What the extension collects

The extension only reads your wants list page on Cardmarket. For a list you chose to share, it sends to the server: the cards (name, quantity, expansion, languages, minimum condition, foil, wanted price, Cardmarket product ids), the list name and your Cardmarket username.

Once the list is shared, the extension syncs it again when you open your list or change your wants on Cardmarket. It does not read your Cardmarket credentials, cart, orders or browsing history.

There is no account: the extension generates a random key, stored in your browser, which proves you own your lists. The server only keeps a hash of it.

What is public

A shared list can be seen by anyone who has its link. You can make it private at any time from your wants page: it is then no longer accessible.

Website visitors

The website measures its audience with self-hosted Umami, without cookies or personal data. A “lang” cookie remembers the language you pick.

Your IP address is used temporarily, in memory, to limit abuse (request rate). It is not stored.

Card images are loaded from Scryfall and flags from jsDelivr: your browser fetches them directly from these services. Prices come from Cardmarket's public price guide.

Retention and sharing

Lists are kept as long as they exist. No data is sold, shared with third parties or used for advertising.

To permanently delete your lists or exercise your rights (access, correction, deletion), write to sieg.alexandre@gmail.com.
