Cookies?

Cookies are so delicious.
I like them so much.
However, I come across a lot of cookies on the website.
To tell the truth, such kind of cookies, I do not like.
So I do not accept it.
Cookies are very convenient when we go online shopping.
It helps us to keep holding goods in the cart.
On the other hand, cookies track our browsing habits and collect personal data, which may be used for targeted advertising or sold to the third parties.
How risky it is!
We should not always accept cookies.
Right?
