Privacy policy
Last updated October 4, 2026
Sleep Static does not collect, store on a server, sell or share personal data.
In the app
- No account. There is no sign-in and no user profile.
- On your device only. Your saved mixes, your last-used mix and your settings (language, appearance) are stored on the iPhone. They are not uploaded or synced. Deleting the app removes them.
- No analytics, advertising or tracking. The app contains no third-party SDKs and does not use the advertising identifier.
- No network needed. Every sound is generated or bundled with the app; nothing is streamed.
- No microphone, location, contacts or photos. The app asks for none of these permissions.
The coffee tip
The optional “Buy me a coffee” tip is processed by Apple through the App Store. We never receive your payment details, and the app does not keep a purchase history.
On this website
- No analytics, ads, third-party scripts or tracking cookies.
- If you send a message with the form, we store what you typed, whether it is an idea or a problem, an email address only if you give one, the page language and the time. We do not store your IP address or browser details.
- Sending a message sets one cookie with a random code, so this browser can show you your own messages. It is set only after you send something, and clearing your cookies removes it.
Children
Sleep Static is suitable for everyone and collects nothing from anyone, children included.
Changes
If this policy changes, the new version is published on this page with a new date.
