If you’re using the calculator on a personal basis (i.e. about your criminal record, or that of a family member/friend) then you do not have to set up an account.
If you wish to use the calculator as a professional or organisation as part of your work, you should set up a multiple-use account.
The calculator operates using the rehabilitation periods as they apply in England & Wales. If you live in Scotland, you may want to seek advice from Disclosure Scotland (although they may be limited in what advice they can give, as an Executive Agency of the Scottish Government, and in Northern Ireland, you may want to seek advice from NIACRO.
It might not always be as obvious as where you live when it comes to deciding which rules apply. See our detailed guidance on the ROA for more information.
