If you leave a comment, the comment and its metadata are stored indefinitely. This is so we can recognize and approve any follow up comments automatically instead of keeping them in a moderation queue.
For people that register on our site (if any), we also keep the personal data they give us in their user profile.
All users can see, edit, or erase their personal information at any time (except they cannot change their username).
Website admin can also view and update those details.
