Is Holiday Calendar safe?

Low risk

Holiday Calendar fetches regional calendar data over plaintext HTTP from calendar-crx.diary8.com.

When the popup loads, it requests yearly calendar JSON for the selected region from http://calendar-crx.diary8.com and stores the response in localStorage. The plaintext request exposes the calendar data URL and selected region and year to that server and to network observers between the browser and the server.

Where it sends data

Destinations our analysis observed Holiday Calendar 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.
