Early-access draft. These Terms are a v1 working version that has not yet been reviewed by counsel. We will update this page when our attorney completes review. By using the Service you accept these Terms as written; if the post-review version is materially different we will give you 30 days’ email notice before it takes effect.

These Terms of Service (“Terms”) govern your use of the website at https://tenfourpro.com (the “Site”) and the AI assistant service (“Service”) provided by TenFour Pro LLC, a California limited liability company (“TenFour Pro,” “we,” “us,” or “our”). By creating an account, forwarding calls to the Service, or otherwise using the Service, you (“Customer,” “you”) agree to these Terms.

1. The Service is NOT 911 and NOT a substitute for emergency services

READ THIS FIRST. The Service is an AI-mediated answering tool. It is NOT an emergency-response service, NOT a regulated alarm-monitoring service, and NOT a substitute for dialing 911. The Service may detect certain keywords associated with life-threatening emergencies and instruct callers to dial 911 themselves. We do not contact emergency services on your or your caller’s behalf and we do not guarantee detection of any particular emergency. You and your callers remain solely responsible for contacting emergency services when needed.

2. The Service

The Service answers inbound voice calls forwarded by you, collects intake information, classifies urgency using per-trade rules, books non-emergency appointments to a calendar you authorize, and sends SMS notifications to your designated owner phone number to request approval before any urgent dispatch confirmation. The Service is delivered through subprocessors listed in Section 11.

3. Subscription, fees, renewal, cancellation

The founding-customer plan is $199 per month, billed monthly. Your subscription renews automatically each month at the then-current rate until you cancel. You can cancel anytime from your account dashboard or by emailing support@tenfourpro.com. Cancellation takes effect at the end of your current billing period; you keep access through that period. We follow the requirements of California Business and Professions Code Section 17602 for auto-renewing subscriptions: you can review your renewal terms anytime in your account, and we will email you a renewal reminder for any price change. Late payment may result in suspension after 10 days’ notice.

Founding-customer price lock. The $199 founding-customer price is locked for 12 months from your activation date. After 12 months you keep the founding-customer designation but the price may be adjusted to then-current standard pricing with 30 days’ email notice.

4. Acceptable use

You will not use the Service to: (a) make or facilitate unlawful calls or messages; (b) violate the Telephone Consumer Protection Act (TCPA) or any state telemarketing law; (c) impersonate or clone the voice of any person without consent; (d) call numbers on any internal or governmental do-not-call list; (e) abuse, harass, or threaten any caller or third party; (f) reverse-engineer, scrape, or interfere with the Service; or (g) use the demo phone line for any purpose other than evaluating the Service.

5. Your responsibilities

You warrant that:

You own or have legal authority over each phone number you forward to the Service.
You hold any licenses required for the trade work you perform, including any contractor licensing required by the California Contractors State License Board (Bus. & Prof. Code § 7000 et seq.).
You have obtained any consents required from your own callers, customers, and contacts before the Service interacts with them, including TCPA consent for any SMS the Service sends on your behalf.
You are the “Sender” for purposes of TCPA, A2P 10DLC, and CTIA messaging principles. You authorize TenFour Pro to submit A2P 10DLC registration to The Campaign Registry on your behalf and warrant that the information you provide (legal name, EIN, sample messages, opt-in flow) is true and accurate.
You will not forward calls from regulated lines you do not control, including 911 Public Safety Answering Points, medical hotlines, or any line subject to specific regulatory disclosure rules.
You will not invoice or collect payment through the Service. Payment for any work booked through the Service is solely between you and your caller; TenFour Pro is not a payment processor or money transmitter.

California is a two-party-consent jurisdiction for recording confidential communications (California Penal Code §§ 631, 632, 632.7). The Service announces at the start of every call that the call is being recorded and answered by an AI virtual assistant. Continuing the call after this disclosure constitutes consent under California case law (Kearney v. Salomon Smith Barney, 39 Cal. 4th 95 (2006); Flanagan v. Flanagan, 27 Cal. 4th 766 (2002)). Our AI disclosure also complies with California Business and Professions Code Section 17940 (the B.O.T. Act). If a caller refuses consent, the Service ends the call cleanly without storing a recording.

