Privacy policy

Operator and scope

This policy applies to lucianlabs.dev and www.lucianlabs.dev, operated by Lucian. Send privacy questions to lucian.sw.kim@gmail.com.

Visits and email inquiries

The site has no account registration or on-site contact form. Hosting and external services may process your IP address, requested URL, access time, and browser or device information when delivering pages and files, for delivery, stability, and security.

Email links open your mail app. If you send an email, your address and message are received by the operator and processed in Gmail. They are used to respond to your inquiry and deleted when no longer needed. Please do not send passwords or financial information.

Browser storage

Korean and English pages have separate addresses (English pages start with /en/). The country that the hosting service associates with your connection IP is stored in the lucianlabs_auto_locale session cookie and is used only to decide whether to suggest the other language version; it does not change page content. The site does not request GPS or location permission. Your explicit language choice is stored in local browser storage and the lucianlabs_locale cookie for up to one year and shared across lucianlabs.dev pages and subdomains. Cookies are included in requests to the corresponding domain. Motion preferences and whether you dismissed the language suggestion remain in local storage. Clearing site data removes stored settings.

Lotto Lab draws run in your browser. Share links may include selected challenge settings in the URL, visible to the recipient. The current version clears legacy draw history if it remains in session storage.

External services

The site is hosted on Vercel. Some project pages and HTML films request fonts or libraries from Google Fonts and external CDNs. These requests may disclose your IP address and request details to the provider.
