From registration to your first call
Sign in securely
The planned first version uses Google Sign-In and Cloudflare D1 authentication; no phone number is required.
Choose your display name
Use your actual name in any supported writing system. Multiple people can have the same name.
Receive a permanent JAT ID
The backend automatically assigns an immutable ID. A memorable unique username is optional, not mandatory.
Find or invite friends
Search for their JAT ID or optional username, or send an invite link and wait for acceptance.
Chat privately
The planned messaging engine stores conversation data behind account and membership checks.
Make a voice call
Open a contact, tap Call, and allow microphone access. Both parties need an active internet connection.
Handle interruptions
The planned calling engine will monitor connectivity and attempt a controlled reconnect where possible.
Manage privacy and safety
Block/report users, manage contact requests, and request account deletion.
Browser notification reality
If the site is open, we can play a ringtone subject to browser audio permissions. When closed, supported browser push notifications can alert the user, but continuous native-style ringing cannot be guaranteed.
What you need
A supported modern browser, internet access, a microphone for calls, and permission for notifications if you wish to receive them.
