What we store

When you build a deck, we save it to its own page at a link anyone can open. The page shows the deck, the commander, the budget, and the text you typed to ask for it, so don't put anything private in a deck request. Quiz and bracket-checker results are saved the same way, at a link of their own: your answers become a result, and the bracket checker keeps the decklist you pasted. We count how many times a saved page is viewed.

Your browser also keeps a few things on your own device (local storage): a list of decks you've built, so "Your decks" works without an account, your page-view preference, and a build in progress so it survives leaving the page. We never see these. Clearing your browser data removes them.

What we send to other companies

The text of your deck request goes to an AI model provider (through OpenRouter) so it can write the deck. Card data and card images come from Scryfall. The buy links on deck pages go to Mana Pool and TCGplayer, and we may earn a commission if you buy through them. The page loads its fonts from Google Fonts and a script library from unpkg.

Analytics

We use Google Analytics to count visits and see which pages people use. It sets cookies in your browser and records things like the pages you view, roughly where you are, and what device you use.

Ads

We show ads served by Google AdSense. Google and its partners use cookies to serve ads based on a user's prior visits to this and other websites. You can read how Google does this in How Google uses information from sites that use its services.
