Frequently asked questions
Does SlumberDoze work offline?
Yes. Every soundscape is bundled inside the app, so playback works in airplane mode. Network is never required.
How do I restore my PRO purchase?
Open Settings in the app and tap “Restore Purchases”. Make sure you are signed in with the same Apple ID used for the purchase.
Why can’t I hear anything with the screen off?
Sound keeps playing with the screen locked. If it stops, check that Background App Refresh and Low Power Mode are not restricting audio, and that the timer has not ended.
How do I delete my sleep data?
In the app, go to Settings › Clear All Records. Deleting the app also removes all local data from your device.
Is my night-time audio uploaded anywhere?
No. Sound analysis runs on your device, and audio clips stay in the app’s local sandbox. Nothing is uploaded to a server.
Does it work with Apple Health?
With your permission, SlumberDoze writes sleep sessions and mindful minutes to Apple Health. You can turn this off at any time in iOS Settings › Health.
