Last updated: 22nd June 2026

Introduction

The Sentry Devices Ltd ("Sentry", "we", "us", "our") of 173 King Street, Ramsgate, Kent CT11 8PN are committed to protecting and respecting your privacy. We are committed to the protection of the personal data we process in line with the data protection principles set out in the UK General Data Protection Regulation ("UK GDPR") and the Data Protection Act 2018.

This privacy notice ("this Notice") explains what personal data we collect from individuals who visit our website, use our app, contact us using our web forms, by email, phone or through one of our social channels; or other marketing communications ("you", "your"). It also explains what information we collect automatically when you visit our website and the information we collect when you register to use our services.

The Sentry Devices Ltd is the Controller of the personal data we collect, registered in the UK with the Information Commissioner's Office ("ICO"), registration number ZB520206.

As an information-led business, we place great importance on ensuring the quality, confidentiality, integrity, and availability of the data we hold and in meeting our data protection obligations when processing personal data. We are committed to protecting the security of your personal data. We use a variety of technical and organisational measures to help protect your personal data from unauthorised access, use or disclosure.

We update this Notice from time to time in response to changes in applicable laws and regulations, to our processing practices and to the products and services we offer. When changes are made, we will update the date at the top of this document. Please review this Notice periodically to check for updates.

The Sentry App Platform

The Sentry lone worker safety app and its associated business administration portal are operated at business.thesentry.co.uk by a separate specialist technology provider on behalf of The Sentry Devices Ltd. That platform operates under its own privacy policy, which is published at business.thesentry.co.uk/privacy-policy. The Sentry Devices Ltd is not responsible for the privacy practices or data processing activities of that platform. We strongly encourage you to read its privacy policy before registering for or using the app.

This Notice covers only the data collected through our marketing website at thesentry.co.uk, including our contact and enquiry forms, analytics, and any direct correspondence with us.

What Personal Data Do We Process?

Information you provide to us

We process all information you give us, either through our website thesentry.co.uk or by corresponding with us by telephone, email or otherwise. This includes information you provide when you use our site, app, our social media functions, register for our service, search for a product or service, or when you report a problem with our site or app.

We may process the following information:

  • Name
  • Address
  • Email address
  • Location data
  • Video footage
  • Any information you share with us using our social media channels
  • Device information

Minimum Age

The Sentry is a professional business service designed for use by adults in a commercial employment context. Our platform is not intended for use by individuals under the age of 18. We do not knowingly collect personal data from anyone under 18 years of age. If we become aware that personal data has been submitted by someone under 18, we will delete it promptly.

Cookies and Analytics

Our website uses cookies to improve your experience and to understand how visitors use our site. On your first visit, our cookie consent banner asks for your permission before any optional cookies are set. You may accept or decline at any time using the Cookie Settings link in the footer.

We use Google Analytics 4 (GA4), loaded via Google Tag Manager, to collect anonymised data about how visitors interact with our website — including pages visited, time on site, and general geographic region. We do not use GA4 for advertising or remarketing. To protect browser performance, Google Tag Manager scripts are sandboxed and run in an isolated worker thread via a privacy-preserving technique called Partytown, meaning they do not run directly in your main browser session. Analytics cookies are optional and are only activated with your consent.

Strictly necessary cookies are set without consent as they are required for the website to function (for example, to remember your cookie preference). No personal data is stored, saved or collected via strictly necessary cookies.

The law states that we can store cookies on your device if they are strictly necessary for the operation of this site. For all other types of cookies, we require your consent.

Purposes and Bases for Using Your Personal Data

We will process your personal information for the following purposes and under the following lawful bases:

Purpose Lawful Basis for Processing
Responding to correspondence from you. It is in our legitimate interest to respond to enquiries made via our website, by email, through our social channels or any other means.
Registering your interest or making a purchase. When you register your interest or make a purchase, we process your data either with your consent, or under the contract of sale. Consent may be withdrawn at any time by emailing privacy@thesentry.co.uk.
Business management, forecasting and statistical purposes. It is our legitimate interest to identify areas for managing current business relationships, develop our services and for managing our business.
Improving our website and the overall website visitor and user experience. It is our legitimate interest to allow analytics and search engine providers to help improve and optimise our website. We also use cookies on our website with your consent.
Prevention and detection of crime including money laundering, fraud or other crimes. We have a legal obligation to report any such activity to the relevant authorities and regulators.

We may also process any of your personal data where such processing is necessary for compliance with a legal obligation to which we are subject, or to protect your vital interests or the vital interests of another natural person.

Third-Party Service Providers

We work with a small number of carefully selected third-party service providers to operate our website and deliver our services. Each provider acts as a data processor on our behalf and is contractually required to protect your personal data in accordance with UK GDPR. The providers we currently use are set out below.

Provider Purpose Data processed
Google Analytics 4 / Google Tag Manager Website analytics — understanding how visitors use our site so we can improve it. Anonymised browsing data (pages visited, session duration, approximate geographic region). Only activated with your cookie consent.
Google Firebase Hosting Our marketing website (thesentry.co.uk) is hosted on Google Firebase infrastructure. Standard web server logs (IP address, browser type, pages requested). Logs are retained for a short period for security purposes.
Resend Transactional email delivery — sending you a confirmation when you submit an enquiry or book a demo via our website. Name, email address, and the content of your enquiry submission.
Stripe Payments UK Limited Payment processing for annual subscription purchases. Payment card data and billing information. Sentry does not store or have access to your card details — all payment data is handled entirely by Stripe.

Sharing Your Information

We do not sell, rent, or trade your personal data to any third parties. We will not share your personal data with service providers located in countries outside the UK where the data protection laws are not equivalent to those within the UK. Should this become an operational necessity in the future, we will safeguard any such data transfers using the UK-approved International Data Transfer Agreement, which contractually obliges our business partners in those countries to protect your data to the standard expected within the UK.

Your Rights

The UK GDPR provides you with certain rights in relation to the processing of your personal data, including to:

  • Request access to personal data about you (a "data subject access request"). This enables you to receive a copy of the personal data we hold about you, and to check that we are processing it lawfully.
  • Request rectification, correction, or updating to any of the personal data that we hold about you. This enables you to have any incomplete or inaccurate information we hold about you corrected.
  • Request portability of personal data provided by you, to be transferred in machine-readable format.
  • Request erasure of personal data. This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove personal data where you have exercised your right to object to processing.
  • Request the restriction of processing of your personal data. This enables you to ask us to suspend the processing of personal data about you (e.g., if you want us to establish its accuracy or the reason for processing it).
  • Object to the processing of your personal data in certain circumstances. This right may apply where the processing of your personal data is based on our legitimate interests.

Some of these rights are not absolute and are subject to various conditions under applicable data protection and privacy legislation, laws, and regulations to which we are subject. If at any time you decide that you no longer wish to be contacted for marketing purposes, or if you would like to exercise any of your rights as set out above, you can contact privacy@thesentry.co.uk.

You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request for access is clearly unfounded or excessive. Alternatively, we may refuse to comply with the request in such circumstances.

In addition to the above, please note that you have the right to make a complaint at any time to the Information Commissioner's Office if you are concerned about the way in which we are handling your personal data. You can contact the ICO at ico.org.uk.

Data Retention Period

We will retain your personal data for as long as is necessary to provide you with our ongoing services and for a reasonable period thereafter, to enable us to meet our contractual and legal obligations.

At the end of the retention period, your personal data will be securely deleted in accordance with our Personal Data Retention Policy.
