Accounts and history

AI CertArena saves progress only after you sign in with Google. We store your Google account identifier, verified email, and display name to associate completed attempts with your account.

Completed saved attempts include your answers, score, topic results, completion time, and time spent. A session cookie keeps you signed in for up to 30 days. Practice without Google sign-in is available. That result is stored with no account attached, and your browser keeps a one-time claim code so you can attach it to an account if you sign in later. The code is a random string, it is not linked to your name or email, it is deleted as soon as it is used, and any result nobody claims within 30 days is deleted from our server. An unfinished practice set is also kept in this browser so you can resume it, including the questions served and the answers you have picked. Clearing your browser data removes both.

What is public

Eligible timed practice results may appear on the leaderboard under your chosen display name. Your email and individual answers are not shown there. A result-sharing page is public only after you choose to create it from a saved result. It shows the display name you enter, track, date, score, and question count. It is excluded from our sitemap and marked not to be indexed.

Site measurement

We count daily page visits and actions such as practice starts, completions, Google sign-ins, and result sharing. These aggregate counters do not contain an email address or a visitor identifier. Server and hosting infrastructure may process request logs to operate the service.

Audio and third parties

Practice narration is generated on our server from the question bank. Your microphone is never used. Google sign-in loads Google Identity Services and is subject to Google's privacy policy. Provider links and LinkedIn sharing open those external services.

Your controls

You can export your saved history and delete your Google-linked account from My progress. Account deletion removes your sessions, saved attempts, and published practice result pages. You can separately clear a saved in-progress session from this device.
