What does SESK know about me?
Very little. You can play without telling us anything. If you add your email, we use it only for sign-in codes and, if you choose, SESK news. We never show or sell it, and there is no ad tracking. We use Cloudflare Web Analytics and our own Umami, both cookie-free. Full details at /privacy/.
The short version: you can play right away without telling us anything.
- Your email is used for two things: your 6-digit sign-in codes and, only if you tick the box, SESK news now and then. Turn news off any time on /me/. We never show your email and never sell or share it.
- Your player name, avatar, score and day streak are public on the leaderboard. Pick a nickname.
- Which courses you take is never shown to anyone.
- Guests are recognized with a sign-in cookie and a device fingerprint, used only to find guest progress again. It is deleted when you save your progress with your email.
- No ad tracking.
Tools we use:
- Cloudflare Web Analytics: page views and speed, no cookies.
- Umami, which we host ourselves: visits and pages, no cookies, no personal data.
- Our own game statistics: which cards are shown, answers, likes, shares and joke votes, to improve the cards.
- YouTube loads only when you tap play on a video.
- DeepSeek, an outside AI, helps write study game cards and answers Ask SESK questions. It only gets text after personal details are removed.
