This can only be completed on by the SIMS Online Services admin via admin.sims.co.uk
Go into to the SIMS Parent Settings > Data Collection
There will be a list of 8 data areas that are collected:
These are all linked to the areas of the same name in SIMS Parent. The only exception being Student Details which also controls whether Addresses and Telephones & Emails can be edited also.
The areas are then removed by selecting the cross next to each of the data areas.
