How feedback data is protected

New feedback records are designed to avoid cleartext storage of sensitive technical identifiers.

The admin backend can block a feedback source by hash without needing to keep the original IP address in cleartext.

The public website is intended to avoid non-essential tracking cookies.

Admin areas may use necessary session cookies for login, CSRF protection and basic security. These are required for the admin backend to function.

If analytics, advertising or other non-essential cookies are added later, this page should be updated before they are enabled.
