This notice is Version 5, and was last updated on 25 Jan 2023.

We may change this notice from time to time, so please check this page occasionally to make sure you are happy with any changes.

We are committed to respecting your privacy and information that could identify you as an individual (‘personal data’). This notice describes the personal data we may collect about you, how we use and secure it, who we may share it with, and your rights in respect of such personal data.

Who are we?

We are Diffblue Limited, experts in artificial intelligence that understands code. We are a company registered in England and Wales number 09958102, with our registered office at 16c Worcester Place, Oxford, OX1 2JW, England. Unless stated otherwise, we are the controller of the personal data described in this notice.

How do we collect personal data?

We collect and combine personal data from the following sources:

Information you provide to us

You may provide us with personal data by filling in forms on our website, submitting information to one of our product or service portals, meeting with us, or contacting us via post, telephone, email, chat or other form of communication.

Information we collect ourselves

When you visit our websites or portals, we may automatically collect information about the device you are using and the way that you use such site or portal.

Information we receive from others

We may receive personal data from publicly available sources and other organisations such as advertisers, suppliers, service providers, trade agents and resellers. For example, as part of our recruitment processes, we may receive information from recruitment service providers, employment background screening agencies and your named referees. We may also search job sites and professional networking sites such as LinkedIn to find potential candidates for job vacancies.

What personal data do we collect?


Personal data collected might include items such as your name, email address, date of birth, gender, job title, contact details, IP address, device ID, and any correspondence that you have with us. If you make a purchase from us, we will collect your payment details.


If we consider you for a job vacancy, we will keep a record of your progress through our hiring process. We may also ask you to provide work and educational history, information about your skills and experience, and proof of your right to work in the relevant country. You are not required to provide all requested information, but failure to do so may result in us being unable to proceed with your candidacy for a role.

How do we use your personal data?

Our usage will be based on performance of our contract with you, compliance with our legal obligations, protection of your health (or the health of another person) in an emergency, pursuance of our legitimate interests (provided that these are not overridden by your rights, freedoms and interests), your consent, or another purpose permitted by law. Some examples are given below.


We may use third party advertisers to serve adverts on our behalf across the internet. The advertisers may use cookies and other tracking technologies to record the referring webpage and to measure and report on the effectiveness of those adverts.

Cookies and tracking

Our websites and portals may use cookies and other tracking technologies to distinguish you from other users and tell us whether you are a repeat visitor, whether you have seen the cookie information banner, whether you have accepted our terms and conditions, which pages you visited and how long you stayed on certain pages. This helps us to provide you with a good experience when browsing (for example by not showing a page or banner that you have already seen recently), generate usage statistics, assess and improve our content, and display interest-based advertising on our pages. We may also generate reports when we experience errors on our websites and portals in order to enable us to diagnose and correct those errors (such as which browser type was being used when the error occurred). You may adjust the settings on your browser to refuse cookies, but some of the services on our websites and portals may not work if you do so. For more information, please see our cookie statement.


We may send you information about our products and services. Where required by law, we will obtain your consent before contacting you. You can ask us to stop sending you marketing communications at any time by clicking on any unsubscribe options in the communications that you receive. We do not sell or rent personal data to third parties. We may track whether communications were delivered or undelivered, opened, marked as spam, and whether you unsubscribed or clicked on any link within them in order to monitor the effectiveness of our campaigns, keep our mailing lists up-to-date, manage your preferences and deliver content that is most relevant to you.


We may use your personal data to provide the products and services you requested, manage your account, and send you notices and correspondence about your account. We may also use your personal data for the purposes of billing, payment, fraud detection, forecasting, product roadmap and lifecycle planning, trend analysis and financial reporting.

Customer support

If you contact us to report problems or ask questions about our products and services, we will record details of our interaction with you in our support ticket management system. We may use this information to respond to your request, improve our existing products and services, research and develop new products and services, troubleshoot and remedy issues with our products and services, monitor trends, monitor support response times and effectiveness, seek feedback about our products and services, monitor customer satisfaction, and provide staff training.

On-site or remote access to your data

If we come to your site or otherwise access your systems and data to perform installation, training, consultancy support, and other services, we may have incidental access to your personal data. In this case, you will be the controller and we will act as your processor. We will comply with your reasonable instructions to maintain the authenticity, confidentiality, security and integrity of your personal data.

Open source submissions

If you contribute code to our open source projects, we may record your name, email address and details of your submission in our code repositories, company records and in publicly available notices that are included with the code in order to manage code changes and intellectual property.

Security monitoring

We may log personal data while monitoring our company systems, data and equipment for the purposes of threat detection and prevention, investigating and remedying security incidents, and ensuring lawful use of such systems, data and equipment.


We may use your personal data to enforce our terms and conditions and to carry out checks aimed at preventing illegal activities such as export and trade sanction violations, bribery, fraud, corruption and modern slavery. We may also maintain compliance records and report on the steps we have taken to auditors and authorities.


We may use the personal data that we collect during the recruitment process for evaluating your suitability for current and future employment opportunities, record keeping in relation to recruiting, and improving our recruitment processes.

Who else may access your personal data?


We may share your personal data with service providers and suppliers who process personal data on our behalf in the course of providing their goods and services. For example, if we consider you for a job vacancy, we use a cloud-based, third party recruiting platform and may also be assisted by third party service providers for processes such as employment background screening. We will also share your personal data with those persons involved in the interview and selection process. We include data protection provisions in our contracts and verify the security measures of these service providers and suppliers in order to safeguard your personal data during processing.

Other controllers

We may also share your personal data with courts and other organisations where necessary to comply with legal obligations (for example in response to a court order) or to exercise or defend our legal rights, tax and social security authorities, group companies, insurers, lawyers, accountants, auditors, professional advisors, and buyers investors or transferees of our business or parts of our business. If you apply for a job via a third party (such as a job site or recruitment services provider), we may inform them of the progress of your application and (where applicable) any other information necessary for them to calculate their referral fee.

Where is your personal data located?

Your personal data may be processed outside of the European Economic Area (EEA), including in countries with less protective data protection laws. In such circumstances, we take appropriate steps to safeguard your data to EEA data protection standards, for example by entering the European Union’s standard contractual clauses or selecting organisations with the Privacy Shield certification. For more information or to request copies of the standard contractual clauses, please contact [email protected].

How long do we keep your personal data?


We retain personal data for as long as necessary for the purpose for which the personal data was collected, or for such longer period required by law or otherwise necessary to defend or exercise our legal rights. At the end of this period (or expiry of our backup archive retention period if later), we will either delete or anonymise the personal data.


If you accept an offer of employment with us, any relevant personal data collected during the recruitment process will become part of your personnel records. In other cases, we will retain your recruitment information on file for a period of up to 12 months. At the end of this period, we may contact you to ask if you would like us to retain the information for a further period.
