Sleep Deep privacy policy
Sleep Deep plays sound through the night to help you fall asleep. This page explains plainly what the app does with information.
Who we are
Sleep Deep is published by Adam Young (“the developer”). Questions about this policy can be sent through the contact page.
What the app stores on your phone
To work, the app keeps a few things in its private storage on your device:
- your settings, such as how Stop works, the night arc you chose and volume levels;
- the mixes you saved and your recent mixes;
- your sleep journal: the nights you used the app, what played, how you said you slept, and anything you choose to write, such as your mood, a note, factors like caffeine or exercise, and dreams;
- if you link Health Connect (see below), the sleep and health data the app reads from it, kept with the journal.
This information stays on your device. The developer cannot see it. Uninstalling the app, or clearing its storage in Android settings, deletes it.
What the app does not collect
- No account, name, email address or phone number.
- No location, contacts, photos, microphone or camera data.
- Nothing from Health Connect unless you link it, and then only what you allow.
- No advertising identifier, and no ads.
- No usage analytics or crash reports in this version.
Permissions
- Foreground service (media playback): keeps sound playing with the screen off.
- Health Connect (optional, read only): sleep sessions and stages, and if you allow them heart rate, resting heart rate, heart rate variability, breathing rate, blood oxygen, steps and exercise. Older data than the last 30 days is read only if you allow “Import earlier nights”. Each is a separate choice in Health Connect’s own permission screen.
- Notifications: shows playback controls and any reminders you turn on. You can decline and still use the app.
Health Connect
Health Connect is Android’s place where watches, rings, phones and health apps keep health data. If you link it from the Journal, Sleep Deep reads:
- your sleep sessions and sleep stages;
- if you allow them: heart rate, resting heart rate, heart rate variability, breathing rate and blood oxygen during your sleep, and your steps and exercise for the day before.
Why: to show them in your journal beside the nights you used Sleep Deep, so you can see how a night went and what went with it. Sleep Deep only reads. It never writes anything to Health Connect.
Where it goes: what the app reads is stored in the app’s private storage on your phone, with your journal. It is not sent to the developer or to anyone else, not used for advertising, and not shared. The analysis that compares your nights runs on your phone.
Control: you can remove any or all access at any time in Health Connect settings, and the app stops reading. To delete what the app has already stored, clear Sleep Deep’s storage in Android settings or uninstall it.
Purchases
Sleep Deep Essentials is free. Sleep Deep Complete is an optional yearly subscription sold through Google Play. Google handles payment and billing under its own privacy policy; the app does not see your card or payment details. You can cancel any time in Google Play.
Sharing
We do not sell, rent or share your information, because the app does not collect it.
Children
Sleep Deep is intended for adults and is not directed at children under 18.
Health notice
Sleep Deep is for relaxation. It is not a medical device and does not diagnose, treat, cure or prevent any medical condition. For medical advice, talk to a healthcare professional.
Changes
The Health Connect section above was added on 4 October 2026. If a future version collects anything more, such as usage statistics, this page will be updated first to say exactly what is collected, why, and how to turn it off. The effective date above shows when this page last changed.
