The short version
This site is a static personal portfolio. It has no accounts, no login, no forms, no database and no backend of its own. Nothing you type into the terminal is transmitted anywhere — it is processed in your browser and forgotten when you close the tab.
Controller (Verantwortlicher)
Melvin Rinkleff c/o Langdock GmbH Greifswalder Str. 212 10405 Berlin Germany quintet-79turnips@icloud.com
This is a personal site. It is not operated by Langdock GmbH, and nothing on it is a statement by or on behalf of Langdock GmbH.
Hosting
The site is hosted by Vercel Inc. When you request a page, Vercel processes the data any web server necessarily receives: your IP address, the page requested, the time, your user agent and referrer. This is done to deliver the site and keep it secure, on the basis of a legitimate interest in operating a working website (Art. 6(1)(f) GDPR).
Vercel is a US provider. Transfers are covered by the EU standard contractual clauses and the EU–US Data Privacy Framework.
Analytics
The site uses Vercel Web Analytics and Vercel Speed Insights to count page views and measure loading performance.
Both are cookieless. They set no identifiers on your device and do not track you across sites or sessions. Measurements are aggregated, and no profile of an individual visitor is created — which is also why no consent banner appears: there is nothing stored on your device to ask about. The legal basis is again a legitimate interest, in knowing whether the site works and whether anyone reads it (Art. 6(1)(f) GDPR).
What is stored in your browser
The site keeps a few things in your browser’s local storage so it behaves sensibly when you come back:
melvinos:settings— theme, wallpaper, font size, reduced-motion preferencemelvinos:history— your terminal command historymelvinos:mode— whether you last used the terminal or the desktopmelvinos:icon-positions— where you dragged the desktop iconsmelvinos:desktop-tip-seen— whether the first-visit hint was dismissed
None of this is a cookie, none of it is sent to a server, and none of it reaches me. It stays on your device and you can clear it at any time through your browser settings.
External links
The site links to GitHub, LinkedIn, YouTube, Instagram and Langdock, and to my own projects on subdomains of rinkleff.dev (m42.rinkleff.dev, hy310.rinkleff.dev). Following a link means that provider’s own privacy policy applies; I have no influence over what they collect.
Your rights
Under the GDPR you have the right to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing (Art. 21).
To exercise any of them, write to quintet-79turnips@icloud.com.
You also have the right to complain to a supervisory authority — in Germany, the data protection authority of the federal state in which you live.
Changes
