1. Introduction

Signetik, LLC ("Signetik," "we," "us," or "our") operates an IoT device monitoring SMS notification service. This Privacy Policy describes how we collect, use, and protect the personal information you provide when you opt in to receive SMS messages through our Signetik Device Monitoring program.

• The serial number of the device associated with your opt-in

We do not collect your name, address, payment information, or any other personal data through this SMS opt-in process.

3. How We Use Your Information

The information collected is used solely to:

• Send automated SMS text messages regarding the status and fault conditions of your registered IoT device
• Maintain a record of your consent in compliance with applicable telecommunications regulations (TCPA, CTIA guidelines)
• Process opt-out (STOP) requests and maintain suppression records

4. Message Frequency

Message frequency varies based on your device's operating conditions. Under normal circumstances, you may receive 1-4 status messages per day. On days where a fault condition is detected, you may receive up to 10 messages. Signetik does not send marketing or promotional SMS messages through this program.

• As required by law, court order, or regulatory compliance obligation
• In connection with a merger, acquisition, or sale of Signetik's business assets, with appropriate notice

6. Data Retention

Your phone number and opt-in record are retained for as long as you remain subscribed to the SMS service, plus a minimum of three (3) years following opt-out to satisfy regulatory record-keeping requirements. You may request deletion of your data by contacting us as described in Section 9; note that regulatory retention requirements may limit our ability to immediately delete certain records.
