Information collected when you use our website

When you visit our website, our web server may automatically record limited technical information as part of its standard operation. This may include your IP address, the date and time of your visit, the pages or files requested, your browser or device type, the referring page and information about whether the request was successfully completed.

We use this information only where necessary to operate, maintain and protect our website, investigate technical problems and help prevent misuse or security incidents. We do not use server log information for advertising, profiling or behavioural tracking.

We do not currently use website analytics services or advertising technologies to monitor visitors to the website, and the website code does not intentionally set analytics or marketing cookies.

We may use personal information to:

4. Our lawful basis for processing

Data protection law requires us to have a lawful basis for using personal information. Depending on the circumstances, our processing may be necessary to perform a contract or take steps at your request before entering into a contract, to comply with a legal obligation, for our legitimate business interests, or because you have given consent.

Our legitimate interests include responding to enquiries, managing customer and business relationships, operating and protecting our systems and website, and maintaining the security and availability of our services.

Where we rely on consent, for example for certain marketing communications, you can withdraw that consent at any time.

Where standard server log information contains personal data, we process it on the basis of our legitimate interests in maintaining the security, availability and effective operation of our website.

5. Who we share information with

We do not sell personal information and we do not share personal information with other companies for their own marketing purposes.

We may share personal information with trusted service providers and suppliers where necessary to operate our business, provide our services or support our systems. Where relevant to processing an order, information may also be shared with credit reference or fraud prevention agencies.

We may also disclose information where required by law, to regulators or law enforcement bodies, or where necessary to establish, exercise or defend legal rights.

6. How long we keep your information

We keep personal information only for as long as it is reasonably necessary for the purpose for which it was collected, including satisfying legal, regulatory, accounting or reporting requirements.

Personal information is reviewed and, where it is no longer required, deleted or securely disposed of in line with our data protection procedures.

Server log information is retained only for as long as reasonably necessary for website operation, security and troubleshooting, in accordance with our hosting arrangements.

7. Cookies and website analytics

The C3 website does not currently use analytics services, advertising technologies or marketing cookies to monitor visitors. The website code does not intentionally set cookies for analytics, advertising, profiling or behavioural tracking.

You can read more about the current website setup in our Cookies notice.

8. Your data protection rights

Depending on the circumstances, data protection law gives you rights relating to your personal information.

These may include rights to request access to the information we hold about you, ask us to correct inaccurate information, request deletion or restriction of your information, and object to certain processing. Where processing is based on consent, you may also withdraw that consent.

To exercise your rights, contact Privacy@c3.co.uk. We may need to verify your identity before providing personal information or acting on a request. We aim to respond to subject access requests within 30 days.

9. How we protect your information

We use appropriate organisational and technical measures designed to protect personal information against unauthorised access, alteration, disclosure or loss.

These measures include restricting access to people who need personal information for their work, using approved systems and secure storage, applying access controls and password protection, maintaining backups, and using appropriate security software and firewall protection.

Staff are expected to handle personal information in accordance with C3's data protection procedures and to avoid unnecessary copying or disclosure of personal data.
