Privacy
Today the site holds nothing about you. Your streak and points live in your own browser and never leave it. There is no sign-in, no tracking and no cookie beyond what the hosting needs to serve pages. The only aggregate figures are Vercel's own page counts.
If you send a submission, the text you typed, the handle you chose and the date go into the review queue, which is a GitHub issue in the site's repository. Nothing else is recorded about you.
When member accounts arrive
| Data | Why it is held | Where | Kept until |
|---|---|---|---|
| Email address | Sign-in and the magic link | Supabase Auth, London region | Account deletion |
| Handle, display name, avatar URL | Leaderboard and question credits | profiles | Account deletion |
| Answers, scores, streaks | Leaderboard and streaks | attempts, profiles | Account deletion |
| Submissions | Moderation and credit | questions, rename_submissions | Approved questions stay, credited to a former member; the rest are deleted |
| IP address | Turnstile and abuse prevention | Cloudflare and Supabase logs | Rolled over by the providers, not stored by the site |
Lawful basis
Your consent at sign-in for the profile, scores and submissions; legitimate interest for abuse prevention.
Deleting your account
One button on your profile. It anonymises approved questions, deletes your answers, submissions and profile, then deletes the sign-in record.
Where the data will live
A database in the London region, so the data, the sign-in service and any stored files stay in the UK.
What is not here
No analytics beyond the host's aggregate counts, no advertising, no passwords ever.
Questions about any of this: use the Submit page until the community address is live.
