Is Smarty - Coupons & Cash Back safe?

Low risk

Smarty's opt-in Amazon Price Protection feature opens a hidden tab to scrape your Amazon order history and sends it to Smarty's servers.

When a user enables Amazon Price Protection after checkout, Smarty opens a hidden pinned browser tab and navigates it through your Amazon order-history and order-details pages. It collects each order's items (title, ASIN, quantity, price, order ID/date) and sends the full order set to api.joinsmarty.com, then repeats the scan on a recurring timer while the feature stays enabled.

Shared hosts - 14 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.
