ArmoryHub is an all-in-one firearms inventory and records platform where your data is encrypted on your device before it is ever sent anywhere. It uses zero-knowledge, end-to-end encryption, so the servers that sync your collection only hold ciphertext. We can’t read your inventory, and neither can anyone who gets into our database. It runs on iPhone, iPad and Mac, and in any browser at portal.armoryhub.app, so it also works on Android, Linux and Windows. Changes sync between devices automatically. An internet connection is required. SECURITY AND PRIVACY Everything is encrypted with AES-256-GCM, including photos and documents. You unlock with a PIN, with attempts rate-limited on the server, or with an optional longer passphrase. Because we never hold your keys, we can’t recover a forgotten PIN or passphrase, so choose one you will remember. There are no ads, no third-party analytics or tracking, and no selling of data. EVERYTHING WORKS TOGETHER Every part of ArmoryHub talks to the others, so you enter things once. Log a range trip and the rounds are added to each firearm’s count, the ammunition comes out of your stock, and the trip’s cost is calculated from the ammo you used. Those round counts also drive rounds-based maintenance reminders and your rounds-since-cleaning figure. Swap a part between firearms and each one keeps the change in its own history, giving you a full change log. Log a reloading session and the components come out of your inventory while the finished rounds go into your ammo. Purchases, values and stock levels feed the dashboard and reports automatically. INVENTORY Each firearm has its own record with photos, specifications, serial number, purchase details, current value, storage location, condition and attached documents such as receipts, manuals and more. Ammunition is tracked by caliber and type with stock alerts, and is deducted automatically when you log range trips or reloads. Accessories and optics can be assigned to more than one firearm. Parts can be installed, swapped and removed between firearms, with a full change history. NFA ITEMS Track Form 1 and Form 4 submissions, tax stamp numbers, approval dates, and whether an item is registered to a trust or an individual. Wait times are calculated from your filing date. RELOADING Keep inventory of powder, primers, bullets and brass, save load recipes, and log each session with the rounds produced. Component stock goes down as you load and finished loads are added to your ammo inventory for use in range trips. RANGE TRIPS AND DOPE Log a session with several firearms and several ammunition types, add photos and notes, and record DOPE (data on previous engagement). Round counts per firearm update automatically, and the ammunition used comes out of inventory. MAINTENANCE Schedule maintenance by date or by rounds fired, get notified when it is due, and see rounds since last cleaning for each firearm. Every entry keeps its date and cost. PEOPLE AND LICENSES Record licenses, certifications and memberships for the people in your household, with expiration alerts ahead of renewals. DASHBOARD AND REPORTS The dashboard is made of cards you can drag and resize. It shows collection value by category, spending, caliber distribution, appreciation, and alerts for low stock, maintenance and NFA waits. Reports cover full inventory with photos and values, purchase and disposal logs, and maintenance history, and a custom builder with filters and saved queries lets you build your own. Export to PDF or CSV for insurance or your own records. FREE AND PRO Free includes up to 3 firearms, 3 accessories, 3 ammunition types and 1 photo per item, with the same encryption as Pro. Pro removes those limits and adds unlimited photos, reloading, range trips, reports, NFA tracking, maintenance, the dashboard, and licenses and certifications.
