Is IP Whois safe?

Low risk

IP Whois sends active-tab site IP geolocation lookups to ip-api.com over plaintext HTTP.

When tabs activate, navigate, or the browser window regains focus, IP Whois reads the current tab URL and resolves the site's hostname. It then requests geolocation details from ip-api.com for that IP address, or sends the hostname if DNS resolution does not return an address, using plaintext HTTP.

Where it sends data

Destinations our analysis observed IP Whois 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.
