A cookie question?

Question

You have placed an ad in a website using a form. Your e-mail appears in your ad. When you delete all of your temporary files, including "cookies", does your e-mail get deleted from your ad so that it becomes impossible for the site to contact you by e-mail? You signon again with your e-mail if the site uses your e-mail to signon and restore it. What happens if you don't use your e-mail to signon? Please answer only if you know about computers well.

Answer 1

No. When you place your web ad using the form, it has nothing to do with cookies. Your ad will have the email address you placed on it until you, or someone that has admin rights of the web site changes it.

Now related to signon, yes, signon can use cookies to save your username and password. If your username is your email address as is typically the case then yes, the cookie will store your email address and re-input that information for you when you return to the site, if you keep that cookie and allow it to run on your system.

What do cookies do and how do they work?
A cookie is merely a text file that a web site creates to help either you or the site do something. The text file can be something as simple as, when you visited the site last, it can be storing your username and password, or it can be very complex and store as much or more than: your username, your real name, your password, your os, your ip address, your browsing history for the site the cookie was created for, where you go when you leave the site, where you were just before you came to the site and a myriad of other things you may or may NOT want others to track.

I delete my cookies and use information very often. I close my browser and delete my cookies and use history IMMEDIATELY after any and ALL online transactions that involve finance or personal data in any way. I never visit a site that is related to my finances from a link, I always type the site's URL in manually. I store my usernames and passwords in a text file on a USB firefly drive in encrypted format which requires a password to unlock and remove that firefly when I am not using it. That firefly drive stays where I feel it's safe.
