As stated in your music license EULA, once purchased you should ensure you use your license (e.g. publish your video) within 6 months of the license purchase date.
The license itself is valid forever! The majority of our licenses are granted in perpetuity so there’s no danger of your video ever being taken down. (Yay!)
There is one small exception to this... which is that Universal Music Group (UMG) reserves the right to potentially choose to reapply claims after 5 years.
However, even if they did this, it would not result in a video takedown.
If for any reason you choose to delete your Lickd account... no sweat! Your licenses will still remain valid according to the conditions mentioned above.
