Last updated: 18 April 2026

This policy explains which cookies Vallumio sets on this website and why. It applies to vallumio.com. The customer portal at portal.vallumio.com has its own cookie policy surfaced at signup.

1. What cookies are

Cookies are small text files that websites store on your device. They are used for things like keeping you logged in, remembering your preferences, or measuring how a site is used.

2. Which cookies we set

On this website we only set strictly necessary cookies. We do not set analytics, advertising, or third-party tracking cookies.

Strictly necessary — session

• session — Flask session cookie, used to carry the CSRF token and any error-state from form submissions. Expires when you close the browser. Required for the contact form to work.
• csrf_token — protects form submissions against cross-site request forgery. Expires with the session.

3. What we don't set

We deliberately do not set analytics cookies (Google Analytics, Plausible, Fathom, etc.), advertising cookies, or third-party tracking cookies on this marketing website. Because we use only strictly necessary cookies, no cookie consent banner is required under UK law.

If we add analytics in future, we will update this page and introduce a consent banner at that time.

4. Controlling cookies

You can disable or delete cookies in your browser settings. If you disable strictly necessary cookies the contact form on this site will not work.
