Effective date: 02/08/2026
Stillness ("the app") is developed by an independent developer, contactable at diego.herrera.1@gmail.com. This policy explains what data the app collects and how it is used.
Stillness does not create accounts, does not use analytics, does not show advertising, and does not collect or transmit any personal data to us or to any third party.
Your choices within the app — which mood or breathing pattern you select, whether you've turned on the autism-adapted mode, your session count, and similar preferences — are stored only in your device's local storage. None of it ever leaves your device.
Stillness offers optional one-time tips through Google Play's billing system. When you choose to leave a tip, the transaction is handled entirely by Google Play and is governed by Google's Privacy Policy and Google Play's own terms. We never receive, see, or store your payment details.
The app requests no special device permissions. It uses standard internet access only at the moment you choose to leave a tip, so Google Play Billing can process it.
Stillness does not knowingly collect data from anyone, including children, because it does not collect data from anyone at all.
If this policy changes, the updated version will be posted at this same address with a new effective date.
