Terms of Service

Last updated: April 2, 2026

1. Agreement to Terms

By accessing or using Signals’ services (“Service”), you agree to be bound by these Terms of Service (“Terms”). If you disagree with any part of these terms, you may not access the Service.

2. Definitions

  • “Customer” means the business entity that registers for and uses the Service.
  • “Customer Personal Data” means data that Customer provides to Signals or that is generated through the Service on Customer’s behalf, including order data, end-customer contact information, and conversation content. Customer Personal Data does not include data that has been aggregated or de-identified so that it can no longer reasonably identify a natural person.
  • “End Customer” means a consumer or other individual with whom Customer interacts through the Service.

3. Description of Service

Signals is a proactive customer support platform. We reach out to customers via SMS and other channels, hold real two-way conversations powered by AI, and resolve issues before they escalate. The Service includes proactive outreach, conversational AI, human escalation, product feedback collection, exchange facilitation, and analytics derived from customer interactions.

4. Business-to-Business Service

Signals is a business-to-business (B2B) service intended exclusively for use by businesses, enterprises, and professional entities. This Service is not intended for consumer use or personal, household, or family purposes.

4.1 Geographic Availability

The Service is currently available only to businesses located in the United States. The Service is not offered to businesses or individuals located in the European Union, the European Economic Area, or the United Kingdom.

5. Confidentiality, Ownership, and Data License

5.1 Confidentiality

Each party agrees to protect the other party’s proprietary and confidential information using at least the same degree of care it uses for its own confidential information (and not less than reasonable care), and not to use or disclose it except as necessary to perform under these Terms. This obligation survives for five (5) years after disclosure. Standard exceptions apply (information in the public domain, information known prior to disclosure, independent development, and disclosure required by law).

5.2 Ownership

Customer owns all right, title, and interest in its Customer Personal Data and order data. Signals owns the Service, the platform, all improvements, and all related intellectual property.

5.3 Data License

Customer grants Signals a non-exclusive, perpetual, irrevocable, royalty-free, worldwide license to use Customer Personal Data and order data derived from the Service to improve, develop, and enhance Signals’ products, offerings, technologies, and algorithms. To the extent such data is used for these purposes, Signals will use commercially reasonable efforts to aggregate or de-identify the data so that it does not identify Customer or its End Customers. Customer represents and warrants that it has obtained all necessary consents and rights from its End Customers to grant this license.

7.1 SMS Compliance

The Service sends SMS messages to End Customers on Customer’s behalf. Customer represents and warrants that it has obtained all consents required under the Telephone Consumer Protection Act (TCPA), applicable state laws, and any other relevant regulations before providing End Customer contact information to Signals for outreach. Customer shall indemnify Signals against any claims arising from Customer’s failure to obtain such consents.

8. Data Processing and Privacy

Your use of our Service is also governed by our Privacy Policy. By using the Service, you consent to:

  • The collection and use of information as outlined in our Privacy Policy

9. Intellectual Property Rights
