At Mandarin Explorer, we believe your language learning progress is your business alone. This application is engineered to protect user privacy through a completely localized data framework.
Mandarin Explorer operates entirely offline. We do not collect, harvest, track, or share any personal information, location data, usage statistics, or unique device identifiers. Your quiz scores, star counts, and mastered word data states save exclusively to your local device storage.
All transactions, downloads, and app purchases are handled securely and directly through Apple's App Store or Google Play infrastructure. We never have access to your billing details, payment methods, or personal financial records.
If you have any questions regarding this policy, please reach out via our official support email.
