Terms of service

Effective September 24, 2026

Welcome to Tylum Voice, a product of Calmax Systems ("Calmax", "we," "us," or "our"). Tylum Voice answers phone calls for small businesses with an intelligent receptionist (an AI system) named Sam. By creating an account or using the service, you agree to these Terms of Service and our Privacy Policy. If you do not agree, do not use the service.

1. What Tylum Voice does

When you connect a phone number to Tylum Voice, Sam answers calls on your behalf. Depending on your plan and how you've configured Sam, Sam can:

  • Answer questions about your business using facts you approve, including facts we import from your website when you set up your account
  • Take a message and email you the details
  • Check your calendar's free/busy times and book an appointment while the caller is still on the line (Pro plan)
  • Transfer a call to a person on your staff, either because the caller asked or because the call matches rules you set (urgent or VIP callers, on the Pro plan)

Sam is an automated system. It is not a human, and it does not connect you to one unless a call is transferred. Sam does not send text messages to you or to your callers on your business's behalf — notifications go to you by email, and a caller who books an appointment gets a confirmation by email if they give us one, not by text.

2. Account registration

To use Tylum Voice, you must provide accurate registration information, be at least 18 years of age, and keep your account credentials secure. You are responsible for activity under your account. Each business has a single owner login; Tylum Voice does not currently support inviting other people to sign in to your account.

3. Calls, recordings and transcripts

By using Tylum Voice, you authorize us to:

  • Answer incoming calls to your Tylum number using our intelligent receptionist
  • Record the call and produce a written transcript, so you have a record of what was said
  • Store the recording and transcript on Calmax infrastructure located in California
  • Use the transcript to take messages, answer questions, and book appointments as described above

Recording stops the moment a call is transferred to a member of your staff — Sam does not record or transcribe the conversation once a person on your team picks up. You can turn call recording off entirely for your business in Settings; transcripts are still produced so Sam can do its job, but no audio is kept.

Callers to a Tylum-answered line may be told the call may be recorded, consistent with applicable law. You are responsible for confirming Tylum Voice's call recording features comply with the law in the places you and your callers are located.

4. Your calendar

If you connect a calendar, Tylum Voice reads it through a read-only link you provide, to check when you're free. We never write to your calendar directly. When Sam books an appointment, we send a calendar invite by email to the address you set for bookings, and you (or whoever manages that inbox) accepts it into your calendar the normal way.

5. Acceptable use

You agree not to:

  • Use the service for any illegal purpose
  • Attempt to gain unauthorized access to our systems or another business's account
  • Interfere with or disrupt the service
  • Reverse engineer or decompile our software
  • Use Sam to place calls that violate telemarketing, robocall, or consent laws
  • Share your account credentials with people outside your business

6. Subscription and payment

Free trial

New accounts get a 14-day free trial. A card is required up front to start a trial; you are not charged until the trial ends unless you cancel first.

Paid plans

  • Basic is $49/month and includes 300 minutes of calls
  • Pro is $129/month and includes 1,000 minutes of calls, plus warm transfers, urgent/VIP call rules, and calendar booking
  • Minutes beyond your plan's allowance are billed at $0.20/minute
  • Payments are processed by Stripe. We do not store your full card number on our servers
  • Prices are subject to change with 30 days' notice to existing subscribers

Cancellation and deleting your account

You can cancel your subscription at any time from Settings; we cancel it with Stripe so you are never billed again after that. Deleting your account is a separate, permanent step, also in Settings: it immediately and permanently deletes your business record and everything tied to it — call history, recordings, transcripts, messages, bookings, and your settings — after your subscription is cancelled with Stripe. There is no grace period or recovery once you confirm an account deletion.

7. Intellectual property

Tylum Voice and its content, features, and functionality are owned by Calmax Systems. Your business information, call data, and anything Sam records or transcribes on your behalf remain yours. We do not use your call data to train models for other customers.

8. Service availability

We aim for high availability but do not guarantee uninterrupted service. We may perform scheduled maintenance, suspend service for security reasons, or modify or discontinue features with reasonable notice. If Tylum Voice cannot answer a call, our released numbers and connection settings are designed so the call fails clearly rather than silently.

9. Limitation of liability

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

  • We do not guarantee Sam will handle every call correctly or that every classification, booking, or transfer decision will be accurate
  • We are not liable for indirect, incidental, special, or consequential damages
  • Our total liability is limited to the amount you paid us in the 12 months preceding the claim

10. Indemnification

You agree to indemnify and hold harmless Calmax Systems, its officers, and employees from claims, damages, or expenses arising from your use of the service or violation of these terms.

11. Termination

We may suspend or terminate your account if you violate these terms. Provisions that should survive termination (Limitation of Liability, Indemnification, Governing Law) remain in effect after termination.

12. Changes to these terms

We may update these terms periodically. We will notify you of material changes by email at least 14 days before they take effect. Continued use after the effective date constitutes acceptance.

13. Governing law

These terms are governed by the laws of the State of California, USA, without regard to conflict of law principles. Before filing any formal dispute, contact us at [email protected] so we can try to resolve it informally first.
