# User Consent configuration

#
# Parts of this section are required if enabling the 'consent' resource under
# 'listeners', in particular 'template_dir' and 'version'.
#
# 'template_dir' gives the location of the templates for the HTML forms.
# This directory should contain one subdirectory per language (eg, 'en', 'fr'),
# and each language directory should contain the policy document (named as
# '<version>.html') and a success page (success.html).
#
# 'version' specifies the 'current' version of the policy document. It defines
# the version to be served by the consent resource if there is no 'v'
# parameter.
#
# 'server_notice_content', if enabled, will send a user a "Server Notice"
# asking them to consent to the privacy policy. The 'server_notices' section
# must also be configured for this to work. Notices will *not* be sent to
# guest users unless 'send_server_notice_to_guests' is set to true.
#
# 'block_events_error', if set, will block any attempts to send events
# until the user consents to the privacy policy. The value of the setting is
# used as the text of the error.
#
# user_consent:
#   template_dir: res/templates/privacy
#   version: 1.0
#   server_notice_content:
#     msgtype: m.text
#     body: >-
#       To continue using this homeserver you must review and agree to the
#       terms and conditions at %(consent_uri)s
#   send_server_notice_to_guests: True
#   block_events_error: >-
#     To continue using this homeserver you must review and agree to the
#     terms and conditions at %(consent_uri)s
