So  you apply for a gun permit and it's either granted or denied. But if you live in California this happens according to CBS Los Angeles.

Personal information of every Californian who applied for a gun permit was released. It went back to 2011.                                                                        

An employee in the AG's office leaked names, birth dates, gender, race, driver's license numbers, addresses, and criminal history, AG Bonta said. Data from several dashboards was also impacted, including Assault Weapon Registry, Handguns Certified for Sale, Dealer Record of Sale, Firearm Certificate Safety, and Gun Violence Restraining Order dashboards.
