Windshield HUD – Privacy Policy

Last updated: November 9, 2026

Windshield HUD ("the app") turns your iPhone into a head-up display. We built it to work without accounts, ads or tracking. This policy explains what data the app uses and where it goes.

What we collect

Nothing. The developer does not run servers for the app, has no user accounts, and receives no data from it. The app contains no analytics, advertising or tracking code.

Location

The app uses your location, only while it is open, to show your speed, the speed limit and turn-by-turn directions. Your location stays on your iPhone, except as described below to fetch maps and routes.

Services the app contacts

• Apple Maps (search, routes and the map): your search text, start and destination and the map area on screen are sent to Apple under Apple's privacy policy.
• OpenStreetMap data via the Overpass API (speed limits, lanes and speed cameras): the app requests map data for roughly 1 km areas around your route or position. These requests reveal the area to the server operator (e.g. overpass-api.de, overpass.openstreetmap.fr), as any web request reveals your IP address. They contain no account or device identifier.
• OpenFreeMap (street outlines): map tiles for the area around you are downloaded the same way.

Downloaded map data is cached on your iPhone and deleted after 30 days.

Purchases

HUD Pro is sold through the App Store. Apple processes the payment; the developer never sees your payment details or Apple Account.

Settings and recent places

Your settings and your last few destinations are stored only on your iPhone. Deleting the app deletes them.

Children

The app is not directed at children and collects no personal information from anyone.

Changes and contact

If this policy changes, the new version will be posted on this page. Questions: open an issue at github.com/ReyML/windshield-hud.
