Is Label Resizer - FBA Labels to Thermal & Avery safe?

Legitimate paid SaaS tool for Amazon sellers that resizes FBA shipping labels for thermal printers. Content scripts intercept PDF label data on Amazon Seller Central and partner carrier sites (UPS, FedEx, Mercari, Walmart) and transmit it to api.labelresizer.com for server-side resizing. All data transmission is authenticated with a user account token and consistent with the extension's stated purpose. Broad host_permissions (*://*/*) are used to fetch PDFs from arbitrary marketplace URLs.
