Go to Koha administration > Global System Preferences and search for privacy policy.
No request to consent to a privacy policy will be enabled on the site.
A request to consent to a privacy policy will appear on the OPAC site, but it will not be mandatory.
It will be mandatory for users to consent to a privacy policy before they can use the OPAC site.
When this system preference is enabled a field requesting the user consent to a privacy policy will appear at the bottom of the OPAC self registration and on the user account on the OPAC.
Navigate to the self registration form by clicking Log in to your account on the OPAC. This will bring up a popup box with login options and a link to Create an account.
If the PrivacyPolicyConsent is set to Permissive consent will be requested, but it will still be possible to complete self registration without agreeing to the privacy policy.
Once these system preferences have been enabled, when an existing patron logs into the OPAC they will automatically be brought to their own record and will be asked to consent to the privacy policy.
If PrivacyPolicyConsent is set to Permissive patrons will be able to continue without selecting Yes. If a user selects No their preference will be saved but they will not be logged out.
Patrons are able to view and change their response to this query in the your consents tab on their account. 
If the PrivacyPolicyConsent is set to Enforced and a patron changes their answer to No in the Consents tab they will automatically be logged out. If they try to login again after changing their answer, they will be presented with the same consent screen and if they pick Yes they will be able to continue logged in but if they pick No they will be logged out again.
If PrivacyPolicyConsent is set to Permissive and a patron changes their answer to No in the Consents their choice will be saved but they will not be logged out.
