Did Purple Diary ask for something?

Pick the permission prompt you saw. We compare it with what Purple Diary's developer declared.

Tap a prompt to compare it with the label.
Not on the label

Location is not on Purple Diary'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.

Matches the label

Purple Diary lists User Content on its label, linked to you. Choose Limited Access and pick only the photos you want to share.

Not on the label

Contacts is not on Purple Diary'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

Purple Diary 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 Purple Diary'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 Purple Diary's label means for you

Purple Diary's label has 4 types under “Data Linked to You”, 1 type 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.

Purple Diary declares no tracking, which means the developer says it does not combine your data with other companies' data for advertising or sell it to data brokers. The data linked to you — user content, search history, contact info and identifiers — is still tied to your identity, typically through an account, and is covered by the developer's privacy policy and retention rules.

The items that deserve the most attention are user content. This is the content you actually care about. Where it is stored, who can read it and how it is backed up matters more than any other line on the label.

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. Purple Diary lists 5 data types, more than 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.

On your iPhone

Settings to check for Purple Diary

  1. 1

    Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. 2

    Photos

    Settings › Privacy & Security › Photos. Limited Access lets you pick exactly which pictures the app can see; Add Photos Only lets it save without reading your library.

  3. 3

    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.

  4. 4

    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.

  5. 5

    Notifications

    Settings › Notifications › Purple Diary › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

iOS 18 and later

Lock Purple Diary behind Face ID

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

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