Math Crosswords is a number crossword you play in the browser. You place number tiles so that every equation is true.
Accounts are optional. You can play as a guest.
If you create an account with email and password, the app stores your email, your password in protected form, and your name if you give one. The name is shown on your profile.
If you sign in with Google, Google shares your email address, your name, and your profile photo. The app uses those to sign you in and to show your name and photo on your profile. The app does not receive your Google password.
For each difficulty, Easy, Medium, Hard, and Expert, the app stores how many games you started, how many you won, and your best time. Signed-in totals are saved with the account. Guest totals stay on this device only. Starting a new puzzle counts as a game started. Restarting the same puzzle does not. A win is recorded once.
A signed-in player can delete the account from the profile. That deletes the account and its stats and cannot be undone. Guest totals on that device are cleared at the same time.
The site shows ads through Google AdSense. Ads and their cookies load after the player accepts the consent message. Google may use cookies to show and measure ads. The player can refuse ads in that message.
This information is used to run the game, keep stats, sign the player in, and show ads. Personal information is not sold.
