The WordPress Blog does not store cookies on readers' browsers, unless those readers have created a log-in to the blog, which readers usually do not, just by reading the blog. Log-ins would only be useful, if other people were to contribute and post articles. Leaving a comment is not an example, of what requires a log-in. In the event of a successful log-in, the information stored in the cookie is limited to that log-in. Additionally, this blog does not collect any personal data, nor store any personal data about each reader. - Dirk Mittler
