Proof of concept — demo environment, not production. No SLA, no emergency calling (no 911/112), data may be reset without notice. Calls will drop after ~50s as the app is in testing mode.

T9 nicknames

Dial digits = T9 of the target's nickname. No phone numbers to remember.

In a world that chases features and tracks everything, we went the other way.

No numbers · No contacts · No history · No messages · No recording · No tracking · No call logs.

Just the call.
