You place the image link and the only thing you have access to is the count, though there is always data about your visitors being captured. If you ever decide to upgrade to the Pro version, which is just $12 per year, you can see all the data that your counter grabbed. When you upgrade to the Pro version, you will associate your email with the counter. So there is no "password" requirement. If you go to change the text or colors of your counter, and you enter an email that isn't associated with the counter, it will just display an error message that your email address and this counter don't match. You will get an email with the counter ID and your email association. If you want to change the color or text at any time, you just come to "home base", enter in your counter ID and email, and change it through there. As for the "tracking" of emails, it's a service I use to send emails. That tracking data isn't actually used for anything.
