Terms of Service

The agreement between you and TNS365 for using Not A Lone Worker.

Last updated: 10 July 2026

These terms govern your use of Not A Lone Worker (“the service”), provided by TNS365, a company registered in England & Wales (“we”, “us”, “our”). By creating an account or using the service you agree to these terms. If you’re agreeing on behalf of an organisation, you confirm you’re authorised to bind that organisation.

Important — safety-critical disclaimer.

Not A Lone Worker is a tool to support your lone-worker safety arrangements. It is not a replacement for the emergency services, and not a substitute for your own duty of care as an employer. It does not guarantee that harm will be prevented. Check-ins, AI voice calls and escalation depend on mobile networks, third-party providers and the people you nominate to respond — any of which can fail or be delayed. In an emergency, always call 999. You remain responsible for your workers’ safety, for putting appropriate procedures and trained responders in place, and for acting on any alert the service raises.

1. What the service does

Not A Lone Worker sends scheduled welfare check-ins to workers by SMS, email and app; interprets their responses; makes an AI voice call (“Zoe”) when a worker doesn’t respond; runs a sequential escalation ladder to the contacts you nominate; and keeps an audit trail of everything that happened. The service is provided on an “as available” basis and we may improve, change or add features over time.

2. Your account and responsibilities

  • Keep your login credentials secure; you’re responsible for activity under your account. Account sign-in supports two-factor authentication and we recommend enabling it.
  • Make sure the worker and contact details you enter are accurate and up to date — the service can only reach the numbers and people you give it.
  • Ensure you have a lawful basis and any necessary consent to add your workers and to send them check-ins, and tell them how the service works.
  • Nominate responders who will actually act on escalations, and test your setup before relying on it.

3. Acceptable use

You agree not to:

  • use the service for anything unlawful, or to harass, deceive or endanger anyone;
  • send messages to people who haven’t agreed to receive them, or misuse SMS/voice channels;
  • attempt to break, overload, reverse-engineer or gain unauthorised access to the service;
  • resell or provide the service to third parties except as expressly permitted.

We may suspend an account that puts the service, its other customers or anyone’s safety at risk.

4. Plans, billing and the free trial

  • Subscriptions are billed monthly in advance through our payment processor, Stripe. Prices are shown on our pricing page and exclude VAT unless stated.
  • The Lite plan includes a 14-day free trial, available once per company. Paid billing begins when the trial ends unless you cancel before then.
  • Each plan has usage limits (workers, schedules and welfare checks per month) as set out on the pricing page. The Ultimate plan’s check allowance is offered on a fair-use basis; we’ll contact you before taking any action if usage is materially and persistently beyond the plan.
  • You can cancel anytime from the Stripe customer portal. Cancellation stops future billing and your cover continues to the end of the current paid month. We don’t provide pro-rata refunds for part-months unless required by law.

5. Third-party services

The service relies on third parties including Twilio (SMS and voice), OpenAI (AI voice conversation and message interpretation), Stripe (billing), Mailgun (email) and Cloudflare (security and delivery). Their availability and performance are outside our control, and interruptions to them may affect the service.

6. Availability

We work to keep the service running reliably but don’t guarantee uninterrupted or error-free operation. We may carry out maintenance, and occasional downtime or delays can occur. This is one of the reasons the service must supplement, not replace, your own safety procedures.

7. Liability

Nothing in these terms limits liability for death or personal injury caused by our negligence, for fraud, or for anything that can’t be limited under law. Subject to that, and given the safety-critical disclaimer above, we are not liable for indirect or consequential loss, and our total liability to you in any 12-month period is limited to the fees you paid us for the service in that period. You’re responsible for maintaining your own safety arrangements so that a failure or delay in the service does not leave a worker without help.

8. Data protection

Our handling of personal data is described in our privacy policy, which forms part of these terms. Where we process your workers’ data on your behalf, we do so as your processor under that policy.

9. Changes and termination

We may update these terms as the service develops; we’ll post the new version here with an updated date and, for material changes, aim to let account holders know. You may stop using the service and cancel at any time. We may suspend or end an account for a serious or repeated breach of these terms.

10. Governing law

These terms are governed by the law of England & Wales, and the courts of England & Wales have exclusive jurisdiction over any dispute.
