The developer states that no data is collected from this app.
On the label, yes. SleepMatic's developer reports that it collects no data, which puts it among the 3% of health trackers we checked with a "Data Not Collected" label. That is a self-declared statement, not an audit, and it does not cover data processed only on your device.

SleepMatic's developer states that the app does not collect any data from this app.
Did SleepMatic ask for something?
Pick the permission prompt you saw. We compare it with what SleepMatic's developer declared.
Location is not on SleepMatic's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
User Content is not on SleepMatic's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
Contacts is not on SleepMatic's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
SleepMatic declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.
Health & Fitness is not on SleepMatic's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
A permission is what the app can reach on your iPhone; the label is what the developer says leaves it. They answer different questions.
What SleepMatic's label means for you
“Data Not Collected” is the cleanest result a label can show. It means the developer states that no data leaves your iPhone in a way the developer or its partners can access for longer than needed to handle a request. Data processed only on your device does not count as collected, so SleepMatic can still read files or photos you open in it.
The statement is the developer's own. Apple reviews apps but does not audit every label, and analytics or crash-reporting libraries added later can make a label out of date. If SleepMatic asks you to create an account, upload files or allow tracking, that would not match a no-collection label — and is worth noticing.
Health trackers collect symptoms, vitals and habits. In the US, most consumer health apps are not covered by HIPAA, so the privacy policy is your main protection. Grant HealthKit categories one by one in the Health app, and avoid connecting categories the app does not need.
Among the 180 health trackers in our snapshot with a label, 59% declare tracking, 84% collect data linked to you and 3% say they collect nothing. SleepMatic lists 0 data types, fewer than the average of 5.1 for this group.
Health and fitness apps can read Apple Health data only for categories you approve, one by one. What they collect themselves is shown on the label.

Does SleepMatic track you?
There is no “Data Used to Track You” section on SleepMatic's label.
Lock SleepMatic behind Face ID
- Find SleepMatic on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. SleepMatic now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not SleepMatic has a passcode of its own. It does not change what the app sends to its developer.

What the label cannot tell you
- A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what SleepMatic sends.
- It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
- Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
- Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
- Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
