Nacre collects some data but says none of it is linked to your identity, and none is used for tracking.
Did Nacre ask for something?
Pick the permission prompt you saw. We compare it with what Nacre's developer declared.
Nacre lists Location on its label. Choose While Using and turn off Precise Location if the feature works without it.
User Content is not on Nacre'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 Nacre'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.
Nacre 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 Nacre'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 Nacre collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| LocationSensitiveNot linked to you | Where your phone is, either precisely (street level) or approximately (city or area). | Settings › Privacy & Security › Location Services: choose Never or While Using, and turn off Precise Location if the app does not need it. |
| Contact InfoNot linked to you | Your name, email address, phone number or postal address. | Use Sign in with Apple with Hide My Email where offered, and check the app's account and marketing preferences. |
What Nacre's label means for you
Nacre's label has 2 types under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.
Every type on Nacre's label is in the “not linked” section, so the developer says the data is stripped of anything that identifies you before it is used. That is typical of anonymous analytics and crash reporting. Not linked is still collected: the data leaves your phone.
The items that deserve the most attention are location. Location history reveals home, work and routines. Precise location deserves the most scrutiny.
Journals collect your private thoughts, moods and often your location and photos. A lock screen inside the app is not the same as encryption of the synced entries. Check whether entries sync to the developer's server and whether that sync is end-to-end encrypted; export your journal regularly.
Among the 173 journal & diary apps in our snapshot with a label, 32% declare tracking, 54% collect data linked to you and 21% say they collect nothing. Nacre lists 2 data types, about the same as the average of 2.9 for this group.
Lifestyle apps cover family, home and personal organisation, and often combine location, contacts and photos in one place.
Settings to check for Nacre
- 1
Location
Settings › Privacy & Security › Location Services › Nacre. Choose While Using or Never, and switch off Precise Location if a city-level answer is enough.
- 2
Sign-in
When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.
- 3
Lock the app
On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.
- 4
Notifications
Settings › Notifications › Nacre › Show Previews: When Unlocked keeps message and account details off the Lock Screen.
Does Nacre track you?
There is no “Data Used to Track You” section on Nacre's label.
Lock Nacre behind Face ID
- Find Nacre 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. Nacre now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Nacre 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 Nacre 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.
The question to ask Nacre's developer: Can anyone at the company read my entries?
