Consent Mode Selection

When to Use

Choose consent mode based on your site's regulatory requirements and user experience priorities. Configure at Administration > Configuration > User interface > Klaro! > General (Consent section).

Decision

If you need... Use... Why
No visible notice (minimal friction) Silent mode Blocks external resources but shows no dialog
Informational notice allowing page use Notice dialog Non-modal notice visible while site usable
Force acknowledgment before site access Notice dialog as modal Modal blocks interaction until dismissed
Granular service choices required Consent dialog modal Full service list; blocks site until decision
Post-decision preference changes Toggle button (any mode) Floating button to reopen consent dialog

Pattern

Silent Mode (default, minimal intervention): 

consent_mode: silent
toggle_button: true  # Users can still access dialog via button
# Result: No dialog shown, external resources blocked with placeholders

Notice Dialog (informational approach): 

consent_mode: notice_dialog
toggle_button: true
accept_all_notice: false  # Only accept required services on quick accept
# Result: Non-modal notice; users can browse while visible

Modal Consent (GDPR-compliant strict approach): 

consent_mode: consent_dialog_modal
toggle_button: true
buttons:
  accept_all: true
  decline_all: true  # Equal prominence required for GDPR
  close_button: true  # Mandatory in some jurisdictions
# Result: Full service list in modal; site blocked until decision

Common Mistakes

  • Wrong: Using Silent mode for sites requiring explicit consent → Right: Upgrade to Notice/Modal mode for GDPR compliance
  • Wrong: Omitting toggle button → Right: Users have no way to modify preferences later; violates GDPR withdrawal right
  • Wrong: Accepting all services in Notice mode → Right: Set accept_all_notice: false to only enable required services
  • Wrong: No decline button in consent modal → Right: Dark pattern violation; always include equal-prominence decline option
  • Wrong: Forgetting close button → Right: Mandatory in some EU countries; configure close_button: true
