The short version: nothing you type here is stored or transmitted.
URLs and options
The URL you paste and the options you choose stay in your browser. They appear in the address bar so the page can be shared or bookmarked, and they are sent to the server only if you submit the form with JavaScript disabled — in which case they are used to render the page and are not written to any log we keep or any database, because there is no database.
Accounts
There are none. Nothing to register, nothing to log in to, no email address collected.
Analytics
If analytics are enabled on this deployment, they run with consent denied by default: no analytics or advertising storage is used until you agree. Declining changes nothing about how the site works.
Cookies
The site sets no cookies of its own. Options such as --cookies-from-browser refer to your own browser's cookies being read by yt-dlp on your machine, after you run the command. They are never read by this site.
Hosting logs
The web host keeps standard access logs (IP address, timestamp, requested path) as part of running any website. We do not analyse them.
