Commercial use
Commercial terms for closed products and OEM editions.
You can use the GPL edition commercially when you follow the GPL. Ask about a separate license if your product needs proprietary distribution terms.
The trademark is separate
A code license does not include the Zinuto name or logo. OEM branding and claims of official approval need written permission.
It does not change the app
A commercial license changes distribution terms. It does not reveal hidden features or enable a paid mode.
