1. Introduction
Centre Circle Finder is a free web app by averyio, at averyio.net/centre-circle-finder, that maps every professional and semi-professional football ground in the UK. This policy explains what the app stores, what it sends, and to whom — which, in short, is: nothing about you to us. averyio runs no server behind this app and holds no data about its users.
2. What Is Stored in Your Browser
Two things, and only on your device, in your browser's local storage:
- Your ticked-off grounds — the list of grounds you have marked as visited, stored as a list of club names. It never leaves your browser unless you use Export, which saves a file to your own device.
- Your theme choice (light or dark).
Neither is transmitted anywhere. There is no account, no sign-up and no identifier of any kind. Clearing your browser's site data removes both, which is why the app offers Export. averyio never sets a cookie.
3. Your Location
If you tap Near me, the app asks your browser for your position, once, to centre the map and rank nearby grounds. That position is used entirely on your device and is never sent to averyio or to any third party. Your browser asks your permission before sharing it, and the app works fully without it. Nothing about your location is stored between visits.
4. Third-Party Services
The app runs in your browser, so your browser contacts a small number of third-party servers to make it work. Each sees the standard information any web request carries (your IP address, browser type and the resource asked for), and each is governed by its own privacy policy:
- OpenFreeMap (
tiles.openfreemap.org) serves the map tiles. - OpenStreetMap Nominatim (
nominatim.openstreetmap.org) is contacted only when you search for a place by name or postcode; the text you typed is sent so it can be turned into a map position. Searching for a club by name uses data built into the app and contacts no one. - Google Fonts serves the typefaces, and unpkg serves the MapLibre map library.
- Google Maps and X are reached only if you choose to tap Directions or Share, which open those services in a new tab.
averyio does not use analytics, tracking pixels, advertising networks or any service that profiles visitors. Nothing on this page identifies you to averyio.
5. Children's Privacy
The app is suitable for all ages. It collects no personal information from anyone, of any age.
6. Changes to This Privacy Policy
If the app ever changes what it stores or whom it contacts, this policy will be updated first, with a new effective date at the top of the page. The current version is always at this address.
