Maps4Watch privacy policy

Last updated: 7 November 2026

Maps4Watch is a live map with your position for Huawei watches (GT 4 and newer, GT Runner 2, Watch FIT 3 and FIT 4). It has two parts: a watch app from Huawei AppGallery and an Android companion app from Google Play. This policy explains what the apps do with your data. In short: your location stays between your phone and your watch, and the only thing the apps download is map data.

Maps4Watch has no account and no sign-in. It shows no ads, and it uses no analytics and no crash reporting service.

Map data

The watch asks the phone for the map pieces (map tiles) around where it is, by tile key. The phone downloads those tiles from our map file host and sends them to the watch. The host is Cloudflare R2, at maps4watch-tiles.defoai.com, and the map data comes from OpenStreetMap.

  • A tile request contains only the tile's coordinates and standard internet connection data, such as your IP address, as for any download. It carries no user or device identifier.
  • We do not log, store or analyse these requests ourselves.
  • Cloudflare, as our hosting provider, may process connection data briefly to deliver and protect the service.

Your location

  • The watch uses its own GPS.
  • Phone location: while the watch has no GPS fix, for example indoors, and only while the app is in use, the phone passes its own location to the watch. It goes only to the watch, over Huawei's Wear Engine connection. You can turn this off in the phone app.
  • Offline areas: when you save an offline area, the phone app uses its location to centre the area on where you are. The location is used on the phone only.
  • Your location is never sent to us or to anyone else.
  • The app does not use your location in the background.

What stays on your phone and watch

  • Offline areas: areas you save are kept on your phone and your watch only.
  • Place search: place search runs on the phone.
  • Diagnostics: the phone app can build a diagnostics report. It contains no locations. It stays on the phone unless you share it yourself, for example by email to our support.

Huawei and the app stores

The connection between phone and watch uses Huawei Health and Huawei's Wear Engine, and HMS Core on phones not made by Huawei. Their processing is governed by Huawei's privacy policy. Installing the apps from Google Play or Huawei AppGallery is governed by those stores' own terms.

Android permissions

  • Location (precise and approximate): to give the watch a position when it has no GPS fix, and to centre an offline area on where you are, only while the app is in use.
  • Bluetooth connect and connected-device foreground service: to keep the link to the watch while you use it.
  • Notifications: to show the small "Ready for your watch" notification.
  • Network: to download map tiles.
  • Start at boot and battery-optimisation exemption: so the phone is ready when you open the watch app.

Children

Maps4Watch is not directed at children under 13.
