IMPORTANT — READ CAREFULLY BEFORE ACQUIRING OR USING THIS SOFTWARE

This End User License Agreement ("Agreement" or "EULA") is a legally binding contract between you ("You" or "User") and thinkertankApps ("Licensor", "We", "Us", or "Our"), located in Ontario, Canada, governing your use of UltraWall, including all associated files, assets, documentation, and future updates ("Software").

BY ACQUIRING, DOWNLOADING, INSTALLING, COPYING, OR USING THE SOFTWARE, YOU ACKNOWLEDGE THAT YOU HAVE READ THIS AGREEMENT, UNDERSTAND IT, AND AGREE TO BE BOUND BY ITS TERMS AND CONDITIONS. IF A DISTRIBUTION PLATFORM PRESENTS THESE TERMS FOR ACCEPTANCE, YOUR ACCEPTANCE THROUGH THAT PLATFORM ALSO CONFIRMS YOUR AGREEMENT TO THEM.

IF YOU DO NOT AGREE TO THESE TERMS, DO NOT INSTALL OR USE THE SOFTWARE. YOU MAY REQUEST A REFUND IN ACCORDANCE WITH SECTION 8 OF THIS AGREEMENT.

1. License Grant

Subject to your acceptance of and compliance with this Agreement, thinkertankApps grants you a limited, non-exclusive, non-transferable, non-sublicensable license to install and use the Software for personal or ordinary commercial purposes on devices and accounts authorized by the Microsoft Store or Steam, as applicable (the "Distribution Platform"). Platform-authorized account or family access is not a prohibited transfer under this Agreement.

This is a license, not a sale. thinkertankApps retains all ownership rights in and to the Software.

2. Scope of License and Platform Entitlements

The number of devices, account access, family access, reinstallation rights, and other acquisition entitlements are governed by the terms and configuration of the Distribution Platform through which you acquired the Software. You may use the Software only while the applicable platform grants you access.

You may not independently transfer, sell, share, or sublicense your entitlement. This restriction does not prevent access that the Distribution Platform itself expressly authorizes, including eligible family access.

3. Restrictions

You may NOT:

  1. Copy or reproduce the Software except as required for installation or use expressly permitted by this Agreement or the Distribution Platform, or distribute, publish, sell, sublicense, or transfer the Software or any copy thereof to any third party;
  2. Modify, adapt, translate, reverse engineer, decompile, disassemble, or create derivative works based on the Software, except to the limited extent permitted by applicable law that cannot be contractually excluded;
  3. Remove, alter, or obscure any copyright notice, trademark, or other proprietary rights notice contained in or on the Software;
  4. Use the Software for any unlawful purpose or in violation of any applicable local, provincial, federal, or international law or regulation;
  5. Rent, lease, lend, or otherwise transfer access to the Software except through access expressly authorized by the Distribution Platform; or
  6. Offer the Software itself as a hosted, time-shared, service-bureau, managed wallpaper, or similar service primarily for third parties without prior written permission from thinkertankApps.

4. Permitted Commercial Use

You may use the Software for ordinary personal, professional, or organizational purposes, including on a business-owned device, subject to the Distribution Platform's purchase and device entitlements.

Permitted commercial use does not grant any right to redistribute, resell, sublicense, white-label, or provide the Software itself to third parties as a service. Those activities require prior written permission from thinkertankApps.

5. Intellectual Property and Ownership

The Software, including but not limited to all code, algorithms, user interface elements, graphics, icons, artwork, audio, video, text, documentation, and all updates, modifications, and derivative works, is and remains the exclusive intellectual property of thinkertankApps.

This Agreement does not grant you any rights to the trademarks, service marks, trade names, or logos of thinkertankApps.

All rights not expressly granted to you in this Agreement are reserved by thinkertankApps.

The Software is protected by Canadian copyright law (Copyright Act, R.S.C. 1985, c. C-42), applicable intellectual property laws, and international treaties. Unauthorized reproduction or distribution of the Software, or any portion of it, may result in severe civil and criminal penalties, and will be prosecuted to the maximum extent possible under applicable law.

6. Third-Party Components

The Software includes third-party open-source components and separately licensed proprietary redistributables. These components are subject to their own respective license terms, which are separate from and independent of this Agreement.

An inventory of third-party components and their applicable terms is provided in and the accompanying supplier license and notice files, which are distributed with the Software and installed alongside it.

Nothing in this Agreement limits, supersedes, or modifies your rights under applicable third-party license terms.

7. Updates and Upgrades

thinkertankApps may, at its sole discretion, provide updates, patches, bug fixes, or enhancements to the Software from time to time ("Updates").

Updates that thinkertankApps makes available through the same UltraWall product listing are included under the applicable Distribution Platform's terms. Separately marketed future products, editions, or services are not included unless thinkertankApps expressly states otherwise.

thinkertankApps makes no guarantee regarding the frequency, timing, or content of Updates. thinkertankApps reserves the right to modify, discontinue, or end support for the Software at any time, with reasonable notice where practicable.

8. Refund Policy

Paid public purchases of the Software are fulfilled through the Microsoft Store and Steam. Refunds are handled by the platform through which you purchased the Software, in accordance with that platform's refund policy:

  • For purchases made through the Microsoft Store: refunds are subject to Microsoft's own refund policy and are processed directly by Microsoft.
  • For purchases made through Steam: refunds are subject to Steam's (Valve's) refund policy and are processed directly through Steam.

To request a refund, use the refund process of the platform through which you made your purchase. thinkertankApps does not process payments and cannot issue refunds directly for platform purchases.

Upon receiving a refund, your license to use the Software is immediately terminated, the platform of purchase may revoke your access to the Software, and you must uninstall and delete all copies of the Software from your device.

Nothing in this Section limits any consumer rights you may have that cannot be excluded, restricted, or modified by contract, including rights under the Ontario Consumer Protection Act, 2002 (see Section 13).
