Location is not on Cardi Mate'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.

Expected — and you can decline

Cardi Mate declares data used to track you, so expect the “Allow to track?” prompt. Tap Ask App Not to Track; the app must keep working without it.

Not on the label

Health & Fitness is not on Cardi Mate'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 Cardi Mate's label means for you

Cardi Mate'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 purchases, identifiers from Cardi Mate 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.

Health trackers collect symptoms, vitals and habits. In the US, most consumer health apps are not covered by HIPAA, so the privacy policy is your main protection. Grant HealthKit categories one by one in the Health app, and avoid connecting categories the app does not need.

Among the 180 health trackers in our snapshot with a label, 59% declare tracking, 84% collect data linked to you and 3% say they collect nothing. Cardi Mate lists 4 data types, fewer than the average of 5.1 for this group.

Health and fitness apps can read Apple Health data only for categories you approve, one by one. What they collect themselves is shown on the label.

On your iPhone

Settings to check for Cardi Mate

  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

    Health

    Health app › your profile picture › Apps › Cardi Mate. Turn categories on one at a time; the app cannot tell which ones you declined.

  3. 3

    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.

  4. 4

    Notifications

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

Cross-app tracking

Does Cardi Mate track you?

iOS 18 and later

Lock Cardi Mate behind Face ID

  1. Find Cardi Mate 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. Cardi Mate now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Cardi Mate 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 Cardi Mate 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.
