Or you can do both.
I had done this once a few years ago and then went into their preferences page and turned off the history function so according to what they tell you to your face, they do not collect and save anything after that point. (cough, cough)
Here’s How to Download and Delete What Google Search Knows About You
Daniel HowleyTechnology ReporterApril 23, 2015
Have you ever wondered what Google Search really knows about you? Well, now you can check, as Google has added a new feature that lets you view and download your entire search history.Yep. Everything.The feature, which was spotted by the unofficial Google Operating System Blog — though VentureBeat points out that the function was made available in January — gives you access to everything from what you searched for to the links you clicked on from those searches. It also shows you the addresses you’ve searched for.I was even able to see the list of images I clicked on while searching for pictures of cats eating spaghetti. Now imagine what you’ve looked for. Oh, and clearing your browser history won’t delete this data.But there’s no reason to panic, because in addition to being able to download your search history, you can clear it.
You click on that link right there and you go follow the very easy directions that nice fellow researched and published!
One warning before you run over there and just blindly go deleting it without looking, there may very well be something in there that you want to save first, this is why downloading it first is a good idea.
The reason I say that is because not only does Google save your search history, those bastards have got their fingers in all kinds of pies that you might not think of right away, like images.
I found some very old family pictures from one of my Grandmothers side that were sent to me by her cousin that Google had stored and I did not remember doing.
I looked and didn't see a copy on this computer so I am guessing that they were saved on a computer that died and I no longer own but were also on some Google Drive thingy I didn't remember either.
Seriously, I don't want to step on anyone's toe's here, all I am doing is passing on the information that it is possible to do such a thing and giving you a map to find those directions.
You can bet your ass I deleted MY history though.........
I stumbled on this over at SurvivalBlog while cruising around.
