Privacy Policy

ChessCubs is an invite-only chess coaching platform. Accounts are created by an administrator or coach, not through public sign-up — this policy explains what information the platform holds about you once you have an account, and how it's used.

Information we collect

• Account details: your name, email address, and role (student, coach, parent, or admin).
• Chess activity: games and PGN files you or your coach upload, homework assignments and submissions, puzzle attempts, lesson notes, and classroom session responses.
• Usage activity: a log of actions like viewing a game, submitting homework, or attending a class — used for coaching quality (e.g. attendance, homework completion) and to power features like “Recently Viewed.”
• For students under a parent's account: the parent can see their child's lessons, homework, and progress reports.

How we use this information

Solely to run the coaching platform itself: showing you your own games and homework, letting your coach or admin manage lessons and assignments, generating progress reports, and improving the coaching experience. We do not sell your data, and we do not use it for advertising or share it with third parties for marketing purposes.

Who can see your information

Access is role-based. Students see their own games, homework, and progress. Coaches see students assigned to them. Parents see their own linked children. Admins manage the overall platform. These boundaries are enforced at the database level (Row Level Security), not just in the app's interface.

Where data is stored

Data is stored with Supabase (hosted on infrastructure in the cloud) and the app itself is hosted on Vercel. Both are reputable infrastructure providers used by many production applications; neither has independent access to use your data for their own purposes.

Children's privacy

Many ChessCubs students are minors. Student accounts are created and managed by a coach or administrator, with a parent or guardian linked to the account and required to review and approve it, rather than the child signing up directly. Parents can request a copy of, or the deletion of, their child's data at any time by contacting us below.

For the full details of what we collect about children specifically, why, and your rights as a parent, see our Children's Privacy Notice.

Your choices

To request a copy of your data, correct inaccurate information, or have your account and associated data deleted, contact your ChessCubs administrator or email us directly (below). We will act on the request as soon as reasonably possible.
