Terms of Service

Last updated: 6 July 2026. Please read these terms carefully before using CallNudge. By signing up or using the service, you agree to be bound by them.

1. About CallNudge

CallNudge is a trading name and missed-call answering service operated by OmniAssist AI Ltd, company number 16388166, registered in England and Wales. Our registered office is 124-128 City Rd, London, England, EC1V 2NX. The service answers calls diverted from your existing phone number, collects the caller's details, and delivers a summary to you by email. If a call is marked urgent and you have agreed to receive operational texts, we also send an SMS alert to your chosen mobile number.

In these terms, "we", "us", and "our" refer to OmniAssist AI Ltd. "You" and "your" refer to the business customer who has signed up for the service. "Callers" means third parties who telephone your business number and are diverted to CallNudge.

2. Eligibility

CallNudge is intended for use by businesses operating in the United Kingdom. By signing up, you confirm that:

  • You are at least 18 years old
  • You are signing up on behalf of a legitimate business
  • You have the authority to enter into this agreement on behalf of that business
  • The phone number you divert to us is a number you are authorised to use

3. The free trial

New customers may be eligible for a 30-day free trial. During the free trial:

  • The service is provided free of charge for up to 30 days, or up to 20 captured calls, whichever comes first, starting from the date your account is activated - that is, the date your CallNudge service goes live, once call forwarding is set up and a successful test call confirms the calls you would have missed are being captured
  • No payment card is required to start the free trial
  • All standard service features are available during the free trial
  • The free trial is available to new customers only - one trial per business
  • We reserve the right to withdraw or modify free-trial availability at any time for new sign-ups

At the end of the free trial, you will be notified by email. Your service will not automatically continue to a paid subscription without you actively choosing to do so. If you do not subscribe, your account will be deactivated. Call data and account records are then handled under the separate retention periods in our Privacy Policy.

4. Subscription and payment

If you choose to continue after the free trial, our subscription plans are Early Access at £60 per month (50 calls included), Trade at £100 per month (100 calls included), and Busy Trade at £150 per month(200 calls included), each covering one phone line. Calls beyond your plan’s monthly allowance are charged at £1 per call. OmniAssist AI Ltd is not currently VAT-registered, so no VAT is currently charged. This is billed monthly in advance.

  • Annual billing is available at a discounted rate - contact us for details
  • If VAT becomes legally applicable, it may be added to the subscription price after at least 30 days written notice
  • We reserve the right to change our pricing with at least 30 days written notice to active subscribers
  • Payments are processed securely by our payment provider. We do not store your full card details
  • If a payment fails, we will notify you and attempt to collect payment again. Continued non-payment may result in suspension of the service

5. Cancellation

You may cancel your subscription at any time. There are no minimum contract periods and no cancellation fees.

  • To cancel, use our contact form and select Existing customer or cancellation. Keep the on-screen submission acknowledgement for your records
  • Cancellation takes effect at the end of your current billing period - you will continue to have access to the service until that date
  • We do not offer refunds for partial months unless we have failed to provide the service
  • On cancellation, call data and account records follow the retention periods in our Privacy Policy, unless we are legally required to keep particular records for longer

We may also cancel or suspend your account if you breach these terms, use the service for unlawful purposes, or repeatedly fail to make payment.

6. What we provide

We will use reasonable skill and care to provide the CallNudge service, including:

  • Answering calls diverted to your CallNudge number during the hours agreed at setup
  • Collecting the caller's name, phone number, and reason for calling
  • Delivering a written call summary to you by email
  • Sending an operational SMS alert to your chosen mobile when a call is marked urgent, if you have agreed to receive these alerts
  • UK-based onboarding support and customer service during UK business hours

7. What we do not guarantee

The CallNudge service relies on telephone networks, third-party infrastructure, and AI transcription technology. While we work hard to provide a reliable service, we cannot guarantee:

  • 100% uptime or uninterrupted availability
  • That every call diverted to us will be answered successfully
  • That transcripts or summaries will be perfectly accurate in every case - they are AI-generated and may contain errors
  • That callers will always provide accurate information

Call summaries are provided to help you follow up with callers. You remain responsible for verifying details with callers before acting on them.

8. Your responsibilities

As a CallNudge customer, you agree to:

  • Set up call diversion correctly on your phone or landline, following our guidance
  • Ensure your callers are aware that unanswered calls may be handled by an automated call assistant - for example, through your voicemail greeting or business website
  • Comply with all applicable laws when using the service, including data protection law
  • Not use the service for any unlawful, abusive, or fraudulent purpose
  • Not attempt to reverse-engineer, copy, or resell any part of the service
  • Keep your account credentials secure and notify us immediately if you suspect unauthorised access
  • Keep delivered call-summary emails and SMS copies only for as long as you need them, and delete the copies you control when a valid caller-rights request requires it

You are the data controller for your callers' personal data and for the email and SMS copies delivered into your own accounts. We act as your data processor when handling caller data to provide CallNudge. You are responsible for ensuring you have a lawful basis to collect and use that data, for handling data-subject requests from your callers, and for telling us promptly when a request requires action in systems we operate.

9. Excluded use cases

CallNudge is designed to handle general missed-call enquiries for standard UK small businesses. The service must not be used as a channel for any of the following without additional safeguards agreed in writing with us before the service goes live:

  • Medical advice - including triage, diagnosis, prescription queries, or any interaction where a caller may rely on the response to make a health decision
  • Legal advice - including any interaction where a caller may rely on the response as legal guidance
  • Financial advice - including regulated financial products, investments, credit, or insurance recommendations
  • Emergency services - the service must never be positioned or used as a substitute for 999, 111, or any other emergency or urgent-response line
  • Children's services - any service whose primary callers are or may be minors
  • Care services involving vulnerable adults or children - including social care, mental health crisis lines, domestic abuse services, or any setting where callers may be in a vulnerable state

If you are unsure whether your use case falls within these exclusions, use our contact form and select Service suitability before setting up the service. We reserve the right to suspend or terminate accounts that use the service in an excluded category without prior written agreement.

10. Limitation of liability

To the extent permitted by law, our total liability to you for any claim arising from or related to the service is limited to the total fees you have paid to us in the three months immediately before the claim arose.

We are not liable for:

  • Loss of profit, revenue, business, or contracts
  • Loss of anticipated savings
  • Loss of data or information
  • Any indirect or consequential loss
  • Losses caused by events outside our reasonable control (including network outages, power failures, or acts of government)

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded under English law.

11. Intellectual property

All intellectual property rights in the CallNudge platform, software, and branding belong to OmniAssist AI Ltd. You are granted a limited, non-exclusive, non-transferable licence to use the service during your subscription.

Call summaries and transcripts generated by the service are provided to you for your business use. You own the underlying content (the caller's words), but the format and delivery of summaries remains our intellectual property.

12. Changes to the service and these terms

We may update or change the service and these terms from time to time. For material changes, we will give you at least 30 days notice by email. Continued use of the service after the notice period means you accept the updated terms.

If you do not accept a change, you may cancel your subscription before it takes effect and receive a pro-rata refund for any unused portion of a paid month.

13. Governing law

These terms are governed by the laws of England and Wales. Any disputes arising from or related to these terms or the service shall be subject to the exclusive jurisdiction of the courts of England and Wales.
