Privacy notice

Last updated: 9 November 2026

Lull & Moss is designed to work without an account, advertising or analytics in the app itself. This notice describes the Lull & Moss app and its website hosting.

Cookies and device storage

The Lull & Moss app does not set or use cookies. It uses your browser’s local storage to remember your selected sounds and volume settings. Your browser also stores a service-worker cache of the app’s files so it can work offline after an initial visit. These are different from cookies, but they are still stored on your device.

These settings stay on your device until you clear the site’s browser storage. Clearing site data removes the saved mix and cached files. The next visit may download the app again.

Website hosting

This website is intended to be hosted using Cloudflare. Hosting services may process network information, such as your IP address, to deliver and secure the website. See Cloudflare’s privacy policy for information about its services. The app itself does not send your sound choices or volume settings to a server. The operator must review this notice against the actual hosting configuration before public launch.

Sound and connections

Noise is generated on your device. Recorded nature sounds are hosted with the app and downloaded when selected. Lull & Moss does not use your microphone, request location, or send recordings to a server. Your browser requests the app’s files from the hosting service when needed.

Optional donations

If you choose to follow the Buy Me a Coffee link, you will leave Lull & Moss and visit a separate service. Buy Me a Coffee handles any information you choose to provide there under its own privacy policy. Lull & Moss does not receive your payment details through this app.

Future releases

Hosting, privacy contacts and data practices may change before a public or mobile release. This notice must be reviewed and updated for the actual operator and services used before release.

About Lull & Moss

Lull & Moss is a free, open-source sound mixer. Noise sounds are generated on your device. The sound library also includes real recordings, which are downloaded when selected and can repeat. Your selections and volume settings are stored locally.

For reliable overnight playback, keep this page open. Browsers and mobile operating systems may pause audio in the background. Native mobile builds need additional background-audio work and device testing.
