Privacy policy
How LSTE collects and uses personal data. Last updated: October 2026.
1. Who we are
The LSTE website (lste.lu) is operated by Q-Leap SA, a company incorporated under Luxembourg law, registered at:
Q-Leap SA
10B rue des mérovingiens
L-8070 Bertrange
Luxembourg
Q-Leap SA acts as the data controller for all personal data collected through this website. Questions about how we handle personal data can be sent to hello@lste.lu.
2. Data we collect
We collect only the data necessary to operate this website and communicate with our community.
Contact form
When you submit our contact form, we collect your name, email address, and message.
Newsletter
If you subscribe, we collect your email address only. Subscription is optional and requires your consent; you may unsubscribe at any time via the link in any email.
Website analytics (only with your consent)
If you accept analytics cookies, we use Google Analytics 4 to understand how the website is used: pages viewed, how you arrived (search engine, link, newsletter), approximate location (country and city), device, browser and screen type, and interactions such as scrolling, outbound link clicks and file downloads. Google Analytics 4 does not log or store IP addresses, and we do not use it for advertising. If you decline, Google Analytics is not loaded and nothing is measured.
3. How we use your data
- To respond to enquiries: we use your name and email to reply to messages sent via the contact form.
- To send the LSTE newsletter: if you've subscribed, to share event and speaker updates. You may unsubscribe at any time.
- To improve the website: if you've accepted analytics cookies, to see which pages are visited and how people find the event, in aggregated statistics.
We do not use your personal data for automated decision-making or profiling.
4. Legal basis for processing
- Consent (GDPR Art. 6(1)(a)): for newsletter subscriptions and for analytics cookies (Google Analytics). You can withdraw your consent at any time.
- Legitimate interests (GDPR Art. 6(1)(f)): for responding to contact form enquiries from people who have actively reached out to us.
5. Data retention
- Contact form data: retained for up to 2 years from submission, unless an ongoing relationship requires longer.
- Newsletter subscriptions: retained until you unsubscribe; removed within 30 days after.
- Analytics data: Google Analytics keeps visit-level data for 2 months, after which only aggregated reports remain. The analytics cookies themselves expire after up to 2 years.
6. Third parties & data transfers
The Contact page and newsletter signup both use a plain "Email hello@lste.lu" button that opens your own email client — we don't process either through any third-party form service.
If you accept analytics cookies, usage data is processed by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland) as our processor for Google Analytics. Google may transfer this data to Google LLC in the United States, which is certified under the EU–US Data Privacy Framework. Google's own practices are described at policies.google.com/privacy.
We do not sell, rent, or trade your personal data. We do not use it for advertising beyond LSTE communications you've consented to.
7. Your rights
Under the GDPR, you have the right to access, rectify, erase, or port your personal data, to object to processing based on legitimate interests, and to withdraw consent at any time. To exercise any of these rights, contact hello@lste.lu; we respond within 30 days, free of charge.
