Privacy Policy for Optokinetic Drum
Last updated: June 2026
Optokinetic Drum ("the app") does not collect, store, or transmit any
personal data to us or to any third party. All settings and preferences
(pattern, speed, density, color, Pro unlock status) are stored locally
on your device using browser local storage and never leave your device.
In-app purchases: The one-time "Pro unlock" purchase is processed
entirely by Google Play Billing. We do not receive, see, or store any
payment, card, or billing information — that is handled exclusively by
Google under Google Play's own privacy policy.
The app does not contain advertising or third-party analytics SDKs.
This app is not directed at children and does not knowingly collect
any information from anyone, including children.
