No account. Runs on your phone.

Jovii needs no sign-in, and your hardware readings are worked out on the device. It contains ads, and network tools such as ping and DNS tests contact public servers when you run them. Battery health is a software estimate, not a hardware reading. The privacy policy has the details.
