Line by line

What Diabetes Tracker by MyNetDiary collects, explained

Data typeWhat it coversWhere to limit it

Reading the label

What Diabetes Tracker by MyNetDiary's label means for you

Diabetes Tracker by MyNetDiary's label has 5 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 Diabetes Tracker by MyNetDiary'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.

The items that deserve the most attention are health and fitness and user content. Health data is among the most sensitive data an app can hold, and US health-privacy law (HIPAA) does not cover most consumer apps.

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. Diabetes Tracker by MyNetDiary lists 5 data types, more than the average of 2.9 for this group.

Medical apps may hold the most sensitive data on your phone. Whether US health-privacy law applies depends on who runs the app, not on the App Store category.

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 Diabetes Tracker by MyNetDiary 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.
