SMS / Transactional Messaging Notice

How Knock Knock uses transactional texts for queue, account, and session updates.

Effective date: 2026-06-17

Transactional Messages Only

Knock Knock uses SMS for transactional messages related to queue progress, session readiness, account access, security, and support operations.

These messages are transactional and operational, not promotional marketing texts.

  • Message frequency varies by activity.
  • Message and data rates may apply.
  • Opting out may reduce or disable important service functionality.
  • If STOP or similar keywords are supported in product messaging later, the notice and UI copy must stay consistent.
