Terms & Conditions

Last updated: August 2026

For US customers and Users only; UK and rest-of-world customers are covered by our separate Terms and Conditions.

1. Who We Are

The Sentry Devices Ltd (“Sentry,” “Company,” “we,” “us,” “our”) is a company registered in England and Wales, company number 12792846, registered office at 173 King Street, Ramsgate, Kent, CT11 8PN, United Kingdom. We do not currently have a US subsidiary; Sentry itself is the contracting party for US customers.

2. About These Terms

These Terms of Service (“Terms”) govern access to and use of the Sentry lone worker safety application and associated services (the “Service”) by customers and Users located in the United States. They apply whether you use the Service as an individual who has subscribed directly through an app store, or as a worker of an organization that has subscribed to the Service (a “Business Customer”).

If a Business Customer has signed a separate written agreement or order form with us that conflicts with these Terms, that separate agreement takes priority for that Business Customer.

BY DOWNLOADING, REGISTERING FOR, OR USING THE SERVICE, YOU AGREE TO BE BOUND BY THESE TERMS, INCLUDING THE ARBITRATION AGREEMENT AND CLASS ACTION WAIVER IN CLAUSE 20, AND BY OUR PRIVACY POLICY.

3. Definitions

Business Customer: an organization that has subscribed to the Service for use by its workers.

User / “you”: anyone using the Service, whether as an individual subscriber or as a worker authorized by a Business Customer.

Administrator: a person authorized by a Business Customer to manage its account, add or remove Users, and view monitoring data.

Content: alerts, check-in data, location data, messages, and any audio or video captured through the Service.

Subscription: the paid plan giving access to the Service.

Personal Information: has the meaning given in applicable US state privacy law, and generally includes information that identifies, relates to, or could reasonably be linked with a particular individual or household.

4. Eligibility

The Service is designed for use across lone-working industries, including property, events, home care, and field-based roles. Different Users reach it in different ways, each with a different age position, and the position for US Users is stricter in one respect than elsewhere because of the federal Children's Online Privacy Protection Act (“COPPA”):

  • Individual App Store subscribers: you must be 18 or over to subscribe directly and enter into a contract with us.
  • Workers added by a Business Customer: the Business Customer may add a worker as a User from age 16, where that reflects a genuine working relationship lawful under federal and applicable state law. Minimum working age and permitted duties for minors vary by state, and the Business Customer is solely responsible for confirming the worker's age, eligibility, and compliance with the child labor laws of the state in which the worker is employed.
  • Friends and family added by a User: a User may allocate their free additional licenses to friends or family who are 13 years of age or older. Unlike our UK Terms, we do not permit US Users to allocate a license to anyone under 13, because we do not currently operate the verifiable parental consent process COPPA requires before collecting personal information from a child under 13. By allocating a license, a User represents and warrants that the recipient is at least 13 years old, and remains fully responsible for that person's use of the Service and for any parental consent that may be required by law for a 13-to-17-year-old.

We rely on the representations in this clause 4 and do not independently verify age. We do not knowingly collect personal information from anyone under 13. If we learn that we have done so, we will delete it as described in clause 16.

5. What the Service Does (and Does Not Do)

This section matters more than any other in these Terms, given what the Service is for. Please read it alongside clause 13 (Disclaimer of Warranties) and clause 14 (Limitation of Liability).

5.1 The Service is a lone worker monitoring and alerting tool. It lets Users check in, share their location, and raise alerts (including panic/SOS alerts), which are made visible to nominated contacts, Administrators, or monitoring personnel as configured by the Business Customer.

5.2 THE SERVICE IS NOT AN EMERGENCY SERVICE. It is not a substitute for, and does not replace, contacting 911 or other local emergency services directly. In an emergency, you should always contact emergency services yourself, or ask someone else to do so, in addition to using any alert function in the Service.

5.3 We do not guarantee that:

  • any alert will be received, reviewed, or acted upon within any particular time, or at all;
  • the Service will be continuous, uninterrupted, or error-free;
  • location data will be accurate, as it depends on device GPS, network signal, and other factors outside our control;
  • audio or video capture will work in all conditions (for example, poor connectivity, low light, or where device permissions are not granted).

