TalkOnce
The message no one
else can read.
Not even us.
Everything you send — messages, calls, stories, photos — is sealed on your device and opened only on your recipient's. No phone number. No email. No name. We hold no keys and can't read your content even if compelled.
No tracking. No targeted ads. No third-party analytics or ad SDKs — anywhere in the app.
Privacy that holds up — even against a quantum computer.
Most encrypted apps protect you against today's attacker. TalkOnce is built for the one recording your traffic now to break it later.
Unreadable. By anyone.
Post-quantum end-to-end encryption on every message, call, story, and file — from the very first hello.
No number, no name
Sign up with nothing. Connect by invite link or QR code. There is no account profile to leak, subpoena, or sell.
Nothing lingers
Delivered messages are erased from our servers the moment they reach you. Anything undelivered expires within 30 days.
No tracking, ever
No ad networks, no analytics, no trackers, no data profiles. We never make money from knowing you.
A full messenger. Nothing watching over your shoulder.
Chats, groups, channels, calls, stories, GIFs, polls — the complete modern experience, without the surveillance underneath it.
Chats, groups & channels
Private conversations, groups up to 1,000 members, and broadcast channels with invite links and QR codes — all end-to-end encrypted.
Voice & video calls
Crisp one-to-one and group calls, end-to-end encrypted. If a call can't be encrypted, it doesn't connect. Period.
Stories
Share a moment that's gone in 24 hours — encrypted to your audience, never mined for a profile.
Disappearing messages
From 30 seconds to 4 weeks — or set your own custom timer. Messages erase themselves on both ends.
Media, made beautiful
A fast picker with batch sending and albums, an editor to draw, caption, and crop — and GIF search that never reveals who's searching.
Protection under pressure
A duress passcode opens a believable decoy; a panic passcode wipes everything — for the moment someone forces your phone open.
Pick how private you want to be. Change it anytime.
Every level is fully end-to-end encrypted — that never changes. These settings only change what's visible around a message, never the message itself.
- Fast, with instant push notifications
- Full features, full speed
- Best for everyday chatting
- No read receipts or typing signals
- Far less metadata around your chats
- Everyday-usable, quietly more private
- Routes through Tor — the server sees a Tor address, not your real IP
- No receipts, typing, or last-seen; link previews never fetched
- Cover traffic & size padding hide the shape of your messaging
- Calls and instant push pause (both would expose your IP)
- Turn any privacy setting on or off individually
- Mix speed and privacy to taste
- Saved, and changeable anytime
Built to be checked, not just trusted.
Real, published cryptography — and radical honesty about exactly what our servers can and can't see.
Hybrid post-quantum
Classic + post-quantum keys together (X25519 + ML-KEM-1024, Ed25519 + ML-DSA-87). Break one, the other still holds.
Sealed sender
Our servers route your messages without ever learning who sent them. Invite codes ride in link fragments we never receive.
Nothing to hide from you
We publish a plain-language ledger of exactly what our servers handle — and we're preparing for independent audit.
Privacy is free. Forever.
Full post-quantum encryption and every privacy mode are free for everyone. Optional paid plans add more room and advanced protection — never at the cost of your privacy.
