One of One

Privacy Policy

Last updated: 26 July 2026 · Effective: 26 July 2026

This Privacy Policy explains what the One of One app ("the App") collects, how it is used and shared, and your choices.

1. What we collect

When you use the system share sheet, the App may make a temporary local copy of pet art on your device. The App does not collect the destination you choose in the share sheet.

2. How we use it

3. Third-party AI processing and your permission

Before a user-started AI action, the App explains what will be shared and asks you to explicitly agree. If you decline, the AI action does not start and the data is not sent for that request.

When you agree, One of One sends only the data needed to create, check, and return the result:

One of One does not send this AI-request data to these providers for advertising or cross-app tracking. Their processing is limited to providing the requested service under our service-provider arrangements.

4. Other service providers

Supabase provides authentication, database, server functions, and private storage. RevenueCat manages subscription entitlements and the authoritative Sparks balance. PostHog receives the product and attribution events described above. Apple processes App Store purchases and provides attribution. If you grant tracking permission, Meta receives the limited advertising-measurement data described above. We do not sell your personal data.

5. Storage, retention, and security

Your account, pet data, and accepted Life Book media are stored privately and associated with your account, not posted publicly. We keep them while your account is active so your pet remains a continuous biography. Operational purchase records and analytics may be retained as needed for security, billing reconciliation, abuse prevention, and product measurement.

6. Your choices

7. Account and data deletion

In-app account deletion removes your account identity, owner-scoped pet records, and private pet media from active systems. Limited records may be retained where required for legal, security, fraud prevention, or billing purposes. Deleting the account does not cancel an Apple subscription; subscriptions are managed separately through Apple.

8. Children

The App is not directed to children under 13, and we do not knowingly collect personal information from them.

9. Changes

We may update this Policy. The "Last updated" date reflects the current version, and material changes will be surfaced where appropriate.
