Welcome to Thirdfort's Privacy Policy
Last reviewed on 28 October 2026
We take privacy seriously and want to make it easy for you to understand what we do with your data. This privacy policy explains what information we collect, what we do with that information, who we share it with, and how long we keep it.
If you have any questions or comments about this Privacy Policy, or if you would like to exercise your data protection rights, please don’t hesitate to contact us:
by email at [email protected] or
by writing to us at c/o DPO, Belle House, Platform 1 Victoria Station, London, England SW1V 1JT.
Privacy Policy overview
This Privacy Policy explains what personal information is collected by us, Thirdfort Limited, a company registered in England and Wales with number 10757456 and registered office at Belle House, Platform 1 Victoria Station, London, England SW1V 1JT (“Thirdfort”, “we”, “us”, “our”) as part of our activities, and how we use that information.
Privacy Policy structure
To make it easier for you to review those parts of the Privacy Policy which apply to you, we have divided it up into the following sections:
Section 1 – General: This Section 1 applies to everyone who may visit the Thirdfort Website, use the Thirdfort Portal or the Thirdfort App, or otherwise interact with us.
Section 2 – Consumer: In addition to Section 1, Section 2 also applies if you are an individual who has downloaded and is using the Thirdfort App to carry out the verification requested by your professional advisor(s).
Section 3 – Thirdfort Clients: In addition to Section 1, this Section also applies if you are a solicitor, estate agent or other professional user making use of Thirdfort Services.
Accessing Thirdfort via a partner platform
If you are a Thirdfort Client accessing Thirdfort Services via one of our third party partners (listed at https://www.thirdfort.com/terms/partners), then the personal information that you provide in the course of accessing or using our services will also be subject to that partner’s privacy policy, in addition to this one.
Section 1: General
This section applies to everyone who visits or interacts with the Thirdfort Website, the Thirdfort Portal, or the Thirdfort App.
Personal Information we collect
When you visit the Thirdfort Website, email us, contact our Support team, or interact with us in general terms, we may collect:
your name
your email address and/or postal address
your phone number
your IP address
any additional personal information you share with us
We process this Personal Information:
to respond to your enquiries
to provide you with information about Thirdfort Services
to make our site better and make sure it is presented in the most effective way
to manage risk or prevent other illegal or prohibited activities
to resolve issues or fix problems on the Thirdfort Website, the Thirdfort Portal or the Thirdfort App
for internal operations, analysis, testing and research and to generally improve the services we provide
If you decide to contact us via a social media platform such as Facebook, LinkedIn or X (formerly Twitter) then you should be aware that you will be sharing your personal data and any information contained in your message via that social media platform. We interact with social media messaging platforms for inbound enquiries only and do not proactively share personal information with them. We endeavour to respond to social media enquiries via our other channels, typically email or over the phone.
Where we process Personal Information to provide a verification service requested by a Thirdfort Client, that client will generally decide why the check is required and act as controller, and Thirdfort will process the information to provide the requested service. Thirdfort may also process limited Personal Information as controller where necessary to operate, secure, protect against fraud or misuse of, investigate complaints about, and meet legal obligations relating to its services, and to develop, test and improve its services (see "How we use information from checks for our own purposes" in Section 2).
Legal basis for processing Personal Information
Our legal basis for collecting and using Personal Information will depend on the Personal Information concerned and the specific context in which we collect it.
However, we will normally collect Personal Information from you only where:
the processing is in our legitimate interests and not overridden by your data protection interests or fundamental rights and freedoms;
we have your consent to do so; or
we need the Personal Information to perform a contract with you.
In some cases, we may also have a legal obligation to collect Personal Information from you. If we ask you to provide Personal Information to comply with a legal requirement or to perform a contract with you, we will make this clear at the relevant time and advise you whether the provision of your Personal Information is mandatory or not (as well as of the possible consequences if you do not provide your Personal Information).
Who do we share your Personal Information with?
We will never sell your Personal Information. We may disclose your Personal Information to the following categories of recipients:
Our third party service providers who provide services to us, for example, to:
support the delivery of, provide functionality on, or help to enhance the security of the Thirdfort Website, the Thirdfort Portal or the Thirdfort App, or
process Personal Information for content customisation, personalisation, ad selection and delivery, reporting, and measurement purposes. This may also include our data analytics providers and cloud-based data processing and hosting providers. If we share this Personal Information with these parties, we will only do so insofar as it is reasonably necessary for the purpose(s) for which we have collected it.
Our third party service providers, as well as details about what types of information we share with them, can be accessed at https://www.thirdfort.com/terms/third-party-service-providers/.