5.4 When a User activates a panic alarm, the recipients they have nominated within the app (which may include managers, Administrators, or colleagues, all within the same Business Customer, or a friend or family member where the User has chosen one) are notified and can see the User's live location on the in-app map. A recipient can choose to respond, which shows both the recipient and the responding party a direction to follow to reach the User. More than one recipient can respond at the same time. As far as we are aware, no third-party monitoring provider is involved in this process; responses come only from people the User or their organization has nominated.

5.5 The Service depends on the User's device having power, signal or data connectivity, correct app permissions (location, camera, microphone, notifications), and being kept up to date. We are not responsible for failures caused by device or network issues outside our control.

5.6 Business Customers remain responsible for their own lone-working policies, risk assessments, and emergency and safety procedures under applicable federal and state occupational safety law (including, where applicable, OSHA regulations and state equivalents). The Service is a tool to support those procedures, not a replacement for them.

5.7 Audio and video recording; state consent laws. Activating a panic alarm may automatically record audio and video. By activating this feature, you consent to being recorded. Many states, including but not limited to California, Illinois, Florida, Pennsylvania, and Washington, require the consent of all parties to a recorded conversation, not just the person activating the recording. YOU ACKNOWLEDGE AND AGREE THAT YOU, AND NOT SENTRY, ARE SOLELY RESPONSIBLE FOR DETERMINING WHETHER YOUR USE OF THIS FEATURE IN A GIVEN LOCATION AND STATE COMPLIES WITH APPLICABLE RECORDING CONSENT LAWS, INCLUDING WHERE THE RECORDING MAY CAPTURE ANOTHER PERSON'S CONVERSATION WITHOUT THEIR KNOWLEDGE. Business Customers must inform their workers about this recording feature and its legal implications before deployment, and are responsible for their own and their workers' compliance with the recording consent laws of every state in which they operate.

5.8 Biometric authentication to stop an alarm. To stop an active alarm, and the audio/video recording that goes with it, the User must authenticate using their device's own built-in biometric unlock feature (such as Face ID, Touch ID, or an equivalent Android biometric method). This authentication happens entirely on the User's device, through the device operating system, not through the Service. We do not receive, collect, store, or have access to any facial image, fingerprint, or other biometric identifier; we only receive confirmation that the device's own authentication succeeded. One consequence of this design is that only the User can stop the recording, so if a User is unable to authenticate, an alarm may continue recording for longer, which is relevant to clause 5.7.

6. Business Customer Accounts

6.1 A Business Customer may authorize Administrators to manage Users and configure alert routing, and may view Content generated by Users in the course of their work, other than panic alarm video. Panic alarm video is only ever accessible to the User who recorded it, as described in our Privacy Policy; Administrators cannot view it through the portal, and a User may choose to share it further themselves if they wish.

6.2 The Business Customer is responsible for:

  • having a lawful basis for adding its workers as Users, and giving workers any notice about monitoring required by applicable state privacy law and employment law;
  • making sure Users understand the use of location, audio, and video capture features as part of their role, and providing any notice or consent required by applicable state recording consent law;
  • the accuracy of information it gives us about its Users.

6.3 We are the Business (or Controller) with respect to the account and billing data described in our Privacy Policy (for example, admin contact details and license records). For the operational data your Users generate through the Service, check-ins, location sharing, alerts, incident reports, and any video captured through the panic alarm feature, we act only as your Service Provider (or Processor): we store this data on your instructions and do not access it. You are the Business or Controller of that data and are responsible for your own compliance with applicable state privacy law in respect of it, including providing any required notice to your workers and handling their data subject requests.

6.4 Data Processing Terms. Clauses 6.4 to 6.7 form the written contract required by applicable state privacy law (including the California Consumer Privacy Act, as amended) between you, as Business or Controller, and us, as Service Provider or Processor, for the operational data described in clause 6.3. By accepting these Terms when creating a portal account, you agree to these terms in that capacity, and we agree to them as Service Provider or Processor. You do not need a separate signed agreement with us for this to take effect.

