The BLK_BOX website is owned by HMGCC. Data that we collect from it is for legitimate interest and will be used solely for the purpose of this website.

By accepting your details and allowing you access to the BLK_BOX challenge we are not verifying your identity or committing any offer of employment or engagement.

When you visit the website we collect standard internet log information and details of visitor behaviour patterns. We do this to track web traffic to our site and collect this information in a way which does not identify anyone.

Sharing your personal data

As the data controller we use third parties to provide services for us: they are known as data processors. We ensure we only use data processors who comply with the data protection legislation and they can process personal data for us only as we have instructed them to do.
