Ist google.com sicher?

For the most part, google is very useful, and it's still my default homepage, but their tracking of your search queries is a bit of a turn-off in the privacy department and I can see the possibility of a lack in safety for unsupervised children searching randomly.

Google tracks everything you do, and it's not just on Google, it's on Youtube, it's on Yahoo, it's everywhere. Embedded on virtually every single website or domain that Google owns, as well as some that they don't, are hundreds upon HUNDREDS of trackers and LSO cookies which can be a pain to remove.

My rating for child security is far under the median. Therefore I have one major concern: can a search engine that at the same time offers links to coloring plates and cut-and-build paper train models, but on the other hand lets pass the most horrible sex, rape and bestialy scenes as well, considered as a child-friendy website? It is for an adilt rather though enough to stqy out the greay criminality sphere that Google offers under the civer of "gatherin,g information"...
