My TestFlight install crashed
Delete the app, reinstall, try again. If it still crashes: email me with your device model + iOS version + the last screen you saw.
My logged data is gone
Goodminton stores everything on-device. If you reinstalled the app, the data is gone (cloud sync is on the roadmap).
I want a feature
Send it via the in-app Send feedback button (Profile → Settings → Send feedback) or email me directly.
I found a bug
In the app: Profile → Settings → Report a bug. Or email kevinliu217@gmail.com.
Why does the app ask for camera / photo permissions?
Camera is used to scan racket serial numbers (T-joint OCR). Photos let you attach a racket portrait. Both are optional — the app works without them.
How do I delete all my data?
Settings → Privacy → Delete all data. This wipes the local database and resets the app to first-launch state.
