Any trial is available only to eligible non-competitor users, is subject to these terms, and may be modified, suspended, or withdrawn by Supplier at any time. Except for an active trial or other written authorization from Supplier, access to and use of the Licensed Software requires a valid, paid license at all times.

4. Competitive Restrictions

4.1 Competitor Access Prohibited. You must not access, download, install, execute, inspect, evaluate, test, benchmark, or otherwise use the Licensed Software if you are developing, contributing to, advising, funding, operating, marketing, or planning a product, service, project, or technology that competes or is intended to compete with Slicer, SlicerVM, or any Supplier product or service. This restriction applies whether the competing solution is open source, source-available, proprietary, commercial, internal, hosted, self-hosted, academic, experimental, or otherwise. This restriction applies to all license tiers, subscriptions, trials, evaluations, and forms of access unless a separate written agreement signed by Supplier expressly states otherwise.

4.2 Evaluation Restrictions. Any evaluation use of Slicer or SlicerVM may only occur under a separate, written evaluation agreement executed by Supplier in its sole discretion. In the absence of such a written evaluation agreement, you must not use the Licensed Software for any evaluation, benchmarking, comparison, competitive analysis, research, or assessment purpose. A paid license, subscription, order, trial, download, possession of a license key, or other access to the Licensed Software does not grant any right to use the Licensed Software for a restricted purpose or for any activity prohibited by this Agreement.

4.3 Prohibited Competitive Use and Copying. Customer shall not use the Licensed Software or any knowledge, observations, measurements, outputs, or materials derived from the Licensed Software to design, develop, train, test, improve, market, position, document, price, compare, or validate any competing product, service, project, or technology. Without limitation, Customer shall not copy, imitate, adapt, derive from, or use Supplier's images, kernels, filesystem layouts, configurations, manifests, examples, templates, APIs, SDKs, CLI design, command structure, host-to-agent communication, guest agent behavior, storage or networking design, product flows, UI design, documentation structure, examples, diagrams, website content, or marketing prose for any competing solution. Purchasing, subscribing to, renewing, or otherwise obtaining any license or access to the Licensed Software does not waive, limit, or reduce these restrictions.

To the extent that there is any third-party software embedded in, bundled with, or otherwise provided to Customer in connection with the Licensed Software (“Third Party Software”), such Third Party Software shall be used solely with the operation of the Licensed Software and not as a standalone application or for any other purpose.
