Is The Amazon ASIN Checker safe?
The Amazon ASIN Checker sends browsing data and account email to api.asincheckr.com and injects the server's HTML response into the page.
On Amazon product and Seller Central pages, the extension collects the ASIN, page URL, product category, and the signed-in user's email and sends them to api.asincheckr.com to check gating/qualification status. The server's JSON response includes an HTML string that the extension writes directly into the page via innerHTML, so the content shown in that banner is controlled by the vendor's backend rather than sanitized locally. Account signup, sign-in, and password-reset requests (including a plaintext email/OTP call over http://) also go to the vendor's own API domains.

Where it sends data
Destinations our analysis observed Amazon ASIN Checker contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
