Will my Downloads/STEMs reset every month or will they stack?

Available Downloads/STEMs will reset every month.

Your STEMs and downloads do not carry over month to month and will reset on the same date that you created your account (Standard) or when you upgraded (Premium, Pro, or Business plans).

Example: If you upgraded to Pro plan on January 15th, your available free STEMs/downloads will reset the following month on February 15th.
