What we do with your data
The game is made for children, so we take as little data as we can. Here is everything that is kept about you, and why.
Three things from Google
Your Google identifier, your name and your avatar. The identifier is needed to recognise you next time you sign in; the name and avatar are so your friends can see you in the room. We don’t ask for your email, password, contacts or search history: Google simply doesn’t send them to us.
What is kept on our side
The results of games played — for your statistics — and the course of each game: without it the totals can’t be recalculated. How many times anyone got their sums wrong is visible to you alone.
One cookie — for signing in
Once you have signed in, your browser keeps one cookie so that we don’t have to ask Google every time. It lives for 7 days, is not available to scripts on the page and is used for nothing but signing in. The “Sign out” button deletes it.
What stays in your browser
The theme, language and currency you chose. They are kept on your device only and are never sent to us.
What there isn’t and never will be
Advertising, third-party analytics and trackers, or passing data to anyone else. The project is non-commercial and sells nothing.
