Terms of Service

Last updated: October 6, 2026

These terms are the agreement between you and CallBooker when you use callbooker.com and the CallBooker service. By creating an account or using the service, you accept them. If you use CallBooker for a company, you accept them on its behalf.

1. The service

CallBooker lets you create AI voice agents that call your leads by phone, talk with them, and book meetings on your calendar or record the outcome. The voice AI is provided by ElevenLabs, calls are placed through your own Twilio account, and meetings are booked in your Google Calendar or Calendly.

AI can make mistakes. You are responsible for reviewing what your agents say (your brief, prompt and knowledge) and the results of their calls.

2. Your account

  • You must be at least 18 and give accurate information.
  • Keep your password and API keys secret. You are responsible for everything done with your account and keys.
  • Tell us right away at support@callbooker.com if you think your account or a key was misused.

3. Calling rules (your responsibility)

You decide who your agents call, when and why. Before your account can place calls you accept our calling agreement, and you must follow it at all times:

  • Consent. Only call people who agreed to be contacted, for example by filling in a form or opting in. In the US, calls made with an AI or artificial voice are covered by the Telephone Consumer Protection Act (TCPA) and generally need the person's prior express consent, and prior express written consent for marketing calls.
  • Do-not-call. Respect national and state do-not-call registries and every request not to be called. When a lead asks not to be called again, CallBooker marks them "do not call" and won't call them again.
  • Calling hours. Call only at times allowed where the lead is (in the US, generally 8 a.m. to 9 p.m. local time).
  • AI disclosure and recording. Calls are made by an AI voice and are recorded and transcribed. Your agents say they are an AI whenever asked. Follow the call-recording and disclosure laws where your leads are; each agent has a setting to say at the start that the call is recorded.
  • Local laws. Follow the laws of every place you call, such as the Telemarketing Sales Rule and state laws in the US, the GDPR and ePrivacy rules in the EU, PECR in the UK, and CASL and CRTC rules in Canada.

4. Acceptable use

You may not use CallBooker to:

  • call people without the consent the law requires, or call numbers you bought or scraped without it;
  • harass, threaten, deceive or defraud anyone, or pretend to be a real person or another company;
  • spoof caller ID or hide who is calling;
  • call emergency numbers, hospitals' emergency lines or other protected numbers;
  • collect debts in breach of debt-collection laws, or make political robocalls;
  • sell or promote anything illegal;
  • break, overload, reverse engineer or get around the limits of the service.

You must also follow the terms and acceptable use policies of Twilio and ElevenLabs, because your calls go through them.

5. Twilio, calendars and other services

  • Calls go through your own Twilio account. Twilio bills you directly for phone numbers and calls, and you are responsible for your Twilio account and its settings.
  • When you connect Google Calendar or Calendly, you let CallBooker read your availability and create events for meetings your agents book.
  • We are not responsible for outages or changes in services we don't control, such as Twilio, ElevenLabs, Google or Calendly.

6. Plans, minutes and payment

  • The Free plan includes 10 AI talk minutes, once. Paid plans include a number of AI talk minutes per billing period; unused minutes don't roll over.
  • When your minutes run out, new calls stop until you upgrade or your next period starts. We never charge you extra for going over.
  • Paid plans renew automatically each month or year until you cancel in Settings → Billing. Payments are handled by Stripe. Plan changes are prorated.
  • Fees are not refundable except where the law requires it or we decide otherwise. Prices exclude taxes.
  • We may change prices with at least 30 days' notice; the change applies from your next renewal.

7. Your content and data

Your leads, scripts, knowledge and call results belong to you. You give us permission to use them only to run the service for you. You confirm you have the right to give us your leads' data and to have them called. How we handle personal data is described in our Privacy Policy, and our Data Processing Agreement (part of these Terms) covers the leads’ data we process for you.

8. Suspension and ending

  • You can stop using CallBooker and cancel at any time.
  • We may suspend calling or close an account that breaks these terms, the calling rules or the law, gets serious complaints, or puts the service or others at risk. Where possible, we'll tell you first.

9. Warranties and liability

CallBooker is provided "as is". We don't promise that it will always be available, error-free, or that it will produce any number of meetings or sales.

To the extent the law allows, we are not liable for indirect or consequential losses (such as lost profits or lost data), and our total liability is limited to the amount you paid us in the 12 months before the claim.

You will defend and compensate CallBooker for claims, fines and costs caused by your calls, your content, or your breach of these terms or the law, including calling laws.

10. Changes to these terms

We may update these terms. For important changes we'll tell you by email or in the app, and you may be asked to accept them again before placing calls.

11. Governing law

These terms are governed by the laws of the State of California, United States, and disputes go to the courts located in California, unless the law where you live says otherwise.
