Privacy Policy
HanTwist keeps your learning activity on your device. You do not need an app account. The app has no advertising or analytics SDKs.
What stays on your device
Challenge progress, results, discovered expressions, and reading and audio preferences are stored locally. Word searches run on your device. We do not receive this learning information on a developer-operated server, and we do not provide an account-based progress-sync service.
Questions, illustrations, Mandarin pronunciation, and conversations are included in the app. The voices were synthesized during content production. The app does not record your voice or send it to a speech service.
Purchases
Apple processes in-app purchases and restoration through your Apple Account. We do not receive your payment-card details. The app uses purchase information supplied by Apple's StoreKit to determine access to a purchased volume. Buying or restoring content requires a connection to the App Store. Apple's services follow Apple's privacy policy.
Support emails
If you email us, we receive your email address and the information you include so that we can respond to your request. Do not send passwords or payment-card details. Support messages are kept as needed to handle and follow up your request and to meet applicable legal obligations. You can contact us to request deletion of support correspondence, subject to those obligations.
This website and external links
Privacy, support, and definition links open external webpages when you choose them. This support site does not include analytics scripts or advertising. Its hosting provider, Cloudflare, may process technical connection information, such as IP addresses and request details, to deliver and protect the site. Other websites have their own privacy practices.
Your choices and deletion
You can change reading and audio preferences in Settings. Deleting the app removes its local app data from that device. Device backups managed by Apple may contain copies and can be managed in Apple's settings. Deleting the app does not erase Apple's purchase records.
Restore purchases restores access to an eligible purchased volume. It does not restore or transfer your local learning progress.
Contact and updates
For privacy questions or requests, email johnnyiiiii@163.com. We will update this policy if the app's data practices change; the date at the top shows the latest revision.
