End User License Agreement

ULTRAWALL — END USER LICENSE AGREEMENT (EULA)
Last Updated: September 15, 2026
Version: 1.3
Revised: September 15, 2026

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 of the proprietary Software. thinkertankApps retains its ownership rights, subject to the separately identified components and content described in Sections 5 and 6.

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

Except for third-party components and bundled Gallery content identified in the Software, its notices, or its Preview and Info surface, the Software's code, algorithms, user interface elements, product graphics, icons, text, documentation, updates, modifications, and derivative works are and remain the exclusive intellectual property of thinkertankApps.

Bundled Gallery images have their own identified rights status. The current collection identifies items as public-domain (PD) or CC0-1.0 material. thinkertankApps does not claim ownership of public-domain works or acquire a creator's rights by including an image. Any rights held by others remain with their respective holders.

Gallery images can be viewed, composed, applied as wallpapers, and copied using Save image as. Any separate use of an item is governed by its applicable rights status and terms. This Agreement does not restrict rights You have independently under public-domain status, CC0, or another applicable third-party license.

Images You select from local files or remembered folders are not bundled Gallery content. UltraWall does not determine or grant ownership, license, or other rights in those images. You are responsible for ensuring that Your use of them is lawful and does not infringe the rights of others.

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 and Bundled Content

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

An inventory of third-party software components and their applicable terms is provided in and the accompanying supplier license and notice files. Bundled Gallery item creator, source, rights label, and source/license links are provided in the local Preview and Info surface. Included JPEG images and thumbnails carry embedded credit information. UltraWall also writes the corresponding credits into generated JPEG wallpapers from the credited bundled workflow, and Save image as preserves the included image's embedded credits. External editing or use of a separately imported local copy may not preserve that association. Local-file export does not assign new Gallery rights to the file.

Credit delivery is UltraWall's documentation practice; it does not impose a new attribution condition on public-domain or CC0 material. Individual source, creator, rights and processing qualifications remain relevant. A copyright status or license does not by itself grant trademark, privacy, publicity or endorsement rights.

Nothing in this Agreement, including its copying, modification, notice-removal, refund or termination provisions, limits, supersedes, or modifies rights You hold independently under public-domain status or applicable third-party license terms. Restrictions on the proprietary Software do not override those independent rights.

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).

9. Digital Delivery and Support

The Software is delivered digitally through the Distribution Platform. No physical media or separate product key is provided. A Microsoft or Steam account and an internet connection may be required to purchase, download, restore, or update the Software. UltraWall operates offline after installation.

The Distribution Platform is responsible for billing, refunds, account access, purchase entitlements, and download or library access. thinkertankApps provides technical support for UltraWall functionality and compatibility through:


To help diagnose a problem, include your purchase channel, UltraWall version, Windows version, exact error, and reproduction steps. You may contact support or send feedback directly by email or through the website contact form. Screenshots, log excerpts and locally exported diagnostic reports are voluntary; review them first because they may contain filenames, local paths or other personal information. Settings > Report a problem creates a local text report only after confirmation and selection of a save location. UltraWall does not send or upload the report.

thinkertankApps aims to acknowledge support requests within two (2) business days and provide a substantive response within five (5) business days. These are service targets, not guaranteed resolution times.

10. Privacy

UltraWall is designed as a fully offline application. The Software processes images, settings, monitor information, file paths, and diagnostic information locally to provide its features, but does not transmit that application data to thinkertankApps or any external server.

Gallery bookmarks, remembered folder paths, appearance preferences and monitor exclusions are stored locally. User-directed image exports and diagnostic reports are saved to a location You choose. Windows services, synchronization providers and Your deliberate sharing operate under their own settings and terms. See the Privacy Policy for local storage, retained wallpaper files, cleanup and support information handling.

The purchase and delivery of the Software may involve the collection and processing of personal information by the Microsoft Store or Steam under their own policies. Please refer to our Privacy Policy, included with the Software and available at:
