Privacy

Google sign-in is optional. I use your Google account ID, name, and email to recognize your account and save activity across apps and devices. For guest access, I use your chosen display name and a temporary browser cookie.

Saved activity includes answers, scores, and classroom settings. Teachers can see results in their classrooms; other participants may see display names and scores on leaderboards. Your Google email is not shown there.

I use cookies to keep you signed in and remember classroom participation. Guest activity stays separate unless you choose to save it to your account.

I store data on my server and in encrypted backups. I use it to run the apps and provide your history. I don't sell it or use it for advertising.

I keep records until removed. You can download your history from your account. For corrections or deletion, contact me using the details on my GitHub profile. Backup copies expire according to the backup retention schedule.
