None declared
It depends on how you feel about tracking: My Water declares data used to track you. None of it falls in Apple's most sensitive categories (health, financial, location, contacts or your own content). In total the label lists 4 data types; 59% of health trackers we checked declare tracking.

Built only from the developer's App Store label. It describes disclosure, not tested behaviour.
My Water's developer reports using purchases, identifiers, usage data, diagnostics to track you across other companies' apps and websites.
Did My Water ask for something?
Pick the permission prompt you saw. We compare it with what My Water's developer declared.
Location is not on My Water'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.
User Content is not on My Water'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.
Contacts is not on My Water'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.
My Water 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.
Health & Fitness is not on My Water'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.
What My Water collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| PurchasesUsed to track youNot linked to you | What you have bought or tend to buy. | Review in-app marketing settings; subscriptions are listed in Settings › [your name] › Subscriptions. |
| IdentifiersUsed to track youNot linked to you | An account ID, screen name, customer number or a device-level ID such as the advertising identifier. | Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted. |
| Usage DataUsed to track youNot linked to you | What you tap, open and view inside the app, plus which ads you have seen. | There is no single iOS switch. Look for an analytics or personalised-ads toggle in the app's own settings. |
| DiagnosticsUsed to track youNot linked to you | Crash logs, launch times, hang rates and energy use. | Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate. |
What My Water's label means for you
My Water's label has 4 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, usage data, diagnostics from My Water 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. My Water 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.

Does My Water track you?
Purchases, identifiers, usage data and diagnostics. Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker.
Lock My Water behind Face ID
- Find My Water on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. My Water now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not My Water has a passcode of its own. It does not change what the app sends to its developer.

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 My Water 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.
