Is Add to Buyee safe?

Clean risk

Add to Buyee sends ecommerce page origins to Buyee service endpoints for banner and shop metadata.

When pages finish loading, the extension can message its all-URLs content script to classify the active site and display Buyee UI. For ecommerce pages, it sends the page origin as a shop_url parameter to buyee.jp/externalapi/shop/type and uses the response for campaign, banner, and shop-type metadata.
