SMS Terms & Conditions
The agreement that governs messaging programs operated by Fluid Dynamics LLC DBA TetherCX.
Last updated: August 18, 2026
1. Program name and description
These SMS Terms & Conditions ("Terms") govern text messaging programs operated by Fluid Dynamics LLC DBA TetherCX ("TetherCX," "we," "us," "our") through its product TetherCX (the "Program"). By opting in to any part of the Program, you agree to these Terms. The Program has two parts, described below, and your consent to one part does not extend to the other.
1a. Platform Messaging (reseller/technology services)
TetherCX provides messaging technology to business clients ("Participating Businesses" — e.g., car wash locations and other multi-location service operators). Under Platform Messaging, customers contact a Participating Business by SMS or continue a website webchat by SMS, and that business's staff reply from a shared TetherCX inbox about services, hours, appointments, billing or payment notifications, and related account updates. TetherCX operates the messaging infrastructure on behalf of the Participating Business; the Participating Business is responsible for its own customer relationships, and TetherCX is not a party to the underlying transaction between you and that business. Platform Messaging is transactional/customer-care in nature and is not used by TetherCX to market its own services.
1b. Sales Messaging (TetherCX's own outreach)
TetherCX also operates its own lead-generation and sales communications with prospective business customers who inquire about the TetherCX platform — for example, through the webchat widget on tethercx.com. Under Sales Messaging, TetherCX (not a Participating Business) sends product information, pricing, and sales follow-up directly to the person who submitted the inquiry. This messaging is promotional/marketing in nature.
2. Consent (opt-in)
Platform Messaging consent
Consent is obtained in one of the following ways: (1) you text a Participating Business's number first; (2) you enter and submit your mobile number in that business's website webchat widget to continue the conversation by text; or (3) you provide your mobile number and agree to account SMS communications as part of signing a membership agreement with a Participating Business. Consent under (1) and (2) covers two-way conversational messaging with the business you contacted. Consent under (3) additionally covers recurring account and service notifications related to your membership, such as billing or payment alerts.
Sales Messaging consent
Consent is obtained when you voluntarily submit your name and mobile number through the lead-capture webchat widget on tethercx.com and affirmatively check the consent box displayed above the Submit button. This consent covers marketing and sales follow-up from TetherCX about its own platform. We do not add numbers to Sales Messaging from purchased lists or any other source.
3. Message frequency and rates
Message frequency varies by program and by how often you contact a business or TetherCX responds. Message and data rates may apply. Carriers are not liable for delayed or undelivered messages.
4. Opt-out and help
Reply STOPto opt out of that specific program; you will receive a confirmation and no further messages will be sent under that program unless you opt in again. Opting out of Sales Messaging does not opt you out of Platform Messaging you've separately consented to with a Participating Business, and vice versa. Reply HELP for help, or email hello@tethercx.com.
5. Privacy
How we handle mobile numbers and messaging data for both Platform Messaging and Sales Messaging is described in our Privacy Policy. We do not sell or share your mobile phone number or messaging consent information with third parties for their own marketing purposes. Service providers who help us operate messaging infrastructure (e.g., SMS carriers, hosting, CRM platforms) may process this data solely to deliver the Program on our behalf.
6. Eligibility and acceptable use
You must be the authorized user of the mobile number you provide. Do not use the Program for unlawful, abusive, or fraudulent purposes.
7. Changes
We may update these Terms by posting a revised version on this page with an updated "Last updated" date. Continued use of the Program after changes means you accept the revised Terms.
