well, for one thing, it helped me out of my d3pression, it helped me get my art out there, helped me start a business, helped me be creative with stuff, and helped me find new hobbie like cooking and art :)
its a trusted site cuz it is. its not bad or anything, but still it does track stuff. for example, lets say your friend just told you they are gonna have a baby. cool right? then when you go on google itll show you a bunch of reccomended dipers, or baby food. it just does spammy things like that.
also good for you for using data
and plus, it doesnt really affect anything to your personnaly, other than show you stuff you might like depending on things you look up (pets, cooking, etc)
