How Dynamic Sentry handles personal information on this website, through our contact form, and in the mobile apps we provide to our clients.
Last updated: 12 October 2026
Dynamic Sentry and Dyntri are trading names of Link Food Consultants Ltd, registered in England & Wales, company no. 14592222. Registered office: 17 Green Lane, Great Barr, Birmingham, B43 5JX.
In this policy, “we”, “us” and “our” mean Link Food Consultants Ltd. For any privacy question, or to exercise your rights, email support@dyntri.com or write to us at the registered office above.
Controller. For this website and for enquiries you send us, we decide how and why your information is used, so we are the controller under UK data protection law.
Processor. When we run software for a client (for example fleet compliance, transport management or temperature monitoring systems, and the mobile apps that go with them), we process the personal information in those systems on behalf of the client. The client, usually the employer, is the controller. If you are a driver or employee of one of our clients, your employer’s own privacy notice explains how your information is used, and you should contact them first. We will help them answer any request.
This website does not use cookies, and does not run analytics, advertising or tracking scripts. We do not build profiles of visitors.
The site is hosted on Cloudflare, which delivers the pages and protects the site against abuse. Like any web host, Cloudflare processes technical information such as your IP address, browser type and the pages requested, so it can deliver the site and keep it secure. Pages also load their styling library from a public content delivery network (Tailwind CSS, cdn.tailwindcss.com), which will see your IP address and browser details when it serves that file.
We rely on our legitimate interest in running a secure, working website for this processing.
When you use the form on our contact page, we collect:
How it is handled. Your submission passes through Cloudflare to our own server, and is then delivered to our director as a notification message through our own systems and messaging providers. We do not sell it, use it for marketing lists, or share it with anyone else, except where the law requires.
Your IP address is used only to limit how many messages can be sent from one address in an hour, to protect the form from spam and abuse.
Why we use it. To reply to your enquiry and take steps you ask for before any contract (and, more generally, our legitimate interest in answering business enquiries).
How long we keep it. Enquiries are kept for up to 24 months and then deleted, unless the enquiry leads to a customer relationship, in which case we keep the correspondence for as long as that relationship and our legal record-keeping obligations require.
We build mobile apps for our clients’ drivers, fitters and managers. They are used only by people a client has given an account to, and the information in them is processed on behalf of that client (see section 2). Depending on the app, this can include the user’s identity and sign-in details, the vehicle and job they are working on, the checks and records they complete, photos and signatures they capture, and, where an app uses it, location.
Information is sent securely to the client’s system, which we operate. We do not use app data for advertising, do not sell it, and do not include third-party advertising or analytics code in our apps.
Used by drivers to sign in to a vehicle, confirm their jobs, and record each delivery stop: arrival and departure, proof of delivery (signature, printed name, photos and quantities), exceptions, and scans of signed paper tickets. The app uses the phone camera for photos and scans. It does not access the phone’s location: vehicle position comes from the vehicle’s own tracking equipment, not the phone. The app can upload completed work in the background when the phone is offline and later reconnects.
Used by drivers for their weekly wheel torque check. The driver signs in with their workplace PIN, records each wheel hub checked and takes a photo. The app uses the camera for that photo.
A mobile version of our transport management console, for a client’s authorised managers. It shows the same information as the console, which can include driver records (such as licence and compliance details) and vehicle locations reported by vehicle tracking.
Used by tyre fitters to log in and record jobs, including the tyres fitted, photos and the job’s location (taken from the phone’s GPS when a job is recorded). Jobs can be saved on the phone while offline and sent when a connection returns.
Demonstrations and testing use generated data, not real people’s information. How long app data is kept is set by the client that controls it, in line with its own legal obligations (for example, transport record-keeping rules).
We run client systems on dedicated infrastructure that we manage, and we use a small number of service providers to operate them: hosting and network providers (including Cloudflare) and messaging providers that deliver notifications. They act only on our instructions. Some of these providers may process information outside the UK; where they do, we rely on the safeguards UK law requires, such as UK adequacy regulations or the International Data Transfer Agreement.
We never sell personal information.
Data in transit is encrypted. Access to our systems is restricted to authorised people, and app sign-ins are protected. No system is perfectly secure, but we take care to protect what we hold, and will notify the people affected and the ICO of a reportable breach as the law requires.
Under the UK GDPR and the Data Protection Act 2018 you have the right to:
To use any of these rights, email support@dyntri.com. We will reply within one month. If your information is held in a system we run for your employer, we will pass your request to them and help them answer it.
If you are unhappy with how we have handled your information, you can complain to the Information Commissioner’s Office (ICO) at ico.org.uk/make-a-complaint or on 0303 123 1113. We would appreciate the chance to put things right first, so please contact us.
We will update this page when the way we handle information changes. The date at the top shows when it was last revised.
