Start with an invitation
No account to create. A one-time code activates your device for the private beta.
Invite only · Android beta
Make room for a simpler connection.
TAVI gives your Android phone an encrypted connection through a private server. Activate with an invitation, then connect with one tap.
Built for a small group. The Android app is still being tested.
The idea
The essentials, kept simple.
A small Android app with a straightforward way to connect and disconnect. Access is given personally by invitation.
Connect in one tap
Turn the connection on or off in the app. Android asks for your permission before the VPN starts.
Your key stays on your phone
The app creates your private key on the device and stores it in encrypted local storage. The server receives only your public key.
Getting started
Three steps to your first connection.
You need an Android phone, a beta APK, and an invitation from the person who gave you access.
- 01 / GET THE APP
Receive the APK
Your inviter shares the Android APK with you. There is no public app store release yet.
- 02 / ACTIVATE
Install and enter the code
Install the APK on Android 8 or newer, open TAVI, accept the data notice, and enter your one-time invitation code. It expires after 30 minutes.
- 03 / CONNECT
Tap Connect
Approve Android’s VPN request. The app shows when a fresh handshake with the server is available.
Have access to the project repository?
Open APK builds Open a successful “Beta Android APK” run in GitHub Actions, download the tavi-beta-debug artifact, unzip it, and install app-debug.apk. This is a testing build; public APK downloads are not available yet.
Your data
Clear by design.
TAVI is a closed beta. Here is the data the service uses to activate your device and maintain access.
What we don't log
Website addresses, browsing content, and DNS query history are not recorded by the TAVI service.
Short-lived records
Activation IP and brief connection metadata, including endpoint IP, handshake time, and traffic volume, are cleared after 30 days.
Access management
Device name and public key remain while access is active. If access is revoked, its record is removed after 30 days. Your private key stays on your phone.
Good to know
Before you begin.
Can I use TAVI on iPhone?
Not yet. This beta is for Android 8 and newer.
What if my connection drops?
Android can block traffic outside the VPN. Turn on “Always-on VPN” and “Block connections without VPN” for TAVI in Android settings if you want this protection.
Does TAVI make me anonymous?
No anonymity guarantee. It routes traffic through the private server; websites and other services can still identify you in other ways.
How do I stop using it?
Disconnect in the app. To revoke device access, ask the person who invited you.
