Is Super Kulasis safe?

Low risk

Super Kulasis sends Kyoto University course and professor names from KULASIS pages to tatekan.copynight.net.

When a user views KULASIS syllabus or lecture-search pages, the content script reads course titles, evaluation text, and professor names from the page. It sends normalized course names and professor names in GET requests to tatekan.copynight.net lookup endpoints.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Where it sends data

Destinations our analysis observed Super Kulasis 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.
