What is the subscription model?

Customers can purchase subscription licenses for various time periods, and are entitled to use the software under the license during the agreed upon time period. When the subscription expires, the customer lose the rights to use or distribute commercial software developed with helix libraries.

Can I use one license for multiple customers or applications?

Yes. As a freelancer, digital agency, or any other kind of service provider, you can use your license to develop as many applications as you want, for as many customers as you want. However, if a customer of yours plans to use helix for commercial purposes, then they must have a valid subscription as well.

Do I have to purchase a commercial license for every user in our team?

No. A license is tied to an organization, which allows all people of the said organization to use the software.

What is the consequence of not complying with the license restrictions?

If software using helix libraries does not fully comply with the license obligations, you will lose your license and related distribution rights. It is also good to note that in most countries copyright infringement is statutory violation, not breach of contract and thus the statutory remedies apply.
