MetaGer is a metasearch engine focused on protecting users' privacy. Based in Germany, and hosted as a cooperation between the German NGO 'SUMA-EV - Association for Free Access to Knowledge' and the University of Hannover, the system is built on 24 small-scale web crawlers under MetaGer's own control. In September 2013, MetaGer launched MetaGer.net, an English-language version of their search engine.

And it was initially founded in 1996!

There is a TOR-hidden service too:

It is open source:

And other useful features, for example:

That you can hide yourself behind our proxyserver just by opening the result anonymously? Use "OPEN ANONYMOUSLY"; this also affects the following links.

Alternatively I use some SearxNG-instances, preferably hosted in the EU:
