Question 1

Is Game Master Tools really 100% offline?

Yes. Once installed and activated with your license key, the application requires zero internet connectivity. It makes no tracking or telemetry requests, and stores your campaigns purely as Markdown (.md) files on your local drive.

How does billing work, especially in Brazil?

Accepted Answer

Our merchant of record safely handles all international taxes, local currency conversions, and Brazilian payment methods (including instant Pix and national cards) without requiring foreign exchange surcharges.

Question 3

How is my campaign data stored and protected?

Accepted Answer

All your campaigns, worldbuilding codexes, and notes are stored strictly locally on your machine in plain Markdown (.md) and open formats. There is no cloud lock-in, zero telemetry, and you maintain 100% ownership and portability over all your files.

Question 4

Which operating systems are supported?

Accepted Answer

Game Master Tools is natively available for Windows (10/11) and Linux (Ubuntu, Debian, Fedora, Arch via AppImage, deb, and tar.gz). macOS is currently not supported.

Question 5

Are future updates included with my purchase?
