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.
This blog also uses an anti-spam plug-in 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 plug-in.
