Getting Started
Download Tunnel from the App Store or Google Play, open the app, and create your account. Your private key is generated automatically on your device.
Is Tunnel Free?
Yes, completely free. We don't have ads, we don't sell data, and we don't have premium tiers that lock away privacy features.
Adding Friends
Share your username or scan QR codes. We don't access your phone contacts—adding friends is always your choice.
Multiple Devices
Currently single-device only for maximum security. Multi-device support is being explored with the same security guarantees.
Account Recovery
Because your keys are stored only on your device, losing your device means starting fresh. This is by design—it ensures no one else can access your messages.
