Full description

SEND is an encrypted messaging app. The account asks for no phone number and no email, and the content of your conversations can only be read by you and the person who receives it. PROTECTED MESSAGES • End-to-end encryption: messages, photos, voice notes and files can only be read by the people in the conversation. The server forwards sealed envelopes it cannot open. • The keys keep changing as you talk: if one is discovered, it does not open older messages. • Messages are encrypted with two systems together: X25519 and ML-KEM-768, a post-quantum algorithm standardized by NIST. • Disappearing messages: they delete themselves after the time you choose. • Groups: each message goes encrypted to every member, with the same encryption as one-to-one conversations. • Safety number: compare it with your contact's, by QR code or as characters, to confirm who is on the other side. PROTECTION ON YOUR PHONE • The app's own PIN, separate from your phone's unlock. • Panic PIN: when entered, it erases the keys and messages on this phone. • Disguise mode: the SEND icon can look like a calculator, weather, notes or finance app. CALLS Voice and video calls. By default, the call goes through SEND's server and the other person does not see your IP address; you can turn this option off in Settings. PLANS The free plan includes one-to-one conversations with messages, photos and files up to 5 MB. A paid plan is required for: voice and video calls, voice messages, groups and larger files. The Enterprise and Total Sovereignty plans let you use a dedicated relay or your own SEND server. Available in 15 languages.

What's new

Messages reach all your contacts again, including after a server restart. The app now repairs out-of-sync conversations on its own and resends anything left undelivered, so the “Reset Secure Session” button is no longer needed and has been removed. Unsent messages are no longer lost when you close the app.
