In summary C3 respects your privacy and is committed to handling personal information fairly, lawfully and transparently. This notice also explains our use of Lead Forensics for business website visitor identification.

1. Who we are

C3 is the trading name of Computer & Communications Co. Limited, company registration number 2488641.

Stirling House
Denney End Road
Waterbeach, Cambridge

If you have any questions about this Privacy Notice or how we use personal information, contact us at Privacy@c3.co.uk.

2. Information we collect

Information you provide to us

We may collect personal information that you provide when you contact C3, request information, enquire about our products or services, place an order, become a customer, provide feedback or otherwise communicate with us.

This may include:

  • Your name.
  • Your business email address.
  • Your telephone number.
  • Your organisation and job role.
  • Information you include in correspondence with us.

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 standard server log information where necessary to operate, maintain and protect our website, investigate technical problems and help prevent misuse or security incidents.

Lead Forensics

With your consent, we use Lead Forensics, a B2B website visitor identification service. When enabled, Lead Forensics may process an IP address and technical and website-usage information associated with a visit, including pages viewed, visit date and time, referrer, browser and device information and screen information.

Lead Forensics attempts to match the IP address to a business in its proprietary business database. Where a business match is made, C3 may receive information about the organisation and its activity on our website. The core service is intended to identify the visiting organisation rather than the named individual who visited the site.

Lead Forensics may also provide or use business-level firmographic information associated with a matched organisation. We do not use Lead Forensics to identify private household visitors for targeted advertising.

3. How we use your information

We may use personal information to:

  • Respond to enquiries and requests.
  • Provide information about C3 products and services.
  • Communicate with customers and prospective customers.
  • Process orders and manage customer accounts and relationships.
  • Provide customer support and manage existing customer relationships.
  • Send information about C3 products and services where we are permitted to do so and where any required marketing preference has been respected.
  • Operate, maintain and improve our website and services.
  • Understand business interest in C3 by identifying organisations that visit our website and the pages or solutions they appear to engage with, where you have consented to Lead Forensics tracking.
  • Meet our legal and regulatory obligations.

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.

For Lead Forensics and other non-essential website tracking technologies, we rely on your consent before activating the relevant technology. Where the information processed through that tracking constitutes personal data, consent is also the lawful basis we rely on for the related processing.

Where we rely on consent, you can withdraw that consent at any time. Withdrawal does not affect the lawfulness of processing carried out before consent was withdrawn.

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 use Lead Forensics to provide our business website visitor identification service. Lead Forensics processes information on our behalf under the applicable contractual and data-processing arrangements. The service receives technical and website-usage information when it is enabled and attempts to match a visit to a business.

Lead Forensics may use approved sub-processors to support its service. Where restricted international transfers of personal data occur, they are handled using appropriate safeguards required by applicable data protection law.

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.

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

Information processed through Lead Forensics is retained in accordance with our business needs and the applicable agreement and data-processing arrangements with Lead Forensics. Retention can vary by data type and service configuration. We review our use of the service and do not keep information for longer than is reasonably necessary for the purpose for which it was collected.

7. Cookies, tracking and website analytics

The C3 website uses Lead Forensics for business website visitor identification. Lead Forensics is non-essential to the operation of the website, so we ask for consent before activating it.

Lead Forensics states that its core service can operate without its optional cookie, but its tracking code and related technologies may process technical and website-usage information. Lead Forensics also offers an optional first-party cookie called Ifuuid. If C3 enables this cookie, it will only be used after the required consent has been obtained.

You can read more about the technologies in use, their purposes and how to change your choice in our Cookies and Tracking Technologies 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.

You can change or withdraw your website tracking choice at any time using the website's cookie or privacy settings control. You can also contact us at Privacy@c3.co.uk about a privacy request relating to C3's use of Lead Forensics.

To exercise your rights more generally, 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.

10. Changes to this Privacy Notice

We may update this Privacy Notice from time to time to reflect changes to our services, website technologies, business practices or legal requirements.

The date at the top of this page shows when this notice was most recently updated.
