Last updated 5 May 2026 · Knight Designs Ltd

This page sets out how Knight Designs Ltd ("Knight Designs", "we", "us", "our") collects and uses information when you visit kdtfc.com, contact us, or engage us as a consultant. We are committed to keeping the amount of personal data we hold to the minimum needed to do good work and to comply with the law.

1   Who we are & how to contact us

The data controller is Knight Designs Ltd, a limited company registered in England and Wales, based in Weybridge, Surrey.

For any privacy enquiry — to access, correct, delete or object to our use of your data, or to make a complaint — please email hello@kdtfc.com or call 01932 558406.

2   What data we collect

We only collect data we need to deliver our work or run the website. In practice that means:

SourceData
Enquiry form / email / phone Your name, email address, phone number, company, and the project details you choose to share.
Project engagement Drawings, specifications, correspondence, invoicing details and any other documents you send us in the course of a job.
Website analytics Anonymous, aggregated information about how the site is used (pages viewed, country, device class). We do not collect IP addresses, fingerprint visitors, or use third-party advertising trackers.
Interactive tools Inputs you type into our calculators (postcodes, panel build-ups, joist spans etc.) are processed in your browser only and are not transmitted to us. The Frame Builder game stores your name, optional company and score on the public leaderboard if you choose to submit them.

We do not knowingly collect data from anyone under the age of 18.

3   How and why we use your data

The lawful bases on which we process personal data are:

We do not use your data for automated decision-making or profiling, and we do not sell or rent it to anyone.

4   Who we share data with

We share personal data only with the small set of providers we need to run the business:

Each provider is bound by a written data processing agreement that requires them to handle data only on our instructions and to keep it secure. We do not transfer personal data outside the UK or EEA where practicable; where any provider stores data overseas, transfers are covered by UK-approved safeguards (e.g. the UK International Data Transfer Addendum).

8   Google Analytics 4

This website uses Google Analytics 4 (measurement ID G-CKQMZFV3G6) to understand which pages, tools, and content are useful to visitors. We do not use it for advertising, retargeting, or any commercial profiling.

Google Analytics is loaded only after you click Accept on the cookie banner shown on your first visit. If you click Decline, no analytics cookies are set and no data is sent to Google. Your decision is stored in your browser's local storage so you are not asked again.

If you accept analytics, the following information is sent to Google Analytics:

No personally identifying information is collected. Knight Designs Ltd does not have access to your raw IP address, and we do not link analytics data to individual people.

To change your decision later: clear the kd_analytics_consent item from your browser's local storage and reload the page — the banner will appear again. You can also block analytics entirely with a privacy extension such as uBlock Origin or Privacy Badger.
