TRI1 is a private messenger built on one rule: your keys and your conversations never leave your device.

Every message, attachment, and voice or video call is end-to-end encrypted on your phone. Our servers only ever relay data they cannot read. There are no ads, no third-party trackers, and nothing to sell privacy is the product, not a setting.

WHAT YOU CAN DO
• Private 1:1 chats text, photos, files, and voice notes, all end-to-end encrypted
• Encrypted voice & video calls that ring reliably, even when the app is closed
• Group rooms for many-to-many conversations, with group voice and video
• Message tools you expect reply, forward, star, pin, edit, and delete (for you or for everyone)
• Emoji reactions
• Screenshot alerts, so you know when someone captures a disappearing moment
• Disappearing messages, per conversation

NO PHONE NUMBER NEEDED
Your identity is a key pair generated on your device, not a phone number tied to a SIM. Nothing to leak, nothing to recycle, nothing to link back to you.

TRI1 BUSINESS
Turn your identity into a public page you can share with a QR code your services, prices, opening hours, photos of your work, and the contact buttons you choose. It opens in any browser with no app required, sets no cookies, and runs no tracking scripts at all.

PRIVACY BY DESIGN THE GOLDEN RULE
• Only your PUBLIC identity is ever shared, and only with contacts you add
• Your private keys, backups, and message history stay on your device
• We cannot read your messages or calls, and we cannot recover your keys for anyone
• No ads. No advertising SDKs. No selling your data.

BUILT TO BE RELIABLE
• Messages queue and sync automatically after you reconnect
• Calls ring full-screen via secure push, even from a locked screen
• Delivered/read receipts you can turn off
• Block screenshots of the app itself, if you want to

You control your identity, your keys, and your conversations. That's the whole idea.
