Your safe, documented. Every firearm, serial number, receipt photo and tax stamp — organized, private, and ready the day you actually need it: an insurance claim, an estate, a stop at the range. NFA DONE PROPERLY Form 1 and Form 4, submitted and approved dates, control numbers, individual versus trust ownership with the trust name, and suppressors mapped to their host firearm. Not a checkbox labeled "NFA" — the whole paperwork trail, documented the way a stamp actually exists. CARRY LICENSES & TRAINING Track CCW licenses with issue and expiry dates, issuing authority, restrictions, and photos of the card itself. Keep your training certificates in the same place, so renewals never sneak up on you. YOUR ARSENAL Every firearm with make, model, caliber, serial number, purchase price and date, safe location, notes and photos. Organize by type — handguns, rifles, shotguns, SBRs and more. AMMO INVENTORY Know exactly what you have. Track quantity by caliber, brand, grain and bullet type. Scan UPC barcodes to add boxes fast. Set low-stock alerts so you never show up to the range short, and watch counts fall automatically as you log what you shoot. RANGE LOG & MAINTENANCE Log every trip with date, location, firearms used and rounds fired. Record cleanings, repairs and inspections tied to a specific firearm, and track rounds fired between cleanings to stay on schedule. HANDLOADING The optional Reloading Module tracks brass, bullets, powder and primers, versioned recipes, and batches with lot numbers — decrementing components as you load and working out your true cost per round. DOCUMENTATION THAT SURVIVES A CLAIM Export an insurance PDF of your collection, a CSV of your firearms, or a complete JSON backup that includes your photos and receipt images. Your records are yours, in formats you can hand to anyone. BUILT FOR PRIVACY Your data stays on your device. No account required for core features. No ads, no tracking, no data selling.