Any competent law enforcement body, regulatory, government agency, court or other third party where we believe disclosure is necessary (i) as a matter of applicable law or regulation, (ii) to exercise, establish or defend our legal rights, or (iii) to protect your interests or those of any other person;
An actual or potential buyer of our business (and their agents and advisers) in connection with any actual or proposed purchase, merger or acquisition of any part of our business, provided that we inform the buyer they must use your Personal Information only for the purposes disclosed in this Privacy Policy;
Other relevant parties in order to enforce or defend our rights under an Agreement, or to protect the rights, property, or safety of Thirdfort, Thirdfort Client, Consumers, or others. This includes exchanging information with other companies and organisations for the purpose of fraud protection and credit risk reduction.
How do we keep your Personal Information secure?
We will take commercially reasonable, appropriate technical and organisational measures to ensure a level of security appropriate to the risk associated with the use of the Thirdfort Website, the Thirdfort Portal or the Thirdfort App, taking into account the likelihood and severity those risks might pose to your rights and freedoms.
In particular, we will take precautions to protect against the accidental or unlawful destruction, loss or alteration, and unauthorised disclosure of or access to the Personal Information transmitted, stored or otherwise processed by us. Please be aware that, while we make the security of the Thirdfort Website, the Thirdfort Portal and the Thirdfort App and your Personal Information a high priority and devote considerable time and resources to maintain robust IT security, no security system can prevent all security breaches. When you choose to share your Personal Information with us, you accept this and provide your information at your own risk.
Further information regarding our security can be found at: https://www.thirdfort.com/security-measures/.
Your data protection rights
You have the right to:
withdraw your consent to our processing of your Personal Information.
be told what Personal Information we hold about you on our database and how we process that data.
request that we provide you with a copy (in a commonly used electronic format) of all the Personal Information that we hold about you. Unless you make repeated requests which are manifestly unfounded or excessive, we will not charge a fee for providing you with a copy of this data.
request that we correct any inaccurate or incomplete Personal Information that we hold about you.
request that we irretrievably delete all Personal Information that we hold about you (the so-called “right to be forgotten”). Please note that there are limited circumstances in which we are legally entitled to refuse to comply with this request.
request that we transmit all the Personal Information that we hold about you (in a structured, commonly used and machine-readable form) to another organisation’s IT environment. Note that we are only legally obliged to comply with this request if it is technically feasible for us to do so.
opt-out of marketing communications we send you at any time. You can exercise this right by clicking on the “unsubscribe” or “opt-out” link in the marketing emails we send you, or by replying to any marketing text messages with the word “STOP”.

object to our processing of your Personal Information where we rely on our legitimate interests, including for the purposes described in “How we use information from checks for our own purposes”.
You can exercise any of the rights in 1–7, 9 and 10 above at any time by contacting us using our details set out at the beginning of this Privacy Policy.
We respond to all requests we receive from individuals wishing to exercise their data protection rights in accordance with Data Protection Laws.
Your right to complain
If you have any concerns about how we have handled your personal data, please tell us so we can put it right. You can contact us at [email protected], or by writing to c/o DPO, Belle House, Platform 1, Victoria Station, London SW1V 1JT.
We will acknowledge your complaint within 30 days, look into it without undue delay, keep you updated, and tell you the outcome.
If your complaint is about a check carried out for a Thirdfort Client, that client is usually the controller and the right organisation to handle it. We will still acknowledge your complaint, tell you who to contact and help the client respond.
If you are not happy with our response, you can also complain to the Information Commissioner's Office (ICO) at ico.org.uk/concerns or on 0303 123 1113. We would, though, welcome the chance to resolve it with you first.
Changes to this Privacy Policy
We may update this Privacy Policy from time to time in response to changing legal, technical or business developments, so please review it frequently. If we update our Privacy Policy and the amendments involve a material change to the way we collect, use, share, store or otherwise process your Personal Information then we will take appropriate measures to inform you, consistent with the significance of the changes we make.

You can obtain further information about data protection and privacy laws by visiting the Information Commissioner’s website at: https://ico.org.uk/your-data-matters.
Where we process personal data concerning those in the European Union, we have appointed IT Governance Europe Limited to act as our EU GDPR Representative. If you wish to exercise your rights under GDPR, or have any queries in relation to your rights or privacy matters generally, please:

Children’s privacy and age limitation
Thirdfort Services are strictly intended for individuals who are 18 years of age or older.
We do not seek or collect any personal information from anyone under the age of 18. If you are under 18, please do not use Thirdfort Services or share any personal information with us.
If we discover that we have accidentally collected personal information from a child under 18, we will take immediate and reasonable steps to delete that information from our records promptly. If you believe a child under 18 may have provided us with information, please contact us right away at [email protected].
Section 2: Consumers
This section describes what information is collected by Thirdfort from Consumers, how that information is used by Thirdfort, and for how long Thirdfort keeps the information. You are a Consumer if you have been invited to provide Personal Information to Thirdfort so that we can carry out verifications on you for the benefit of the Thirdfort Client (i.e. professional advisor(s) you engaged), and this section will apply to you.
