TorBox is not a cloud storage service. TorBox downloads your files from different places on the internet and makes them temporarily available for you to download. Well, how long is "temporarily"?
TorBox stores each file for at least 30 days.
This day count is subject to change, and this document will always have the most updated count. This can change due to multiple things such as over-usage, abuse, and more, but it'll likely stay at 30 days.
Can TorBox Store For Longer?
In most cases yes. If a file is popular enough it will stay cached for longer. There is no real limit to how long files can stay cached as long as they are downloaded enough.
Are Files Guaranteed To Exist For At Least 30 Days?
No, due to DMCA, abuse, migrations or policy changes, files are not always guaranteed for 30 days, but in most cases, you can simply re-download the file again if it gets deleted.
