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 or use the Service.
Signals is a customer messaging platform for ecommerce brands. The Service supports customer conversations over iMessage, RCS, SMS, 10DLC SMS, WhatsApp, and related channels. The Service may include AI-assisted replies, human-sent replies for CX escalation, customer AI agent messages through Signals MCP, order support, delivery support, returns and exchanges, product and policy answers, customer-initiated purchase assistance, review workflows, optional brand-initiated marketing sends, analytics, and integrations with commerce, support, messaging, consent, fulfillment, warehouse, and return systems.
Signals’ core service is customer support and responding to user-initiated queries. Customers may use Signals solely for support and customer-initiated conversations. Optional marketing workflows are subject to separate consent and eligibility controls.
Signals is a business-to-business service intended for businesses, enterprises, and professional entities. The Service is not intended for personal, household, or family use.
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.
Customer is responsible for:
Customer represents and warrants that it has obtained all rights, permissions, notices, and consents required for Customer’s selected use of the Service, including under the Telephone Consumer Protection Act (TCPA), applicable state laws, carrier rules, messaging platform rules, WhatsApp rules, 10DLC rules, and any other applicable regulations.
Customer is not required to enable unsolicited marketing sends to use Signals. For SMS, 10DLC SMS, and RCS marketing sends, Customer must obtain explicit written consent before such sends occur. For iMessage and WhatsApp marketing sends, Customer must provide any consent required by applicable federal law, state law, platform rules, and Signals’ operating policy. Where written marketing consent is not available, Signals’ marketing-send eligibility controls limit brand-initiated marketing to confirmed iMessage conversations with no restricted-state signal. Signals’ current public operating policy is described on the Messaging Compliance page.
When Customer or its personnel, systems, or agents send, initiate, or cause messages through Signals, including through the dashboard, API, or MCP connector, Customer is responsible for the compliance of those messages. This includes the message content, purpose, timing, recipient selection, consent basis, suppression status, and any required disclosures.
Customer may not use rented, sold, purchased, scraped, or shared opt-in lists with Signals. Customer must keep connected consent and suppression systems accurate, including systems such as Shopify, Listrak, and other commerce or messaging consent tools used by Customer.
Customer shall indemnify Signals against claims, damages, penalties, losses, and expenses arising from Customer’s failure to obtain required consent, Customer’s messaging instructions, Customer’s data, or Customer’s violation of applicable messaging laws or platform rules.
Customer agrees not to use the Service to:
Use of the Service is governed by our Privacy Policy. By using the Service, Customer authorizes Signals to:
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. Each party agrees not to use or disclose confidential information except as necessary to perform under these Terms. This obligation survives for 5 years after disclosure. Standard exceptions apply, including information in the public domain, information known before disclosure, independently developed information, and disclosure required by law.
Customer owns all right, title, and interest in Customer Personal Data. Signals owns the Service, platform, software, models, workflows, improvements, documentation, and related intellectual property.
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 it does not identify Customer or End Customers. Customer represents and warrants that it has obtained all rights and consents required to grant this license.
To access certain features of the Service, Customer must register for an account. Customer agrees to:
If Customer subscribes to a paid plan:
Signals implements security measures including TLS encryption, encryption at rest, private cloud infrastructure, role-based access controls, audit logging, monitoring, and backups.
Customer may request deletion of Customer Personal Data by contacting privacy@returnsignals.com. If End Customers request deletion of their personal data, Customer may submit those requests on their behalf. Deletion requests do not affect data already aggregated or de-identified under Section 9.3, or records retained for legal, security, billing, fraud prevention, compliance, or dispute-resolution purposes.
The Service may connect to or rely on third-party services, including commerce platforms, support tools, messaging providers, consent systems, AI providers, analytics tools, fulfillment systems, warehouse systems, and payment processors. Customer is responsible for maintaining its accounts and permissions with those services and complying with their terms.
THE SERVICE IS PROVIDED “AS IS” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR ERROR-FREE OPERATION.
Signals may provide compliance controls, documentation, and operating guidance, but Signals does not provide legal advice. Customer is responsible for its own legal review and compliance decisions.
IN NO EVENT SHALL SIGNALS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUES, GOODWILL, DATA, OR BUSINESS OPPORTUNITY, WHETHER INCURRED DIRECTLY OR INDIRECTLY.
OUR TOTAL LIABILITY SHALL NOT EXCEED THE GREATER OF $100 OR THE AMOUNTS PAID BY CUSTOMER TO SIGNALS IN THE 12 MONTHS PRECEDING THE CLAIM.
Customer agrees to indemnify and hold Signals harmless from any claims, losses, damages, liabilities, penalties, costs, and expenses arising from Customer’s use of the Service, Customer data, messaging compliance failures, violation of these Terms, or infringement of third-party rights.
We may terminate or suspend access immediately, without prior notice, for:
Customer may terminate its account according to the applicable order form or written agreement. Upon termination, Customer’s right to use the Service will cease.
These Terms are governed by the laws of the State of California, without regard to conflict of law principles. Any disputes shall be resolved in the state or federal courts located in San Francisco County, California.
We may modify these Terms at any time. We will provide notice of material changes at least 30 days before they take effect where required. Continued use of the Service after changes become effective constitutes acceptance.
If any provision of these Terms is held unenforceable, the remaining provisions will remain in full force and effect.
These Terms, our Privacy Policy, and any order form or other written agreement between Customer and Signals constitute the entire agreement between Customer and Signals regarding the Service. Our Messaging Compliance page describes our current public operating policy, but Customer’s legal obligations are not limited to that summary. If an order form or enterprise agreement conflicts with these Terms, the order form or enterprise agreement controls for that Customer.
