By using CipherHeart Sudoku (the "App"), you agree to these Terms of Service. If you do not agree, please do not use the App. The App is provided by ToccaTech.
CipherHeart Sudoku is a free, browser-based puzzle generator. No account or login is required. The sequences and symbols you enter are used solely to generate your puzzle in your browser — nothing is stored on our servers. The App is provided for entertainment purposes only.
You may use the App for personal, non-commercial purposes. You may not attempt to reverse-engineer, scrape, or abuse the App or its infrastructure. We reserve the right to block access if we detect misuse.
The App, its design, and its code are the property of ToccaTech. Puzzles you generate are yours to use freely for personal purposes.
The App is provided "as is" without warranties of any kind, express or implied. We do not guarantee that the service will be error-free, uninterrupted, or available at all times.
To the extent permitted by law, ToccaTech is not liable for any damages arising from your use of, or inability to use, the App or its content.
The App displays advertisements served by Google AdSense. We do not endorse any advertised products or services. See our Privacy Policy for information on advertising cookies.
We may update these Terms at any time. The "Last updated" date at the top of this page will reflect any changes. Continued use of the App after changes constitutes acceptance of the updated Terms.
These Terms are governed by the laws of the Netherlands.
