Math Passage — Privacy

Math Passage is a math game for children, made by RKane Games. A grown-up signs in; children never do.

What we keep

The grown-up's email address, and their Google account number if they sign in with Google. We use it only to sign in and to send sign-in codes.
Each player's nickname and color, which the grown-up chooses. We never ask for a child's real name, age or birthday.
Each player's progress in the game, so it follows them to any device.
We look at combined, anonymous numbers, such as how long a stop takes on average, to see where the game is too hard or too easy.
While the game is open, it tells our server once a minute that a game is open, so we can count how many play at the same time. When an account or a player is deleted, their play becomes part of daily totals that say nothing about who.
A count of what is bought in the game's shop with gems: the item, its price, the region and the day. It doesn't say who bought it.
To stop sign-in codes being sent over and over, a scrambled form of the address and of the network a code was asked from is kept for one day, then deleted.

No ads, and no advertising ids.
No location.
We don't sell or share anything with anyone. Our host, Cloudflare, stores it for us, and Google confirms sign-ins if you choose Google.
One cookie keeps you signed in on your device. There are no tracking cookies.

In the game: on Who's playing?, tap Sign out, then Delete account instead, type your email and confirm. The account, every player and all progress are deleted from every device, right away.
On the web: mathpassage.com/delete-account.
A player can be removed on its own by holding its tile for 2 seconds.
