Tuijo is zero-knowledge by design. Private keys stay on your phone and never touch our servers. Even if we wanted to, we couldn't read a single line.

01 · PAIRING

You connect with a QR

You exchange only public keys by scanning a QR code. Private keys never leave the devices.

02 · ENCRYPTION

A double key per message

Each message generates a one-time AES-256 key, then encrypted with both your public keys.

03 · DELIVERY

On the server, only noise

Only encrypted data travels through the cloud. Only your two phones can decrypt and read it.

Your location is encrypted too GPS coordinates are encrypted with a per-session AES-256 key. No plaintext data ever touches the servers, and the session self-destructs when it expires.
Made for two, not for the crowd

No groups.
No strangers.
Just you.

Tuijo isn't yet another crowded chat. It's an intimate space for one person: the right one. You link one phone to the other, and that's it. A corner of the world that belongs to just the two of you.

Finally a place where it's only us talking, with no one else's notifications. It's become our direct line.

Frequently asked questions

Can Tuijo read our messages?

No. Messages are end-to-end encrypted with RSA-2048 and AES-256. Private keys stay on your device and never reach our servers. Only encrypted data travels through the cloud, unreadable to anyone but you and your partner.

How do my partner and I connect?

With a simple QR code. One phone shows the code, the other scans it, and they exchange only public keys. In seconds the two devices are securely linked.

Is shared location really private?

Yes. GPS coordinates are encrypted with an AES-256 key dedicated to the session. No plaintext location is ever stored on the server, and sharing stops on its own at the limit you choose (1 or 8 hours).
