reason you cannot complete the process, contact us at info@bitbybit.dev from the email address registered on the Platform.

Deletion of your Account is immediate and irreversible. All data associated with your Account after deletion will be lost forever. The Company will not be able to retrieve it. You agree that the Company may retain information in two forms after account deletion: (a) database backups, which are overwritten through normal backup rotation within approximately 90 days; and (b) specific legal and compliance records — such as transaction history, billing records, and account identifiers — which may be retained for up to 10 years where required for tax, legal, or regulatory purposes. Archived records are not used for active processing and are not shared with third parties except as required by law.

If you delete your Account while still being an active Silver, Gold, or API Key plan holder, you will not be compensated for the remaining time period during which you will not use the Platform. After you delete your account you will be removed from any mailing lists that we may have and you will not be charged any additional costs afterwards when your plans expire. If you decide to register again you will have to purchase a plan of your choice again. All plans expire immediately with the removal of your Account. It is not possible to reassign plans of deleted Accounts to newly registered or existing Accounts even if they come from the same email or third-party authentication provider.

API Account Cleanup: If you have active API Key subscriptions, deleting your Account will immediately revoke all API Keys, cancel all active subscriptions, and delete all files and task results associated with your API account. Any overage charges incurred before deletion remain payable. Deleted API Keys cannot be recovered or reassigned.

26. We Have the Right to Investigate and Terminate Your Account

The Company has the legal right to investigate any violations of these Terms and Conditions and may cooperate with law enforcement agencies and authorities in prosecuting users who violate them. While we are not obligated to monitor all Content on the Platform, we reserve the right to review, track, and monitor Content at our discretion. The Company may remove any Content that, in our judgment, violates these Terms without prior notice or warning.

You agree that the Company has the right to delete your Account and all of the information therein:

• If you breach these Terms and Conditions.
• If your bandwidth usage significantly exceeds that of the average user of the Platform.
• If you upload Asset files that are not related to your Projects, Scripts, or things that are allowed on the Platform.
• If your Assets contain viruses or malicious software.
• If you use the API Services to process content that violates these Terms and Conditions.
• If you attempt to circumvent rate limits, spending caps, or usage quotas through technical means.
• If your API usage patterns indicate automated abuse, credential stuffing, or denial-of-service activity.
• If you share, sell, or distribute your API Keys to unauthorized third parties.

After we detect any of such violations we may delete your Account immediately and irreversibly. We will not be able or willing to recover any data related to that Account and we will not provide any services to you. You agree that the Company may keep the information related to such an account for some time in our archived backups of the database.
