3. Nature of the Service

Twins provides a software tool that facilitates the cloning and transfer of data between Supabase database projects. The Service includes schema cloning, row-level data transfer, storage bucket cloning, edge function deployment, authentication configuration transfer, cron job synchronization, and scheduled automated cloning.

3.1 Technical Intermediary

Twins acts solely as a technical intermediary and does not own, control, inspect, or assume responsibility for the data processed through the platform. All data operations are performed through the Supabase Management API and Supabase client libraries. Twins does not directly access database files, storage systems, or infrastructure — all interactions are mediated through Supabase's official APIs.

3.2 Dependency on Supabase APIs

The Service is entirely dependent on the availability, reliability, and correct functioning of Supabase's APIs and infrastructure. All data read and write operations are performed through Supabase's Management API, PostgREST API, Storage API, and Auth Admin API. Twins has no direct access to the underlying PostgreSQL databases, storage buckets, or infrastructure.

If a Supabase API becomes unavailable, returns errors, behaves unexpectedly, introduces breaking changes, imposes rate limits, or experiences data integrity issues during a clone operation, Twins bears no responsibility for any resulting data loss, data corruption, incomplete transfers, or service interruptions. Such issues are attributable to Supabase and are governed by your agreement with Supabase, Inc.

3.3 No Data Retention

Twins does not store, retain, or have persistent access to your database contents. Data is read from the source project via Supabase APIs and written to the target project via Supabase APIs in real time during the cloning operation. The data transits through our worker infrastructure in-memory only and is never written to disk. No copies of your data are retained on Twins infrastructure after the operation completes or fails.

4. Intellectual Property

All content on the Twins platform — including but not limited to text, graphics, logos, icons, images, audio, video, software, source code, algorithms, user interfaces, designs, and underlying technology — is the exclusive property of Twins SAS or its licensors and is protected by applicable intellectual property laws, including copyright law, trademark law, patent law, and trade secret law.

The Twins name, logo, and all related names, logos, product and service names, designs, and slogans are trademarks of Twins SAS. You may not use such marks without the prior written permission of Twins SAS.

5. Limitation of Liability

  • Any data breach, unauthorized access, or data exposure arising from vulnerabilities in Supabase, AWS, Cloudflare, or any other third-party infrastructure provider.
  • Any failure of Supabase APIs (Management API, PostgREST, Storage API, Auth Admin API) during a clone operation, including but not limited to API errors, rate limiting, timeouts, breaking changes, or service degradation.
  • Any damage to your source database, target database, or any other system resulting from a clone operation.
  • Any loss resulting from your failure to maintain independent backups before initiating a clone operation.
  • Any regulatory penalties, fines, or sanctions arising from data processed through the platform.
  • Any service interruptions, outages, or performance degradation, regardless of duration, cause, or frequency.

Users are solely responsible for maintaining independent backups, verifying the integrity of their data before and after clone operations, and ensuring compliance with all applicable laws and regulations.

5.3 Aggregate Cap

The total aggregate liability of the Twins Parties arising out of or relating to the use of the platform shall not exceed the greater of: (a) the total amounts paid by you to Twins in the twelve (12) months preceding the event giving rise to the claim, or (b) one hundred euros (EUR 100).
