Privacy
About this policy
zeigarn.com is the website of the Zeigarn YouTube channel, run by Kaan Demir. This policy covers this website. Questions about it: [email protected].
Votes and the idea box
There are no accounts, cookies or visitor analytics on this website. If you vote in the poll, your choice is stored with a one-way, salted hash of your IP address so each visitor can vote once per round; the IP address itself is not stored, and the hash is deleted after 90 days. If you send a thought through the idea box, the text, the time, the page language and the country reported by our hosting provider are stored so I can read it; a salted hash of your IP address is kept for one minute to limit sending. Please leave out names and personal details. You can ask for a message to be deleted by email.
Data in your browser
If you choose a language, it is saved in your browser's local storage under zeigarn-language. If you turn the sound on or off, that choice is saved there too, under zg-sound. So that the opening plays once per visit, the site keeps a flag in session storage (zg-night-seen) that disappears when you close the tab. None of this is sent to the server.
Hosting and outside services
The website is hosted on Cloudflare, which may process technical data such as your IP address, the requested page, the time and your browser information to deliver and protect the site. Fonts and images are served from this website. Film titles and thumbnails load from YouTube (Google), which may receive your IP address and technical request information. A film plays on this page only after you press Play here; the player then loads from YouTube's privacy-enhanced domain (youtube-nocookie.com) under Google's terms. Links to YouTube, the App Store, GitHub, LinkedIn and demirkaan.com are subject to those services' privacy terms.
Project demos
The game and app demos open on demirkaan.com, a separate site with its own privacy policy. Some of them keep data in your browser or load outside services such as YouTube and Mapillary.
Contact and requests
If you send an email, your address and message are processed to answer you. You can ask to access, correct or delete your data at [email protected]. Messages are kept as long as the conversation needs them and as required by law. Changes to this policy are published on this page.
