Are you the developer? Cryptographically prove you hold the key that signs it.

How trust works

Pair once with a trusted peer, a desktop or another phone, and the app keeps a private channel open between you, at home or anywhere else. Drop files or paste any text, and it lands directly on the other side. Each peer gets its own history of what went back and forth.
