By installing, copying, accessing, or otherwise using the Software, Licensee agrees to be bound by the terms of this Agreement. The Software is licensed, not sold.
1. License Grant
Subject to compliance with this Agreement and payment of applicable fees, Licensor grants Licensee a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the Software solely for internal development purposes.
2. Named Seat License
2.1 Per Named Individual
The Software is licensed on a per named seat basis. Each seat must be assigned to one specific natural person (“Seat Holder”). Only the designated Seat Holder may install, access, or use the Software.
2.2 Seat Requirement
A seat is required for each individual who accesses, opens, or works within the Unity Editor on any project that includes the Software, regardless of whether such individual directly interacts with the Software’s features. Seat requirements apply whether use is direct, indirect, incidental, passive, or through integrated editor functionality.
2.3 Seat Reassignment
Seats may be reassigned only if the prior Seat Holder permanently ceases using the Software. Temporary sharing, rotating access, or concurrent use of a single seat by multiple individuals is strictly
prohibited.

3.1 Subscription Requirement
If Licensee’s organization has, within the preceding twelve (12) months, generated more than USD $200,000 in gross annual revenue or received more than USD $200,000 in funding or investment capital, Licensee must maintain an active paid subscription for each required seat.
3.2 Definition of Funding
“Funding” includes venture capital, angel investment, publisher advances, grants, crowdfunding proceeds, debt financing, equity financing, or any other external capital infusion.
3.3 Responsibility to Upgrade
Licensee is solely responsible for monitoring its revenue and funding levels and must obtain the required subscription immediately upon exceeding the threshold. Failure to maintain a required subscription constitutes a material breach of this Agreement.
4. Subscription Benefits
During an active subscription period, Licensee is entitled to continued use of the Software, access to the Software’s source code, and all updates, upgrades, patches, and fixes released during the subscription period.
