Data & Account Deletion
Last Updated: September 24, 2026 | Compliant with Play Store Data Safety
Self-Sovereign Identity Architecture
OffMesh does not require user registration, email addresses, phone numbers, or central cloud accounts. Your identity is represented entirely by a local Ed25519 cryptographic keypair generated directly on your mobile device.
1. How to Wipe All Data From Your Device
You can instantly and irreversibly erase all local data directly from within the OffMesh mobile application:
Launch the OffMesh application and tap the Settings icon (gear icon) in the bottom navigation bar.
Navigate to the Data & Privacy section and select Wipe All Keys & Database.
Type DELETE or confirm the biometric prompt. The application immediately overwrites and deletes the local SQLite/Isar database, purges the private Ed25519 signing key and X25519 ratchet states from the hardware Keystore, and returns the app to a fresh, uninitialized state.

3. Transient Gateway Cache Expiration Policy
If your device ever synchronized with an optional OffMesh sync gateway while internet access was present, please note:
- The gateway stores only anonymous, encrypted ciphertext envelopes. It holds no plaintext, usernames, or phone numbers.
- All envelopes are bound to a strict 7-Day Time-To-Live (TTL). Once 7 days elapse from the upload timestamp, the Redis/Postgres storage automatically drops and purges the blob permanently.
4. Manual Gateway Purge Request
If you wish to request the immediate eviction of any uncollected encrypted envelopes associated with your public key hash prior to the 7-day TTL expiration:
Send a cryptographic signature or request with your public identity fingerprint to:
Email: data-deletion@offmesh.org
Subject: OffMesh Gateway Cache Eviction Request
Requests are processed automatically by key fingerprint hash eviction within 24 hours.
