Privacy
Nothing REM reads about you leaves your devices.
No account. No server. No sync. The heart rate REM reads on your Watch is used for that half
hour and discarded; the sleep it reads on your phone is read, never written and never sent.
There is no export button because there is nothing anywhere to export.
REM's App Store privacy label is Data Not Collected — the strongest
one Apple offers, and the only one that would be true.
Privacy Policy
Last updated: 25 August 2026
REM is a sleep alarm for iPhone and Apple Watch. It has no account system, no servers of its
own, and no analytics. This policy describes everything it does with information.
What REM collects
Nothing. REM does not collect, transmit, sell or share personal information. No data is sent
to the developer or to any third party, and there is no third-party SDK in the app.
What REM reads on your device
- Apple Health — sleep (iPhone). With your permission, REM reads the sleep
your Apple Watch or iPhone has already recorded: when you fell asleep, when you woke, and the
Deep, Core and REM stages between. It is used to draw the Stats screen and to work out how
long you usually take to fall asleep. Read-only; REM never writes to Apple Health.
- Apple Health — heart rate (Apple Watch). With your permission, and only
during the thirty minutes before an alarm, REM reads the heart-rate samples your Watch takes
anyway, to tell lighter sleep from deep sleep. The readings are held in memory for that window
and discarded.
- Motion (Apple Watch). During the same thirty minutes, REM reads wrist
movement from the accelerometer and gyroscope to notice when you are stirring, and to notice
when the Watch is not being worn. Movement is never stored.
- Your alarms and settings. Alarm times, repeat days, nap lengths, your
name if you enter one, and your preferences are stored on your device and in the shared
container the app's widgets read. They are not backed up to any service by REM.
What leaves your phone
Between your iPhone and your Apple Watch, REM exchanges the details of your upcoming alarm —
its time, whether it is enabled, the vibration you chose — using Apple's own device-to-device
connection. That traffic goes between your two devices and nowhere else. Nothing else leaves
your phone at all.
Permissions REM asks for
- Alarms. Required for REM to set alarms that ring through Silent Mode and
a Focus. Without it, nothing you set will go off.
- Apple Health. Optional. Declining it turns off the Stats screen, and
leaves the smart wake running on movement alone.
- Motion. Optional, on the Watch. Declining it turns off the smart wake;
alarms still ring at the time you set.
- Notifications. Optional. Used for the bedtime and charge-your-Watch
reminders, and to tell you how much earlier the Watch woke you.
Every one of these can be revoked at any time in the Settings app. REM keeps working with
each of them off, minus the feature it powers.
Children
REM is not directed at children under 13 and collects no information from anyone.
Changes
If this policy changes, the new version will be posted here with a new date. Since REM
collects nothing, any change would be about what it reads on your device — and that would also
be visible in the permission text the system shows you.
