About this app

Grafin is a minimalistic app for text encryption.
With just a couple of taps, any phrase turns into a secret code that can only be decrypted using a unique key known only to you.

The app works entirely offline and does not collect any data — encryption is performed locally on your device. The encryption keys are generated and accessible only to you.

Use Grafin to keep notes, send encrypted messages by sharing the unique key through an alternative communication channel, or simply experiment with coding
