Terms of Service

1. Description of the Service

Twins provides a cloud-based platform that enables users to clone, transfer, and synchronize data between Supabase database projects ("the Service"). The Service includes, but is not limited to: database schema cloning, row-level data transfer, storage bucket cloning, edge function deployment, authentication configuration transfer, cron job synchronization, and scheduled automated cloning.

Twins acts exclusively as a technical tool and intermediary. We do not own, control, endorse, or assume any responsibility for the data that flows through our platform. You retain full ownership of and responsibility for your data at all times. The Service is designed to facilitate operations that you initiate and control — Twins does not independently decide what data to process.

2. Account Registration and Security

To use the Service, you must create an account and provide accurate, complete, and current information. You are solely responsible for:

• Maintaining the confidentiality of your account credentials, including passwords, API keys, access tokens, and OAuth tokens used to connect to your Supabase projects.
• All activities that occur under your account, whether or not authorized by you, including actions taken by third parties using your credentials.
• Ensuring that your account information remains accurate and up to date.
• Notifying us immediately at security@twins.dev of any unauthorized use of your account or any other breach of security.

Twins shall not be liable for any loss or damage arising from your failure to comply with these security obligations or from unauthorized access to your account resulting from your negligence, including but not limited to sharing credentials, using weak passwords, or failing to enable available security features.

You may not share your account with multiple individuals. Each individual user must have their own account. You may not create accounts through automated means or under false or fraudulent pretenses.

3. User Responsibilities and Data Ownership

You represent and warrant that:

• You have the legal right, authority, and all necessary permissions to access, transfer, and clone all data processed through the Service.
• Your use of the Service complies with all applicable laws, regulations, and third-party agreements — including but not limited to your agreement with Supabase, Inc.
• You will not use the Service to process, store, or transfer any data that you do not have the lawful right to handle.
• You are solely responsible for the content, quality, accuracy, legality, and appropriateness of all data you process through the Service ("Customer Data").
• You have obtained all necessary consents, authorizations, and legal bases from data subjects whose personal data may be included in your databases.
• You have properly configured your Supabase projects, including security settings, access controls, and resource provisioning, before initiating any clone operation.

3.1 Data Controller Designation

You acknowledge that you are the data controller (as defined under Regulation (EU) 2016/679 — the "GDPR") for all personal data contained in your Customer Data. Twins acts as a data processor on your behalf, processing Customer Data solely in accordance with your documented instructions (i.e., the cloning operations you initiate through the Service interface).

You are solely responsible for determining the lawfulness of processing, providing privacy notices to data subjects, conducting Data Protection Impact Assessments (DPIAs) where required, and responding to data subject requests relating to data contained in your databases. Twins has no obligation to identify or respond to data subject requests concerning Customer Data.

3.2 Prohibited Data Categories

Unless you have entered into a separate written agreement with Twins that specifically authorizes it, you shall not use the Service to process:

• Payment card data subject to PCI DSS (cardholder data, track data, CVV/CVC codes).
• Protected health information (PHI) subject to HIPAA or equivalent healthcare regulations.
• GDPR special category data (Article 9): racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, genetic data, biometric data for identification, health data, sex life or sexual orientation data.
• Data subject to export control laws, including but not limited to the U.S. Export Administration Regulations (EAR), International Traffic in Arms Regulations (ITAR), or EU Dual-Use Regulation.
• Government classified information or data subject to regulatory requirements that prohibit cloud processing.

If you process any of the above categories of data through the Service without authorization, you do so entirely at your own risk. Twins accepts no liability for any regulatory penalties, claims, or damages arising from such unauthorized processing.

4. Acceptable Use Policy

You agree not to use the Service to:

• Violate any applicable local, national, or international law or regulation.
• Transfer data that infringes upon the intellectual property rights, privacy rights, or other rights of any third party.
• Clone or transfer databases containing data you are not authorized to access or process.
• Attempt to gain unauthorized access to any part of the Service, other accounts, computer systems, or networks connected to the Service.
• Interfere with or disrupt the integrity or performance of the Service, including introducing malicious code, viruses, or harmful scripts.
• Use the Service for competitive benchmarking, reverse engineering, or to build a competing product or service.
• Circumvent or attempt to circumvent any usage limits, rate limits, quotas, or access controls imposed by the Service.
• Resell, sublicense, or provide the Service to third parties without our prior written consent.
• Use the Service to store or transfer unlawful, defamatory, harassing, or fraudulent content.
• Use the Service in any manner that could damage, disable, overburden, or impair our infrastructure or the infrastructure of our third-party providers.
• Use automated means (bots, crawlers, scrapers) to access the Service except through APIs we explicitly provide.
• Use the Service for cryptocurrency mining or other resource-intensive activities unrelated to data cloning.
• Use the Service in connection with life-critical systems, nuclear facilities, air traffic control, or weapons systems.

