Addition Adventure ("the app") is a math game for kids. It's built to respect your family's privacy completely. The short version: the app collects nothing and sends nothing anywhere.
Information we collect. None. The app does not collect, store off-device, transmit, or share any personal information about you or your child. There are no user accounts, no sign-in, and no way to enter an email address, phone number, or other contact detail.
Information stored on the device. The app saves a player's progress — things like a chosen name or nickname, avatar, stars earned, and which facts have been practiced — only on the device itself. This information never leaves the device and is not uploaded anywhere. Deleting the app removes it.
Internet and third parties. The app works entirely offline. It does not connect to the internet, does not contain advertising, and does not include any third-party analytics, tracking, or advertising software.
Children's privacy. Because the app collects no data at all, it does not knowingly collect personal information from children under 13 (or the equivalent minimum age in your country). It's designed to comply with COPPA and Apple's guidelines for apps directed at kids.
Purchases. The app contains no in-app purchases and no subscriptions.