This Privacy Policy applies to Digital Right to Rent Checks carried out through Thirdfort services. If you are completing a check through the separate Homeppl tenant referencing service, the Homeppl Privacy Policy made available to you will apply instead.
What Personal Information do we collect from Consumers?
When you share information with us in the Thirdfort App we will ask you to provide some or all of the following Personal Information, depending on the type of request that the Thirdfort Client has made:
your full name
your email address
your address
your telephone number(s)
your date of birth
information specific to your transaction (e.g. details of the property you are buying or selling)
employment information (e.g. employer, occupation, how long you have worked there)
photographic proof of identity (e.g. passport, driving licence, identity card)
where a Digital Right to Rent Check is requested, your British or Irish passport or Irish passport card details and image, and the photograph or short video (selfie) needed to verify your identity
biometric data (e.g. photo, liveness video, audio)
financial personal details (e.g. bank details, transaction details, account balance information)
Thirdfort does not intentionally collect or process health data as part of our core services. Where you voluntarily disclose such data when interacting with us for support purposes, we may process it based on your explicit consent. We will use this data only for the specific purpose of addressing your request, providing support, or meeting related legal obligations, and it will be treated confidentially.
What do we do with the Personal Information that we collect from Consumers?
We will process the information that we have collected for the following purposes:
to enable you to use the Thirdfort App to fulfil a request made by a Thirdfort Client.
to perform our contract with Thirdfort Clients for the provision of ID verification, Know Your Client (KYC) and Anti-Money Laundering (AML) checks.
to conduct source of funds checks using open banking data technology to access and analyse your financial and banking information.
to cross reference your banking information and salary payments with your employer and employment history.
to enable you to share your personal information with any third parties that you designate, e.g. if you instruct a solicitor then you may choose to provide the solicitor with access to your information.
to respond to your enquiries and provide assistance.
to perform a Digital Right to Rent Check where this has been requested by a landlord, letting agent or other organisation, including verifying your identity, carrying out a passive Known Fraud check and providing the resulting report to that organisation.
How we use information from checks for our own purposes
As well as carrying out checks for Thirdfort Clients, we use some information from checks as a controller for our own purposes:
to detect and prevent fraud and financial crime, including by recognising fraud patterns across our clients and services;
to develop, test, evaluate and improve our products, services and technology, including our tools for checking whether documents are genuine and for reading information from them; and
to invite you to take part in optional, occasional research about your experience of our App. Taking part is voluntary, you can opt out at any time, and we don't use it for marketing.
Where we can, we use pseudonymised or minimised information for these purposes. We keep information used to develop and test our tools only for as long as we need it for that purpose, in line with our retention schedule. Our AI providers are not permitted to use your information to train their own models.
We rely on our legitimate interests in preventing fraud and in developing and improving our services. Where a check suggests that a document may be false or that fraud may have taken place, this may be information about suspected criminal activity. We use it only where permitted by the Data Protection Act 2018 for preventing or detecting unlawful acts and preventing fraud.
You can object to our use of your information for these purposes by contacting [email protected].
Use of automated tools and AI
We use automated tools, including artificial intelligence and machine learning (AI), to carry out and support the checks requested by the Thirdfort Client. For example, we use them to read and verify identity documents, compare your photo or video with your identity document, analyse financial and bank data, screen against sanctions, politically exposed persons (PEP) and other watchlists and review potential matches, and help produce the outcome of your check.
The outcome of your check is provided to the Thirdfort Client, who decides how to use it. You can ask for a person to review the outcome of an automated check, give your point of view and challenge the outcome by contacting us at [email protected].
Our AI providers are contractually prohibited from using your Personal Information to train or fine-tune their models. Some of our identity verification providers may use limited data to improve their own services, acting on their own behalf, as described in their own privacy terms.
Who do we share Consumers’ Personal Information with?
Your professional advisor
We will share your Personal Information with the Thirdfort Client(s) you have engaged. The Thirdfort Client is likely to be the solicitor, estate agent or other adviser who requested that you download the Thirdfort App and will be named in SMS invite messages from Thirdfort. Within the Thirdfort App it is clearly indicated at the top of your tasks list the Thirdfort Client that requested the tasks.
Our partners
If the Thirdfort Client has purchased Thirdfort Services via one of the Thirdfort Partners listed at https://www.thirdfort.com/terms/partners/, then we may share your Personal Information with that Thirdfort Partner to the extent reasonably necessary in order for us to provide the Thirdfort Services.
