Short answer

On the label it is low-risk: Diary Private Journal 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 2 data types; 32% of journal & diary apps we checked declare tracking.

Health & Fitness is not on Diary Private Journal'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 Diary Private Journal's label means for you

Diary Private Journal'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 Diary Private Journal'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.

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. Diary Private Journal 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.

iOS 18 and later

Lock Diary Private Journal behind Face ID

  1. Find Diary Private Journal 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. Diary Private Journal now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Diary Private Journal 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 Diary Private Journal 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.
