What Gunmark doesn’t do
There is no Gunmark account and no Gunmark server holding your collection. Gunmark uses no third-party analytics or ad services, and doesn’t track how you use the app. Read the privacy policy for the full version.
Lock the app
Turn on the optional Face ID or Touch ID lock in Settings. Apple’s system handles the authentication on your device. The biometric data never reaches Gunmark or Big Beard Apps.

Recently Deleted
Parts, photos and maintenance entries you delete go into a 30-day hold. You can restore them from Recently Deleted in Settings.
Need help
Email support@bigbeardapps.com. Please don’t send serial numbers or photos of your collection unless we ask.
