Is Note Book App Safe?

Note Book App privacy label · by Primus Okorie · checked November 2026

  • Collects no data
App Privacy label Developer-reported · checked November 1, 2026
Data Not Collected

The developer states that no data is collected from this app.

Short answer

On the label, yes. Note Book App's developer reports that it collects no data, which puts it among the 40% of encrypted notes apps 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.

Not on the label

Location is not on Note Book App'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 Note Book App'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 Note Book App'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.

Not declared on the label

Note Book App declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.

Not on the label

Health & Fitness is not on Note Book App'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.

Reading the label

What Note Book App'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 Note Book App 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reviews apps but does not audit every label, and analytics or crash-reporting libraries added later can make a label out of date.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 Note Book App asks you to create an account, upload files or allow tracking, that would not match a no-collection label — and is worth noticing.

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. Note Book App lists 0 data types, fewer than the average of 1.8 for this group.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

On your iPhone

iOS 18 and later

Lock Note Book App behind Face ID

  1. Find Note Book App on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. Note Book App now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Note Book App has a passcode of its own. It does not change what the app sends to its developer.

Read with care

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 Note Book App 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.

Quick quiz

True or false?

  1. Q1Note Book App's privacy label says it uses data to track you.
    Right.
    Not quite.

    False: there is no Data Used to Track You section on Note Book App's label.

  2. Q2Apple tests every app to confirm its privacy label is accurate.
    Right.
    Not quite.

    Labels are self-reported by developers. Apple can reject or remove apps that misrepresent practices, but it does not audit each label.

  3. Q3An app with a “Data Not Collected” label cannot read any of your photos.
    Right.
    Not quite.

    It can read photos you give it access to. Processing on your device is not collection; only data sent off the phone counts.

  4. Q4Data “Not Linked to You” is never sent off your iPhone.
    Right.
    Not quite.

    It is collected and sent; the developer says it is de-identified rather than tied to your account or device.

  5. Q5Tapping “Ask App Not to Track” can stop an app from working.
    Right.
    Not quite.

    Apple's rules require apps to work the same whether or not you allow tracking.
