Users can accept your terms and conditions outside the system, but TutorCruncher will not have any way of verifying this automatically. An Administrator can record this manually by navigating to the user's profile and selecting the eye symbol next to the 'Data storage consent' field. Doing this will record that consent has been given to your company's terms and conditions.
Recording consent on a Client's profile.
Note: The 'Data storage consent' field only appears on a user's profile if terms and conditions have been set for that user's audience. If you cannot see the field, check that terms have been saved for the relevant audience under System > Settings > Company Details > Terms and Conditions.
