Where to share your data

Duration of data storage.

When you leave a comment, the comment and its metadata are retained indefinitely. This is so that follow-up comments can be recognised and approved automatically, instead of keeping them in the moderation queue.

If a user registers on this site, we store the personal data they have provided on their user profile page. All users can view, edit or delete their personal information (but cannot change their username). The site administrator can also view and edit their information.

Your rights to your data

You can also make a request to have your personal data erased. This does not include data that we are obliged to retain for administrative, legal or security purposes.
