Cookie Policy

Last updated: 19 May 2026

1. About This Policy

This Cookie Policy explains how AI-EPC uses cookies and similar technologies (such as localStorage and sessionStorage) when you visit our website at ai-epc.co.uk or use the AI-EPC platform.

AI-EPC is operated by E8 Portal Limited trading as AI-EPC, registered in England and Wales (registered address: Prama House, 267 Banbury Road, Summertown, Oxford, OX2 7HT). For more information about how we handle personal data, please read our Privacy Policy.

2. What Cookies Are

Cookies are small text files placed on your device when you visit a website. They are used to make websites work, or work more efficiently, and to provide information to the owners of the site. Similar technologies such as local storage and session storage allow data to be stored in your browser for related purposes.

In this policy, “cookies” includes both traditional HTTP cookies and these similar browser storage technologies.

3. How We Use Cookies

3.1 Strictly necessary cookies

These are essential for the Service to function. They cannot be switched off because the Service will not work without them.

  • Session cookie — issued when you sign in. It keeps you logged in and ties subsequent requests to your authenticated session. Issued by express-session and stored server-side in our PostgreSQL session store.
  • CSRF protection — helps protect requests from cross-site request forgery.
  • Mobile authentication tokens — if you use the mobile app, a short-lived JWT may be stored on your device to keep you signed in.

3.2 Preference cookies

These remember choices you make so we can show you a more consistent experience.

  • Persona / user type — remembers whether you chose the Landlord or Assessor entry on the homepage so we can take you straight to your hub on return visits.
  • UI preferences — things like dismissed banners, preferred dashboard view, and theme.
  • EPC Emulator usage — tracks how many free lookups you’ve used as a guest, so we can offer signup at the right moment.

3.3 Analytics cookies

We may use privacy-respecting analytics to understand how the Service is used in aggregate — for example which pages are most viewed, where users drop off in funnels, and how new features perform. These cookies only run where you have consented (where consent is required by law).

We never sell analytics data and we do not use third-party advertising cookies on the Service.

3.4 Payment cookies

When you reach a checkout or billing screen, our payment processor Stripe may set its own cookies to detect fraud and secure the payment process. These are governed by Stripe’s own cookie and privacy notices.

4. Third-Party Cookies

The third parties whose cookies may be set through the Service include:

  • Stripe — payment processing, fraud prevention. See stripe.com/cookies-policy/legal.
  • Google Fonts — loads the Roboto font family used across the platform. Google Fonts can log the IP address of the browser requesting the font; no cookies are set by the font request itself.
  • Mapping & address lookup providers — used by features that require a UK address or postcode.

5. Managing Your Cookies

Most web browsers allow you to control cookies through their settings. You can usually find these under “Settings”, “Preferences” or “Privacy”. You can block or delete cookies, choose to be warned before a cookie is set, or set your browser to refuse third-party cookies altogether.

Please note that if you block strictly necessary cookies, parts of the Service may not work properly — for example you will not be able to stay signed in.

For the AI-EPC persona and UI preferences described in section 3.2, you can also clear them by signing out and clearing your browser’s site data for ai-epc.co.uk.

6. Do Not Track

Some browsers offer a “Do Not Track” (DNT) setting. There is no consistent industry standard for how DNT signals should be interpreted, so the Service does not currently respond to DNT headers. We continue to honour the consent choices you make through any cookie banner or browser settings.

7. Changes to This Policy

We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for operational, legal or regulatory reasons. The “Last updated” date at the top of this page will always reflect the most recent revision.
