You license the software. You do not join someone else's brand.

Each product has its own license on the product page. This page is the store-wide baseline.

What a license is

A purchase is a license to use the software described on that product page, on the terms stated there. Source code, white-label use, and resale are included only when that page says they are.

What it is not

It is not affiliation, endorsement, or a right to use another company's name, logo, or screenshots.

Hosting, domains, payment gateways, maps, and messaging providers stay on your accounts and their bills.
