Privacy notice
Last updated 29 October 2026. This notice covers deadlio.co.uk, including the company checker, the strike-off checker the new companies email and the Deadlio Sense Chrome extension, including Time capture.
deadlio.co.uk is a fintech product of MGT Fintec Synergies Ltd, a company registered in England and Wales (company number 10628094), registered office C/O Cloud Business Hub, 23 Sangley Road, London SE25 6QT. We are the data controller for the personal data described here.
Contact us about privacy at updates@deadlio.co.uk.
You can search for companies without signing up or giving us any personal details. To stop misuse, our server counts how many lookups come from each visitor in an hour. It does this with a scrambled (hashed) version of your IP address that is deleted after an hour and cannot be turned back into the address.
Fonts are loaded from Google Fonts, which receives your IP address when the page loads.
If you sign up, we keep:
We use these only to send you the list of newly registered companies in your postcodes, at the frequency and time you chose.
Our lawful basis is your consent. You confirm by clicking the link in the first email we send. If you do not confirm, we delete your details within 7 days.
You can unsubscribe at any time using the link at the bottom of every email. We then delete your details. Each email includes one clearly labelled sponsored message from a business advertising in your area. We do not share your email address with advertisers; we only count clicks on the message.
You can add Deadlio to your phone's home screen and, if you choose, turn on alerts for a postcode district (for example SE25). Nothing is turned on unless you tap the button and then allow notifications when your phone asks.
If you turn on alerts, we keep:
We do not ask for, and do not keep, your name, email address or phone number for alerts. We send at most one alert a day per district, only when there are new companies or strike-off applications there.
Our lawful basis is your consent. You can turn alerts off at any time with the "Turn off" link on the district page, or in your browser or phone settings. When alerts are turned off, or your phone tells us they no longer work, we delete the push address.
Alerts are delivered by the push service that belongs to your browser or phone (Google for Chrome and Android, Apple for iPhone and Safari, Mozilla for Firefox, Microsoft for Edge). Each alert is encrypted so that only your device can read it.
The app remembers the last district you looked at, and whether you closed the "Add to home screen" message, in your own browser only. We also count, without identifying you, how often the message is shown and how many people add the app or turn alerts on or off.
Company details, filing dates and financial figures come from the public register at Companies House. This can include the names and addresses that companies have filed. We show this public information under the Open Government Licence v3.0 so that directors, accountants and others can check filing deadlines. If any of it is wrong, it needs to be corrected at Companies House.
The list of companies that applied to strike off comes from the same public Companies House filings. If you click "Use my location", your browser's approximate position is sent to postcodes.io, a free public postcode service, to find your postcode district. We do not store your location.
On a company page you can ask us to email you a free Penalty Exposure Report for that company. We use your email address only to send that one email – we do not store it or add it to any list unless you tick one of the boxes below the form. If you tick the box for weekly new-company emails, we send a separate email asking you to confirm, as for any other sign-up. The report may include one sponsored message from a business advertising in that area; clicks on it are counted without identifying you.
We may also send a one-off report to the business email address of a company whose filings are overdue on the public Companies House register. For these we keep a record of the address, the company and when we sent it, whether the email could not be delivered, and when someone clicks a link in a report we send (so we know whether it was useful). We do not use tracking images. You can stop these emails at any time with the unsubscribe link in the email or by replying STOP, and we will not email that address again.
If you tick “Email me reminders before this company’s accounts and confirmation statement are due”, we send you an email asking you to confirm. Once you confirm, we keep your email address, the company number and name, the date you signed up and confirmed, the wording you agreed to, and which reminders we have sent. We use this only to email you 30 days and 7 days before each of those deadlines, and once if a deadline is missed. Every reminder has a one-click unsubscribe link, and unsubscribing deletes your details for that company. Sign-ups that are not confirmed within 7 days are deleted, and so are reminders for companies that are dissolved. We do not share your details with anyone.
If you buy a Penalty Appeal Pack, we keep a record of the order: the company number, the reason you chose, your email address, the date of payment and how many times the pack was downloaded. We use your email address to send your download link and to deal with any problem with your order. Payment is handled by Stripe – we never see your card details. We keep order records for six years for our accounts, and we do not use your email for marketing.
If you buy a Strike-off Objection Pack, a Restoration Pack or a Company Check report from Deadlio Lab, we keep a record of the order: the product, the company number, the option you chose, your email address, the date of payment and how many times it was downloaded. We use your email address to send your download link and to deal with any problem with your order. Payment is handled by Stripe – we never see your card details. We keep order records for six years for our accounts, and we do not use your email for marketing.
