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 20 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.

v.7.6· October 15, 2023
customizable file names, instagram stories, and first cobalt sponsor!
as many have (very) often requested, cobalt now lets you pick between several file name format styles! go to settings > other and change it to whichever you like! there's a preview of each style, so you know how exactly files are gonna look like.
if you liked file names the way they were before, don't worry: classic style is still the default :)
on a different but not any less important note: cobalt is now sponsored by royalehosting.net! overall service performance and stability is gonna be better, but also more content will be possible to download thanks to geniuine server locations. and yes, still no ads or trackers.
this update also includes a bunch of other changes, check them out:
service improvements: • added support for instagram stories thanks to #194. • fixed reddit support thanks to #221. • added support for rich file names for youtube, vimeo, soundcloud, rutube, and vk. • numbers and emoji no longer disappear from file name and metadata. • mute and audio dub file name tags don't appear together anymore. • youtube: dub file name tag doesn't appear anymore if audio track is default.
interface improvements: • added a list of sponsors to about tab. if you host an instance, it's disabled by default, but can be enabled with showSponsors env variable. • about button now opens about tab when no new changelog is available. • fixed download button thickness on ios.
you now can reach out to cobalt via email for support! it's located in the about tab along with other socials, such as discord.
i hope you enjoy this long-awaited update and have a blissful day :D
- fixed support for reddit links in various languages (#253). - added rich filenames support for twitch clips (#233).
help it stay online
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!
