Nothing to hand over.
The whole point of GM Daemon is that your game is yours. Here is exactly where your data lives and where it doesn’t.
Your campaign stays on your computer
GM Daemon is a desktop app. Your NPCs, notes, maps, character sheets, uploaded files, and everything else live in a local database on your own machine. None of it is sent to us, and there is no GM Daemon account to create.
When you back up or export a campaign, the file is written to a location you choose on your own disk. You decide where it goes and who, if anyone, ever sees it.
When players connect
The player table is served directly from your machine. Players on your network connect straight to your computer; there is no relay server of ours in between.
Reaching players who aren’t on your network is optional and uses Tailscale Funnel, a free third-party service you install and turn on yourself. The connection is end-to-end encrypted between each player and your computer: Tailscale relays the traffic but can’t read it, because it’s decrypted only on your machine. It stays off until you enable it, reaching it needs an invite link, and rotating that link revokes access at any time.
When you use AI
AI is off until you turn it on. When you configure a provider and use an AI feature, the app sends that request to the provider you chose: a local model on your own machine, or a cloud service under its own terms. Nothing routes through us.
The copy-and-paste provider makes no network calls of its own. The app builds a prompt for you to paste into a chat you already use, and you paste the reply back.
