Grafin

Grafin now supports more languages and offers a cleaner, more polished experience for encoding and decoding private text locally on your device.

Grafin is a simple, privacy-focused app for encrypting text. Turn any message or note into encrypted text in seconds. To decrypt it, the recipient needs the correct key — a key that stays in your hands.

Everything happens locally on your device. Grafin works fully offline, collects no data, and never sends your text or encryption keys anywhere. Use it to protect private notes, exchange encrypted messages while sharing the key through a separate channel, or just explore a simple way to encode and decode text.