Violation of this Acceptable Use Policy may result in immediate suspension or termination of your account and access to the Service, without notice or refund. We reserve the right to investigate violations, cooperate with law enforcement authorities, and report violations to appropriate regulatory bodies.

5. Data Processing and Transient Access

During a cloning operation, Twins temporarily reads data from your source Supabase project and writes it to your designated target Supabase project. This data is processed in transit and is not stored, cached, logged, or retained on Twins infrastructure beyond what is strictly necessary to complete the operation.

5.1 Metadata Storage

Twins stores metadata related to your cloning operations (such as job status, timestamps, table names, row counts, error messages, and clone configuration options) for the purpose of providing the Service, displaying job history, and debugging. This metadata does not include the actual content of your database rows or any personally identifiable information from your databases.

5.2 Access Grant

You acknowledge that the Service requires read access to your source database and write access to your target database. You grant Twins a limited, revocable, non-exclusive right to access your Supabase projects solely for the purpose of performing the cloning operations you initiate. This access is exercised through the OAuth tokens you provide and can be revoked at any time by disconnecting your projects from the Twins platform.

5.3 Aggregated and Anonymized Data

Twins may generate and use aggregated, anonymized, and de-identified data derived from your use of the Service (e.g., aggregate clone success rates, average operation durations, feature usage statistics). Such data does not identify you or any individual and is not considered Customer Data. Twins retains all rights to use such aggregated data for any lawful purpose, including analytics, benchmarking, service improvement, and reporting.

6. Backups and Data Integrity

You acknowledge and agree that:

• Before any clone operation: You will create a complete, independent backup of both your source and target databases using Supabase's built-in backup features or your own backup solution.
• Permissions and quotas: You will verify that you have sufficient permissions, storage quotas, and resource allocations on both Supabase projects.
• Preview verification: You will review and confirm the scope of the cloning operation using the preview feature before initiating the clone.
• Post-clone verification: You will verify the results of the cloning operation using the verification feature provided by the Service and independently confirm the integrity of the transferred data.
• Target database impact: Clone operations write to your target database and may overwrite, modify, or delete existing data in the target. You are solely responsible for understanding and accepting the impact on your target database.
• No rollback guarantee: Twins does not provide automatic rollback capabilities. If a clone operation produces undesired results, you are responsible for restoring from your own backups.

7. Service Availability and SLA

7.1 Availability

Twins will use commercially reasonable efforts to make the Service available, but we do not guarantee any specific level of uptime, availability, or performance. The Service is provided without any Service Level Agreement (SLA) unless a separate, written SLA has been executed between you and Twins.

The Service may be subject to limitations, delays, outages, and other problems inherent in the use of the internet, electronic communications, and cloud infrastructure. You acknowledge that:

• The Service may be unavailable from time to time due to maintenance (scheduled or unscheduled), updates, upgrades, or infrastructure changes.
• The Service depends on third-party infrastructure providers (including Supabase, Vercel, Railway, and their underlying cloud providers such as AWS). Outages or performance degradation of these providers will directly affect the Service.
• Network conditions, DNS propagation, API rate limits, and other external factors may affect the performance and availability of the Service.
• Clone operations involving large datasets may take extended periods to complete and may be subject to timeouts or interruptions.

7.2 No SLA — Sole Remedy

7.3 Service Modifications

We reserve the right to modify, update, suspend, or discontinue the Service (or any part, feature, or functionality thereof) at any time, with or without notice. We will make reasonable efforts to provide advance notice of material changes, but this is not always practical, particularly for changes driven by security concerns, legal requirements, or third-party provider changes. We shall not be liable to you or to any third party for any modification, price change, suspension, or discontinuance of the Service.

8. Service Suspension

Twins may suspend your access to the Service, in whole or in part, immediately and without prior notice, if we reasonably determine that:

• Your use of the Service poses a security threat to the Service or any third party.
• Your use of the Service may adversely impact the Service, our systems, or other users.
• Your use of the Service may subject Twins to liability.
• You are in breach of these Terms, including the Acceptable Use Policy.
• You have failed to pay applicable fees when due.
• Your use of the Service is suspected to be fraudulent or illegal.
• Suspension is required by law, regulation, or a court or governmental order.
• Our third-party providers (including Supabase) have suspended or terminated the services upon which the Service depends.

TWINS WILL HAVE NO LIABILITY FOR ANY DAMAGE, LOSS, OR EXPENSE THAT YOU OR ANY THIRD PARTY MAY INCUR AS A RESULT OF A SERVICE SUSPENSION. We will use reasonable efforts to notify you of the reason for suspension and, where applicable, provide you with an opportunity to cure the underlying issue.

