Privacy Policy

Effective 2026-07-21

Quod Erat Ludendum (“QEL,” “we”) is a math game jam operated by the Ross Mathematics Foundation. This policy explains what data we collect, why, and what we do with it. We keep it short because we collect very little.

What we collect

Why we collect it

Third parties

We do not sell your data. We do not share it with advertisers.

Public information

Anything you publish as part of a game submission — title, description, screenshots, video, your GitHub login as author — is public. Ratings you give are stored per user but shown only in aggregate.

Retention

We keep your account data as long as your account exists. Session cookies expire automatically. If you ask us to delete your account, we will remove your profile and ratings; submitted games may be retained (with authorship reassigned to a generic label) if removing them would break the historical record of a completed jam. Email us to request deletion.

Children under 13

QEL is not intended for children under 13. If you are under 13, please do not create an account. If you believe a child under 13 has provided us data, email us and we will delete it.

Your rights

You can ask us to see, correct, or delete the data we hold about you. Email ross@rossprogram.org.

Changes to this policy

If we make material changes we will post the updated policy here with a new effective date. Continued use of the site after changes take effect means you accept the new policy.