  • Purpose: we will process this data only to provide the Service and for no other commercial purpose, and only as necessary to perform the services described in these Terms.
  • No sale or sharing: we will not sell or share this data, and will not retain, use, or disclose it for any purpose other than performing the services under these Terms, including not for our own commercial purposes outside the direct business relationship with you.
  • No combining: we will not combine data we process on your behalf with data received from another Business Customer or collected from our own interactions with an individual, except as permitted by applicable law.
  • Confidentiality and security: we will keep this data confidential and apply appropriate technical and organizational security measures.
  • Sub-processors: we will only engage a sub-processor (such as our hosting provider) under a written contract imposing equivalent obligations, and will tell you of any material change in sub-processor.
  • Assistance: we will assist you, so far as reasonably possible, in responding to consumer or data subject requests and in meeting your own obligations under applicable state privacy law.
  • Breach notice: we will notify you without undue delay if we become aware of a security incident affecting this data.
  • Deletion or return: we will delete or return this data to you at the end of your Subscription, except where we are required to keep it by law.
  • Audit and certification: we will make available information reasonably necessary to demonstrate our compliance with this clause 6.4, and we certify that we understand and will comply with these restrictions.

6.5 We may need to engage other sub-processors from time to time to provide the Service; we will keep you informed of any material changes through the usual notice channels in clause 17.

6.6 We do not sell or share Personal Information, as those terms are defined under applicable state privacy law, whether the data is described in clause 6.3 or otherwise.

6.7 Friends and Family Licenses. Each adult individual User receives 3 free additional licenses to give to friends or family aged 13 or over (see clause 4). We have no visibility of who these licenses are given to or how they are used, beyond knowing a license has been allocated. The User allocating the license is solely responsible for that person's use of the Service, including their eligibility under clause 4 and their conduct.

7. Subscriptions and Payment

7.1 Business Subscriptions

Business Customers pay recurring fees as set out in their order, or in the pricing published on our website, billed in advance monthly or annually as selected. Subscriptions do not renew automatically. We will send reminder emails ahead of the renewal date, and it is the Business Customer's responsibility to arrange payment or confirm cancellation before that date.

7.2 Individual Subscriptions via App Store

If you subscribe directly through the Apple App Store or Google Play Store, your purchase, billing, and cancellation are governed by that store's own terms, and payment is collected by the store, not by us directly.

7.3 Price Changes

We may change Subscription fees. For Business Customers, we will give at least 30 days' notice before a change takes effect on renewal. For individual App Store subscribers, price changes are notified and managed through the App Store.

7.4 Cancellation and Refunds

Business Customers may cancel in line with the notice period in their order form, or otherwise on [30] days' written notice. Fees already paid for the current billing period are not refundable, except where required by law. Because Subscriptions do not renew automatically, no separate cancellation right is needed to avoid an unwanted renewal charge.

8. Acceptable Use

You must not:

  • use the Service to harass, stalk, or unlawfully monitor any individual;
  • attempt to circumvent the Service's security;
  • misuse alert functions, including raising false alerts;
  • use the Service for any purpose other than genuine lone-worker safety monitoring in a work context;
  • reverse-engineer, resell, or white-label the Service without our written consent;
  • use the Service to record another person's audio or video in violation of applicable state recording consent law.

9. Intellectual Property

The Service, and all software, trademarks, and content in it (excluding Content generated by Users), belong to us or our licensors. We grant you a limited, non-exclusive, non-transferable license to use the Service for its intended purpose for as long as your Subscription lasts.

10. Data Protection and Privacy

We process personal information in accordance with our Privacy Policy, available at thesentry.co.uk/privacy-policy-us, which forms part of these Terms.

11. Third-Party Services

The Service relies on third-party infrastructure, including mapping, push notification, payment, and app store services. We are not responsible for the availability or performance of third-party services outside our reasonable control.

12. Indemnification

You agree to indemnify, defend, and hold harmless Sentry, its officers, directors, and employees, from any claim, demand, loss, or damage, including reasonable attorneys' fees, arising out of: your breach of these Terms, including any breach of the age representations in clause 4; your misuse of the Service; your violation of any law, including state audio and video recording consent laws and COPPA; or, if you are a Business Customer, a claim brought by one of your workers or their family members arising from your own acts or omissions, including your safety and lone-working procedures, and your decisions about whether and how to use the Service's audio and video recording features.

