No Trace vs Secure Chats

Encrypted code-based chat. No phone. No email. No account. Share an 8-character code with someone. They type it in. You are talking. End-to-end encrypted from your device. Nothing to log in to. Nothing to back up. WHY NO TRACE WORKS • No phone number — no SMS confirmation that fails in your country. You install, you chat. • No email — no recovery flow you have to remember. • No account — no profile, no friend list, no directory. • 8-character code — share on paper, by voice, by QR. Whoever has the code joins. Whoever does not, never sees the room. • Optional 2-layer code — share a room without leaking access. The join-code is the second gate. • Three privacy presets — Ghost saves nothing on your phone, Balanced keeps codes for one-tap re-open, Comfort keeps history too. Change anytime. • Screen-recording lock — your chats render as black in screen recorders. • App lock — optional tap-code on every launch. • 1-tap delete all data — Settings > Account > Delete. Nothing kept on our side. HOW IT IS DIFFERENT Signal needs a phone number. Telegram needs a phone number. WhatsApp needs a phone number. Threema gives you a permanent ID that lives forever. No Trace gives you a throwaway 8-character code per room — no identity follows you. WHO PICKS IT • Journalists collecting tips • Lawyers and doctors with confidentiality duties • Activists and advocates • Two people who want a chat that does not sit in either phone's backup • Teams who want a side channel separate from work tools CROSS-DEVICE iPhone, iPad, Web, macOS, Linux. Open the room on whatever you have nearest. PRIVACY YOU CAN VERIFY • No ads • Tracking limited to crash + basic analytics, disclosed in our privacy policy • Premium uses Apple Pay only — no external payment links • Delete all your data anytime: Settings > Account > Delete CONTENT SAFETY We have zero tolerance for objectionable content and abusive users.

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. — Add friends face-to-face by scanning a QR code — keys never touch a server. — 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. What's in the app — Friends tab — your contacts, groups, pending requests, and group invitations. New activity is flagged with a small dot. — Chat tab — bubble-style conversations with copy/delete on each message, clickable URLs, and full-screen image previews. — Settings tab — language picker, message and account wipe, Banned Channels ledger for anyone you have reported and removed. Security details — Wire format: AES-256-GCM under an ECDH-derived shared secret. — At-rest format: AES-256-GCM with a per-install key, layered over every text payload and every image payload before SQLite ever sees the bytes. — Profanity filter on display names and group names, backed by a curated word list. — Open verification: the protocol and reference client are public.
