— Software Licensing
Licensing is managed inside the software.
Clear terms for every application.
Each RJF application includes an integrated licensing system. Users can review license options, activate Student Monthly or Lifetime access, restore an existing license, and validate the assigned device directly inside the selected application.
/ License Models
License models available inside the apps
Student Monthly License
Monthly access for the selected RJF application. Intended for students, training, and lower-cost individual use. Subscription activation and status are handled inside the app.
Lifetime License
Lifetime access for the selected RJF application. Pay once and use the app on the assigned Windows device. License activation, restore, and device validation are handled inside the app.
For team, company, or site licensing, contact support with your team size and intended use case.
You may
Install and run the licensed application on the assigned Windows device. Use calculation outputs and generated reports for learning, professional engineering work, internal documentation, and client deliverables according to the selected license type.
What app licensing covers
You may not
Redistribute, sublicense, resell, share the installer, share the license key, reverse-engineer, or modify the application. A single-user license may not be used as a shared terminal, networked workstation, or multi-user company license.
These terms explain how application licenses are used after activation inside the selected software.
Scope of outputs
Outputs are preliminary engineering calculations. They support engineering judgment; they do not replace final review or sign-off by a qualified professional. See the Technical Disclaimer for full scope and method limitations.
