You own your work, and the license ends when you leave
Seller terms are readable before you apply. The platform gets only the license it needs to sell your resources, and it ends when you leave, except so past buyers keep what they bought. Your files are never used to train AI that creates competing resources, or sold or licensed to anyone who would.
Ask: What license do I grant, does it end when I leave, and will my files ever train AI that makes resources?
