How buying and trials work
Each app is a one-time purchase or a free app with a one-time upgrade, handled by the Microsoft Store: no subscriptions and no separate licence keys. The paid apps have a 7-day free trial; SheetCabinet and Estimate Template & Invoices are free to use with limits and unlock the rest with one in-app purchase. Your purchase is tied to your Microsoft account, so it restores on every PC you sign in to, and refunds go through Microsoft.
Private by design
None of these apps has an account, ads or analytics. PixFerry makes no network connections at all, the games don't even ask for internet access, and the business apps keep your documents in your Documents folder with a backup file you control. If you also use our phone apps or websites, nothing is shared between them.
