SMS Proof of Consent

Effective Date: May 5, 2026 · Last Updated: May 5, 2026

This page documents how NovaGuard Technologies, Inc. (“NovaGuard,” “we,” “our,” or “us”) obtains express written consent from end users before sending SMS/MMS text messages related to the Constant Guardian® platform. It is provided for transparency to customers, end users, and messaging carriers (including Twilio) reviewing our messaging program.

1. Program Overview

• Program Name: Constant Guardian Alerts & Notifications
• Brand / Sender: NovaGuard Technologies, Inc.
• Sending Number: 1-833-322-7354 (Toll-Free)
• Message Types: Security and incident alerts, system status updates, and operational notifications related to the Constant Guardian OT/ICS network monitoring platform.
• Expected Frequency: Approximately 1–5 messages per week per subscriber. Frequency may vary depending on the volume of security events detected at the subscriber’s monitored sites.
• Cost: There is no charge from NovaGuard for these messages. Standard message and data rates from the subscriber’s mobile carrier may apply.

2. How & Where Consent Is Collected

Consent is collected exclusively within the authenticated Constant Guardian product environment. Only authorized users of a customer’s Constant Guardian account — after they have logged in — can enroll in SMS notifications. No SMS opt-in is collected from this public website, and phone numbers are never purchased, rented, or imported from third-party lists.

The opt-in is entirely user-initiated:

1. The user logs into the Constant Guardian web dashboard or mobile application.
2. The user navigates to Account Settings → Notifications → SMS Alerts.
3. The user enters their mobile phone number.
4. The user reads the disclosure text shown below and actively checks an unchecked-by-default consent checkbox.
5. The user clicks “Enable SMS Alerts” to submit the request.
6. NovaGuard sends a one-time verification code to the supplied number, which the user must enter back into the dashboard to confirm ownership of the device.
7. Only after successful code verification is the number enrolled and a welcome message sent.

3. Opt-In Screen Mockup

The screen below is a faithful reproduction of the SMS enrollment screen presented to users inside the Constant Guardian product. The consent checkbox is unchecked by default and the “Enable SMS Alerts” button is disabled until the user actively checks the box.

7. Recordkeeping

For every opt-in, NovaGuard records and retains the following evidence of consent for at least the duration of the subscription plus four (4) years:

• The user account ID under which consent was given;
• The mobile telephone number enrolled;
• The exact disclosure language displayed at the time of consent (versioned);
• The timestamp (UTC) of the checkbox interaction and the form submission;
• The IP address and user-agent string of the device that submitted the opt-in;
• The timestamp (UTC) of successful verification-code entry; and
• Any subsequent STOP, START, or HELP keyword events.

8. No Sharing of Mobile Information

Mobile information (including phone numbers and SMS opt-in data) is never shared with third parties or affiliates for marketing or promotional purposes. Phone numbers are used only to deliver the messages described in this document. Limited operational sharing with our messaging service provider (Twilio Inc.) is required solely to transmit the messages and is governed by Twilio’s own data-protection commitments.
