Privacy

Last updated: July 27, 2026

The short version

• One parent account per family. Kids have no logins and are never asked for their name, age, or anything else.
• No ads. No analytics or ad trackers. We don't sell or share data for marketing.
• The only third parties are Auth0 (parent sign-in) and YouTube (the reward videos you pick).

What we collect

• Account: the parent's email and login identity, handled by Auth0, our sign-in provider; and the 4-digit PIN that keeps kids out of the settings pages.
• Settings: the skills you enable, the YouTube playlists you add, and the target percentage of time spent on math.
• Gameplay events: which problems were shown and answered, and minutes spent solving and watching. This is what enables the difficulty adaptation and the progress page.

What we never collect

• No child accounts, names, birthdays, photos, or contacts.
• No location, no microphone or camera, no address book.

Third parties

• Auth0 handles parent sign-in, so it processes the email address and credentials used to log in. See the Okta/Auth0 privacy policy.
• YouTube plays the reward videos, drawn only from playlists a parent added. When a video plays, YouTube may set cookies and collect viewing data under the Google privacy policy.
