privacy policy

Who is responsible
Responsible for the processing of personal data on this website (controller, Art. 4 (7) GDPR) is Lennart[remove-this] Novak, Biber[remove-this]weg 9, 47562 [remove-this]Weeze, Germ[remove-this]any, contact@le[remove-this]nnzone.com.
In short
This site sets no cookies, uses no analytics or tracking and loads nothing from other servers: fonts, scripts and images all come from lennzone.com. Personal data is only processed where delivering the site needs it, and when you write me an e-mail.
Hosting: Cloudflare
The site is a set of static files hosted on Cloudflare Pages, a service of Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA, which also manages the domain lennzone.com. To deliver a page, Cloudflare necessarily receives your IP address and may log it together with the date and time, the requested page, the referring page and information about your browser, to deliver the site and to protect it against attacks and abuse.
Legal basis is Art. 6 (1) (f) GDPR: my legitimate interest in presenting the site reliably and securely. Cloudflare processes data in the USA. Cloudflare is certified under the EU-US Data Privacy Framework, on which the transfer is based (Art. 45 GDPR). More in Cloudflare's privacy policy: https://www.cloudflare.com/privacypolicy/
When you write to contact@le[remove-this]nnzone.com, Cloudflare (see above) receives the mail and forwards it to my personal mailbox at Google (Gmail, Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland). I use your address and your message only to answer you, and delete them when the conversation is over, unless the law asks me to keep them.
Legal basis is Art. 6 (1) (b) GDPR when you write about a job or a project (steps before a contract), otherwise Art. 6 (1) (f) GDPR: my legitimate interest in answering messages.
Storage in your browser
The terminal on the start page remembers your session in your browser's local storage, so that it looks the same when you come back: "lnos.history" holds the commands you entered, "lnos.screen" the last 200 commands with their output and the current folder, "lnos.lastLogin" the date and time of your last visit (shown as "Last login"), "lnos.files" the files and folders you create in the terminal yourself, with their content. If you play snake, "lnos.snake" keeps your best score. When you go from the website back to the terminal, "lnos.backFromSite" is kept in the session storage of this tab. It is gone when you close the tab. When you switch the screen effects off or on with "crt", "lnos.crt" keeps that choice in the local storage.
These entries stay on your device and are never sent to me or anyone else. They are strictly necessary for the terminal and the screen you use (§ 25 (2) no. 2 TDDDG), so no consent is asked for.
The command "neofetch" shows the name of your browser, which it reads from the browser itself. It only appears on your screen. It is not stored and not sent anywhere.
You can delete them at any time: "history -c" deletes the command history, "clear" empties the stored screen, "rm" deletes files you created, and the settings of your browser delete all data of this site, the time of the last visit included.
Links to other sites
Links to other sites (GitHub, LinkedIn, projects) are plain links: nothing is loaded from those sites until you click one. From then on, the privacy policy of that site applies.
The file "RUN_ME.sh" in the terminal opens a video on YouTube in a new tab when you run it. Until then nothing is loaded from YouTube. From then on, the privacy policy of YouTube (Google) applies.
Your rights
You have the right to access your data (Art. 15 GDPR), to have it corrected (Art. 16), deleted (Art. 17) or its processing restricted (Art. 18), to receive it in a portable form (Art. 20) and to object to processing based on Art. 6 (1) (f) GDPR (Art. 21). Write to contact@le[remove-this]nnzone.com.
You also have the right to lodge a complaint with a supervisory authority (Art. 77 GDPR), for example the one responsible for me: Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen, Kavalleriestraße 2-4, 40213 Düsseldorf, Germany, https://www.ldi.nrw.de
