Privacy Notice

This notice sets out how Criteria uses and protects personal information that we process using telluswhatyouthink.co.uk.

For details about other personal data that we process, see the privacy notice on our main corporate website: https://www.criteria.co.uk/privacy-notice

Our ICO registration number is Z755360X.

We always process personal data within the UK, unless it is necessary to transfer data outside the UK for a specific client project. Research participants will be notified if the project requires data to be transferred outside the UK and the safeguards that will be used to protect their data, before commencing.

The security of personal data is important. We use a wide range of organisational, technical, physical and operational controls to prevent unauthorised access to data, which are assessed on a regular basis.

We will not sell your data to third parties for use outside the activities that we agree with you. We will not share data with 3rd parties unless they are specifically processing that data under contract, on our behalf.

Tell Us What You Think community members

When you sign up to our Tell Us What You Think community, we use the information that you provide to identify research projects that may be suitable for you to attend with your consent.

Market research activity needs to be as representative as possible and may need to focus on individuals with certain interests, characteristics or beliefs. You will be asked questions about your background, lifestyle and products and services that you use.

Some research activities may require collection of sensitive data, such as ethnic origins, health, religion, sexual orientation or political beliefs. You are not under any obligation to provide this information and we will always obtain explicit consent at the point of data capture.

We will retain your information until you ask to be removed from the Tell Us What You Think community or request that you are not considered for future market research activity. You can ask for your profile to be deleted using the form on the My Data page, or by contacting info@criteria.co.uk. We will remove your details within one month. We will also add your email address and phone number to our Do Not Contact database to ensure that we don't contact you again.

We use well-established IT service providers to process the data. This website and its database are hosted in London. Some providers we use are based outside the UK: Cloudflare, which helps deliver and protect the website, and, only if you choose to switch on the optional cookies described below, Google and Meta. Where personal data is transferred outside the UK, we make sure that appropriate safeguards are in place.
