This is a tracking tool, not legal advice. It calculates the standard statutory response window - one calendar month from receipt, or three months total for a request you've flagged as extended for complexity - as a guide only, and separately tracks whether you've told the requester about an extension within that first month (a distinct obligation from the extended deadline itself). It does not verify identity, manage your underlying data, or decide what counts as "complex" or "manifestly unfounded" - those are your judgement calls. Always check current ICO guidance for your specific case.
