Privacy
This page keeps nothing about you that leaves your device. No account, no ads, no analytics, no tracking, no location.
The short version
- Looking is free and needs no login.
- What you type in the bar is read in your browser. It is not stored and not sent anywhere.
- Your location is never asked for. Tools use the place you chose or typed (Des Moines if none).
- Nothing leaves this page until you tap the one tool that needs it. Then only that tool talks to its one host.
What stays on this device
Only if your browser allows it, and only on this device:
- Small preferences: who you are looking as in the demo, which layers are on, Motion, Glow, and °F or °C.
- What you write in Notes and tasks, and lines you add to the Calendar.
- Footprints: up to 12 places you have been, only if you said yes when asked.
- On the hosted site, a saved copy of the site's own files so it opens without the internet.
A statement (CSV) or a photo you open is read in the browser and never saved or sent. Settings → Forget this device clears everything C3 kept here.
Which outside hosts are contacted, and only on which tap
| Host | When | What is sent |
|---|---|---|
| api.open-meteo.com | Opening Weather | The city-level position of the place shown. No key, no cookies, no referrer. |
| all.api.radio-browser.info (then de1 / de2) | Opening Radio | The city-level position of the place shown, to list stations near it. |
| A station's own stream host | Tapping a station in Radio | A request for that station's audio, straight from the station. |
| Your browser maker's speech service (some browsers) | Tapping Say it | Your voice, by the browser's own speech-to-text. That is outside this page. |
| overpass-api.de | Only if you switch on Live towns in Settings, then open the Town rung of a town that has no pack | The box of that town (city-level), to get its building shapes. Off unless you switch it on. |
| tile.googleapis.com | Only if you switch on Photo-real cities in Settings and type your own Google key, then open the Earth rung or a real town | Your key and the view's tile requests, to Google. Use of that layer is subject to the Google Maps / Google Earth Additional Terms of Service and the Google Privacy Policy (both leave this page). Off unless you switch it on. |
| The site behind a door | Tapping a door's link | You leave this page for that site. Its own privacy rules apply there. |
The microphone (Tuner, Say it), the camera (live Scan it) and the motion sensors (Compass heading, Level) are asked for only when you tap them, and are released when you stop or leave the tool. Nothing they hear or see is recorded or sent.
Real towns: each town's buildings come with this site (Buildings © OpenStreetMap contributors; ground from USGS 3DEP) and are fetched from this site only when you open that town. Your Google key, if you type one, is kept on this device only and is removed by Forget this device.
No analytics, no location
There is no analytics script, no counter, no cookie and no fingerprinting on this page. Location is never requested.
Hosting
Like any website, the host that serves these files processes each request (including your network address) to deliver the page. This test site keeps no logs of its own.
