Ting Budong (聽不懂) is a free app for practising Traditional Chinese handwriting. This policy explains the little data it handles.
If you set a username, we store that username, a random device key the app generates (so only your device can change your data), your points totals (today's points and your all-time total) and practice progress (your HSK-level progress figures, including a day-by-day tally of points and progress for the last two weeks, which powers the graph other users see if they add your exact username). If you allow notifications, we also store your device's anonymous push token so we can send you one daily progress reminder; turn the NOTIFICATIONS switch off in Settings to stop these at any time. That's all. We do not collect your name, email address, phone number, location, contacts, photos, or any other device identifiers, and there are no analytics or advertising trackers of any kind.
Solely to show you and the friends you choose to add a shared points table. Your username and points are visible only to someone who knows and adds your exact username; nothing is posted publicly.
Nothing leaves your phone — your practice history lives only on your device.
We never sell or share your data with third parties. Data is stored on our own server and used only to run the app.
Open Settings in the app and choose Delete username to erase your username and points from our server immediately. You can also email us and we will delete them for you.
The app is suitable for all ages and collects no personal information beyond a self-chosen username.
