Retention
Contact messages are kept only as long as needed to handle the request and any related follow-up, and are then removed. A question about a vitamin D article is not held on file for the sake of it.
Technical logs are retained for a limited period for security and troubleshooting. If you ask for deletion, we remove your message and address unless we are required to keep a record for a legal reason — a legal reason would be explained to you in writing.
