Proxima - Offline Messenger

Chat with friends nearby without internet or cellular service.

Offline Chat is a next-generation messenger that works via Bluetooth and Wi-Fi. No internet, no servers, no surveillance. Your messages are transmitted directly between devices and protected with end-to-end encryption.

WHEN YOU NEED IT:

At festivals and concerts — when the network is overloaded with thousands of people, Offline Chat works flawlessly. Chat with friends in the crowd, arrange to meet at the stage.

While traveling — in the mountains, on the beach, at the campsite. Where there are no cell towers, there's Offline Chat. Stay connected with companions up to 100 meters away.

In the subway and airplane — where service is unavailable or prohibited, Bluetooth always works. Exchange messages with those nearby without limitations.

During internet shutdowns — be prepared for any situation. Offline Chat requires no phone number registration and works completely autonomously.

FEATURES:

- Text messages — instant delivery to people nearby
- Voice messages — record and send with one tap
- Photo sharing — share moments without compression
- Delivery status — know when your message is delivered and read
- Typing indicator — see when someone is typing

SECURITY:

We take your privacy seriously:

- End-to-end encryption (E2E) — using Curve25519 for key exchange and AES-GCM for message encryption
- No servers — messages never leave your devices
- No registration — no phone number or email required
- No data collection — we don't know who you are or what you're saying
- Local storage — all data stays on your device

HOW IT WORKS:
