Is Calendar Extension for Google Calendar™ safe to install?
Calendar Extension for Google Calendar™ asks for 4 browser permissions and 2 site patterns. We do not audit code and we do not judge intent; what we can show is what the listing declares and whether that has changed while we have been watching.
The facts we can check
No score. A single number would compress incomparable things and imply we had weighed them: an ad blocker needs every page and a theme needs nothing, and one figure would be wrong about both.

Has it asked for more over time?
This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.
The permissions this extension requests have not changed since we started watching it.
Versions we have seen
- Version 3.0.4
