K-EMU: Retro games

Last updated: November 7, 2026

Effective date: 7 November 2026
App: K-EMU (Android package com.tinysol.kemu), version 1.0.0 and later
Developer: Tiny Solution ("we", "us")
Contact: tinysol.apps@gmail.com

By installing or using K-EMU (the "App") you agree to these terms. If you do not agree, do not install or use the App. Our Privacy Policy explains what the App does with data and is part of these terms.

1. What K-EMU is

K-EMU is an emulator: a player for game files that you supply. It runs .nes game files on your Android device. K-EMU is not affiliated with or endorsed by Nintendo.

2. No games included

K-EMU contains no games and no game files. We do not provide, host, link to or recommend any copyrighted games. The free homebrew games named in the store listing and in Settings, About are shown only in screenshots. They are not part of the App.

3. Your games and your responsibility

You bring your own games. You may use only game files that you have the legal right to use, for example games you made, games whose authors allow free use, or backups of games you own where the law of your country allows it. You are responsible for the files you load and for following the law and any licence that applies to them. Do not use the App to play or share pirated or unlicensed games. We are not responsible for what you load into the App.

4. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control. The App is licensed, not sold. All rights not expressly granted remain with us.

5. Price and purchases

The App is free. Version 1.0.0 contains no ads and no in-app purchases. If purchases are added later, Google Play will handle them under its terms, and these terms will be updated.

6. No account and local data

The App needs no account. Your library data, settings and saves are stored only on your device. They are lost if you uninstall the App, clear its data or lose the device, and we cannot restore them. Separately, the App sends crash reports, performance data and configuration requests to Google Firebase, as described in the Privacy Policy.

7. What you may not do

You may not:

  • copy, modify, decompile, reverse engineer or create derivative works of the App, except where the law or an open-source licence below expressly allows it;
  • sell, rent, lend or sublicense the App;
  • use the App to infringe anyone's copyright or other rights;
  • use the App for anything unlawful.

8. Intellectual property

The App, its icon, name and design are owned by Tiny Solution and protected by copyright and other laws. "K-EMU" and the App's logo are our marks. Other names and marks belong to their owners. Parts of the App are open-source software, listed in section 9.

9. Third-party notices

11. Updates and availability

We may update the App at any time to add features or fix problems, and we may discontinue the App or any part of it. When the App is online it may check for maintenance and for a minimum required version. During maintenance, or if your version is older than the minimum, the App may show a notice and stop you from using it until maintenance ends or you update. We are not obliged to provide updates or support.

12. Disclaimer of warranties

The App is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not promise that the App will be error-free, will run every game correctly or will work on every device. Emulation is not perfect, and a game may crash, lose progress or behave differently from the original.

13. Limitation of liability

To the fullest extent permitted by law, Tiny Solution will not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of data, saves or device function, arising from your use of or inability to use the App. Our total liability for any claim relating to the App will not exceed the amount you paid for it, which for version 1.0.0 is zero.

14. Health notice

Some players may experience discomfort from flashing or fast-moving images. Stop playing and rest if you feel dizzy, tired or uncomfortable.

17. Governing law

These terms are governed by the laws of Vietnam, without regard to conflict-of-law rules, and any dispute will be brought in the courts of that jurisdiction, except where mandatory consumer law gives you the right to use the courts of your own country.

18. Google Play

If you obtained the App from Google Play, the Google Play Terms of Service also apply.

19. Changes to these terms

We may update these terms. The effective date at the top shows the latest version. Continued use of the App after a change means you accept the updated terms.
