What your license lets you do
Short version: use the materials hard in your own work, including client deliverables. Do not pass the products themselves onward.
The single license covers one person. Adapt the materials, rebrand what you build from them, use them in paid client work: all fine. Sharing the files with colleagues, posting them to shared drives for others, reselling, or bundling them into your own products: not fine.
The team license (where offered) covers up to 10 people in one organization, with internal sharing among that group.
Every purchase includes all future updates to that product, free. The full license is two minutes to read and written in plain English; it is linked in the site footer.
