Privacy Policy
Last Updated: October 30, 2025
We are STRATUM XI, the data controller for this website. We respect your privacy and follow GDPR rules. This policy tells you how we handle your info. We only collect what's needed.
If you have additional questions or require more information about our Privacy Policy, do not hesitate to contact us.
What Info We Collect
- Contact Form: Your name and email. You give this to us.
- Analytics: We use Vercel's tool to see site visits. It's anonymized—no names or emails tied to it.
- Browser Storage: We save a small note in your browser to adjust your UI preferences. It's just for your view and not shared.
- YouTube Videos: We embed videos from YouTube. If you play one, YouTube (Google) may collect your IP address, device info, and what you watch. This happens via cookies they set.
We don't use our own cookies or track you on other sites. No other data is collected.
Why We Collect It (Legal Basis)
- Contact Form: To reply to you (our legitimate interest under GDPR Article 6(1)(f)).
- Analytics: To improve the site (our legitimate interest, anonymized so no personal data).
- Browser Storage: To make the site better for you (your consent by using it, under GDPR Article 6(1)(a)).
- YouTube: To show videos (our legitimate interest). Cookies need your consent (under GDPR Article 6(1)(a))—you give it by clicking play after a notice.
You can withdraw consent anytime by not playing videos or clearing your browser data.
How We Use It
- Reply to messages.
- Check site use to fix issues.
- Smooth your visit.
- Let you watch videos (we don't use the data from YouTube).
We don't sell or rent your info.
Who We Share With
We don't share your personal info. Analytics goes to Vercel (anonymized). For YouTube, when you play a video, data goes to Google LLC in the US. They follow the EU-US Data Privacy Framework for safe transfers. See Google's privacy policy: https://policies.google.com/privacy.
How Long We Keep It
- Contact info: Until we reply, plus 1 year max, then delete (unless law says keep longer).
- Analytics: As Vercel keeps anonymized data.
- Browser storage: Gone when you clear it.
- YouTube data: Google keeps it as they say in their policy.
We delete or anonymize when not needed.
