Privacy & cookies

Your collection & watchlist

Anything you add to your collection or watchlist is stored only in your own browser (localStorage). It never leaves your device and is never uploaded to us. Clearing your browser data removes it; export a CSV first if you want a backup.

Server logs

Like any website, our hosting (Railway) and network provider (Cloudflare) process standard request data — IP address, browser type, pages requested — to serve the site, keep it secure, and prevent abuse.

Advertising cookies

DeckSpec is supported by advertising. We use Google AdSense, which — and its partners — may use cookies and similar technologies to serve and measure ads, including personalized ads based on your prior visits. Google’s use of advertising cookies is described in its Privacy Policy.

Where required (e.g. the EEA and UK), we present a consent choice before personalized ads are served, via Google’s certified consent message. You can also manage ad personalization at Google My Ad Center and opt out of third-party vendor cookies at aboutads.info/choices. Blocking cookies in your browser also disables them here.

Third-party content & links

Card images and prices are served by third parties (Scryfall, pokemontcg.io, YGOPRODeck), so those hosts receive requests when images load. Card pages also link out to marketplaces (TCGplayer, eBay, Card Kingdom); some of these may be affiliate links, meaning we could earn a commission on a resulting purchase at no extra cost to you. Those sites have their own privacy policies.
