Privacy policy

Last updated: 2026-10-15

This app (Hand Warmer) warms your phone to a temperature you choose. This policy explains what data stays where. In short: we collect no data.

What stays on your device

Your chosen target temperature, the free-time and emergency counters, whether you have seen the intro, and whether your subscription is active. These are stored only on your device and are never sent to us.

Sensors

On Android the app reads the battery temperature; on both platforms it reads the system's thermal state so it can slow down or stop before the device gets too hot. These readings are used on the spot and are not stored or shared.

What we don't collect

No account; your name or e-mail is never asked for. No analytics, advertising, tracking or third-party SDKs. No access to your location, contacts or photos. The app's own code does not connect to the internet.

Subscription

The subscription is handled by the App Store or Google Play through your own account. Payment details are processed by Apple or Google and are never passed to us. The app checks the subscription on the device; we run no server for it.

Deleting your data

Deleting the app deletes all of its data.

Age

The app is suitable for all ages. No personal data is collected from anyone of any age.

Changes and contact

If this policy changes, the updated version is published on this page. For questions, write to [email protected].
