Is UpSeller - Product Importer safe?

UpSeller captures product page HTML and Shopee authentication headers from e-commerce tabs and transmits them to app.upseller.com.

UpSeller is a product-import assistant for online sellers, injecting content scripts into over 15 e-commerce platforms including Amazon, AliExpress, Shopee, and Mercado Libre. When triggered by the UpSeller web app (via external messaging), the extension fetches the full HTML of a product page and uploads it to app.upseller.com/api/crawl/plug-crawl. On Shopee tabs, it also intercepts outgoing request headers—including authentication cookies and tokens—and replays them when making authenticated product data requests on the user's behalf.
