Mars Fever collects no data. None.
Everything you create in the app — your child's character, their name, story choices, and reading progress — is stored only on your device. It is never uploaded, transmitted, or shared. The app contains no accounts, no analytics, no advertising, no tracking, and no third-party SDKs that collect data.
Purchases are processed by Apple through the App Store; we receive no personal information from them.
If you delete the app, everything it stored goes with it.
