AnHot is designed so the essential screen tests run on your device.

What stays local

Test patterns are produced by your browser. We do not request screen recording, camera or microphone access. Quick Check judgments are stored only in sessionStorage for the current browser tab and can be cleared from the results screen.

Keyboard test data

The keyboard test uses physical key codes to update the on-screen layout and shows the most recent character for immediate feedback. It does not assemble, save or upload a typed message. Test state is cleared when you reset or leave the page.

Network test data

A network test sends temporary random bytes between your browser and the AnHot test node. The server counts and discards upload bytes without saving a file. Requests may expose your IP address and standard HTTP metadata to our hosting provider for delivery, abuse prevention and short-lived rate limiting. Test results are displayed in your browser and are not attached to an account.

Browser-reported display information

The site reads values such as CSS screen size, viewport size, device pixel ratio and color depth to display them back to you. Those values are not a screen capture and do not reveal a device serial number.

Cookies and analytics

AnHot does not use advertising cookies or account tracking. We use ordinary server access logs and a first-party, cookie-free counter when a Quick Check summary is copied. Daily reports contain aggregate traffic and usage totals; they do not contain typed keys, screen contents or individual test results.

AI Bubble Test voting

If you vote in the AI Bubble Test, AnHot stores a random first-party, HttpOnly cookie so your browser can keep one vote and change it later without creating another count. The database stores a one-way hash of that token, your yes/no choice and vote timestamps; it does not store your name, email address or the raw token. Votes are community sentiment and may remain in aggregate results after you stop using the site. Anonymous browser sessions cannot ensure one vote per person. Short-lived server-side rate limits may use request metadata in memory to reduce abuse; raw IP addresses are not written to the voting database.
