Your privacy
comes first
ReadyForCall is built around a strict zero-data principle. Every diagnostic runs entirely inside your browser sandbox — no server ever sees your camera, microphone, or network probe.
No recordings uploaded
Raw media streams are processed in-memory and never persisted.
Everything runs locally
Powered by WebRTC and Web Audio APIs in your own browser.
No account required
Anonymous usage. No sign-up, no tracking, no email.
Camera & mic stay private
We never see your video or audio data — your device, your data.
