None declared
On the label it is low-risk: Locked Notes° collects some data but says none of it is linked to you or used for tracking. None of it falls in Apple's most sensitive categories (health, financial, location, contacts or your own content). In total the label lists 4 data types; 25% of encrypted notes apps we checked declare tracking.

Locked Notes° collects some data but says none of it is linked to your identity, and none is used for tracking.
Did Locked Notes° ask for something?
Pick the permission prompt you saw. We compare it with what Locked Notes°'s developer declared.
Location is not on Locked Notes°'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 Locked Notes°'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 Locked Notes°'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.
Locked Notes° 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 Locked Notes°'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 Locked Notes° collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| PurchasesNot linked to you | What you have bought or tend to buy. | Review in-app marketing settings; subscriptions are listed in Settings › [your name] › Subscriptions. |
| IdentifiersNot linked to you | An account ID, screen name, customer number or a device-level ID such as the advertising identifier. | Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted. |
| Usage DataNot linked to you | What you tap, open and view inside the app, plus which ads you have seen. | There is no single iOS switch. Look for an analytics or personalised-ads toggle in the app's own settings. |
| DiagnosticsNot linked to you | Crash logs, launch times, hang rates and energy use. | Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate. |
What Locked Notes°'s label means for you
Locked Notes°'s label has 4 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 Locked Notes°'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.
None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.
Notes apps quietly collect some of your most personal writing. 'Encrypted' can mean encrypted in transit, at rest on the server, or end-to-end — only the last keeps the developer out. Find which kind of encryption the developer documents, and whether a lost password means lost notes.
Among the 146 encrypted notes apps in our snapshot with a label, 25% declare tracking, 40% collect data linked to you and 40% say they collect nothing. Locked Notes° lists 4 data types, more than the average of 1.8 for this group.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.

Does Locked Notes° track you? Full answer and how to stop it →
Lock Locked Notes° behind Face ID
- Find Locked Notes° 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. Locked Notes° now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Locked Notes° 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 Locked Notes° 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.
