A article about if Ecosia is really a private search engine.
I did spend a lot a time to analyze and investigate Ecosia, I hope this article helps people to better understand how private is Ecosia really and which are the downsides of it. Is the first article I ever written, so it isn't perfect. I'm open for feedback!
There's something extra to keep about: They also load thumbnails direct from Bing - if you search "Hello world" you should get some video thumbnails. So that's more IP leakage to Bing.
Their results page includes a referrer meta tag with value "origin-when-cross-origin" so your browser will disclose that you're searching from Ecosia (but not what you're searching for).
