Coktin Privacy Policy

Last updated: 2026-06-03

Coktin ("the app") shows a live USD↔USDT reference rate. This policy explains what data the app handles.

What we collect

Nothing, to view rates. You can open the app, use the converter, and view charts without an account or any personal data.
Email address — only if you sign in. Signing in (to save price alerts) uses a one-time magic link. Your email is stored by our authentication provider (Supabase) to identify your account.
Price alerts you create. The side, direction, and target you choose are stored so we can notify you, and are visible only to your account.
Push notification token — only if you enable alerts. If you grant notification permission, the device push token is stored to deliver notifications. Nothing is collected if you decline.

We do not collect location, contacts, advertising identifiers, or usage analytics, and we do not sell or share your data for advertising.

Solely to provide the service: authenticate sign-in, store your alerts, and send the push notifications you requested.

Supabase — database, authentication, real-time (stores email, alerts, push token).
Expo push service — delivers notifications to your device.

Your account data is kept until you ask us to delete it. To delete your account and associated data, email support@coktin.com.

Coktin is not directed to children under 13 and does not knowingly collect their data.
