Do Google check private google sheets?

I save my Web 2.0s logins and PBNs networks logins and details on Google sheets.
Also all SEO tactics I use I save it on Google documents by details.

Once, I wondered what if google can access into these sheets and deindex all my fuc**ng networks and web 2.0s.

Is it possible? I don't think that google can put their brand name into risk through accessing private documents..

Thanks in advance!
