Device and interaction research
This page measures browser capabilities, device fingerprints, and interaction timing and movement, including the verification exercise. We do not collect typed text, passwords, camera images, or microphone recordings. Data is stored privately on Cloudflare for 30 days.
General interaction sampling lasts up to 90 seconds. Verification outcomes are recorded while the page is open. Turning collection off stops new measurements; it does not delete data already received.
