Privacy
Every game on Math Is Social runs inside your browser. The numbers, birthdays and answers you type are used only on your device to produce the reveal — they are not sent to us or stored anywhere.
No account or sign-up is needed. We don't use device fingerprinting or precise location.
To avoid repeating the same trick, your browser may remember which games you've recently played (never your answers). You can clear this at any time by clearing this site's data in your browser.
On upcoming games you can tap "I'd play this". Your browser remembers which games you tapped so it isn't counted twice. Only the game's name would ever be recorded — nothing about you.
Measurement. On mathissocial.com we use Umami Cloud, a cookie-free analytics service, to count visits and see which games people enjoy. It is not used anywhere else, and no advertising service receives anything.
What our site sends to Umami: the page address (without anything after a "?"), the address of an outside site that linked you here, if any, your browser's language setting, and simple game events with a short game label — for example "a reveal happened in Think of a Number" or "I'd play this was tapped for The 1089 Trick", plus small details such as which round of a challenge or whether a share used your device's share menu. We never send the numbers, dates or answers you type, and we set no cookies for this.
Like any web request, Umami also receives standard technical details your browser sends automatically — your IP address and browser identification — which it uses to work out device type, browser and approximate country, under Umami's own privacy practices. Blocking it in your browser doesn't affect any game.
