Secure Chats

Private text and photo messaging with end-to-end encryption. No phone number, no ads, no tracking. Available in seven languages on iPhone and iPad.

SecChats is a private, end-to-end encrypted messenger for one-to-one and group conversations. Every text and photo you send is encrypted on your device with AES-256-GCM under a key derived from an ECDH handshake with the recipient. The server only sees ciphertext.

No phone number. No email. No ads. No tracking.

Why SecChats

— True end-to-end encryption. Messages are encrypted on your device before they leave it and only decrypted on the recipient's. The SecChats server cannot read them. Neither can we. — No phone number or email. Sign up with a display name. The server assigns you an opaque user ID; share that with friends to start chatting. — Private by design. The on-device database is wrapped in an additional AES-256-GCM layer, so a stolen or seized device does not hand over your conversation history. — Photos, text, groups. Send messages and images to friends or groups; create groups and share QR-code invitations; scan a QR code to join a group you were invited to. — Seven languages. Switch the interface between System default, English, Romanian, Japanese, French, German, Spanish, and Brazilian Portuguese from Settings. — Open API and reference client. The protocol is documented and shipped alongside an open-source Java reference client, so you can audit or rebuild the messaging stack yourself. SecChats does not lock you in.