9. Third-Party Services and Dependencies

The Service integrates with and critically depends upon third-party services, including but not limited to:

• Supabase Inc. — Database hosting, authentication, edge functions, Management API, and storage.
• Vercel Inc. — Frontend hosting and content delivery network (CDN).
• Railway Corp. — Clone worker infrastructure and background processing.
• Stripe Inc. — Payment processing and billing management.
• Underlying cloud providers — Including Amazon Web Services (AWS), Google Cloud Platform (GCP), and Cloudflare, which provide the infrastructure for the services listed above.

Your use of these third-party services is subject to their respective terms of service and privacy policies. You are responsible for reviewing and complying with the terms of any third-party service you use in connection with Twins.

Twins is not responsible for the availability, reliability, security, performance, or conduct of any third-party service. Any changes, outages, interruptions, rate limit changes, API deprecations, pricing changes, or discontinuations of third-party services that affect the functionality of Twins shall not constitute a breach of these Terms. In particular, outages of Supabase, AWS, or any underlying infrastructure provider are entirely outside Twins's control and are excluded from any liability, warranty, or service level commitment.

10. Fees and Payment

10.1 Pricing

Certain features of the Service are subject to fees as specified in the applicable pricing plan displayed on the Twins platform. All fees are quoted in the currency indicated on the pricing page and are exclusive of applicable taxes unless otherwise stated.

10.2 Payment Processing

Payments are processed by Stripe, Inc. By providing payment information, you authorize Twins and Stripe to charge the applicable fees to your designated payment method. You are responsible for ensuring that your payment information is accurate and current.

10.3 Non-Refundable Fees

All fees are non-refundable except as expressly provided in these Terms or as required by applicable law. Failed clone operations, service interruptions, or dissatisfaction with the results of a clone operation do not entitle you to a refund.

10.4 Price Changes

We reserve the right to change our pricing at any time. We will provide at least thirty (30) days' notice of any price increase. Your continued use of the Service after the effective date of a price change constitutes acceptance of the new pricing. If you do not agree to a price change, your sole remedy is to terminate your account before the change takes effect.

10.5 Overdue Payments

If any fees are not paid when due, Twins may (a) charge interest on overdue amounts at the lesser of 1.5% per month or the maximum rate permitted by applicable law, (b) suspend your access to the Service until all outstanding amounts are paid, or (c) terminate your account. You are responsible for all costs of collection, including reasonable attorneys' fees.

11. Intellectual Property

11.1 Twins IP

Twins shall own and retain all right, title, and interest in and to the Service, including all software, technology, algorithms, user interfaces, designs, trade names, trademarks, service marks, logos, and all intellectual property rights therein ("Twins IP"). Nothing in these Terms grants you any right, title, or interest in the Twins IP except for the limited license to use the Service as expressly set forth herein.

11.2 Customer Data

You retain all right, title, and interest in and to your Customer Data. You grant Twins a worldwide, non-exclusive, royalty-free, limited license to access, use, process, and transmit your Customer Data solely as necessary to provide the Service in accordance with these Terms. This license terminates when you delete your Customer Data or terminate your account.

11.3 Feedback

If you provide any suggestions, ideas, enhancement requests, recommendations, or other feedback regarding the Service ("Feedback"), you grant Twins a perpetual, irrevocable, non-exclusive, royalty-free, worldwide license to use, modify, and incorporate such Feedback into the Service without any obligation to you. Feedback is not confidential information.

12. Beta Features and Previews

Twins may offer certain features, functionalities, or services that are designated as "beta", "preview", "experimental", or "early access" ("Beta Features"). Beta Features are provided for evaluation purposes only and may be changed, suspended, or discontinued at any time without notice.

Beta Features are provided "AS IS" without any warranty, SLA, support obligation, or liability of any kind. You use Beta Features entirely at your own risk. We recommend that you do not use Beta Features with production data or for critical operations.

13. Disclaimer of Warranties

14. Limitation of Liability

15. Indemnification

You agree to indemnify, defend, and hold harmless the Twins Parties from and against any and all claims, demands, actions, liabilities, damages (actual and consequential), losses, costs, and expenses (including reasonable attorneys' fees, court costs, and expert witness fees) arising out of or relating to:

• Your use of the Service, including any actions taken by third parties using your account.
• Your violation of these Terms, including the Acceptable Use Policy.
• Your violation of any applicable law, regulation, or third-party agreement.

• Any regulatory fines, penalties, or sanctions imposed in connection with data you process through the Service.
• Any dispute between you and a third party (including Supabase) relating to data transferred through the Service.
• Your negligence, wilful misconduct, or fraud.

