Terms of Sale

Last updated: November 11, 2026

These terms apply when you buy OSK Pro or OSK Pro Studio. The free OpenStarterKit stays under the MIT License.

Who sells

Orders are handled by Polar (polar.sh), our merchant of record: the payment, the invoice and the taxes go through them. OSK Pro is made by Michele Canini, in Italy. Questions: hello@openstarterkit.dev.

What you buy

A one-time license to OSK Pro, under the OSK Pro License: Pro for one person, Pro Studio for one organization. Nothing renews.

Prices are in US dollars on /pro. Taxes are calculated at checkout, from your country.

Delivery

Right after the payment you can download OSK Pro, from the confirmation page and from your Polar customer portal: a zip archive of the code and a git bundle of the repository. No GitHub account is needed.

If you use GitHub, connect your GitHub account in the customer portal and you receive an invite to the private repository. With Pro Studio, the other people of your organization are added to the repository on request, up to the number the license allows.

Each new version is added to your downloads and to the repository.

Updates and support

Updates are included for life, as the license describes. Planned features are not part of the purchase until they ship. Support is by email and on a private Discord.

Refunds

Within 14 days of your purchase, email us and we refund it in full. A refund ends the license and removes your access to the repository and to your downloads. You must then delete the copies you made, as the license says. Your rights as a consumer under the law of your country are not affected.

Everything else

The license sets out what you may do with OSK Pro, when it ends, the limits of liability and the governing law. We will post any change to these terms here, with a new date at the top; the terms in force when you buy are the ones that apply.
