Is Enhanced Cardmarket safe?

Clean risk

Enhanced Cardmarket sends Cardmarket product price-chart data to api-cardmarket.mave.me by default.

On Cardmarket product pages, Enhanced Cardmarket reads the card key from the page URL and extracts price chart labels and values from the page. When its default-on price reporting option is enabled, it sends that chart data with a generated hash to api-cardmarket.mave.me/chart and records successful sends locally to avoid repeating the same card too often.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
