Your privacy

We can't read your messages.

Here's what PIING protects, what our servers still see, and the choices you have. For the legal detail, read our Privacy Policy.

What's protected

End to end

One-to-one chats, photos, videos and files are end-to-end encrypted. Groups and Stories too, when everyone in them has a current app. Calls are encrypted between the two phones.

Post-quantum

ML-KEM-1024 when a chat starts, ML-KEM-768 in the ongoing ratchet, so today's messages stay private tomorrow.

On your phone

Messages are saved in an encrypted database on your phone, and you can lock chats with Face ID.

Contacts

Contacts are hashed on your phone to find friends on PIING. Your address book isn't uploaded or stored. New accounts aren't findable by phone number unless they turn it on.
