The Keywords Everywhere browser add-on shows you metrics (search volume, cpc, competition) for keywords. It does this by sending your keywords to our server. Our server returns back the metrics for those keywords and the add-on then shows the same keywords on the enabled sites. We do not save any keyword data that the add-on sends to our server, nor any other personal information.
As an example, if you do a search on google.com for "xbox one", the keyword phrase "xbox one" is sent to our server. Our server will lookup the metrics for this phrase and send them back to the browser add-on. The add-on will then display the search volume, cpc and competition details for this phrase underneath the search box. The server does not store the keyword phrase or any other information from this process.
If you prefer not to send the keyword data on certain websites, you can choose to disable those websites from the settings page. You can also choose to temporarily disable the add-on from the add-on's popup menu.
