Can the owner of the WiFi see what you do?

Yes, definitely. A WiFi owner can see what websites you visit while using WiFi as well as the things that you search on the Internet. There are lots of routers with a built-in tracking feature from companies like Netgear.

Can home WiFi owner see what sites I visited incognito?

Incognito mode, or private browsing, is a special feature where the browser will not keep data from the website. This is why you cannot see the sites you visited in your history and address bar after using incognito mode. These files are cookies, browsing data, saved form data, and saved passwords.

Does resetting a router delete the history?

NO! A reset wipes out configuration information and returns the router to factory defaults. Do not reset your router unless you know how to configure it and have a record of the configuration information, e.g. admin password, SSID, and so on (see rest of the article for more details).

Does your ISP know what you do on the Internet?

Everything you do online, goes past your ISP. This means they automatically receive a lot of information about you and your online life. As long as your online data isn’t sufficiently encrypted, your ISP will see it all. Even the incognito mode doesn’t keep you safe.

Can people see what you’ve done on your cable Internet?

This is only partly the case: contrary to Wi-Fi, a cable connection doesn’t allow everyone to look into your online activities. But there’s still someone who could: the administrator of your network will be able to see all of your browser history. This means they can retain and view almost every webpage you’ve visited.

Can other parties on the Internet see my IP address?

Other parties on the internet will not see your own IP address any longer, but will see the IP address of the VPN server. This way all your online searches and website visits cannot be traced back to you.

Can my ISP see my encrypted WhatsApp messages?

It might be nice to know that encrypted data, such as WhatsApp messages locked behind end-to-end encryption, aren’t visible to your ISP. If you live in the EU and want to know what data your provider has collected on you, the GDPR gives you the right to ask for a full report.
