Projeqtor is distributed as open source software: it's a free product, completely free...
Choosing it does not make you captive and you are not limited.
The downloadable version is fully functional, without limitation, and without needing to pay a premium license to get all features.
You can use and modify projeqtor under the terms of the Affero General Public License ("GNU Affero General Public License") as published by the "Free Software Foundation", version 3 of the License, or (at your option) any version later.
You can read the terms of use to verify your compliance with the copyright and free software philosophy.
So you can adapt ProjeQtOr (or have it adapted for you) as long as you respect the license.
Similarly, if you want to take advantage of our hosting service, you can at any time switch back to on premise hosting: your data will be returned to you.
