ISP tracking: what your provider sees and how a VPN hides it

Destinations, times and data volume

Your provider cannot read encrypted pages, but it can track which sites and services your household uses, when, and how much data they move. You can limit that with encrypted DNS and your provider's advertising opt-out; a VPN key hides the destinations as well.

None of these steps hides the fact that you are online, and none of them needs to. The point is to decide who learns which services your household uses.

Visible to your ISP without a VPN

• Domain names your devices look up, unless DNS is encrypted.
• The servers each device connects to and the times it does so.
• The amount of data, which shows whether you were streaming, gaming or downloading.
• Unencrypted traffic from older gadgets such as some smart TVs and cameras.

Visible with a VPN key on

• One encrypted connection from your home to a VPN server.
• How much data goes through it and when.
• Nothing about the sites, apps or services inside.

What the FTC found in 2021

The FTC studied six large providers, including AT&T Mobility, Verizon Wireless, Charter, Comcast, T-Mobile and Google Fiber. Its staff report, published in October 2021, found that many of them collect more data than customers expect, combine browsing and app data with other information to target ads, and offer few meaningful choices to limit that use. It is a useful read if you want to know what your own provider's privacy policy is likely to cover.

When you read your own provider's policy, look for three things: whether it uses browsing or app data for advertising, whether it shares that data with partners, and where the opt-out lives. Some providers put the opt-out in the account app, others on a separate privacy page, and it often needs to be set per account rather than per device.

Ways to limit tracking

• Turn on encrypted DNS in your browser or phone settings.
• Opt out of your provider's advertising or data-sharing program in your account settings.
• Use the VPN key on devices where you want destinations hidden.
• Replace or update gadgets that still send unencrypted data.
• Check the router settings: some provider routers have their own data-collection options.

What stays visible even with a key

A VPN does not make you anonymous. Your provider still knows you are its customer and when you are online, and sites you sign in to know who you are. The VPN service sees the destinations instead; ViewPoint VPN keeps no logs of them, and that is the trust you are moving rather than removing.

Mobile data works the same way. Your carrier is the provider there, so the same visibility applies when your phone is off Wi-Fi, and the same key covers it.
