please note that response may take a while, there's only one person managing everything.
if your download requires live render, some non-backtraceable data is temporarily stored in server's RAM. it's necessary for this feature to function.
in this case info about requested content is stored for 90 seconds and then permanently removed. no one (even me) has access to this data. official cobalt codebase doesn't provide a way to read it outside of processing functions.
you can check cobalt's source code yourself and see that everything is as stated.

current version & commit
v.7.7· December 2, 2023
bugfixes and better downloads!
this update fixes various issues with supported services. no new features yet, but twitter fix is surely something good to have in the meantime!
service improvements: • broken twitter videos are now automatically fixed by cobalt. • all vimeo videos and audios should now be possible to download. • vimeo: fixed short resolution displayed in "basic" and "pretty" filename styles.
interface improvements: • streamables are now easier to save on ios.
internal improvements: • port env variable is now not strictly necessary for cobalt to run. • minor clean up.
changes since 7.6: • fix for an issue related to youtube dubs. • fixed a memory leak related to live renders. • handling all errors related to twitter downloads. • fixed support for reddit links in various languages. • added rich filenames support for twitch clips. • updated support and donation lists.
stay tuned for future updates and have a great day :D
cobalt doesn't shove ads in your face and doesn't sell your personal data, and thus is completely free to use for everyone. but development and maintenance of a media-heavy service used by over 350k people is quite costly. both in terms of time and money. as a student, it's rather difficult for me to handle such expenses on my own.
if cobalt has helped you in the past and you want to keep it growing and evolving, you can do so by making a donation!
by donating you're helping everyone who uses cobalt: teachers, students, musicians, content creators, artists, lecturers, and many, many more!
in past few months donations have let me: • increase stability and uptime to nearly 100%. • speed up ALL downloads, especially heavier ones. • open cobalt api for free public use. • withstand several huge user influxes with 0 downtime. • move to a reliable and trustworthy cloud infrastructure provider. • separate frontend and api for resilience and future decentralization.
every cent matters and is extremely appreciated, you can truly make a difference!
