Service providers
We share data only with the providers that run the service for us:
- Cloudflare: hosting, database (D1), photo storage (R2), caching and rate limits (KV), and real-time chat.

We may also disclose data when the law requires it, or to protect people from harm. Your data may be processed outside your country. Where it is, our providers use appropriate safeguards.
How long we keep it
- Your account and content stay until you delete them or your account.
- Sessions end when you sign out, or expire after a period of inactivity.
- When you delete your account, we remove your profile, posts, photos, comments, likes, follows and messages. Backups are overwritten within 30 days.
- We may keep reports and records we must retain by law for longer.
Your rights
Depending on where you live (for example, under the GDPR in the EU and UK, or the CCPA in California), you have the right to access, correct, download, delete or restrict the use of your data, and to object to how we use it.
- Edit your profile at any time.
