Not all search engines collect your personal information like google does. Some search engines never collect your personal information.
This is my personal message to you.
I say this to all my friends and family who I care about. I am not getting paid for this. I have a strong opinion on this as a web developer.
I will make it short. If you want to know more about it, please search for it.
How much privacy are you willing to give up? That's the question. It's OK to use Google if you feel OK about it. Because they don't mean harm.
But, if you don't like the idea of google knowing everything about you until you die, use www.DuckDuckGo.com.
