TalkRidge · Free private messenger
Private conversations. Nothing else.
TalkRidge is an end-to-end encrypted messenger with no phone number, no user directory and no ads. You add contacts by scanning each other’s QR code in person, everything you send is sealed on your device — and our servers only ever see ciphertext.

What TalkRidge is
A messenger that minds its own business
Everything you expect from a modern messenger — and none of the surveillance economics underneath it. No accounts to register, no data to monetise, nothing to leak.
Private messaging
Texts, voice notes, photos and files — end-to-end encrypted, one-to-one and in groups. Delivered through a relay that can read none of it.
Voice & video calls
Encrypted calls, one-to-one and in small groups, with the media flowing peer-to-peer between your devices wherever the networks allow.
QR-code pairing
No phone number, no directory. You add a contact by scanning each other’s code in person — the trust anchor is you, not a key server.
A server that knows nothing
The relay is a blind mailbox: it stores sealed envelopes it cannot open, and deletes them the moment they are delivered.
TalkRidge’s encryption is built exclusively from vetted, unmodified open-source cryptographic primitives, and the protocol design is documented openly. The applications have not yet undergone an independent external security audit — we say so plainly rather than borrow trust, and independent review is on the roadmap.
Inside the app
Everything a messenger needs. Nothing it doesn’t.
TalkRidge does the essentials properly instead of everything loudly — messaging, calls, groups and media, wrapped in encryption that is always on.
Chats that feel familiar
One-to-one and group conversations with forwarding, unread badges, swipe-to-mark-unread and delete-for-everyone — all end-to-end encrypted.
Calls that stay between you
Voice and video calls, plus small group calls — encrypted end to end, with the call keys exchanged over the same sealed channel as your messages.
Media & files
Photos, hold-to-record voice messages and file attachments, sealed with exactly the same encryption as your texts.
Content-free notifications
A push notification says “New message” — nothing else. Your words, names and pictures never transit a notification service.
Backup on your terms
Convenience mode keeps an encrypted backup only your keys can open; privacy mode keeps everything strictly on your device. You choose.
Groups without a server brain
Group membership and control messages are encrypted client-side and fanned out like any other message — the server never learns who is in a group.
Privacy
The best data protection is data that never exists
Most apps promise not to misuse what they collect. TalkRidge is built so there is almost nothing to collect in the first place.
No phone number
Your identity is a cryptographic keypair generated on your phone at first launch — no number, no email, no registration, nothing to link back to you.
No directory, no discovery
There is no search and no user list. Nobody can look you up, spam you, or scrape a social graph — strangers simply cannot reach you.
Sender identity stays sealed
Who a message is from lives inside the encryption, not on the envelope — designed so even our own relay learns as little as possible.
No ads, no trackers
No analytics SDKs, no advertising identifiers, no data sales. There is nothing in the app whose job is to watch you.
The protocol
Conservative cryptography, openly documented
TalkRidge composes vetted, unmodified open-source primitives into a hybrid post-quantum protocol — the custom work is in the composition, never inside a cipher.
End-to-end encryption on every message
X25519 + ML-KEM-768 hybrid key agreement
Double ratchet: forward secrecy & self-healing
XChaCha20-Poly1305 authenticated encryption
Ed25519 signed identities
QR key exchange — no key server to impersonate
Blind-mailbox relay, ciphertext only
Keys held in the iOS Keychain / Android Keystore
Vetted open-source primitives, unmodified
How it works
Two phones, two scans, nothing to sign up for
Pairing in person sounds old-fashioned — it is also the one key exchange no server, and no server breach, can ever tamper with.
Meet & scan
You and your contact scan each other’s QR codes — they carry only public keys. No number to exchange, no username to guess.
Verify the fingerprint
Both screens show the same short fingerprint. A quick glance confirms nobody swapped the codes — that moment is the entire trust model.
Talk freely
Messages are sealed on your phone, parked in a blind mailbox the server cannot read, and deleted from it the moment they are delivered.
For developers
Your servers can talk to it too, for free
TalkRidge accepts secure webhooks. An ordinary HTTP POST from your build server, your monitoring or your own product arrives as a message inside the app, on the phones that chose to receive it. No workspace to buy, no channel history sitting in the cloud.
One endpoint, one token
Post JSON with a bearer token. If it can run curl, it can reach your team: a cron job, a CI pipeline, an alerting rule, your own backend.
People subscribe by scanning
You join a bot the way you add a person: by scanning its code in the app. No invite link to leak, no member list for anyone to enumerate.
Receive only, by design
Bots push to you and cannot read back. An integration you added for alerts can never turn into a way in.
Zero plaintext
ever stored on our servers
Zero phone numbers
no identifiers to leak or sell
Zero ads or trackers
you are not the product
One job
private conversations, done properly
Not a data business
Built to protect conversations, not to collect them
Every design decision in TalkRidge starts from the same question: what happens if our servers are breached, subpoenaed or simply dishonest? The answer is designed to be “very little” — because your keys never leave your device, your contacts are yours, and the relay holds only sealed envelopes it cannot open.
No feature ships if it needs your data to work. That is a constraint — and it is the point. The app itself is free on both platforms: no subscription, no paid tier, no feature waiting behind a paywall.
