Questions parents ask.

Does my child need an account?
No. The games never ask for your child's name, an email or a photo. The app has one save code, and you use it to link the app to your own sign-in.
Does it need the internet?
Not to play. Your child's progress is saved on the device and backed up the next time it is online. Linking the app to this website needs a connection.
What ages is it for?
Kindergarten to 5th grade, about ages 5 to 11. Questions start at your child's grade and move to the level that fits.
Do you sell my child's data?
No. There are no ads or trackers, and you can delete your child's record at any time. The privacy page lists what we keep and for how long.
