Google Play Data Safety: How to Read It for a Health App

How do you read Google Play's Data safety section for a health app? On the app's Play Store page, find Data safety and tap See details. You will see three main parts: Data shared, Data collected and Security practices. For a health app, check what is listed under Health and fitness, what each item is used for, whether it is optional, and whether you can request deletion.

Then keep two things in mind. The developer writes this section, and Google says it cannot determine how each developer handles data. And words like "shared" have narrower meanings than everyday English. This guide is about Google Play only; iPhone users can read our guide to Apple's App Privacy labels.

Where do you find the Data safety section?

Open the Google Play Store, search for the app and tap it. Scroll to the Data safety heading, which shows a short summary. Tap See details for the full list of data types, purposes and security practices. The section appears for apps distributed through Google Play on Android 5 and up.

What does "Data shared" mean?

This is the part people misread most. In Google's definition, "sharing" means transferring user data to a third party. But several transfers do not count as sharing, including:

• Transfers to service providers that process data on the developer's behalf (hosting, payments, many AI processors).
• Transfers for legal reasons.
• Transfers you start yourself, or that happen after a prominent disclosure and your consent.
• Data that is fully anonymized.

So "No data shared with third parties" can be accurate even if your health logs sit on a cloud provider's servers or pass through an outside AI service working for the app. It is not the same as "nobody else ever touches your data." The privacy policy is where companies should name those service providers; our privacy policy checklist shows what to look for.

What does "Data collected" mean?

"Collected" means data sent off your phone, including by code libraries built into the app. Two things are excluded from the store listing:

• Data processed only on your device.
• Data that is end-to-end encrypted so the developer cannot read it.

Data processed "ephemerally," meaning held only in memory for a real-time request, still has to be reported to Google in the developer's form but is not shown in the store listing.

Under Data collected, each data type has purposes and, sometimes, the word Optional. Google lets developers mark a type optional only if every user, on every device and in every region, can avoid providing it.

Which data types should you look for in a GLP-1 app?

Play category	Includes	What to check
Health and fitness	Health info (e.g. symptoms, medical records), Fitness info (e.g. exercise)	Purposes: app functionality is expected; advertising or marketing is worth questioning
Photos and videos	Photos, Videos	Is it optional? Is it only for app functionality?
Personal info	Name, email address, user IDs	Normal for an account; look at purposes
Device or other IDs	Device identifiers	Listed for advertising or marketing?
App activity	App interactions, other user-generated content	Analytics vs advertising
Location	Approximate or precise	Does a GLP-1 tracker need it, and for what?
Financial info	Purchase history	Expected if the app sells subscriptions

A good habit: for each health-related item, ask "Would I expect this purpose from what the app does?" A weight log used for app functionality makes sense. Health info used for advertising or marketing is a reason to read the privacy policy before you sign up.

What do the Security practices mean?

You may see statements like:

• Data is encrypted in transit. The developer says data moving between your phone and their servers is protected (for example with HTTPS). It says nothing about how data is stored.
• A way to request data deletion. The developer says you can ask for your data to be deleted. Google does not prescribe the mechanism; it could be an in-app button, a form or an email address. Developers can also qualify by automatically deleting or anonymizing data within 90 days.
• Independent security review. An optional badge for apps checked by an authorized lab against a mobile security standard. Google points out this review checks security practices; it does not verify that the Data safety answers are accurate or complete.

Separately, Google Play requires apps that let you create an account to offer account deletion both inside the app and through a web link that works even after you uninstall. Our guide to exporting and deleting GLP-1 tracking data covers what to test before you rely on it.

What can the Data safety section not tell you?

• Who the service providers are. No company names appear.
• How long data is kept. Retention is in the privacy policy.
• Whether AI providers train on your data. Again, the policy.
• Version or region differences. Google says one Data safety section covers all versions of an app on Play, though practices may vary by use, region or age.
• What permissions the app requests. Google notes that the permissions list is based on the app's technical behavior and can differ from the Data safety section. You can check permissions on your phone at Settings → Apps → [app] → Permissions.

A quick Data safety check for health apps

1. Tap See details. Do not stop at the summary.
2. Under Data collected, find Health and fitness. Note every purpose listed.
3. Look for advertising or marketing next to anything health-related or next to device IDs.
4. Check whether Photos are marked optional.
5. Under Security practices, look for encryption in transit and a deletion option.
6. Open the privacy policy and find the names of service providers and AI processors.

If something does not add up, email the developer before you start logging. A clear answer is a good sign; silence is information too.

Common questions

Does Google check Data safety answers?

Google reviews submissions but says it cannot determine on its own how developers handle data, and that developers alone are responsible for complete and accurate declarations. If misrepresentation is found, Google can require fixes or take enforcement action.

Why does an app say "No data shared" when it uses cloud servers?

Because transfers to service providers working on the developer's behalf are not counted as sharing under Google's definitions.

Is "Optional" next to a data type a good sign?

It means every user can avoid providing that data. It is a good sign for sensitive items like photos, as long as the app still works for your main needs without them.

Should I trust an app with a perfect-looking Data safety section?

Use it as a first filter, then read the privacy policy. Both are written by the developer, so they should match each other.
