Privacy

• You can practise without an account. Then your progress stays in your own browser.
• An account keeps your email address, the name you choose, and your practice record.
• We use what we keep only to run the site. We show no ads, sell nothing, and use no tracking or analytics services.
• You can delete your account yourself on your Profile page.

Your answers, bookmarks and settings are saved in your browser's own storage on your device. We don't receive them. Clearing your browser's site data removes them.

When you make an account, we keep:

• Your email address, so you can sign in. If you sign in with Google, Google tells us your email address, the name on your Google account and your Google profile photo. We use the name only to suggest a display name, which you can change. We don't receive your Google password or anything else from your Google account.
• The name you choose to be shown on the site, your level, and your settings.
• Your practice record: which questions you answered and whether you were right, the days you practised, your bookmarks and flashcard ratings, and questions you mark “still don't get it”.
• Problems you report about a question, with what you write and the answer you gave.

If you sign up with an email address and password, our sign-in service stores your password only in scrambled (hashed) form. Nobody at SciBowl.club can read it.

A coach can keep a club roster and record live practices: which player buzzed on which question, and whether they were right. The coach types the players' names into the roster. Only the coach and the club's co-coaches can see the roster and those records. If a coach invites you by email, we keep that address with the invitation.

If you join a coach's club with your own account, your coach can also see your online practice record, including practice from before you joined: how much you practised, on which days, and how often you were right in each subject. Your club's page shows you exactly what your coach sees. Your coach sees how many players marked a question “still don't get it”, never who. You can leave a club at any time, and your coach then stops seeing your online practice. Records of live practices you took part in stay with the club.

A coach can share a read-only link to a practice record, which shows the names of the players who buzzed. Anyone with that link can open it, so coaches should share it only with people they trust.

• You can see your practice record on your Stats page and your account on your Profile page.
• Your coaches see what the section above describes, and only while you are in their club.
• The site's administrators, who look after SciBowl.club, can see accounts and records when they need to fix a problem or answer a question you sent.
• Nobody else. We don't sell, rent or give your information to anyone for advertising or marketing.

These companies store or carry data for us, and use it only to provide their service:

• Supabase runs our database and sign-in, sends password-reset emails, and stores the site's audio files.
• Vercel hosts the website. Like any web host, it keeps short-lived logs of requests, including IP addresses, to keep the site running and secure.
• Google signs you in, only if you choose “Sign in with Google”. If you sign in with Google and haven't picked an emoji picture, your browser loads your profile photo from Google.
• jsDelivr delivers the style sheet that formats math and chemistry. Your browser asks it for that file, as it would any web server.

We don't send anything you write or answer to AI services.

We use cookies only to keep you signed in. We also use your browser's storage to remember your progress, your settings and where you were in a round. We use no advertising cookies and no tracking cookies. When you sign out, the site clears your account's data from that browser.

Many of our users are middle and high school students. We ask only for an email address and a name to show on the site, which doesn't have to be your real name. If you are a parent or teacher and believe a child has given us information without permission, write to sciencebowl@prismsus.org and we will delete it.

We keep your account and practice record until you delete them. To delete your account, open your Profile page and choose Delete my account. That removes your account and your practice record. Your name on a coach's roster, and the live practices you took part in, stay with the coach's club without a link to your account. A coach whose club holds practice records hands the club to another coach first. You can also ask us to delete your information by writing to sciencebowl@prismsus.org from the email address you sign in with.

If we change what we keep or how we use it, we will update this page and the date at the top. Questions are welcome at sciencebowl@prismsus.org. You can also read Help & About.
