a) The add-on itself does not record anything like ip or search terms.
- the relay site to the many newspapers - might save search terms internally, but they will never be posted, so nobody should post disturbing 'searches' into the net. Ips are saved by PLESK on my providers files and visible to me without direct linkage to the questions.
c) some 3rd party ressources spill the users search requests in a google accessible way into the general web without any responsibility or approval of legality. This could not be validated by yesterdays searches, but I have observed this trouble while benchmarking my ressource.