The Company Check report includes information about people from the public Companies House register: the names and roles of the company’s current and former directors, the other companies each director is or was appointed to, the people with significant control and the nature of their control, and any entry for a director on the register of disqualified directors. We reuse this under the Open Government Licence v3.0, and our lawful basis is legitimate interests – helping buyers check a company before they deal with it. To match a director to the disqualified directors register we compare their name with their month and year of birth from the register; we do not print the date of birth in the report. We keep this information for no longer than 7 days, so that each report reflects the register at the time.
If you are a director and do not want your details included, email updates@deadlio.co.uk with your company number and we will exclude them.
Our two paid downloads – newly registered companies, and companies that are late with their accounts – include the names and roles of each company’s directors (for example "SMITH, John (Director)"). We take these from the public Companies House register and reuse them under the Open Government Licence v3.0. We pass them only to signed-in business customers, so they can offer their services to those companies; our lawful basis is legitimate interests. We do not include dates of birth, nationality or addresses, and we keep directors' names for no longer than 30 days.
If you are a director and do not want your name included, email updates@deadlio.co.uk with your company number and we will exclude it.
If you install the Deadlio Sense extension for Google Chrome (Company Watch and Sense time capture), it keeps the companies you choose to watch, your settings and how many free searches you have used today. These stay in your browser and, if you use Chrome sync, in your Google account. Unless your employer switches on Time capture (see below), we do not receive your browsing history and the extension does not read the pages you visit, except the company number in the address of Companies House company pages, so it can show that company's deadlines. If your employer also uses the Client finder, see the next section.
To show deadlines and send reminders, the extension sends company numbers and the words you search for to deadlio.co.uk. We use them only to answer the request, in the same way as a search on this website (see Looking up a company). Reminders are shown by Chrome on your computer: we do not send them and we do not need your email address for them.
If you sign in to the extension, we keep your email address, the practice you belong to and a sign-in token, and we record when the extension last checked in. Sign-in is by an emailed link; we do not use passwords.
The extension does not use cookies, advertising or analytics. You can remove everything it stores in your browser by removing the extension from Chrome. More about the extension.
Deadlio Sense Time capture is a service for employers (practices). It is off unless a practice owner switches it on for their practice. When it is on, the practice, not Deadlio, decides that its staff's working time is recorded and why: the practice is the controller of those records and Deadlio is its processor, under a data processing agreement the practice accepts before recording starts. The practice must give its staff a notice explaining the recording; we provide one, filled in for the practice.
For each staff member being recorded, during the practice's working hours only, we receive and keep:
We never receive page content, emails or files, anything typed, form entries, passwords or screenshots, and nothing outside working hours. Staff always see "Recording" in the extension, and a green ON on its icon, while recording is active.
Client finder. Some systems (for example bookkeeping ledgers, payroll and audit software) do not show the client in the page title. If the practice switches on the Client finder (Sense Pro) and the staff member allows it in Chrome, the extension checks the page in use, on the staff member's own computer, for the practice's own client names, numbers, email addresses, domains and codes. The page itself is never sent to us or stored: only the client found and the identifier that matched are recorded. Form fields, anything being typed and incognito tabs are never checked.
The practice also gives us its client list (names, company or reference numbers, email addresses, codes and fees) so time can be matched to clients.
Records are stored encrypted, can be seen only by the practice's owner and admins, cannot be changed by staff, and are deleted automatically after the retention period the practice sets (2 years by default). When a practice stops using Time capture we delete its data within 90 days unless it asks for a copy first. We use the records only to provide the service to the practice; we do not sell them, use them for marketing or share them with anyone else.
The desktop helper runs only on the computer where it is installed and talks only to the Deadlio Sense extension there. It reads the name and window title of the program in front and how long since the mouse or keyboard was used.
If you are a staff member and want a copy of your records, to have them corrected, or to object, contact your employer first: they control the records and can export them in one click. You can also email updates@deadlio.co.uk and we will pass your request to them.
We do not sell your data or share it with anyone for their own marketing. If any of our providers stores data outside the UK, appropriate safeguards required by UK data protection law are in place.
If you ask us to email you the link to the Deadlio Chrome extension, we keep your email address only to send that one email. If the extension is not yet available, we hold it until it is and then send the link once. We do not add you to any mailing list. You can ask us to delete it at any time.
Under UK data protection law you can ask to see the information we hold about you, have it corrected or deleted, or withdraw your consent at any time. To do any of these, email updates@deadlio.co.uk.
If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk.
