Unless a longer retention period is required or permitted by law, we will only hold your personal information on our systems for the period necessary to fulfil the purposes outlined in this Privacy Policy or until you request it is deleted. If, having registered for any of our Services, you do not use them for a reasonable time (which may vary depending on the Service(s) you’ve registered for) we may contact you to ensure you’re still happy to receive communications from us. Even if we delete your personal information it may persist on backup or archival media for legal, tax or regulatory purposes.
