Support
How can we help?
WordKin is a small, independent app. Your question reaches the developer directly.
Email support support@tsonubin.comEmail is the only support channel currently available.
Where is my study data?
Progress and review history stay on your device. WordKin does not use an account or cloud sync.
How do I reset progress?
Open Settings, choose Reset all progress, and confirm. This permanently removes the study data stored by the app.
How are the vocabulary Books built?
Licensed curriculum sources contribute headword scope only. WordKin independently selects senses, creates localized candidate glosses, derives root and meaning relationships, and rebuilds the learning graph.
