Privacy Policy
Dart Weather for Auto · updated October 16, 2026 · the Google Play edition (the car, the phone and Android Auto), by Dart Technologies. The Galaxy Store edition has its own policy.
No accounts and no ads: the app never collects your name, email, phone number or advertising ID.
Location
With your permission the app uses your location for local weather. Weather requests round coordinates to two decimals (about 1 km); routing and destination search can send exact route points and your search text; map tiles reveal the area viewed; aviation alerts send a box of about 10 miles; and in the car the system’s geocoder (Google’s, on cars with Google built-in) looks up your country. Some alert feeds receive no coordinates, filtered on the device instead. Requests use HTTPS, providers see your IP address, and your location is never sold or used for ads.
| Provider | Used for |
|---|---|
| Pirate Weather, Open-Meteo, MET Norway, NOAA climate normals (US) | Conditions, forecast, air quality, normals |
| Your region’s weather authority (NWS/NOAA, ECCC, JMA, MeteoAlarm, WMO SWIC members and more) | Severe-weather alerts |
| LibreWXR, RainViewer, IEM; Geoapify with TomTom fallback (phone, Android Auto) or Mapbox (car) | Radar, satellite, base map — coarse tile coordinates |
| Google Pollen, OSRM, OpenStreetMap; backups OpenWeatherMap, Geoapify, LocationIQ | Pollen, routing, geocoding — backups only when a primary fails |
Notifications
The car app shows severe-weather alerts and the optional daily summary as notifications. From version 1.37.30 it can ask for permission to do so on Android 13 and later. That request is off when 1.37.30 is released, and we may turn it on later for some or all cars, so you may never see it. When it is on, the car app may ask once — only while the car is parked and after weather is on screen — and, while notifications are still off, at most once more, no sooner than 14 days later. Declining keeps the app working without notifications; you can change it at any time in the system settings. Whether the request was shown and how you answered is recorded with the usage analytics below. On the phone, a notification shows while the app is on an Android Auto car screen.
Analytics and crash reports
Release builds send pseudonymous crash reports (Firebase Crashlytics) and usage analytics (Firebase Analytics and PostHog), copied into our Google BigQuery warehouse, to keep the app reliable. They carry random installation IDs (the car app shares one between Firebase and PostHog); app, OS, firmware and system-app versions; the device model and cellular network type; which features are used and how reliably weather loads (failures and their causes, timings, a new install’s first launches, why the phone’s minute rain card was not shown, and, in categories only, whether a route planned on the phone reached Android Auto); on the phone, the size class and fold posture of the app’s window (also kept with crash reports); how the app was installed; whether it is our own test traffic; and the general sky condition shown (one of 13 categories, such as rain or clear): on the car when weather refreshes, and on both the car and the phone at a route’s destination when a route-weather check completes. Providers derive approximate location (city, region, country) from IP addresses, which we keep per market during the beta; analytics never contain your coordinates.
For driving safety they also describe the car in coarse categories — never a VIN, speed, route or location trace. On the car: its catalog make, model, year and powertrain; whether it is parked or driving and which signal said so; from 1.37.30, for an alert that arrives while the app is closed or cannot tell, the alert check reads the car’s own signals once (no new permission, never speed or location) so a non-severe alert does not pop up while driving, and records whether the open app, that check or neither answered; the gear category (park, neutral, drive, reverse, other, absent) when that changes; the driving restrictions the car reports; and one of five bands for how far it moved between sessions. On Android Auto: Android Auto’s package name, version and car-app level, and whether the car was parked or driving. Severe-weather notifications record a short hash of the public alert’s ID, which can indicate roughly where an alert applied.
Storage and deletion
Weather caches, your last reading, saved places and settings stay on the device (the car keeps its last location encrypted). Clearing the app’s data or uninstalling removes them and resets its installation IDs, but not records already sent: Crashlytics keeps crash reports about 90 days, PostHog keeps events 12 months, and our warehouse keeps analytics without a fixed expiry. Those records carry no name or contact details, so we cannot look them up by person.
This website
The site uses PostHog page analytics with in-memory persistence: page views, exits and interactions, page addresses and referrers, and the IP address with its approximate location. It sets no persistent analytics cookies, records no sessions and honors Do Not Track.
Other
The app is not directed at children. It is free for personal, non-commercial use under our Terms of Service; weather can be wrong, late or unavailable, so never rely on it for safety-critical decisions or let it distract you from driving. Data may be processed outside your country. This policy changes with the app; the date above marks this version. Contact: weather@dart.art
