Cookie Policy — Lambda

Last updated: May 2026

This Cookie Policy explains how Vanaheim SRL (“Lambda,” “we,” “us,” or “our”) uses cookies and similar technologies when you visit our corporate website at vanaheim.io or our product website at onlambda.com. This policy should be read alongside our Privacy Policy.

We comply with the EU ePrivacy Directive (2002/58/EC as amended by 2009/136/EC) and the General Data Protection Regulation (GDPR) regarding the use of cookies and similar tracking technologies.

1. What Are Cookies?

Cookies are small text files placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and supply information to website operators.

Similar technologies include web beacons, pixels, and local storage, which function in comparable ways.

2. Essential Cookies

These cookies are strictly necessary for the website to function and cannot be switched off. They are usually set in response to actions you take, such as setting your privacy preferences, logging in, or filling out forms.

Session cookies — Maintain your session state while you navigate the website. Expire when you close your browser.
Authentication cookies — Keep you logged in to the Lambda dashboard. Expire after your session or a set period of inactivity.
Cookie consent cookie — Stores your cookie preferences so we don’t ask you again. Expires after 12 months.

Legal basis: These cookies are exempt from consent requirements under the ePrivacy Directive, as they are strictly necessary for the service you have requested.

3. Cloudflare Security Cookies

Our website is protected by Cloudflare, which may set cookies for security and performance purposes:

__cf_bm — Bot management cookie used to identify and distinguish between humans and bots. Expires after 30 minutes of inactivity.
cf_clearance — Set when a visitor completes a Cloudflare security challenge. Used to ensure the visitor is not asked to complete the challenge again for a set period. Expires after a configured duration (typically up to 24 hours).

Legal basis: These cookies are classified as strictly necessary because they are essential for website security and preventing abuse.

4. Cloudflare Turnstile Captcha Cookies

We use Cloudflare Turnstile on certain forms (e.g., the demo request form) to verify that submissions come from real users rather than automated bots:

cf_turnstile_* — Cookies set during the Turnstile challenge process to validate the user and prevent repeated challenges. These are temporary and typically expire within the session or shortly after.

Legal basis: These cookies are strictly necessary for the security and integrity of form submissions on the website.

5. Analytics Cookies (Consent Required)

We may use analytics cookies to understand how visitors interact with our website. These cookies help us measure traffic, identify popular pages, and improve the user experience. Analytics cookies are only set after you provide your consent.

Purpose: Measure website traffic, track page views, identify referral sources, and understand user behavior patterns.
Data collected: Anonymized IP addresses, browser type, pages visited, time on page, and referral URL.
Retention: Analytics data is retained for up to 26 months in anonymized form.

We do not use analytics data for advertising, profiling, or cross-site tracking. You can withdraw your consent for analytics cookies at any time by updating your cookie preferences.

Legal basis: Consent (Art. 6(1)(a) GDPR / ePrivacy Directive Art. 5(3)).

6. Cookies We Do Not Use

To be transparent, Lambda does not use:

Advertising or marketing cookies
Third-party tracking cookies
Social media tracking pixels
Cross-site retargeting cookies

7. Managing Your Cookie Preferences

You have the right to decide whether to accept or reject non-essential cookies. You can manage your preferences in several ways:

Cookie consent banner: When you first visit our website, you can accept or decline optional cookies through the consent banner.
Browser settings: Most browsers allow you to view, manage, and delete cookies through their settings. Note that blocking all cookies may impact website functionality.
