## What is Rosetta key?

Rosetta Key is a simple app for encrypting and decrypting messages using a shared phrase. Write a message, choose a secret phrase, and the app creates encrypted text that you can copy and share in other apps. Anyone who knows the same phrase can decrypt the message. Encryption happens locally on your device. The app is designed for personal and private communication and does not automatically access your chats, accounts, or messages. With Rosetta Pro, you can encrypt without limits and use a saved phrase with the Rosetta keyboard. Main features: encrypt messages, decrypt messages, use a shared phrase, Rosetta keyboard for faster writing, local processing on your device, no automatic access to messaging apps or accounts. Rosetta Key does not replace professional security advice and does not guarantee absolute security. Security also depends on the strength and secrecy of your chosen phrase.
