Please can you let us know what you don't like about the policy? The extension securely sends only two things to the Wikidata Query Service: your language, and the URL you are on. And it only sends these if you click it for a particular page. We do not store any of your information. The links it provides are to sites all around the web, and obviously we can't take responsibility for what is on their pages. We have done our best to protect your privacy in every way.
