VPN Provider
Your Internet Service Provider has the power to see information about the websites and data services you access while using their modem. While they cannot see the data being transmitted, they can see the servers you connect to. This is often used to build user profiles for targeted advertising or enforcing copyright law on peer-to-peer traffic.
Aggregation
We can lessen this by creating a private, encrypted tunnel to a VPN server connected elsewhere in the world. This will not provide total anonymity, but it can help obscure your traffic and make it harder to tell your traffic from other clients.

Behind a Virtual Private Network, your ISP can see that you've connected to a remote server but the traffic between is encrypted. Your web data is aggregated with other users to make your traffic less traceable back to you. This can also channel your Internet traffic to a specific geographic region.

If you're looking for additional privacy from your internet service provider – such as downloading files with qBittorrent or obscuring your AdGuard Home lookups – then a VPN service could be an option. Gluetun can connect individual containers to your VPN allowing you to circumvent geo-restrictions by changing your location – such as a MeTube server that can access Swedish internet content.

Privacy Assurance
Not all VPNs are created equal and they have the same opportunities to snoop on your data just like your ISP. They may store logs and submit them to law enforcement agencies when asked. If they don't follow industry practice, they may have their databases hacked. Some providers have been implicated in data collections for government surveillance purposes. Others use your data to build user profiles they can sell to brokers.
VPN providers can, however, volunteer for third-party audits to ensure consumer privacy and build community trust. Privacy Guides is a non-profit that educates about personal privacy and independently reviews service providers. They recommend Proton VPN, Mullvad, and IVPN services.
