Privacy & Cookies Policy

Last Updated: April 2026

Welcome to The CtC Ratio. This Privacy & Cookies Policy explains how we collect, use, and protect your information when you visit our website (ctcratio.co.uk).

1. Information We Collect

We built this tool to be as anonymous as possible. We do not require you to create an account to use the map. The data we collect falls into two categories:

Automatically Collected Data: When you use the site, our analytics provider (PostHog) automatically collects basic usage data. This includes your IP address, browser type, device type, and how you interact with the map (e.g., which postcodes you search).

Voluntarily Provided Data: If you choose to contact us via email for commercial inquiries, we will retain your email address and any information you provide strictly for the purpose of responding to your inquiry.

2. How We Use Your Information

We use the information we collect to:

  • Ensure the interactive map functions correctly on your device.
  • Understand aggregate user behavior to improve our property methodology and UI.
  • Monitor against spam, bots, or abuse of the platform.

3. Cookies & Tracking Technologies

In accordance with the UK Privacy and Electronic Communications Regulations (PECR), we use cookies and similar tracking technologies to operate the site:

Essential Cookies: Necessary for the site to load and function securely.

Analytics Cookies: We use PostHog to understand how users interact with our data. PostHog uses cookies to distinguish unique users and track session engagement.

Affiliate Tracking:If you click on an external sponsored link or affiliate partner (e.g., mortgage calculators or estate agents), that third party may place a cookie on your browser to track the referral source. We do not control these third-party cookies, and they are governed by the respective partner's privacy policy.

4. Data Sharing & Third Parties

We do not sell your personal data. We only share data with service providers strictly necessary to run the site (e.g., our hosting provider Vercel, and our analytics provider PostHog).

5. Your UK GDPR Rights

If you are located in the UK or the EEA, you have the right to access, correct, delete, or restrict the processing of any personal data we may hold about you. To exercise these rights, please contact us.