Twins will provide you with prompt written notice of any claim subject to indemnification. However, failure to provide such notice shall not eliminate or reduce your indemnification obligations, except to the extent that the failure to provide notice materially prejudices your defense. You shall not settle any claim without Twins's prior written consent if the settlement would impose any obligation on Twins or admit liability on behalf of Twins.

16. Termination

16.1 Termination by You

You may terminate your account at any time by contacting us at support@twins.dev or through the account settings. Termination does not entitle you to a refund of any fees already paid or relieve you of any obligation to pay fees that have already accrued.

16.2 Termination by Twins

We may suspend or terminate your access to the Service:

• For cause: Immediately upon notice if you breach the Acceptable Use Policy, violate applicable law, fail to pay fees within ten (10) days of notice of non-payment, or if continued provision of the Service would subject Twins to liability.

17. Dispute Resolution

17.1 Informal Resolution

Before initiating any formal dispute resolution proceedings, you agree to first attempt to resolve any dispute informally by contacting us at legal@twins.dev. We will attempt to resolve the dispute informally within thirty (30) days of receiving your notice.

17.2 Arbitration

If a dispute cannot be resolved informally, you and Twins agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service shall be resolved by binding individual arbitration administered by the International Chamber of Commerce (ICC) in accordance with its rules. The arbitration shall be conducted in English, with the seat of arbitration in Paris, France. The arbitral tribunal shall consist of a single arbitrator.

17.3 Class Action and Jury Waiver

17.4 Injunctive Relief

Notwithstanding the foregoing, Twins retains the right to seek injunctive or other equitable relief in any court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of Twins's intellectual property rights, confidential information, or data security.

18. Governing Law

These Terms shall be governed by and construed in accordance with the laws of France, without regard to its conflict of law provisions. To the extent that arbitration is not applicable or is deemed unenforceable, you irrevocably consent to the exclusive jurisdiction and venue of the courts of Paris, France.

The application of the United Nations Convention on Contracts for the International Sale of Goods (CISG) is expressly excluded.

19. Export Controls and Compliance

You represent and warrant that you are not located in, or a national or resident of, any country that is subject to EU, U.S., or other applicable trade sanctions or embargoes, and that you are not on any sanctioned party list. You agree to comply with all applicable export control laws, trade sanctions, and import laws, including the EU regulations, U.S. Export Administration Regulations (EAR), and the sanctions programs administered by the U.S. Office of Foreign Assets Control (OFAC).

You shall not access or use the Service from any territory subject to comprehensive sanctions, and you shall not provide access to the Service to any person or entity on a restricted party list.

20. Modifications to the Terms

Twins reserves the right to modify these Terms at any time. We will notify you of material changes by posting the updated Terms on the platform, updating the "Last updated" date, and, where practicable, sending you an email notification. Your continued use of the Service after such changes take effect constitutes acceptance of the modified Terms.

If you do not agree to the modified Terms, your sole remedy is to terminate your account before the modifications take effect. Disputes arising under prior versions of these Terms will be resolved under the version in effect at the time the dispute arose.

21. Severability and Waiver

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, that provision will be enforced to the maximum extent permissible, and the remaining provisions will continue in full force and effect. The invalid provision shall be replaced by a valid provision that most closely achieves the economic, legal, and commercial objectives of the invalid provision.

The failure of Twins to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by an authorized representative of Twins.

22. Force Majeure

Twins shall not be liable for any failure or delay in performing its obligations under these Terms (except for any obligations to make payments) if and to the extent such failure or delay is caused by circumstances beyond its reasonable control, including but not limited to:

• Cyberattacks, distributed denial-of-service (DDoS) attacks, or zero-day vulnerabilities in third-party software.
• Changes in applicable laws, regulations, or governmental policies that prevent performance.
• Fire, explosion, or equipment failure.

During a force majeure event, Twins's obligations under these Terms will be suspended for the duration of the event. If a force majeure event continues for more than ninety (90) days, either party may terminate the affected portion of the Agreement by written notice.

23. Entire Agreement

These Terms, together with the Privacy & Data Protection Policy, the Legal Notice, and any other legal documents referenced herein or published by Twins on the platform, constitute the entire agreement between you and Twins regarding the use of the Service. These Terms supersede all prior or contemporaneous communications, proposals, negotiations, and agreements, whether oral or written, relating to the same subject matter.

No terms or conditions contained in any purchase order, order form, or other document submitted by you shall modify or supplement these Terms, and any such terms are expressly rejected.

24. Assignment

You may not assign or transfer these Terms, or any rights or obligations hereunder, without Twins's prior written consent.
