Cornerman
Privacy
Cornerman collects nothing. There is no account, no analytics, no tracking, and no server to send anything to.
What is stored
Your round, warning and rest lengths, and which gym's branding you last chose, are kept in your own browser's local storage — on your device, readable only by this site. Clearing your browser data removes them. On Apple TV the same three settings live in the app's own preferences on the device.
What leaves the device
Nothing. The whole app — the artwork, the bell, the wooden clapper — is delivered in the page itself and then cached for offline use. Once it has loaded, it makes no network requests at all, which is what lets it keep working when the gym's wifi drops.
Third parties
There are none. No advertising, no analytics provider, no embedded fonts or scripts from anywhere else, no cookies.
Children
The app is rated 4+ and collects no data from anyone, of any age.
Changes
If this ever stops being true, this page changes before the app does.
