I tend to use my debit card while online shopping and I was wondering if there is any possibility of hacking or leaking of crucial information.
The connection between you and your bank or the merchant should have its own encryption anyway (TLS). If it doesn’t, that’s what you should be worried about, not your VPN. I’m failing to see the problem here.
Yes, it is safe. All traffic is encrypted and routed through ProtonVPN servers, which are full disk encrypted.
As opposed to not using a vpn?
This is what it is important. Obviously VPN might help you in someway, but that is not a silver bullet.
well, yes. either that or any other VPN.
Definitely better than no vpn. Compared to others I think they are very good but honestly it just comes down to trusting the provider you choose.
