These Terms of Use ("Terms") govern your use of the Kakuro Haven 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.
2. Licence
We grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to use the App for your personal, non-commercial use, subject to these Terms.
3. Your Puzzle Progress
Your saved puzzles, best times, 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 advertising. 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. Advertisements never appear while a puzzle is open. Removing advertising through the in-app purchase removes it everywhere in the App.
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
- extract, copy, or redistribute the App's puzzle library
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 licences, which can be viewed from the Licences 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.
