Controller

I, Long Bui, am responsible for this website. You find my postal address in the Impressum, and you can reach me at hello@long-bui.de.

Hosting and server logs

This website runs on servers I own and operate myself; no hosting provider is involved. Fonts and the other files of the site come from there too, apart from the TMDB posters described below. When you open a page, the server processes technically necessary data: IP address, date and time, requested address, HTTP status code, browser identifier (user agent) and referrer. This is needed to deliver the site and fend off attacks. The legal basis is Art. 6(1)(f) GDPR. This data only ends up in the container logs, which Kubernetes rotates by size with its default settings and deletes when the container is replaced; there is no separate log archive, and the logs are not analysed or combined with other data.

Cloudflare

Requests to long-bui.de pass through the network of Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA, before they reach my server. Cloudflare processes the connection data listed above to deliver the site and protect it from attacks. The legal basis is Art. 6(1)(f) GDPR; my legitimate interest is secure and reliable operation. Cloudflare is certified under the EU-US Data Privacy Framework; transfers to the USA rely on the European Commission's adequacy decision (Art. 45 GDPR). I have a data processing agreement with Cloudflare. More: https://www.cloudflare.com/privacypolicy/

Anonymous usage statistics

I use a self-hosted, privacy-friendly analytics platform (Umami) to collect anonymous usage statistics. It sets no cookies, stores no IP addresses and collects no personal data, which is why this site has no consent banner. It counts page views and two events: downloads of my CV as PDF and clicks on my mail address. I use the numbers only to see what gets read. No data is shared with third parties or used for advertising. The legal basis is Art. 6(1)(f) GDPR.

TMDB on the projects page

On the projects page, the preview of cine-whisper shows film posters. Your browser loads them directly from image.tmdb.org, a server of The Movie Database (TMDB), so TMDB receives your IP address and your browser identifier (user agent). I have no influence on how TMDB processes this data. The legal basis is Art. 6(1)(f) GDPR; my legitimate interest is showing the product as it really looks. Other pages make no requests to TMDB.

Cookies and local storage

On your first visit, the site sets the cookie PARAGLIDE_LOCALE, which stores your language and expires after 400 days. Light or dark mode follows your system and is kept in your browser's local storage under the key mode-watcher-mode. Both are strictly necessary for the function you use (§ 25(2) no. 2 TDDDG). There are no other cookies.

Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18) and data portability (Art. 20), as well as the right to object to processing based on Art. 6(1)(f) GDPR (Art. 21). There is no automated decision-making or profiling. An email to hello@long-bui.de is enough.

You also have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR). The authority responsible for me is: Der Hessische Beauftragte für Datenschutz und Informationsfreiheit, Postfach 3163, 65021 Wiesbaden, Germany, https://datenschutz.hessen.de
