For the avoidance of doubt, Evaluation Purpose excludes any commercial use, competitive analysis, reverse engineering, or use in production environments. **1.3 "Intellectual Property Rights"** means all intellectual property rights worldwide, including without limitation patents, copyrights, trademarks, trade secrets, know-how, moral rights, database rights, and any other proprietary rights, whether registered or unregistered. **1.4 "Software"** means the following proprietary packages and all related documentation provided by GRID: **@grid-is/spreadsheet-engine** (a high-performance calculation engine fully compatible with Excel and Google Sheets, capable of running in-browser or server-side); **@grid-is/spreadsheet-viewer** (a JavaScript library for viewing spreadsheets in a web-based environment); and **@grid-is/spreadsheet-editor** (which extends the Viewer with comprehensive spreadsheet editing capabilities).

This includes use by AI agents, automated processes, and contractors acting on Licensee's behalf. **2.3 Attribution Requirements.** As a condition of the license granted in Section 2.1, any application, prototype, demonstration, or other solution built using or incorporating the Software ("Powered Solution") must display a "Powered by GRID" attribution notice that meets the following requirements: - **(a)** Placement. The attribution notice must appear in a location that is visible to all users of the Powered Solution — for example, in the application footer, an "About" or credits screen, or directly adjacent to any rendered spreadsheet content; - **(b)** Format. The attribution notice must use either: (i) the text "Powered by GRID" in a legible typeface and at a font size no smaller than the surrounding interface text; or (ii) the official GRID logo as made available at [https://grid.is/press-kit](https://grid.is/press-kit); and - **(c)** Prominence. The attribution notice must not be hidden, obscured, or reduced in visibility in a way that renders it less prominent than the surrounding interface elements. Licensee may request GRID's approval for an alter native attribution placement or format by contacting [legal@grid.is](mailto:legal@grid.is). Attributions are not required in commercial licenses. ## 3\.

TELEMETRY The Software sends a single anonymous ping to GRID's servers upon initialisation. This ping contains: the package name, package version, and runtime environment. No spreadsheet data, no personally identifiable information, and no usage data beyond the init event is transmitted. This ping fails silently in offline or restricted environments and does not affect the Software's functionality. Telemetry is not included in commercial licenses. ## 6\.

GENERAL PROVISIONS **10.1 Entire Agreement.** This license constitutes the entire agreement between the parties concerning its subject matter and supersedes all prior or contemporaneous agreements, understandings, and discussions, whether oral or written. **10.2 Amendments.** GRID may update these terms at any time by publishing a new version to the relevant package repository. Continued use of the Software following publication of an update constitutes acceptance of the updated terms. **10.3 Assignment.** Licensee may not assign, transfer, or delegate any of its rights or obligations under this license without GRID's prior written consent.

GRID may freely assign this license to any successor or affiliate. **10.4 Governing Law.** This license shall be governed by and construed in accordance with the laws of Iceland, without regard to its conflict of laws principles. **10.5 Severability.** If any provision of this license is held to be invalid, illegal, or unenforceable, the remaining provisions shall continue in full force and effect, and the invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable. **10.6 Waiver.** No waiver of any provision of this license shall constitute a waiver of any other provision, nor shall any waiver constitute a continuing waiver.

JURISDICTION Any dispute arising out of or relating to this license shall be subject to the exclusive jurisdiction of the District Court of Reykjavík (Héraðsdómur Reykjavíkur), Iceland. The parties irrevocably submit to the personal jurisdiction of that court and waive any objection to the laying of venue in Reykjavík, Iceland. ## 12\. SPECIAL PROVISIONS **12.1 Injunctive Relief.** Licensee acknowledges that any breach of Sections 2 (License Grant), 3 (Intellectual Property Ownership), or 4 (Software IP Protection) would cause irreparable harm to GRID for which monetary damages would be an inadequate remedy.
