Ownership Disclosure

MarketLair is run by the same person behind ProxyLair, a custom TCG proxy card design and production studio. We're upfront about that connection anywhere the two come up -- if an article mentions ProxyLair, treat it the same way you'd treat any other disclosed relationship on this site.

Push Notifications & Data

If you click "Get price alerts," your browser stores a notification token (a random ID tied to your browser install, not to you personally), along with which games you chose to follow and your browser's user-agent string. If you've added cards to your watchlist (the heart button on mover cards), we also store which cards those are, so we can alert you when one of them moves even outside your followed games -- that list stays in sync with your watchlist automatically. We use all of this only to send you the weekly price-mover digest you signed up for -- we don't sell it, share it, or use it for anything else. Click "Manage" next to the alerts indicator any time to change which games you follow or turn alerts off entirely, which deletes that data (your watchlist itself lives only in your browser, separately -- turning off alerts doesn't clear it). We don't use tracking cookies or run analytics on this site beyond basic, aggregate hosting logs.
