- No account. You never sign up or sign in. The app has no name, email address or password to ask for.
- No location. The app never asks for your location. It shows the weather at race circuits, wherever you are.
- No ads, no tracking. No advertising and no analytics of our own in the app; Mapbox's anonymous map statistics are in section 3. Nothing follows you across other apps or websites.
- Notifications only if you allow them. Until you allow notifications, the app sends our server nothing about your phone.
Notifications
When you allow notifications, iOS gives the app a push token: the address Apple's push service uses to reach the app on your phone. The app sends it to our server with what the server needs to write and time your alerts:
- Push token
- The address for Apple's push service, and which of Apple's two push servers it belongs to (test builds or the App Store).
- Time zone
- Your phone's time zone, so an alert says 14:00 in your own clock.
- Times and Units
- From Settings: whether alerts use your clock or the circuit's, and metric or imperial.
- What you follow
- The series you follow, the races whose bell you rang, the races you muted and which kinds of alert you have on.
- App version
- The version installed, and whether it has Pro alerts (every version does for now).
Where it is kept. One row per phone in our database at Supabase, in Ireland (AWS eu-west-1). Only the server that sends alerts reads it. Nothing in the row names you, so nobody can look a row up by your name, email address or phone number. Alerts waiting to go out sit in a queue and are deleted once sent.
How long, and how to remove it. The row is kept while the app on your phone can still receive alerts. Delete the app and Apple's push service starts refusing alerts for it; the first time an alert to your phone is refused, our server deletes the row. Turning notifications off in iOS Settings stops alerts from appearing, but it never reaches our server, so the row stays until the app is deleted.
While notifications are allowed, the app sends the row again whenever you change one of these settings, and when you open it a day or more after it last did.
On your phone
Your settings stay on your phone: units, times, the map, the series you follow, the races whose bell you rang and which session intros you have seen. Radar images, terrain and the race calendar are kept in the app's cache so they need not be fetched again, and iOS may clear that cache when space runs low. Deleting the app removes all of it.
Services the app uses
The app fetches the map and the weather from these services directly. Each one sees your phone's IP address with every request, as any server on the internet does, and keeps its own request logs under its own policy. We store no IP addresses in our database.
- Mapbox
- Draws the map, the satellite imagery and the place names. Its software in the app sends Mapbox anonymous usage and performance data, with an identifier Mapbox uses to count monthly users for billing. It gets no location from your phone, since the app never asks for one. To stop it, tap the map's info button, then Mapbox Telemetry, then Stop Participating. Mapbox's privacy policy
- LibreWXR
- Radar images and the radar's forecast for the next hour, fetched by map area and time from its public server. librewxr.net
- Terrain Tiles on AWS
- The height of the ground for the 3D map, from Amazon's registry of open data. AWS privacy notice
- Supabase, our server
- In Ireland: the race calendar, the forecast at each circuit, live timing and the notification row in section 1. Requests carry the app's public key and nothing about you. Supabase's privacy policy
- Apple
- Delivers the notifications. If you share analytics with app developers (iOS Settings, Privacy & Security, Analytics & Improvements), Apple passes us crash reports and usage totals that do not identify you. In TestFlight, the feedback and crash reports testers send reach us through Apple too. Apple's privacy policy
The forecasts come from Pirate Weather and Open-Meteo, which only our server calls, once per circuit for everyone. They never hear from your phone.

- Vercel Web Analytics
- Counts page views. It tells visits apart by a hash of the request, which it discards after 24 hours, and records the page, the site you came from, your country and city as read from the connection, and your browser, system and kind of device. How it works
- Vercel Speed Insights
- Measures how fast each page loads, with the browser, kind of device, network speed and country, tied to no visitor.
- Map tiles
- Your browser fetches the map from OpenFreeMap, satellite images from EOX when you choose satellite, and the height of the ground from AWS.
- Your settings
- Units, times, the map's view and whether you have seen the letter and the guide are kept in your browser's local storage. They never leave your browser.
Your rights
trackweather is made by Arjan de Wit (Appmantle), who is responsible for this data. You can ask what we hold about you, and have it corrected or deleted, by writing to arjanwit@gmail.com. Because nothing we hold names you, we have no way to find your notification row from your name or email address: deleting the app is how to remove it. You can also complain to the data protection authority in your country.
When this policy changes, the date at the top changes with it.
