I don't know if this topic has already been covered. In any case, incognito VPN is fantasy. In many cases.
Personally - I like Winscribe and use it, but I know that the headquarters is in Canada. The privacy is the same as in the USA - none. Eset also uses it.
Its advantage is that if I need to use Windscribe in the free version, I can choose a server in several countries in the world.
Bitdefender has Hotspot Shield from the USA and also zero privacy. As if Romanians couldn't choose a better solution...? Let me remind you that HotSpot Shield has already had some mishaps.
I use Proton VPN Free. I trust them the most. So far.
In addition, I have information from many sources that it may not be perfect in terms of operation, but when it comes to privacy, MullVad (Sweden) is very good.
And many trusted people have used Fsecure so far. In my country, security portals recommend it, including the main owners of these portals. Until now, because now the question is what will happen after switching to Avira.
Fsecure is one of the few that is transparent and does not hide anything that it collects.
The rest only lie that it does not collect logs, etc. This is nonsense.
VPN has become a business.
