Common questions

How do I restore my full unlock?

Open MateCrown’s Settings and choose Restore Purchases. Use the Apple Account that made the original purchase and check your internet connection. You can also restore from the unlock screen. If access still doesn’t return, email us with what you see on screen.

The store is unavailable. What should I do?

Check that your watch has a working internet connection, then try again. Purchases and restoring access need Apple’s store services. If the message persists, contact us with your watchOS version and a screenshot. Your built-in free puzzles do not need a store connection.

How do I zoom and move around the board?

Turn the Digital Crown to zoom in or out. When zoomed in, drag the board to look around. Press and hold to see the whole position. To make a move, tap a piece and then a marked destination square.

Can I play offline?

Yes. The puzzles are included in the app. Once installed, you can play without an internet connection or an iPhone nearby. Buying or restoring the full unlock requires a connection.

What is included for free?

You can try five puzzles for free. A one-time in-app purchase unlocks the full collection of over 2,000 chess puzzles. There is no subscription. Daily puzzles outside the free selection also require the full unlock.

Where is my progress saved?

MateCrown saves progress, unfinished puzzles and preferences locally on your watch. We don’t run an account or cloud-sync service for this data. Deleting the app can remove your progress; watch backups and restores are managed by Apple.

Which devices and languages are supported?

MateCrown is an Apple Watch-only app for watchOS 11 or later. It supports English, Turkish, German, French, Spanish, Japanese and Italian, using your device’s language preferences.

Your information

Privacy policy

Last updated: October 5, 2026

The short version: MateCrown doesn’t require an account, include advertising, or use third-party analytics SDKs. Your puzzle progress stays on your watch. If you email us, we use the information you share to help you.

1. Who this policy covers

This policy explains how Cobalative handles information in connection with the MateCrown Apple Watch app and its marketing and support websites at matecrown.cobalative.com and matecrownprivacy.cobalative.com. You can contact us at info@cobalative.com.

2. Information stored in the app

MateCrown stores the information needed to keep your experience going on your device. This includes solved puzzles, attempts, mistakes, hint use, progress statistics, unfinished puzzle moves, and preferences such as board theme, difficulty and haptics. It also remembers whether you have completed the introduction.

The app does not transmit this gameplay information to Cobalative. It does not request access to your contacts, location, microphone, camera or health information. We do not use your gameplay data for advertising or tracking.

3. Purchases and Apple services

Purchases are processed by Apple through the App Store. MateCrown uses Apple’s StoreKit service to check whether you have purchased the full unlock and to restore access. We do not receive your payment card details.

Apple may process purchase, diagnostic and usage information under its own policies and your device settings. Apple may make sales reports or diagnostics available to the developer through its services. This is separate from MateCrown’s local gameplay storage. See Apple’s privacy policy for details.

4. When you contact us

If you email support, we receive your email address, the contents of your message, and any attachments you choose to send. We use this information to respond, troubleshoot problems and follow up on your request—not to add you to a marketing list.

Our email service providers may process these messages to deliver and store correspondence. We retain support information only as long as reasonably needed to address the request, maintain relevant support records, or meet legal obligations. You can ask us to delete correspondence, subject to those obligations.

5. Our websites

These websites do not include advertising trackers, analytics scripts, contact forms, or embedded third-party media. They do not set their own cookies or use browser storage. Contact links open your email application.

The websites are hosted on Netlify. Delivering and securing a website can involve processing technical request information such as IP addresses, browser details, requested pages and timestamps. Our hosting provider may process this information as part of operating its service. See Netlify’s privacy statement.

Links to Apple, Netlify or our main studio website take you to separate sites whose own privacy practices apply.

6. How information is used and shared

We use information you provide to deliver support and operate these services. Where applicable, this processing is based on providing the service you request, our legitimate interests in maintaining reliable services, or compliance with legal obligations.

We do not sell personal information or share it for targeted advertising. Information may be handled by service providers that help deliver hosting or email, or disclosed where legally required. These providers may process information in countries other than your own, under their applicable safeguards and terms.

7. Your choices and rights

You can change app preferences in Settings. Removing MateCrown from your watch removes its local app data, subject to any backups or restores managed by Apple. Purchase records remain governed by Apple’s services.

Depending on where you live, you may have rights to request access, correction, deletion, restriction or portability of personal information, or to object to certain processing. To make a request about information held by Cobalative, email info@cobalative.com. We may need to verify the request. We cannot access or retrieve gameplay information stored only on your watch.

You may also have the right to raise a concern with your local data protection authority.

8. Children’s privacy

MateCrown does not require users to submit personal information to play. We do not knowingly collect personal information from children through the app. If you believe a child has sent us personal information in a support message, contact us so we can address it.

9. Questions and changes

Questions about privacy or support? Email info@cobalative.com. You can learn more about our studio at cobalative.com.

We may update this policy as the app or our services change. The date at the top identifies the latest version. Material changes will be communicated where required.
