Once a study is complete, we recommend performing the following actions:
1) Lock all records
2) Export a copy of the study data
3) Set the study to 'not live' in the 'Settings' tab.
4) Remove all users and study admins can reduce their own rights.
It recommended that study admins leave themselves as the only user, and remove all user rights except 'View', 'Export' and 'Manage Records'.
In accordance with GCP rules, all data is stored by default for 15 years on the Castor servers at no additional cost to users.
