A feature of many web browsers that allows the user to prevent any data (like history, cookies
, or the cache
) from being stored while it is on. Also known as porn mode
for really obvious reasons, but may be used whenever any sensitive/confidential information is going to be transmitted.
Private browsing is more comprehensive than simply erasing the history, because that's just a list of URL
s, and browsers also save things like cookies (for sites to remember you) and images in the cache (to load faster later).
Private browsing is just a browser feature — there are other ways visited sites are tracked (for example, by your Internet provider), so it's not foolproof.
Say you are about to purchase a surprise for someone. If you choose a private browsing session, after you're done, other people won't see what gift you bought, or your credit card number, or your drug trafficking, or your porn.
