Frequently Asked Questions

How do I register a new ball position?

Tap the + button → tap each ball on the table to set the cue ball, 1st object ball, and 2nd object ball → draw the cue ball path → fill in the technique notes → Save.

Do I need an account?

No. Every recording feature works signed out, and your data stays on your device. Sign in only if you want the same notes on more than one device.

Can I sync across devices?

Yes. Sign in with Google or Apple from the Settings screen. Your shots and groups are then backed up and restored automatically wherever you sign in.

Where is my data stored?

On your device: a local file in the app’s Documents folder. This works without an account.
Firebase: optional, only after you sign in.

You can stop cloud sync at any time by signing out.

How do I delete my account and data?

Open Settings in the app and tap Sign Out.
To delete cloud-stored data, email avata99@gmail.com with “Delete account” in the subject and the address you signed in with. Your data is removed within 7 business days.
To wipe local data, uninstall the app.

Why does the app ask for camera and photo permissions?

The photo capture feature lets you take or pick a photo of a real billiard table so the app can detect ball positions. The permissions are used only for that feature, and only when you start it.

Does the app show ads?

Yes — a banner ad (Google AdMob). Ads keep the app free.

What languages are supported?

Korean, English, Japanese, German, Spanish, French, Dutch, Turkish, Vietnamese. You can change the language in Settings.
