Explain it then.
Also, this: Why you need VPN with porn | My Private Network VPN
Lol they focus more on incognito window(you should use it though)but VPN is not required because google doesn’t show you ads from your porn watching habits and if google started doing those then no one would use them.
Note :- That site is tying to sell their VPN.
If you have more doubts feel free to pm.
I don’t. There are multiple porn sites out there and you can’t personally vouch that they used the same advertisements so you can’t 100% say they won’t gather your data. Even so, they make good points and there are free alternatives.
