LimitAlert Privacy Policy

Last updated 25 October 2026 (HERE lookups added)

LimitAlert tells you the speed limit of the road you're on and warns you when you go over it. It is designed to work without collecting personal data: there's no account, no advertising, no analytics and no tracking.

Your location

LimitAlert uses your iPhone's location to measure your speed and to work out which road you're on. This happens on your iPhone. Your location is not sent to us.

If you turn on Detect drives in the background, LimitAlert asks for location access Always, so iOS can wake it when you start moving and a journey can start without opening the app. You can turn this off in LimitAlert's settings, or change location access at any time in Settings › Privacy & Security › Location Services.

Map data downloads

To know the speed limits, the app downloads road data for the area around you, in squares of about 1.5 km:

In the UK, from our map storage on Microsoft Azure. Each request names a map square, which reveals the approximate area you're in. We don't log, keep or analyse these requests.
Outside the UK, from the public Overpass API, a community-run OpenStreetMap service, which receives the map square's coordinates. Its operators' own policies apply.

When the road you're driving on has no speed limit in OpenStreetMap, the app asks HERE Technologies for it, sending your current position and direction of travel (and nothing that identifies you). The answer is saved on your iPhone for up to 30 days, so each road is looked up at most about once a month; it's never uploaded. Deleting saved map data in the app (or the app) removes it. HERE's own privacy policy applies to those requests.

As with any internet request, the servers see your IP address while they answer the request.

Trips

When trip history is on, finished journeys (start and end places, route, speeds, time over the limit) are saved on your iPhone only. They are never uploaded. You can delete trips in the app, turn trip history off, or delete the app to remove them all. Your Home location, if you set one, is also stored only on your iPhone.

To show place names for trips and Home, the app asks Apple's mapping service for the address of those points. Apple's privacy policy applies to that service.

Subscriptions

Subscriptions are bought, renewed and cancelled through your Apple ID. Apple handles payment; we never see your payment details. The app only checks with Apple whether a subscription is active.

Other permissions

Microphone: LimitAlert never records or listens. iOS asks for microphone access because alerts play through your car's speakers like a phone call (or are forced to the iPhone speaker), which uses the same audio mode as calls. You can choose plain Bluetooth audio in Settings instead.
Lock Screen and Dynamic Island: your speed and the limit are shown by iOS on your device.
Shortcuts: the Start and Stop LimitAlert actions run only when you set them up.

Children

LimitAlert is a driving aid and isn't directed at children. It collects no personal data from anyone.

Changes

If this policy changes, the new version will be published here with a new date.
