Privacy at a glance
Frequency, duration, ambience, and volume selections remain on the device. The app does not measure, collect, or infer EEG or other health signals.
Information collection
The app does not sell or share personal information. It does not display advertising, create user accounts, or transmit usage analytics to the developer.
On-device data
Settings and user-created content remain on your device unless you deliberately export or share them using an operating-system feature. Uninstalling the app may remove locally stored content.

If you deliberately export or share content, the security and retention practices of the destination you choose will apply.
