Is Share-A-Cart safe?

Clean risk

Share-A-Cart sends cart contents and retailer metadata to its backend when you create a shared cart.

When you use Share-A-Cart to create a cart link, the extension reads the active retailer cart and sends the cart contents, store details, currency, and page URL context to its backend. The code posts this data to the Share-A-Cart save endpoint so the cart can be stored and shared.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 4 hostnames

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.
