Cookies are small text files that are stored on your computer.
When visitors leave comments on the site data shown in the comments form is collected, and also the visitor’s IP address and browser user agent string to help spam detection.
If you leave a comment, the comment and its metadata are retained indefinitely. This is so follow-up comments can be recognised and approved automatically instead of holding them in a moderation queue.
If you have left comments, you can request to receive an exported file of the personal data held about you, including any data you have provided. You can also request that I erase any personal data held about you. This does not include any data that is needed to be kept for administrative, legal, or security purposes.
When commenting you have the option to get notified by email about follow-up blog comments or future posts, if you change your mind you can unsubscribe using the link in the email. You can also like comments and posts where some data is saved such as your WordPress.com user ID and IP address.
Another plugin this blog uses is an anti-spam plugin called Antispam Bee, when a visitor leaves a comment it will check that the IP address is valid. No private user data is saved by this plugin.
