VL.Rhino

Last updated: 20.05.2026

This End User License Agreement (“Agreement”) governs the use of the software component VL.Rhino (“Software”) developed and distributed by:

Wolf Moritz Cramer
Hamburg, Germany
hello@wolfmoritzcramer.de
(“Licensor”)

By downloading, installing, or using the Software, you agree to the terms of this Agreement.
The Software is licensed, not sold.

1. License Structure

The Software may be provided under different license types:

  • Commercial Licenses (Individual, Studio)
  • Academic / Non-Commercial Licenses (Student)
  • Free or Evaluation Licenses (if applicable)

The rights granted depend on the specific license acquired.
The Software is licensed, not sold.

2. Definitions

Developer Seat means one natural person authorized to use the Software for development purposes (creating, modifying, and testing patches in vvvv gamma).

Deployment Device means one physical or virtual machine on which the Software is loaded and executed at runtime, including:

  • machines running vvvv gamma with the Software loaded as a NuGet library
  • machines running an exported executable (.exe) that includes the Software

Development machines used by a licensed Developer Seat count as Deployment Devices.

Commercial Use means any use:

  • in exchange for payment
  • within a commercial entity
  • in client projects
  • in revenue-generating activities
  • in connection with professional services

Non-Commercial Use means use exclusively for:

  • personal study
  • teaching
  • academic research
  • non-profit activities without commercial advantage

Organization means a single legal entity (e.g., a company, studio, or institution).

3. Commercial Licenses

Commercial licenses grant the right to:

  • use the Software for commercial and non-commercial projects
  • install and run it on the number of Developer Seats and Deployment Devices defined by the license type
  • receive feature updates during the purchased update period (1 year of updates included)

Individual License

  • 1 Developer Seat
  • Up to 3 Deployment Devices total (including the developer’s own machine)
  • Commercial use permitted
  • 1 year of updates included

Studio License

  • Up to 5 Developer Seats within one Organization
  • Up to 10 Deployment Devices total (including all developers’ machines)
  • All seats must belong to the same Organization
  • Seats may be reassigned to other members of the same Organization
  • Commercial use permitted
  • 1 year of updates included

Larger deployments: If your project requires more Developer Seats or Deployment Devices than included in the Studio License, please contact hello@wolfmoritzcramer.de to discuss a custom license. The Licensor offers fair, project-based pricing for large installations and enterprise use.

4. Deployment Devices — Detailed Terms

The Deployment Device count applies to all machines on which the Software is loaded and executed, regardless of context:

  • machines running vvvv gamma (development environment) with the Software loaded
  • machines running an exported executable that includes the Software
  • physical, virtual, or cloud-based machines
  • short-term and long-term deployments (e.g., temporary event installations and permanent installations both count)

A Deployment Device counts as one device per physical or virtual machine. Multiple users on the same device do not multiply the count.

Deployment Device limits are intended as fair-use guidance and rely on the Licensee’s honest declaration, consistent with the broader vvvv community trust model. The Licensor reserves the right to request reasonable information about deployment scope in case of significant doubt.

5. Academic / Non-Commercial License (Student)

If the Software is provided under the Student License or otherwise designated as “Academic”, “Educational”, or “Non-Commercial”, the following applies:

The Software may only be used:

  • within a recognized educational institution
  • for teaching or academic research
  • for personal study purposes

The Software may not be used:

  • for commercial projects
  • for paid client work
  • within commercial entities
  • in any context involving direct or indirect commercial advantage

If the Software is used commercially, a valid Commercial License must be purchased.

The Licensor reserves the right to request proof of academic eligibility at any time.

The Student License is distributed as a separate NuGet package (VL.Rhino.EDU) containing a non-commercial license marker. It is not interchangeable with the commercial package.

Student License scope: 1 Developer Seat, 1 Deployment Device (the student’s own machine).

6. Free / Evaluation License (if applicable)

If the Software is provided as a trial or evaluation version:

  • it may be time-limited
  • it may be feature-limited
  • it is restricted to non-commercial evaluation purposes

Commercial use requires purchase of a Commercial License.

7. License Restrictions

You may not:

  • distribute, sublicense, rent, or resell the Software
  • upload the Software or its files to public repositories (including but not limited to public GitHub repositories or NuGet.org)
  • make the Software publicly accessible via download links, shared storage, or any other means
  • share account credentials or download access with unauthorized parties
  • remove, alter, or obscure any copyright notices or license information
  • use the Software in any way that violates applicable law

Reverse engineering is permitted only to the extent required by mandatory law.

8. Updates and Maintenance

Each license includes one (1) year of software updates from the date of purchase.

Security updates required by applicable law may be provided independently of the update period.

After expiration of the update period:

  • previously downloaded versions remain fully usable
  • access to newer versions requires renewal or purchase of an eligible license

Update renewals are available at a reduced rate and do not affect the perpetual right to use the last downloaded version.

9. Intellectual Property

All intellectual property rights remain exclusively with the Licensor.
No ownership rights are transferred by this Agreement.
