Reading the label

What Simple Diary - Daily Journal's label means for you

Simple Diary - Daily Journal's label has 2 types under “Data Used to Track You”, 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.

Tracking is the declaration that most separates apps. It means identifiers, usage data from Simple Diary - Daily Journal can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.

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. Simple Diary - Daily Journal lists 4 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.

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 Simple Diary - Daily 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.