13. DISCLAIMER OF WARRANTIES

THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING THE IMPLIED 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 ANY ALERT WILL BE RECEIVED OR ACTED UPON. SOME STATES DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.

14. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (A) SENTRY WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; AND (B) OUR TOTAL LIABILITY TO A BUSINESS CUSTOMER ARISING OUT OF OR IN CONNECTION WITH THESE TERMS IN ANY 12-MONTH PERIOD WILL NOT EXCEED THE FEES THAT BUSINESS CUSTOMER PAID US IN THAT PERIOD. THESE LIMITATIONS APPLY TO CLAIMS FOR NEGLIGENCE OR ANY OTHER CAUSE OF ACTION TO THE FULLEST EXTENT PERMITTED BY LAW. SOME STATES DO NOT ALLOW THE LIMITATION OR EXCLUSION OF LIABILITY FOR CERTAIN DAMAGES, INCLUDING DAMAGES FOR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU, AND NOTHING IN THIS CLAUSE 14 IS INTENDED TO LIMIT LIABILITY WHERE THAT LIMITATION IS NOT PERMITTED BY LAW.

We provide the Service as a monitoring and alerting aid only, and do not accept liability for injury, loss, or damage arising from a failure of, or delay in, an alert being received or acted upon, from reliance on the Service instead of contacting emergency services directly, or from the acts or omissions of anyone the Service connects a User to, except to the extent caused by our own gross negligence or willful misconduct.

15. Force Majeure

We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including natural disasters, internet or telecommunications failures, or acts of government.

16. Children's Privacy (COPPA)

We do not knowingly collect personal information from children under 13. We rely on the age representation made under clause 4 when a User allocates a Friends and Family license, and we do not independently verify it. If we become aware that we have collected personal information from a child under 13 without the verifiable parental consent COPPA requires, we will delete that information promptly. A parent or guardian who believes we may have collected information from their child under 13 can contact us at [email protected] to request that we review and delete it.

17. Changes to These Terms

We may update these Terms from time to time. We will give Business Customers at least 30 days' notice of material changes, and will notify individual Users through the app or by email. Continuing to use the Service after a change takes effect means you accept the updated Terms.

18. Termination

We may suspend or terminate access for material breach of these Terms, including misuse of the Service, non-payment, or unlawful use, giving notice where reasonably practicable.

19. Governing Law

These Terms are governed by the laws of the State of Delaware, without regard to its conflict of laws principles, except that the Federal Arbitration Act governs clause 20. This choice of law does not deprive you of any consumer protection you are entitled to under the mandatory law of the state where you live, which continues to apply regardless of this clause.

20. Dispute Resolution: Arbitration Agreement and Class Action Waiver

PLEASE READ THIS CLAUSE CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.

20.1 Agreement to arbitrate. Except as set out below, you and Sentry agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration, administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court, except that either party may bring an individual action in small claims court.

20.2 Class action waiver. YOU AND SENTRY AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS.

20.3 Exceptions. This clause does not require arbitration of: a claim for injunctive relief to stop unauthorized use or abuse of the Service or infringement of intellectual property rights; or, as required by the federal Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act of 2021, a claim involving a sexual assault or sexual harassment dispute, which you may bring in court at your election instead.

20.4 Right to opt out. You may opt out of this arbitration agreement by emailing [email protected] within 30 days of first accepting these Terms, with your name and a clear statement that you wish to opt out of arbitration. If you opt out, neither you nor Sentry is bound by this clause 20, and disputes will proceed in the courts of Delaware.

20.5 Severability. If any part of this clause 20 is found unenforceable, the remainder remains in effect, and the affected part of the dispute will proceed in court rather than arbitration.

21. Your State Privacy Rights

If you are a resident of a state that provides consumer privacy rights, such as California, Virginia, Colorado, Connecticut, or Utah, see our Privacy Policy for how to exercise them.
