What's permission to clipboard needed for? Really privacy extension as the author state?
Stay away from this until it's clarified what's the clipboard access is for. A closed source extensions doesn't make things better and one can't check what the ext is doing with clipboard entries.
YOU'VE BEEN WARNED!

While IPv4 & IPv6 address location database updates continue to occur monthly, the Geotool is largely dysfunctional.

The flag is mostly replaced by the default "green globe" with returns centered on a U.S.A map at Cheney Reserve, Kansas. Or a world map. That said, for some sites, it still works OK.

Extensions are OK.

Access your data for all web sites
Get data from the clipboard
Input data to the clipboard
Display notifications to you
Access browser tabs

ask for too much access of personal data. why they need it for? sell them to third party? is just a scam used by the author to build another app using the data he collect with this app avoiding to buy that info he needs.

I wish I could use this but the flag icons are too ugly.
