If you completed an identity check while signing a document through Rox Register, you can ask for the raw identity captures (ID images, selfie frames) to be deleted. Confirm the email address or mobile number you signed with; the request then goes to the organisation that sent you the document, which decides on it under its legal obligations.
What is deleted: the raw identity captures. What stays: the signed document, its completion certificate and the sealed cryptographic hashes, which contain no readable personal data and keep the signature verifiable.
