Is an account required?
Yes. A BallTrap OS email and password, or a Google account. There is no guest mode. An email-and-password address must be confirmed before the logbook opens.
Does it really work offline?
After a successful first sign-in, the journal, series and gun safe still work at the stand without a network. Writes stay on the device and can sync later. A new account cannot be created without that first sign-in.
Where do I download the app?
Android is coming to Google Play; the listing is not online yet. iOS soon. The web logbook is available now, behind Sign in or Open the app.
Is this an official score sheet?
No. BallTrap OS does not replace a licence, a permit, club or ground rules, or an official sheet. A score shown in the app is not a federation homologation.
Who sees my series?
Other shooters see only what features deliberately show, for example a name on a ranking or a visiting card. Not the device backup, and not a brand gallery of gun photos.
How do I delete an account?
Email BallTrap.os.infos@gmail.com. The account-deletion page describes what is erased in the cloud and what stays on the phone until uninstall.
What can a club president do?
Manage their own club: page, hours, contests and events for that club. They do not administer other clubs or every account.
Does it cost money?
No. BallTrap OS is a free hobby tool, with no subscription and no in-app payment. The app does not process payment data.
