Tesseract Network vs Off

Tesseract — private messaging that leaves no trail. No accounts. No phone numbers. No cloud history. Add a friend with a one-time invite code, pick an emoji for each other, and start talking. Every message is end-to-end encrypted; the relay only ever sees opaque bytes. Your identity lives in this device's secure keychain. Reinstall the app and it's gone — nothing is recoverable, from us or anyone else. What you get for free • End-to-end encrypted 1:1 chat (X25519 + AES-256-GCM) • Emoji-based contacts instead of names or numbers • Invite codes that expire in 24 hours or on first use • Notification Disguise — 10 preset alt-icons and lock-screen texts • App Lock with PIN + optional silent Duress PIN • Minimalist brutalist interface built for speed Unlock TESSERACT PLUS for the full suite • TOR ROUTING — every request tunneled through Tor; the relay sees an exit node, never you • GHOST TEXT — messages your eye reads but cameras average away • PIXEL SHATTER — text realigns only at the owner's viewing angle • CUSTOM TIMER — self-destructing messages that vanish from both phones • PHOTOS · VIDEOS · GIFS — end-to-end encrypted media • 30-DAY MAILBOX — missed messages held longer Tesseract does not have a "delete for everyone" button because there is nothing to delete. Messages don't live on a server. The relay is a dumb pipe.
