From time to time, we sometimes make changes in the way we do business online for various reasons, and sometimes without knowing. However, when it affects our customers who visit and use our website, they need to know of these changes.
Basically, these documents protect you and the visitor of your site providing them with information on how you conduct business, how you expect the visitor to use the site and how you intend to protect the privacy of their information that you might obtain.
You may also want to state that “future changes may occur without notice and that it is the user’s responsibility to periodically check for any changes that may have occurred.”
But as you know we’re all about “Customer Service” so it would make good business sense to send an email to your customers indicating (in the subject line) a “Change of Policy” statement.
