This library (UniDoc unioffice) has a dual license, a commercial one suitable for closed source projects and an AGPL license that can be used in open source software.
Depending on your needs, you must choose one of them and follow its policies. A detail of the policies and agreements for each license type are available in the LICENSE.COMMERCIAL and LICENSE.AGPL files.
In brief, purchasing a license is mandatory as soon as you develop activities distributing the unioffice software inside your product or deploying it on a network without disclosing the source code of your own applications under the AGPL license. These activities include:
- offering services as an application service provider or over-network application programming interface (API)
- creating/manipulating documents for users in a web/server/cloud application
- shipping unioffice with a closed source product
Please see pricing to purchase a commercial license or contact sales at [email protected] for more info.
