When you acquire a Perpetual License, you receive the right to use the versions of Slint that were provided to you under the License forever.
The license is valid for all supported versions of Slint at the time of purchase and subsequent versions released within a 12 month period. As the license is perpetual, development can continue with the purchased versions forever. Commercial use of versions released after the 12 month period is possible with purchase of a new license.
We do not charge fees based on number of developers, designers, etc.. This gives you the flexibility to scale up your development team without additional cost. We only charge fixed fees for each software program or product built with the toolkit. "Product" means the end result of a software or hardware manufacturing process, which is distributed under a specific name or order code, and which incorporates software written using Slint' frameworks and/or tools. If you are marketing the same product under many different names, please contact us for custom pricing.
