W WEATHER · last updated 14 September 2026
W WEATHER shows the weather forecast at any point you tap on a map. It is made by one person, and it is built so that nothing about you needs to leave your phone except the questions the app has to ask the weather and map services in order to answer you.
All of it is kept in your browser's or the app's own local storage, on the phone. None of it is transmitted to me.
| What | Why |
|---|---|
| Your settings: language, units, temperature scale, time format, which card fields to show, whether the relief and the timeline are on | So the app behaves the same next time you open it |
| The last point you looked at and its forecast | So the app opens where you left it and stays readable without a connection |
| Your saved places and your recent searches | So the place box can list them |
| The map areas you have looked at | So the map stays readable without a connection |
You can erase all of it at any time by clearing the app's storage in Android settings, or your site data if you use it in a browser.
The app asks for your location on the first open so the map can land where you are, and whenever you tap the my location button. Your position is used for exactly one thing: placing the point on the map, on your device. If your last point was your own position, the next open moves it to where the phone is, still on your device.
No history of positions is kept, and your position is never sent to me. You can refuse the permission and tap the map instead; everything else works the same.
To answer you, the app has to ask other services, and each request goes straight from your device to that service. This is what each one receives. As with any website, each of them also sees your IP address.
| Service | What it receives |
|---|---|
| Open-Meteo | The coordinates of the points you ask a forecast for, and the place name you type in the place box |
| OpenFreeMap | Which map tiles to draw, that is the area you are looking at |
| Mapterhorn, through weathergpx.com | Which relief tiles to draw, the same area, for the hillshade |
| OpenTopoData, through weathergpx.com | The coordinates of the active point, for its elevation |
| RainViewer | Which radar tiles to draw, only while the radar is on |
| NASA FIRMS and GDACS | The area you are looking at, only while fires or hazards are switched on |
None of these requests carries a name, an identifier or anything that links them to you beyond the IP address every website sees. Each service has its own privacy policy.
Nothing on purpose. There is no account and no server of mine collecting anything from this app. Two of the requests above pass through my server at weathergpx.com, the elevation of the active point and the relief tiles, because those two sources need a small helper in between. The hosting provider keeps ordinary web server logs for them, such as the IP address and the time of the request, in the same way every website does. These are not used to build any profile and are not linked to a person.
If you use the web version, the pages themselves are served from the same hosting, with the same ordinary logs. The Android app carries its own files and does not load pages from the site.
If you email me, I have your email address and whatever you put in the message, for as long as I keep the correspondence.
The Android app is the same app in a native shell. It uses your location in the same way and stores the same things, in its own storage. Google Play knows that you installed it, as for any app, and handles any purchase made through it; I receive no name or payment detail from Play.
This app is a weather tool for everyone and collects nothing, from anyone.
Because I hold no data about you, there is nothing for me to show you, correct or delete, unless you have emailed me. In that case, ask and I will delete the correspondence.
If this policy changes, the date at the top changes with it. If a change ever meant the app started collecting something, it would be announced in the app's version history rather than quietly edited in here.
