Ms. Digit is a mathematics learning app for children. This policy explains what information the app processes, when information leaves the device, and the choices available to families.

Information used by the app

Ms. Digit stores learning information on the device so that the app can provide lessons and remember progress. This can include:

• a child profile nickname;
• school grade;
• selected avatar and outfit;
• lesson progress, answers, mastery and practice history;
• XP, streaks, daily activity and other in-app rewards; and
• learning and accessibility preferences.

Families should use a nickname rather than a child's full legal name. Ms. Digit does not ask a child for an email address, phone number, home address or exact date of birth.

Optional Classroom Cloud

Classroom subscribers can choose to activate cloud save using Sign in with Apple. When cloud save is activated, the profile and learning information listed above is transmitted to Supabase and associated with a pseudonymous account identifier derived from Sign in with Apple. This is necessary to back up and restore family progress across devices.

Cloud save is optional. Learning continues locally if cloud save is not enabled or is temporarily unavailable.

Purchases

Subscriptions are processed by Apple through the App Store. Ms. Digit checks the subscription entitlement on the device but does not receive or store payment card information.

How information is used

Information is used only to:

• provide and personalize math lessons;
• save and restore progress;
