Deep Slumber — Sleep Sounds & Mixer
Deep Slumber ("we", "our", "us") is a sleep sounds application developed by Ryan Roberts. This Privacy Policy explains how we handle your information when you use the Deep Slumber app.
We do not collect any personal information. No name, email address, account, or profile is required to use Deep Slumber.
The following data is stored exclusively on your device and never transmitted to us or any third party:
Deep Slumber does not access your camera, microphone, or location.
Deep Slumber is fully offline. All sounds — including synthesized noise, binaural beats, solfeggio frequencies, and downloaded nature sounds — are stored locally on your device. No network requests are made during normal use of the app.
Internet access is only used for the one-time in-app purchase flow, which is handled entirely by Google Play (Android) or the Apple App Store (iOS).
Deep Slumber offers an optional one-time premium upgrade ($1.99) to unlock the full sound library.
We do not store, process, or have access to your payment information. We receive only a confirmation of whether a purchase was completed.
All app data is stored locally on your device using standard device storage mechanisms. We do not maintain any servers, databases, or cloud services that hold your data.
If you uninstall the app or clear app data, all locally stored preferences and mixes will be deleted. This data cannot be recovered by us because we do not have a copy of it.
Deep Slumber is appropriate for all ages. We do not knowingly collect personal information from anyone, including children under 13. Because we collect no personal data at all, there is no risk to children's privacy.
Because we collect no personal information, there is no data for us to access, provide, modify, or delete on your behalf. You have full control over all data on your device:
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. Continued use of the app after changes constitutes acceptance of the updated policy.
