2::Only my Internet Service Provider knows what I did.
1::Yes, no one is able to know what I did online.
3::Private browsing only protects me from people with physical access to the computer.

This is partially the correct answer. Private browsing offers you privacy from people with physical access to your computer. Many organisations including your Internet Service Provider (ISP) and also the providers of the web pages you visit (e.g. social networks) are still able to know what you did online. Note also that if someone is sitting on the same local network as you, he/she can intercept your unencrypted traffic – via an appropriate software.

This is the correct answer. Private browsing offers you privacy at the local level only. Many organisations including your Internet Service Provider (ISP), but also the providers of the web pages you visit (e.g. social networks), are still able to know what you did online. Note also that if someone is sitting on the same local network as you, he/she can intercept your unencrypted traffic – via an appropriate software.


Web browsers normally store browsing history, web pages visited, images, videos etc., within the browser’s cache. However when private browsing is enabled, the browser history is no longer stored in the cache, and cannot be recovered.

However, does private browsing fully ensure that no one is able to know what you did online?
