Effective date

The date on which this record or notice becomes operative. On a ConsentRecord, it may be later than signed_date (the day the data subject indicated consent) and later than created_at (the digitisation timestamp); for paper workflows, signed_date is the day of the paper signature and effective_date is typically the same day but may be delayed by program logic. On a PrivacyNotice, it is the date from which this notice version applies; records collected before this date reference the superseded version via supersedes_ref.
