These Terms of Use ("Terms") govern your use of the Catkuro mobile application (the "App"), provided by Lobster Claw Software LLC ("we," "us," or "our"). By downloading, accessing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
1. Eligibility and Use
You may use the App only in compliance with applicable law and these Terms. You are responsible for your use of the App.
The App is not directed to children under 13. If you are under the age of majority where you live, you may use the App only with the involvement of a parent or guardian, who is responsible for any purchase made on the device.
2. License
We grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the App for your personal, non-commercial use, subject to these Terms.
3. Your Puzzle Progress
Your saved puzzles, best times, story progress, adopted cats, and settings are yours. They are stored on your device and we do not hold a copy.
Because we hold no copy, we cannot restore your progress if you uninstall the App, switch devices, or clear the App's data. Keeping your device backed up is the only way to protect it, and that is between you and your device's own backup system.
4. Purchases
The App is free and offers one optional in-app purchase, which permanently removes banner and interstitial advertising. Optional rewarded help remains available whenever you ask for it. It is a one-time purchase. There is no subscription and nothing recurring.
Billing, cancellation, refunds, and payment handling are governed by the Apple App Store or Google Play, whichever you purchased through, and by their terms rather than ours. We cannot issue refunds directly.
The purchase is tied to your Apple ID or Google account. Reinstalling the App restores it through the Restore Purchases control in Settings.
5. Advertising
The free version of the App is supported by advertising. No advertisement you did not ask for ever appears while a puzzle is open. The in-app purchase permanently removes banners and interstitial ads.
The App also offers an optional rewarded video. You may choose to watch one to reveal the selected cell, or to fill the grid with pencil-mark candidates. Deduction hints stay free and never change the board. Watching is entirely voluntary, the App asks you to confirm before the video plays, and a video you close early earns nothing. Because it is never shown unless you ask for it, it remains available after you remove banner and interstitial advertising.
Revealed cells, adopted cats, and everything else you unlock in the App are features of the App rather than property. They have no monetary value, cannot be bought, sold, or transferred, and we cannot restore them if they are lost.
6. Notifications
The App can send you occasional local reminders if you have not played for several days. These are optional, capped, and can be turned off in Settings. They are scheduled on your device and no server is involved.
7. Prohibited Conduct
You agree not to:
- use the App for unlawful, harmful, or fraudulent purposes
- reverse engineer, decompile, or attempt to extract source code, except where that restriction is prohibited by law
- interfere with the operation or security of the App
- circumvent the purchase system, advertising, or entitlement checks
- automate, falsify, or otherwise manipulate the rewarded video in order to obtain a reveal or a pencil-mark fill
- extract, copy, or redistribute the App's puzzle library or artwork
8. Intellectual Property
The App, including its design, software, branding, text, graphics, sounds, and puzzle library, is owned by Lobster Claw Software LLC or its licensors and is protected by applicable intellectual property laws.
The App includes third-party components used under their own licenses, which can be viewed from the Licenses page reachable through Settings.
9. Third-Party Services
The App relies on third-party services, including the Apple App Store, Google Play, Google AdMob, and Google Firebase. We are not responsible for those services, and your use of them may be governed by their own terms and policies.
10. Disclaimer
The App is provided on an "as is" and "as available" basis, without warranties of any kind, express or implied, to the fullest extent permitted by law. We do not guarantee that the App will be uninterrupted, error-free, or available at all times.
11. Limitation of Liability
To the fullest extent permitted by law, Lobster Claw Software LLC and its affiliates, licensors, and service providers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, profits, goodwill, or business opportunities arising out of or related to your use of the App.
To the fullest extent permitted by law, our total liability for any claim arising out of or relating to the App will not exceed the amount you paid, if any, for the App or its in-app purchase in the 12 months before the event giving rise to the claim.
12. Termination
We may suspend or terminate access to the App or certain features if required by law, by platform rules, or if we reasonably believe you have violated these Terms. You may stop using the App at any time by uninstalling it.
13. Changes to These Terms
We may update these Terms from time to time. Your continued use of the App after updated Terms take effect constitutes acceptance of them.
14. Governing Law
These Terms are governed by the laws of the jurisdiction in which Lobster Claw Software LLC operates, without regard to conflict of law principles, except where consumer protection laws require otherwise.
