About
Less noise.
More privacy.
Built for people who just want a conversation. No ad network, no behavior tracking, no selling profiles.
Messages are sealed in the client with libsodium crypto_box before they leave the device. The server forwards and stores the encrypted packet. It cannot read the text. The private key is never uploaded.
The product is small on purpose: friends, small groups, the same model on web, desktop, and phone. If it isn’t needed to talk, it isn’t in the app.
What stays where
The secret stays with you. Delivery stays with us.

What we do not claim
Whispera is not a Signal replacement. There is no third-party audit yet, and no forward secrecy. The server can still see metadata — who messaged whom, when, and how large the packet was — just not the text.
