Cookie Policy

Last updated June 30, 2026

1. Introduction

This Cookie Policy explains how Datalumo, a service provided by vanrossum.dev (registered in The Netherlands), uses cookies and similar technologies on our website. We are committed to transparency and to compliance with the GDPR, the Dutch Telecommunications Act, and the ePrivacy Directive.

2. What are cookies?

Cookies are small text files stored on your device (computer, tablet, or mobile phone) when you visit a website. They help a site work efficiently, improve your experience, and can provide insight into how the site is used.

3. Our approach to cookies

We take a privacy-first approach. We do not use cookies for behavioural tracking, advertising profiles, selling data to third parties, or non-anonymised analytics.

4. Cookies we use

We use three strictly necessary cookies:

  • datalumo_session (session / 2 hours) — maintains your login status.
  • XSRF-TOKEN (session / 2 hours) — prevents cross-site request forgery.
  • remember_web_* (up to 5 years) — remembers your login so you stay signed in.

These cookies are classified as strictly necessary under Dutch and EU law, which means they do not require your consent.

5. Analytics

Any analytics we use are privacy-focused: they do not use cookies, do not track individuals, do not collect personal data, and do not require consent.

6. Third-party cookies

We do not allow third-party tracking cookies on our website. Payment providers may set necessary cookies during checkout.

7. Managing cookies

You can control or delete cookies through your browser settings. Most browsers — including Chrome, Firefox, Safari, and Edge — let you block or remove cookies; note that blocking strictly necessary cookies may prevent you from logging in.

8. Changes to this policy

We may update this Cookie Policy from time to time. Any changes will appear on this page with a revised "last updated" date.