Third party service providers
We may also share your Personal Information with third party service providers, including identity verification, biometric and liveness verification, fraud prevention and fraud database, open banking, credit reference and reporting providers, where necessary to provide the requested Thirdfort Services. This includes Entrust, which provides identity verification services previously branded as Onfido. These providers may check your Personal Information against databases available to them to verify identity or help prevent fraud, and may keep a record of the search where permitted by law and their applicable privacy terms.
We share Personal Information only to the extent reasonably necessary for the purposes described in this Privacy Policy. Details of our third party service providers and the types of information shared with them are available at https://www.thirdfort.com/terms/third-party-service-providers.
Digital Right to Rent Checks
Where a landlord, letting agent or other organisation asks you to complete a Digital Right to Rent Check in England, we use your eligible identity document and a photograph or short video of you to verify your identity. Where we use biometric data to verify your identity, we will ask for your explicit consent in the Thirdfort App before carrying out that processing. If you do not provide or withdraw that consent, the digital verification route may not be available and the requesting organisation may need to use an alternative prescribed route. We may also carry out a passive Known Fraud check using fraud prevention providers and databases. If completed, we will provide the requesting organisation with the identity information, images, date and verification report required for that digital check. We do not decide whether you have a legal right to rent a property. The requesting landlord or agent is responsible for its Right to Rent decision, for confirming that you are the person whose identity was verified, and for retaining the report as required by law. If the digital route cannot be completed, this does not necessarily mean that you do not have a right to rent; the requesting organisation may need to use another prescribed route. Some identity verification stages use automated matching. You can ask for help or raise a concern about the check by contacting [email protected] or [email protected].
Your confirmation
Before we start a Digital Right to Rent Check, we will ask you to confirm in the Thirdfort App that you want to go ahead. We will not share your check with the requesting organisation unless you confirm. Your confirmation gives you control over the check and who receives it. It is not the legal basis for our use of your Personal Information, except where we ask for your explicit consent to use biometric data, as explained above.
Our legal basis for Digital Right to Rent Checks
We carry out a Digital Right to Rent Check on behalf of the landlord, letting agent or other organisation that asked you to complete it. That organisation is the controller, decides why the check is needed and relies on its legitimate interests in establishing a statutory excuse. It is responsible for telling you its legal basis.
We also use some of your Personal Information for our own purposes as a certified digital verification service provider. For these purposes we rely on:
your explicit consent, to use your biometric data (your photograph or short video) to verify your identity. You can withdraw your consent at any time, but the digital route will then not be available and the requesting organisation may need to use another prescribed route;
our legitimate interests, in preventing fraud and identity misuse (including the passive Known Fraud check) and keeping our service secure; and
legal obligation, where we must keep records or meet other legal requirements that apply to us.
Transfers outside the United Kingdom
Our servers, with Google Cloud Platform, are located in England and the Personal Information that we collect directly from you will be stored on these servers. We may also transfer your Personal Information to one or more of our third party service providers listed at https://www.thirdfort.com/terms/third-party-service-providers, some of which may be located outside of the UK or EEA, appoint subprocessors outside the UK or EEA, or operate from multiple locations (including non-EU locations). If the Thirdfort Client is located outside the UK or EEA then we may also transfer your Personal Information to them.
We take all steps reasonably necessary to ensure your Personal Information is processed securely and in line with this Privacy Policy as well as the Data Protection Legislation. We will only transfer your Personal Information to third parties outside the UK if:
it is located in a country confirmed by the UK government to provide adequate protection to personal data;
a contract is in place to protect the personal data as required under Data Protection Legislation. This may include standard data protection clauses adopted by a data protection regulator and approved by the European Commission, such as the European Commission’s standard contractual clauses; or
we have another legal basis for doing so.
How long do we keep Consumers’ Personal Information?
We will store your Personal Information only for the period of time that is necessary to conduct the relevant checks and provide Thirdfort Services to the Thirdfort Client in line with our contract with them. We keep the Personal Information shared with us directly only for as long as we need it for the relevant checks and the other purposes described in this Privacy Policy, in line with our retention schedule. Where we use information for our own purposes (see "How we use information from checks for our own purposes"), we keep it in line with our retention schedule for those purposes.
The organisation that requested a Digital Right to Rent Check is responsible for retaining the report it receives for its own statutory Right to Rent record keeping. Thirdfort does not hold that report as the requesting organisation's statutory archive, but may retain a limited record where necessary to provide the service, manage fraud and security, deal with complaints or disputes, and meet legal obligations.
Upon request by a Thirdfort Client or when we or any of our third party service providers no longer need to process the Personal Information, we will cease to process it and it will be deleted, unless retention is required by applicable law.
Section 3: Thirdfort Clients
This section describes what information is collected by Thirdfort from Thirdfort Clients, how that information is used by Thirdfort, and for how long Thirdfort retains the information. You are a Client if you use Thirdfort Services to carry out verifications on your clients, and this section will apply to you.
