Collection inventory software that keeps your records on your own devices

• Windows, Mac (Apple Silicon and Intel), Linux, Android, iPhone and iPad

• 29 ready-made collection templates, each with three sample items

• Every feature free for 30 days, no credit card

• Activations from $14.95 a year, or $82.25 for life

• The app never connects to the internet

​

Security that cloud software can’t match

​

Most collection software keeps your records on someone else’s server. NM Collector CP keeps them on yours, and the app itself never goes online.

​

• 100% offline. The app never connects to the internet, so there is no server holding your records and nothing online to breach.

• Zero data collection. No account, no tracking and no usage analytics. Nothing is collected about you or your collection.

• Your data never leaves your devices unless you move it yourself.

• Works on air-gapped computers. No network access is needed, even to activate.

• Works with the encryption built into your computer: BitLocker on Windows, FileVault on a Mac and disk encryption on Linux.

• You decide how your data moves. A USB drive, AirDrop or Quick Share keeps it on your own devices. If you choose email or a cloud service instead, the app reminds you first that your data will pass through that provider.

Start with a template made for your collection

​

Each template names the fields that tell one item apart from another and fills the drop-down lists with real choices: calibers, coin grades, stamp perforations, watch movements, wine regions. You start recording instead of designing forms. Every template can be changed, and you can build your own.

​

Firearms, Blades and Militaria: Ammo · Firearms · Knives · Militaria · Nihonto

​

Coins, Stamps and Paper: Coins · Paper Items · Sports Cards and Memorabilia · Stamps

​

Books, Music and Media: Books · Musical Instruments · Records and Media

​

Art, Antiques and Jewelry: Art and Antiques · Pens and Writing Instruments · Southwest Pottery and Jewelry · Watches and Clocks

​

Vehicles, Tools and Gear: Cameras and Lenses · Fishing Tackle · Motor Vehicles · Radios and Electronics · Tools and Shop Equipment

​

Toys, Hobbies and Nature: Rocks, Minerals and Fossils · Toys and Models · Whistles

​

Home, Household and Records: Home Inventory · Licenses · Recipes · Subscriptions · Wine and Spirits

​

What you can keep for every item

​

• The details that identify it, in fields made for your kind of collection

• Any number of pictures, each with its own notes. On a computer, drag pictures straight in from a folder.

• Where it came from and where it went: who you bought it from, the date and the price, and the same when you sell or give it away

• What it is worth: appraised, current and insured values, each with its date

• Maintenance and event logs, such as cleanings, services, shows and competitions

• Links to receipts, certificates, documents and web pages

• Related items, in the same collection or another

​

Then print inventory reports with or without pictures, acquisition and disposition reports and reports you design yourself, see cost and value totals on the statistics page, and export to CSV for a spreadsheet.

New in Beta 2.3.1

​

• Autocomplete in drop-downs. Type a few letters to find a value on the computer; tap to search the list on a phone or tablet.

• Your whole collection as one file. Share Data packs the database and every picture into one zip to move between computer, phone and tablet.

• 16 new collection types, for 29 in all, each with three sample items.

• Imports ask first. Before a template import would rename your fields, the app shows exactly what would change.

• A native Apple Silicon build for newer Macs, alongside the Intel build.

​

Beta builds are for testing and may contain bugs. Back up your data and tell us what you find.
