Terms of Service

Effective date: 2026-05-07

These Terms of Service ("Terms") govern your use of the CallChair service provided by Lodestar Ventures LLC, a Virginia limited liability company, doing business as CallChair ("CallChair," "we," "us," or "our"). By subscribing to or using CallChair, you ("Customer") agree to these Terms.

1. The Service

CallChair provides an AI-powered voice receptionist service configured specifically for your dental practice. The service includes:

• A dedicated inbound phone number routed to your customized AI assistant ("Riley").
• AI-handled inbound calls including new-patient intake, appointment booking, reschedule requests, after-hours messaging, and general FAQ responses.
• Delivery of call transcripts and booking summaries to your practice via SMS or email.
• Access to call logs and configuration management through our customer portal (when available).

CallChair is a technology service. It is not a licensed healthcare provider and does not provide clinical advice, diagnoses, or medical recommendations. Riley is an AI assistant trained to intake and route calls — clinical decisions remain solely with your licensed providers.

2. Account and eligibility

You must be a legal entity or individual authorized to enter contracts in your jurisdiction. By creating an account, you represent that you have the authority to bind your practice to these Terms.

You are responsible for maintaining the confidentiality of your account credentials and for all activities under your account. Notify us promptly at [email protected] if you suspect unauthorized access.

3. HIPAA and protected health information

If your practice is a HIPAA-covered entity, a signed Business Associate Agreement (BAA) is required before you route patient calls through CallChair. You may request a BAA at [email protected] prior to go-live.

You are responsible for configuring CallChair in accordance with your HIPAA obligations, including ensuring your staff understand that patient information shared on calls may be transcribed and delivered to designated contacts at your practice.

Do not route calls through CallChair before signing the BAA if your practice handles PHI.

4. Fees and payment

Subscription fees are charged monthly in advance based on your selected plan. Current pricing is published at callchair.ai/#pricing and may be updated with 30 days' advance notice to active customers.

Onboarding fee: A one-time onboarding fee applies to new accounts as described at the time of sign-up.

Add-ons (e.g., iPad lease, additional locations) are billed as described at the time you add them.

Payments are processed by Stripe, Inc. By providing your payment information, you authorize us to charge your payment method on a recurring basis per your plan. If a payment fails, we will notify you and may suspend service after 7 days.

All fees are in U.S. dollars and non-refundable except as described in our money-back guarantee. The Starter plan includes a 30-day money-back guarantee on the subscription fee (excluding the onboarding fee) for new customers.

5. Cancellation and termination

By you: You may cancel your subscription at any time by contacting us at [email protected]. Cancellation takes effect at the end of your current billing period. You will retain access to the service through the end of the paid period.

By us: We may suspend or terminate your account immediately if you:

• Violate these Terms or applicable law.
• Route PHI through CallChair without a signed BAA.
• Use CallChair to harass, defraud, or harm callers or third parties.
• Fail to pay overdue invoices after 14 days' written notice.

Upon termination, we will delete your practice configuration data within 30 days and retain call transcripts for the period required by your BAA or applicable law.

6. Acceptable use

You agree not to use CallChair to:

• Impersonate a licensed medical or dental provider in any manner that could harm patients.
• Collect or transmit information from callers without legally required consent or notice.
• Violate any applicable law, including telemarketing, wiretapping, or recording consent laws. You are responsible for obtaining any consents required to record or transcribe calls in your jurisdiction.
• Interfere with or disrupt our infrastructure or attempt to reverse-engineer the service.

Call recording consent: Many states (and some localities) require you to notify callers that their call may be recorded or transcribed. You are solely responsible for ensuring that your use of CallChair complies with all applicable call recording laws in the jurisdictions where you operate. We recommend adding a brief recording-consent disclosure to your incoming call greeting.

7. Intellectual property

CallChair and all technology underlying the service are owned by Lodestar Ventures LLC. Nothing in these Terms grants you a license to our source code, trademarks, or proprietary AI models.

You retain ownership of all data you provide to us, including your practice configuration and any recordings or transcripts delivered to you. You grant us a limited license to process that data solely to provide the service.

8. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT RILEY WILL CORRECTLY HANDLE EVERY CALLER INTERACTION.

CallChair is an AI assistant. It may make mistakes. Do not rely on it as the sole point of contact for clinical emergencies. You should maintain a direct emergency callback process for callers in medical distress.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LODESTAR VENTURES LLC'S TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS SHALL NOT EXCEED THE FEES YOU PAID TO US IN THE 12 MONTHS PRECEDING THE CLAIM.

IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES, INCLUDING LOST REVENUE OR PROFITS, EVEN IF ADVISED OF THE POSSIBILITY.

THESE LIMITATIONS DO NOT APPLY TO EITHER PARTY'S INDEMNIFICATION OBLIGATIONS, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT.

10. Indemnification

You agree to defend, indemnify, and hold harmless Lodestar Ventures LLC from any third-party claims arising from your use of the service in violation of these Terms, your failure to obtain required consents, or your breach of applicable law.

11. Governing law and disputes

These Terms are governed by the laws of the Commonwealth of Virginia, without regard to its conflict-of-law rules. Any dispute arising under these Terms shall first be addressed through good-faith negotiation. If unresolved after 30 days, disputes shall be submitted to binding arbitration in Virginia under the rules of the American Arbitration Association, with the exception that either party may seek injunctive relief in any court of competent jurisdiction.

12. Changes to these Terms

We may update these Terms from time to time. We will post the updated version on this page and email active customers at least 14 days before changes take effect. Continued use of the service after the effective date constitutes acceptance of the updated Terms.
