Terms of service for Mattis

1. About these terms

Mattis is provided by Strange Utvikling, a sole proprietorship owned by Stian Strange and registered in Norway under organisation number 935 912 032 ("we", "us"). By downloading or using Mattis you agree to these terms.

If you got Mattis from the App Store, Apple's Licensed Application End User License Agreement also applies. If you got it from Google Play, the Google Play terms apply to your use of Google Play. If those store terms and these terms conflict for something the store handles, such as payment or refunds, the store terms apply.

2. The game

Mattis is a free digital version of the Norwegian card game Mattis, also known as Skitgubbe and Myllymatti. You can play solo against AI opponents or online with other players. Online play needs an internet connection. We may add, change or remove features, and we try to give notice before we remove a feature you paid for.

3. Age and accounts

• Mattis is made for a general audience and is not directed to children under 13.
• If you are under 18, or under the age of majority where you live, ask a parent or guardian before you buy anything in the app.
• You do not need an account to play. Signing in to Apple Game Center, Google Play Games or the hint account (with Apple or Google) is optional. Keep your devices and sign-ins secure; you are responsible for purchases made with them.

4. Purchases and subscriptions

What you can buy

• One-time unlocks: ad-free play, the Egyptian and Astronaut card themes, and the Insane AI difficulty. They stay available for as long as we offer the app on your platform, and you can restore them on a new device with the same App Store or Google Play account.
• Hints: packs of 10 or 40 hints, plus free hints we may give you. Hints are used up when you use them, have no cash value, cannot be transferred or exchanged for money, and are tied to your hint wallet. If you delete your hint account, any remaining free and purchased hints are lost and are not refunded.
• Mattis Plus: a monthly or yearly subscription with ad-free play, unlimited solo hints, all card themes (current and future) and early access to new features. The benefits are described in the app before you subscribe.

Subscriptions, trials and renewal

Mattis Plus renews automatically at the end of each period at the price shown in the app, unless you cancel before the renewal date. Where a free trial is offered (for example 7 days), the subscription starts and you are charged when the trial ends unless you cancel before then. Manage or cancel your subscription in your App Store subscriptions or Google Play subscriptions. Cancelling stops the next renewal; you keep Plus until the end of the period you paid for. Deleting the app does not cancel a subscription.

Payment, prices and refunds

The App Store and Google Play handle all payments, prices in your currency, taxes and refunds. Ask for a refund through the store you paid with. We cannot issue store refunds ourselves.

Your consumer rights

When you buy digital content that is delivered at once, such as hints or an unlock, you agree that delivery starts straight away, and you acknowledge that you then lose the 14-day right of withdrawal under consumer law. This does not affect your statutory rights if a purchase is faulty or not delivered: contact us or the store and we will put it right.

5. Advertising

The free version of Mattis shows ads from Google AdMob. Ad-free play and Mattis Plus remove them. How ads use data, and your choices, are described in the privacy policy.

6. Fair play

When you play Mattis, especially online, you agree not to:

• choose a display name that is offensive, impersonates someone, or contains personal information about anyone;
• cheat, exploit bugs, use bots or automation, or interfere with other players' games;
• copy, decompile, reverse engineer or modify the app, except where the law allows it;
• attack, overload or try to gain unauthorised access to our servers;
• use Mattis for anything illegal.

If you break these rules, we may remove your display name, end a match or block access to online play. Where it is reasonable, we will tell you why.

7. Ownership

The app, its design, card art and other content belong to Strange Utvikling or its licensors. We give you a personal, non-exclusive, non-transferable licence to use Mattis on devices you own or control, for non-commercial use. The traditional rules of the card game belong to everyone.

8. Other services

Mattis works with services run by others, such as Apple Game Center, Google Play Games, Sign in with Apple or Google, the App Store and Google Play. Their own terms apply to your use of them, and we are not responsible for those services.

9. Availability

We work to keep Mattis running, but online features can be unavailable at times, for example during maintenance or outages. We may stop offering Mattis. If we do, we will give reasonable notice on playmattis.app or in the app, and you keep your rights under consumer law for purchases you have already made.

10. Liability

Nothing in these terms limits liability that cannot be limited by law, such as liability for intent or gross negligence, for personal injury, or under mandatory consumer protection rules. Apart from that, we are not liable for indirect losses, such as lost profits or lost data, and our total liability to you is limited to the amount you paid us in the 12 months before the claim.

11. Ending your use

You can stop using Mattis at any time by deleting the app. You can delete your hint account in the app; see the account and data deletion page. Remember to cancel any Mattis Plus subscription in the store. We may suspend online access if you seriously or repeatedly break these terms.

12. Privacy

The privacy policy explains how we handle personal data.

13. Changes to these terms

We may update these terms when the game or the law changes. We post the new version here and change the date at the top. For changes that affect you significantly, such as changes to paid features, we will give notice on playmattis.app or in the app before they take effect. If you do not agree, you can stop using Mattis and cancel any subscription.

14. Law and disputes

These terms are governed by Norwegian law. If you are a consumer living in another country, you keep the protection of the mandatory consumer laws there, and you can bring a claim in the courts where you live.

If something goes wrong, contact us first and we will try to solve it. Consumers in Norway can also ask Forbrukerrådet to mediate and take the case to the Consumer Complaints Board (Forbrukerklageutvalget).
