Is Tool EOP safe?

Low risk

Tool EOP sends EOP task questions, answers, course identifiers, and image URLs to Tool EOP backends.

On EOP task and course pages, the extension reads breadcrumb and page content to collect user, course, unit, task, question, selected or typed answer, and image URL details. Its background script posts those task-answer messages to Tool EOP backend endpoints for answer-related features.

Where it sends data

Destinations our analysis observed Tool EOP 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.
