Last updated: 14 July 2026. This explains what personal data we collect, why, and what rights you have — whether you're a registered user of this service, or a director whose details appear on it because they're on the public Companies House register.
This service is operated by Whittaker IT Limited, company number 15872445 ("we", "us"), the data controller for the personal data described below. Our ICO registration reference is C1983540. For any privacy question or request, contact support@complector.co.uk or use our Contact Us page.
Account data (if you sign up): your email, a securely hashed password (or a basic profile from Google/Microsoft if you sign in that way), your company name, and your search settings. If you enable two-factor authentication, we store an encrypted authentication key and backup codes. Once paid plans launch, starting a subscription will require a payment card, handled directly by Stripe — we never receive your full card number, only limited billing details.
Public register data: company names, addresses, incorporation dates, SIC codes, and officer/director details, pulled directly from Companies House's public register. If you're a director appearing in our system, we didn't collect this from you, it comes from the public record Companies House itself publishes.
For account data: performance of our contract with you, and our legitimate interest in improving and securing the service. For public register data: legitimate interests (Article 6(1)(f) UK GDPR) in enabling business-to-business outreach using information that is already, by law, on the public record.
UK GDPR requires us to tell individuals when we obtain their data from a source other than themselves (Article 14), unless doing so individually would involve disproportionate effort, which applies here given the volume of public register entries we process. We meet this requirement through this notice. If you'd like your details removed from our system, contact support@complector.co.uk with your name and company number — we can't remove you from the Companies House register itself, only from our own copy of it.
Companies House (source of the data) · postcodes.io (postcode-to-coordinates lookup) · our hosting provider · our email provider · once paid plans launch, Stripe for payments · Google or Microsoft, only if you choose to sign in that way. We don't sell personal data or share it with advertisers.
Account data is kept while your account is active and deleted a reasonable time after closure. Public register data is refreshed periodically to reflect the current record. Billing records, once applicable, are kept for 6 years after account closure as required by UK tax law.
Under UK GDPR you can access, correct, delete, restrict, or object to our processing of your data, and receive a copy in a portable format. Manage your own account data directly from the Account page, or contact support@complector.co.uk to exercise these rights. You can complain to the Information Commissioner's Office if unsatisfied with our response.
Three strictly-necessary cookies, none used for tracking or advertising: a session cookie (keeps you logged in), a short-lived one during Google/Microsoft sign-in, and an optional "remember this device" cookie if you skip two-factor authentication on a trusted device. No tracking cookies means no cookie banner is required under PECR.
This service is intended for business use by adults; we don't knowingly collect data from anyone under 18. We'll update the date at the top of this page whenever this policy changes.
