Privacy Policy

Last updated: April 2026

            The short version: Nothing leaves your device. We don't collect, store, or share any of your personal data.
        

Starr AI is a private AI assistant that runs entirely on your iPhone. All conversations are processed using on-device models — nothing is sent to any server.

Sun Light tracks your natural sunlight exposure on Apple Watch. It accesses your Time in Daylight data from Apple HealthKit and uses your device location to calculate local sunrise and sunset times. All of this stays on your device.

Data sharing

We do not share, sell, or transmit your personal data to anyone. Period.

Between your devices

Communication between your iPhone and Apple Watch uses Apple's built-in encrypted systems. Nothing is routed through external servers.

Children's privacy
