Ikiwa - End User License Agreement
Last updated: 7 November 2026
This End User License Agreement ("Agreement") is between you and the developer of Ikiwa ("Licensor") and governs your use of the Ikiwa application, including its game engine, neural network files, graphics, sounds and updates (the "App"). By installing or using the App you agree to this Agreement. If you do not agree, do not install or use the App.
1. License
Subject to this Agreement, Licensor grants you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices that you own or control, as permitted by the rules of the store from which you obtained it.
2. Ownership
The App is licensed, not sold. Licensor and its licensors keep all rights, title and interest in the App, except for the third-party components described in Section 4, which belong to their respective owners.
3. Restrictions
Except as allowed by Section 4 or by applicable law that cannot be waived by contract, you may not:
- copy, modify or create derivative works of the App;
- decompile, disassemble or reverse engineer the App;
- rent, lease, sell, redistribute or sublicense the App;
- remove or alter any copyright, license or attribution notice in the App.
4. Open source components
The App includes third-party open source software. Each component is licensed to you under its own license, listed with its copyright notice and full license text in the App under Settings > About. Those licenses govern your use of those components, and nothing in this Agreement restricts, limits or otherwise affects the rights they give you.
In particular, the App uses libraries licensed under the GNU Lesser General Public License version 3 ("LGPL"), including the Qt framework. For those libraries, and notwithstanding Section 3, you may modify them, replace them in the App with a modified version, relink them with the App, and reverse engineer the App to the extent needed to debug such modifications. The complete corresponding source code of those libraries is available as described in the App.
5. Updates
Licensor may provide updates, which are covered by this Agreement unless they come with their own terms. Licensor has no obligation to provide updates or support.
6. In-app purchases
The App offers optional one-time purchases through the store from which you obtained it, currently "Remove ads" and "Pro" (no ads, plus Kifu). A purchase gives you a license, under this Agreement, to use the related features of the App; it does not transfer ownership of them. Purchases belong to your store account, not to a device, and are restored when you install the App again with the same account. Payments, cancellations and refunds are handled by the store under its own terms. A one-day trial unlocked by watching an ad ends automatically. Nothing in this section limits rights that consumer law gives you.
7. Disclaimer of warranties
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. Move suggestions, game evaluations and ranks produced by the App's engine are estimates and may be wrong, and positions read from photos may contain mistakes.
8. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS OR REVENUE, ARISING FROM YOUR USE OF THE APP. LICENSOR'S TOTAL LIABILITY WILL NOT EXCEED THE AMOUNT YOU PAID FOR THE APP AND ITS IN-APP PURCHASES, OR USD 0 IF YOU PAID NOTHING.
9. Termination
This Agreement ends automatically if you breach it. On termination you must stop using the App and delete it. Sections 2, 4, 7, 8 and 11 survive termination.
10. Apple App Store
If you obtained the App from Apple's App Store: this Agreement is between you and Licensor only, not Apple; Apple has no obligation to provide maintenance or support for the App; to the extent any warranty applies and the App fails to conform to it, you may notify Apple, which will refund the purchase price, and Apple has no other warranty obligation; Licensor, not Apple, is responsible for any product claims and any third-party claim that the App infringes intellectual property rights; you represent that you are not located in a country subject to a U.S. Government embargo or listed on a U.S. Government list of prohibited or restricted parties; and Apple and its subsidiaries are third-party beneficiaries of this Agreement and may enforce it against you.
11. General
This Agreement is governed by the laws of the Socialist Republic of Vietnam, without regard to its conflict of laws rules. If any provision is held unenforceable, the rest remains in effect. This Agreement is the entire agreement between you and Licensor about the App.
