How your personal data is collected

We collect most of this personal data directly from you—in person, by telephone, text or email and/or via our website. However, we may also collect information from a third party, e.g.:

  • your employer
  • from cookies on our website—for more information on our use of cookies, please see the Cookies Settings button on our website
  • through the Scenario Builder platform, using Userpilot's software (including cookies) to capture and analyse how you use it
  • via our IT systems, e.g.:
    • from door entry systems and reception logs
    • through automated monitoring of our websites and other technical systems, such as our computer networks and connections, CCTV and access control systems, communications systems, email and instant messaging systems

How and why we use your personal data

Under data protection law, we can only use your personal data if we have a proper reason, e.g.:

  • where you have given consent
  • to comply with our legal and regulatory obligations
  • for the performance of a contract with you or to take steps at your request before entering into a contract
  • for our legitimate interests or those of a third party.

A legitimate interest is when we have an operational or commercial reason to use your information, so long as this is not overridden by your own rights and interests. We will carry out an assessment when relying on legitimate interests, to balance our interests against your own.

The table below explains what we use your personal data for and why:

AMP (AI chatbot)

When you interact with the chatbot on our platform, Scenario Builder, we will process your chats and interactions with the bot, and associate them with your user identity, to:

  • operate the chatbot and enable it to process your input and respond to it, so that we can provide the chatbot to you; and
  • understand how you use the chatbot and any problems you encounter with it, so that we can improve the bot and our service more generally.

We do that on the basis of our legitimate interest in providing the bot and understanding how it is used.

We use Google Gemini to power the bot, so your inputs will be shared with and processed by Google in order to formulate responses. Your personal data will therefore be transmitted to Google in the United States of America. We have configured Google Gemini not to retain your inputs or the responses generated. You can find out more about how Google protects
your personal data here.

We also use Langfuse to help us to analyse your chats and interactions with the bot, so that information will be shared with them. They will store your information within the European Union, and will only use that information to provide their service to us.

We will retain this information for 180 days, after which time we will aggregate and anonymise it, and then delete the original versions.

Session replay and product analytics (Userpilot)

When you use our platform, Scenario Builder, we use Userpilot to understand how you interact with it.

What we collect through Userpilot:

  • the pages you view and the features you use;
  • your clicks, mouse movements and scrolling;
  • text you type into ordinary, non-sensitive fields; and
  • basic technical information about your browser, device and session.

What we do not collect:

  • we do not make a video or audio recording of your screen;
  • sensitive information you enter, such as passwords, is masked in your browser before anything is sent, so Userpilot never receives or stores it; and
  • we mask or exclude the parts of Scenario Builder that display your modelling work, so the scenarios, data and files you create or upload are never sent to Userpilot.

We use this information to diagnose and fix problems, and to understand how the platform is used so that we can improve it.

Userpilot, Inc. is our data processor and stores this information in the United States, so your personal data will be transferred there. You can find out more in Userpilot's privacy policy. Userpilot keeps session replays for 30 days, and related product-analytics data for up to 3 years, after which it is deleted.
