For the most part, this is my 2nd choice chosen search engine for the obvious reason of feeling protected against the onslaught of gathering & storing of my personal information. I can’t say I know if it’s actually 100% safe in that regard, because I notice that when I press a prompt it brings up my search histories even after the website tabs have been closed, but it was only by accident that I figured out that they were there saved. I AM able to delete them, now that I know that they are actually there, but I’m able to do that on regular tracking search engines too soooo… I’m no tech person, so I don’t know all the ins & outs, & if I truly am NOT being tracked, but I still use it as my second choice after DuckDuckGo. That search engine truly doesn’t keep a record of my activity, at least I can’t find it. So I don’t think my review may provide a high degree of tech insight, but it’s (Quant) an effective means to search the web successfully while feeling a measure of protective anonymity based on what others in the field have stated.
