Head Booster ("the app") is published by Websolve (contact:
biuro@websolve.pl). This policy explains how the app handles data.
Data collection
The app itself does not collect, store or share any personal data. There
is no account, no registration and no analytics SDK.
Advertising
The app shows a small banner at the bottom of the main screen. Two
sources are used:
Our own promotions — fetched from our server
(websolve.pl). This is a standard web request; we do not store any
information about you. Impression and click counters are kept only
locally on your device.
Google AdMob — Google's advertising SDK, which may
collect your device's Advertising ID, ad interaction data,
diagnostics and approximate location (from IP) to serve and measure
ads. Details:
How Google uses data. You can reset or delete your Advertising ID
in Android settings (Settings → Privacy → Ads).
Data stored on your device
The app saves only its own settings locally on your device: the chosen
boost level, the chosen app language and whether the hearing-safety warning
has been shown. This data never leaves your device and is removed when you
uninstall the app.
Permissions
Modify audio settings – required to change the media
volume and apply the loudness boost.
Foreground service / notifications – required to keep
the boost running while you use other apps and to show a persistent
notification with a stop button.
Children
The app does not knowingly collect any data from anyone, including
children.
Changes
If this policy changes (for example if advertising is added in a future
version), the updated policy will be published at this address before the
change takes effect.