You authorize TenFour Pro to record calls forwarded by you and to process those recordings on your behalf as a service provider under the California Consumer Privacy Act, as amended by the California Privacy Rights Act (collectively, “CCPA/CPRA”).

7. Data ownership, IP, service-provider status

You own the content of calls forwarded by you, including recordings, transcripts, and summaries of those calls (“Customer Data”). You grant TenFour Pro a non-exclusive license to process Customer Data solely to deliver and improve the Service.

TenFour Pro owns the Service platform, models, prompts, software, and any aggregated or fully de-identified analytics derived from operation of the Service. We may use de-identified analytics to improve our models and Service quality; we treat de-identification under the CCPA/CPRA safe harbor (Cal. Civ. Code § 1798.140(m)) requiring technical, contractual, and business-process safeguards against re-identification.

TenFour Pro is your “service provider” under California Civil Code Section 1798.140(ag) for personal information about your callers. We will: (a) use that personal information only to provide the Service to you; (b) not sell or share it; (c) not combine it with personal information from other sources except as permitted; (d) not use it for our own commercial purposes outside the Service; (e) cooperate with reasonable audits; (f) return or delete it on your written request; and (g) notify you of new subprocessors with 30 days’ advance email notice.

8. Warranty disclaimer

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE MAXIMUM EXTENT PERMITTED BY LAW, TENFOUR PRO DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted, error-free, or accurate in classifying urgency or transcribing calls. The Service is in early access; features, availability, and pricing may change.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TENFOUR PRO’S TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE IS LIMITED TO THE FEES YOU PAID FOR THE SERVICE IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. TENFOUR PRO IS NOT LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS OR LOST DATA, EVEN IF ADVISED OF THE POSSIBILITY. These limits do not apply to liability for fraud, gross negligence, willful misconduct, or any liability that cannot be limited by law under California Civil Code Section 1668.

10. Indemnification

You indemnify TenFour Pro against any third-party claim arising from: (a) your callers’ or customers’ TCPA, A2P 10DLC, or CIPA claims where consent was your responsibility under Section 5; (b) any unlicensed contractor work booked through the Service; (c) the content of calls you forward; (d) your breach of these Terms.

We indemnify you against any third-party claim that the Service platform, as provided by us and used in accordance with these Terms, infringes that party’s US intellectual property rights.

11. Subprocessors

The Service is delivered through the following subprocessors (current as of the date above):

Vapi (voice orchestration)
Twilio (SMS delivery and inbound voice routing)
Google (Calendar API, for non-emergency bookings)
Anthropic (AI urgency classification, primary)
OpenAI (AI urgency classification, fallback)
Cloudflare (Turnstile anti-spam and CDN)
Railway (hosting; underlying Postgres and Redis)
Resend (transactional email; lead notifications and confirmations)

We may add or change subprocessors with 30 days’ advance email notice. You may object to a new subprocessor by writing to support@tenfourpro.com; if we cannot reasonably accommodate the objection you may terminate the Service for the remainder of any prepaid period and receive a prorated refund.

12. Termination and data export

Either party may terminate for material breach with 15 days’ notice and an opportunity to cure. We may suspend the Service for non-payment, abuse, or imminent risk to the Service or other customers. On termination we will, for 30 days, make Customer Data available for export in a reasonable machine-readable format. After 30 days we will delete Customer Data on our standard retention schedule (see the Privacy Policy).

13. Governing law and venue

These Terms are governed by the laws of the State of California without regard to its conflict-of-laws rules. The exclusive venue for any dispute is the state or federal courts located in the City and County of San Francisco, California, and both parties consent to personal jurisdiction there. Each party waives any right to a jury trial.

14. Changes to these Terms

We may update these Terms from time to time. Material changes will be emailed to your account email with at least 30 days’ notice. Continued use of the Service after the effective date of a change constitutes acceptance.

15. Survival

Sections 1, 6, 7, 8, 9, 10, 13, and any other terms that by their nature should survive will survive termination of these Terms.

16. Miscellaneous

These Terms are the entire agreement between you and TenFour Pro on this subject. Neither party may assign without the other’s written consent, except that TenFour Pro may assign in connection with a merger, acquisition, or sale of substantially all assets. Notices to you go to your account email. Notices to us go to legal@tenfourpro.com. If any provision is unenforceable, the remainder stays in force. Failure to enforce a provision is not a waiver.
