Privacy Notice

At Lister we are committed to protecting and respecting your privacy. This policy outlines details of the information that we collect, store and process, and the measures we take to protect and safeguard this information. We always welcome suggestions to improve our information governance, privacy, and cyber security policies and procedures.


Who are we?

Clinical Task Systems Limited (trading as “Lister”) is a limited company registered in the UK (Company number 10839792) with registered address 57 Jordan Street, Liverpool, Merseyside, United Kingdom, L1 0BW. For the purposes of this privacy policy Lister is the ‘Data Controller’ and assumes that role under UK and European Law.


How your information is used

If you register your email address will be used to obtain further information from you. We will also use your email to contact you with suitable surveys, job opportunities and updates from Lister only if you give us express permission to do so. This may include details of new features and updates to the application. Our processing basis for this communication is Consent, which you will be requested for at the time you submit a form.


How long do we hold data for?

Any personal data which you have provided to us, except in registering and user the Lister task management platform, will be deleted after a period of 12 months, or earlier if the we no longer have need of the data or if the terms of your consent to give us the data express more restrictive limitations on holding the data. Personal data provided to us as part of your registration and use of the Lister clinical task management platform must be held for at least 8 years after your last active use of the platform, but would only be used if it is requested of us legitimately in the context of a patient safety incident or legal investigation. As soon as you no longer have an active account on the Lister platform, we will cease processing or accessing your data for any other purpose.

Lister only retain data for as long as it is strictly required. This means data that you provide through the contact form is held for 12 months. After this time all stored data will be removed from our live systems. Prior to removal we will attempt to contact you to inform you.

In order to operate a reliable system and to avoid data loss we perform regular encrypted backups of the system. These backups are retained for up to 90 days, and after this time are removed. This means that a removed account will be completely removed from all backups 90 days after removal. Data related to patient clinical information will be retained for 8 years.


Who has access to your data?

Lister will never sell or share personal data related to you or any clinical/health data inputted into the Lister task management system.

Lister will not sell or rent your information to third parties, and we do not share information for marketing purposes with any third parties.

Lister may share some personal data with 3rd party partners working on our behalf – this includes contractors & workshop providers who work with Lister to provide services. Where such a relationship is in place there are contractual safeguards in place to protect your information. Lister will only share data that is relevant to the tasks being completed and to the delivery of service to you, and where possible the data will be anonymised. None of these organisations and individuals are permitted to use the data for any other purpose. We will never share any clinical or health data inputted into the Lister task management system with any 3rd party provider, unless we are entirely satisfied that those providers adhere to industry best practice for information governance and cyber security. Typically, we require such providers to be independently certified against a recognised standard, such as ISO 27001.

At any time you will be free to remove consent by contacting us at


How will we keep your data secure?

Lister has been designed with a privacy first development methodology meaning that we follow a rigorous development process which places the security of personal information at its core. To that end we host our application and website using a GDPR compliant cloud data provider hosting the application and site in the UK. We use AWS as our cloud provider, and AWS are certified against ISO 27001 and have a published NHS Digital Data Security and Protection Toolkit score of “Exceeds Requirements”. All of our services run over HTTPS using TLS ensuring data transmitted between the application/website and our servers is secure. Data you provide to us which is stored is encrypted when it is stored, and in any backups taken. We take lengths to ensure that the network environment in which the application/website is hosted is kept secure by following best practices and ensuring that security updates are applied in a timely fashion.

Lister is independently certified against the Cyber Essentials and Cyber Essentials Plus standards. The Lister task management platform undergoes yearly independent cyber security penetration testing.
