Frequently asked questions

Is this a subscription?

No. $15 once. The license is valid forever and covers all Gudrun updates.

Where does the license file go?

Any one of these works:

• %APPDATA%\Gudrun\gudrun.key (Windows) or ~/.config/gudrun/gudrun.key (Linux)
• Next to the Gudrun executable
• The Import button in the reminder dialog

Does Gudrun connect to the internet?

No. The license is verified locally with a cryptographic signature. No activation servers, no telemetry, no update pings. If you never visit this site again, nothing changes.

What happens when the trial ends?

After 30 days you get a reminder dialog at startup. Every feature keeps working — nothing locks, nothing is watermarked. The license removes the reminder. We think honest software sells itself.

How many machines can I use it on?

A personal license covers you, the person — install it on your own machines. For business use, email support@midnightsoftworks.com.

Can I make my own theme?

Yes — themes are single declarative files, applied instantly, no restart. Full guide with a complete template.

Is the Windows download signed?

Yes. The installer, the app and its libraries are digitally signed by Midnight Softworks, and Windows shows that name as the publisher. Version 1.0.0 predates signing; if you have it, or if SmartScreen still asks about a release that's only just come out, click "More info" → "Run anyway".

Refunds?

14 days, no questions asked. Reply to your receipt email or write to support@midnightsoftworks.com. Full terms.
