What does "redistribute" mean?

The term "redistribution" in the BlackBox Open Source License means your application is distributed to one or more third parties. Giving an application to customers, even in alpha or beta releases, is redistribution. Giving contractors, affiliates, parent organizations or subsidiaries, business partners or support vendors a copy of the application is generally redistribution.

The following are not redistribution:
• Building an application for use internal or external to your organization, deployed and managed on your organization's clients or servers.
• Building a web service on top of BlackBox and making it available.
• Off-site backups or other software archival procedures.

Whether or not you charge money for your application does not matter. The only test is if you redistribute it.

Не имеет значения, берете ли вы деньги за ваше приложение или нет. Единственным критерием является его распространение.
