Company

Roster

Muster Defense LLC. Founder-led. Veteran-owned. The name comes from the Revolutionary call to muster: to assemble. We are not a government app and do not claim official status.

Field software people can trust because it does not phone home.

Principles

01

On-device by default

Scans, maps, and notes stay on the phone. The app works without a cloud account. If data leaves the device, you choose that.

02

We sell software, not your scans

We charge for the app. We do not sell what you scan, where you went, or who you watched.

03

Authorized use only

Use it where you have a right to be. The software does not grant permission you do not already have.
