Closed testing phase
Architecture

Security built from standard cryptography.

End-to-end encryption

The relay handles encrypted message packages; message content is intended to be decrypted on participant devices.

SECRET ID

No phone number is required for messenger identity. A clean reinstall creates a new device identity.

Android Keystore

Private installation keys are generated and used on-device with Android Keystore.

Offline queue

Undelivered encrypted messages may remain queued for up to 7 days and are removed from the delivery queue after delivery.

Local protection

PIN access control and encrypted local storage protect application data on the device.

Data minimisation

No phone number or uploaded address book is required for core messaging.
