("we", "us") about the mobile app "Koi-Koi Hanafuda: Fair Play" (the "App"). By downloading or using the App you accept these terms.

1. What the App does

The App is a card game, Koi-Koi. It is for entertainment only: no money or prizes can be won, and nothing in the App is a bet. Our Privacy Policy explains how the App handles data.

2. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices that you own or control, in line with these terms and the rules of the app store you got it from.

You may not:

• copy, modify, reverse-engineer, decompile, or disassemble the App, or create derivative works from it, except where the law allows this regardless of this clause;
• rent, lease, lend, sell, redistribute, or sublicense the App;
• use the App in a way that breaks any law or the rights of others.

We may end your license if you materially breach these terms; you must then stop using the App and delete it.

The App is licensed, not sold. It is protected by copyright, and we and our licensors keep all rights that are not expressly granted to you.

3. Price and purchases

The App can be used at no cost. It offers optional one-time in-app purchases: themes, which change how the App looks, and a tip, which changes nothing in the App. Purchases are tied to your app store account.

You buy through the app store you got the App from, which takes the payment and handles taxes, receipts, and refunds under its terms.

Right of withdrawal. Under EU and Swedish law a consumer can normally withdraw from a purchase made at a distance within 14 days. For digital content this right ends once delivery has begun at your request and with your acknowledgement that you thereby lose it. A theme is delivered immediately when you buy, and the store's purchase terms contain that request and acknowledgement. Withdrawal and refund requests are handled by the store.

4. Acceptable use

Use the App only for lawful purposes. Cheating or sending false scores to the leaderboard is a breach of these terms.

5. Third-party services

The app store, the leaderboard service and your phone's backup are provided by Apple, Google, and other third parties under their own terms and privacy policies. We do not control them and are not responsible for them, including for their availability, for loss of data stored with them, or for changes they make. Charges from your mobile carrier or those services are your responsibility.

6. Warranty and liability

Apart from statutory rights, and to the extent the law allows, the App is provided "as is" without any other warranty, express or implied.

As far as the law allows, we accept no liability for any damage or economic loss arising directly or indirectly from the App, including when the App does not work as intended.

If we are nevertheless liable, our total liability is limited to the amount you paid for the App.

7. App Store and Google Play

Apple. If you downloaded the App from the App Store, the following applies in addition, as required by Apple:

• These terms are between you and us only, not with Apple. We, not Apple, are responsible for the App and its content.
• The license is limited to use on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, and may be used by other accounts associated with you through Family Sharing or volume purchasing.
• We alone are responsible for maintenance and support. Apple has no obligation to provide any maintenance or support for the App.
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price to you. To the maximum extent permitted by law, Apple has no other warranty obligation for the App.
• We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your use of it, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection, privacy, or similar law.
• If a third party claims that the App infringes its intellectual property rights, we, not Apple, are responsible for the investigation, defense, settlement, and discharge of such claim.
• You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
• You must comply with applicable third-party terms (for example your mobile carrier's terms) when using the App.
• Apple and Apple's subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

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

8. Changes to the App and these terms

We may update the App. We may also change these terms; new terms apply to new downloads and to updates that you choose to install, and we show them in the App with a new effective date. Rights you have under mandatory consumer law when digital content is changed are not affected.

9. Governing law and disputes

These terms are governed by Swedish law, excluding the UN Convention on Contracts for the International Sale of Goods and the conflict-of-law rules.

Please email hello@koikoifairplay.com first so that we can try to resolve any issue directly.

If any provision of these terms is invalid, the remaining provisions stay in force.
