Privacy Policy

Effective date: October 1, 2026

Third Coast Systems (“Third Coast Systems,” “TCS,” “we,” “us,” or “our”) provides Line Two, a missed-call text-back and customer-intake service for local service businesses.

This Privacy Policy explains what information we collect, how we use it, and how we protect information related to our messaging services.

Information we collect

When you call, text, or otherwise interact with Third Coast Systems or a business using Line Two, we may collect information such as:

• your phone number and caller ID information
• your name, if you provide it
• your service address, if you provide it
• details about the service issue or request you describe
• preferred timing or availability, if you provide it
• SMS and call metadata, including timestamps and delivery status
• consent and opt-out records
• messages, photos, or other information you voluntarily send through the service

We may also collect basic technical and operational information needed to operate, secure, troubleshoot, and improve Line Two.

How we use information

We use the information we collect to:

• respond to customer inquiries
• provide missed-call text-back and customer-care messaging
• collect and organize service-request details
• route relevant information to the appropriate business or service provider
• provide customer support
• maintain consent, opt-out, and messaging records
• operate, secure, troubleshoot, and improve Line Two
• comply with applicable legal, regulatory, and carrier requirements

Line Two may use automated language-processing technology to understand customer messages, organize information, and assist with intake. Automated systems are used to support the customer-care workflow and are not intended to provide professional trade advice or diagnoses.

SMS and mobile information

We do not share, sell, rent, or provide your mobile phone number, SMS opt-in information, or messaging consent to third parties or affiliates for marketing or promotional purposes.

Mobile information and messaging consent are used only for the messaging program and customer-care purposes for which consent was provided.

We may use service providers that process information on our behalf solely to operate Line Two, such as communications, hosting, infrastructure, and technology providers. These providers may process information only as necessary to provide services to us and are not authorized to use SMS opt-in information or mobile information for their own marketing or promotional purposes.

If you are communicating with a business through Line Two, information you provide may be shared with that business as necessary to respond to your service request. This service-request sharing does not transfer your SMS opt-in data or consent to that business or authorize its own messaging program.

Messaging terms

By affirmatively opting in to receive text messages from Third Coast Systems, you may receive customer-care messages related to your inquiry.

Message frequency varies. Message and data rates may apply.

You may reply STOP at any time to opt out of further messages.

You may reply HELP for assistance.

Data retention

We retain information for as long as reasonably necessary to:

• provide and support Line Two
• maintain business and consent records
• resolve disputes
• enforce agreements
• comply with applicable legal and regulatory requirements

Retention periods may vary depending on the type of information and how it is used.

Data security

We use reasonable administrative, technical, and operational safeguards intended to protect information against unauthorized access, misuse, loss, or disclosure.

No system can guarantee absolute security, but we work to limit access to information to systems and service providers that need it to operate the service.

Your choices

You may opt out of SMS communications at any time by replying STOP.

You may request assistance by replying HELP.

You may also contact Third Coast Systems regarding questions about your information, or to request access, correction, or deletion where applicable.

Children’s privacy

Line Two is intended for use in connection with business and service inquiries and is not directed to children under 13. We do not knowingly collect personal information from children under 13 through the service.

Changes to this Privacy Policy

We may update this Privacy Policy as Line Two evolves or as legal, regulatory, carrier, or operational requirements change.

When we make changes, we will update the effective date shown above.
