Lazewalk is a step tracker for iPhone. This policy explains exactly what the app touches. In short: your step data never leaves your device. Lazewalk does show a banner ad, and that involves a third party — the details are below.
With your explicit permission, Lazewalk reads and writes one type of data through Apple's HealthKit framework:
Lazewalk requests no other health data type, no location, no contacts, no camera, no microphone, and no notifications.
Nowhere. Step data is read from and written to HealthKit on your device and stays there. Lazewalk has no backend and no user accounts, and it never transmits your step count, your history, or any other health information. Your health data is never uploaded, shared, sold, or used to target advertising.
Lazewalk displays one banner advertisement, served by Google AdMob (the Google Mobile Ads SDK). To deliver and measure those ads, Google receives standard technical information such as a device advertising identifier, your IP address, device type, and whether an ad was seen or tapped.
Two things are worth stating plainly:
Google's handling of this data is governed by its own policy: https://policies.google.com/privacy
You can limit ad personalisation system-wide in Settings › Privacy & Security › Tracking and Settings › Privacy & Security › Apple Advertising.
