SMS Consent Process

10DLC Compliance Documentation

Overview

Siren is an incident management and on-call alerting platform. Incident alerts are delivered via voice calls. Users may optionally opt-in to receive SMS notifications for on-call schedule reminders and other non-incident notifications. All SMS messaging requires explicit opt-in consent from users.

User Opt-In Flow

Users provide explicit consent for SMS notifications through two pathways:

1. Onboarding Flow (New Users)

During account setup, users are presented with a clear choice to add a phone number for voice call alerts and optional SMS notifications. The process includes:

Onboarding Step 1: Phone number opt-in choice

Step 1: Users choose to add phone number or skip (phone number is optional)

Onboarding Step 2: Phone number entry and consent

Step 2: Explicit consent checkbox with full disclosure

Onboarding Step 3: Phone verification

Step 3: SMS verification code sent to confirm number

2. Account Settings (Existing Users)

Users can add or remove their phone number at any time through account settings:

Settings: Phone number entry and consent

Settings: Same consent process available in user settings

Settings: Verified phone number status

Verified: Users can remove their number at any time

Consent Language

Before enabling SMS notifications, users must check a consent box that clearly states:

"I agree to receive SMS messages from Siren related to my on-call schedule and other Siren events. Message and data rates may apply. Reply STOP to opt-out or HELP for assistance."

Additional context provided: "You'll receive SMS notifications from Siren for on-call schedule reminders and other non-incident notifications. Message and data rates may apply. Reply STOP to cancel or HELP for assistance."

Message Frequency

SMS messages are sent for on-call schedule reminders and non-incident notifications. Frequency varies based on:

  • User's on-call schedule (weekly or daily rotations)
  • Whether schedule reminder notifications are enabled
  • Account and service-related updates

Typical usage: 1-5 messages per week, primarily for shift reminders.

Opt-Out Process

Users can opt-out of SMS notifications in two ways:

  1. Reply STOP: Users can reply "STOP" to any SMS message to immediately unsubscribe
  2. Remove in Settings: Users can remove their phone number from account settings at any time

Both methods immediately stop all SMS notifications. Users receive email notifications instead.

Use Case: Schedule Reminders and Notifications

SMS notifications are used for non-incident communications:

  • On-call shift starting reminders
  • Schedule change notifications
  • Account and service updates

Note: Critical incident alerts are delivered via voice calls, not SMS. We never send marketing messages or promotions via SMS.

Privacy & Data Protection

All phone numbers are:

  • Encrypted at rest in our database
  • Used solely for incident notification delivery
  • Never shared with third parties
  • Deleted immediately upon user request
