Brown Noise is made by Solidary Solutions AB, Sweden. This page describes what the app does with data. The short version: everything stays on your phone.
Nothing, by us. The app has no account, no sign-up, and no analytics run by us. All sounds are generated files bundled with the app; nothing is streamed. Your volume and timer settings are stored only on your phone. The app works fully offline and the banner ad is never shown while sound is playing.
Advertising. The free version shows one banner ad served by Google AdMob. AdMob may process device information (such as advertising ID and IP address) to serve and measure ads, as in any ad-supported app. In the EU/EEA and UK you will be asked for consent first, and you can choose non-personalized ads. See Google's privacy policy. If you purchase "Remove ads", no ads are shown.
Purchases. The "Remove ads" purchase is handled entirely by Google Play. We receive no payment details.
We run no servers for this app, so there is nothing for us to retain, sell, or share. The only third party involved is Google (AdMob for ads, Google Play for purchases), under their own policies.
The app is not directed at children.
