Privacy Policy

Effective Date: October 4, 2026

Thank you for your interest in our website. Your privacy is important to us. This Privacy Policy explains how we collect, use, and protect your personal information in accordance with the applicable data protection regulations (including GDPR and national laws).

1. Data We Collect

We collect the following personal data that you voluntarily provide:

  • Name and email address: when submitted via the contact form.
  • Email address: when you sign up for the newsletter.

Additionally, if you allow them in the cookie settings, we use Google Analytics and PostHog to collect usage statistics. This includes data such as:

  • Browser type and version
  • Operating system
  • Referrer URL
  • IP address (anonymized)
  • Time and duration of visits
  • Visited pages and user interactions
  • Approximate location (city, country)
  • Clicks, scrolling and mouse movement (heatmaps)
  • Session recordings of your visit (text typed into form fields is masked)

We use cookies to improve your user experience and gather statistical data. Analytics cookies are only set after you allow them in the cookie banner, where Google Analytics and PostHog (heatmaps and session recordings) can be switched on or off separately. You can change your choice at any time via “Cookie settings” in the footer, or disable cookies in your browser settings, although this may limit functionality.

2. Purpose of Data Collection

We process your personal data for the following purposes:

  • To respond to your inquiries submitted via the contact form.
  • To send newsletters or updates if you have subscribed.
  • To improve our website and services using anonymized analytics data.

Your name and email address are only used for the purpose for which they were provided. If you subscribed to our newsletter, you can unsubscribe at any time by sending a request to contact@nexclass.lu.

3. Legal Basis

The legal basis for processing your data is your consent (Article 6(1)(a) GDPR), which you give when you submit the contact form or subscribe to our newsletter.

You can revoke your consent at any time by contacting us at contact@nexclass.lu. The withdrawal of consent does not affect the lawfulness of processing based on consent before its withdrawal.

Analytics cookies and similar technologies (Google Analytics, PostHog) are only used with your consent (Article 6(1)(a) GDPR), which you give or refuse in the cookie banner. You can change or withdraw your choice at any time via “Cookie settings” in the website footer.

4. Data Sharing

We do not sell, rent, or disclose your personal data to unauthorized third parties.

We may use trusted third-party service providers for hosting, email delivery, or analytics (e.g., Google Analytics, PostHog). These providers are bound by data processing agreements and process your data only on our instructions and in accordance with the GDPR.

5. Data Retention

We retain your data:

  • As long as necessary to respond to your inquiries,
  • Until you unsubscribe from our newsletter,
  • Or until you request its deletion.

Google Analytics data is retained according to Google's policies, generally for up to 14 months, and is anonymized. PostHog session recordings are retained for 30 days; other PostHog analytics data is kept only as long as needed for statistical evaluation, and we delete it on request.

6. Your Rights

Under the GDPR, you have the right to:

  • Access your personal data
  • Correct or update inaccurate data
  • Request the deletion of your data ("right to be forgotten")
  • Withdraw your consent at any time
  • Object to certain types of processing
  • File a complaint with your local data protection authority

To exercise any of these rights, please contact us at contact@nexclass.lu.

7. Use of Google Analytics

Our website uses Google Analytics, a service provided by Google Inc., which uses cookies to analyze your use of our site. The information generated by the cookies is transferred to and stored on servers in the USA. Your IP address is anonymized before storage and processing.

You can prevent Google Analytics from collecting your data by installing the browser add-on available at: https://tools.google.com/dlpage/gaoptout?hl=en

More information about how Google handles your data is available at: https://www.google.com/intl/en/policies/privacy/

8. Use of PostHog

If you allow it in the cookie settings, our website also uses PostHog, an analytics service provided by PostHog Inc. We use PostHog's EU cloud, so the data is processed on servers in the European Union. PostHog collects page views, clicks, scroll and mouse activity (heatmaps), performance metrics, error reports and session recordings of your visit. Your IP address is anonymized, and text typed into form fields is masked in recordings.

PostHog stores a random identifier in cookies or local storage in your browser. If you decline or withdraw your consent, PostHog is not loaded, collects no data, and identifiers it set earlier are removed from your browser.
