Terms of Service

1. Agreement

These Terms of Service are a binding agreement between you and Kopit Cal governing your use of the Kopit Cal application for macOS and the Kopit Cal website. If you do not agree, do not use the App or Site.

2. License

Kopit Cal is provided free of charge. Subject to these Terms, you are granted a personal, non-exclusive, non-transferable, revocable license to install and use the App on Macs you own or control. Use through the Mac App Store is also subject to Apple's Licensed Application End User License Agreement, which applies in addition to these Terms.

3. No purchase required

Kopit Cal is free to download and use, with no subscription and no in-app purchase. Because there is no purchase, there is no separate refund process; App Store downloads are handled entirely by Apple.

4. Acceptable use

• Do not resell, sublicense, rent, or redistribute the App.
• Do not reverse engineer, decompile, or attempt to derive source code except where the restriction is prohibited by law.
• Do not circumvent or tamper with security or update mechanisms.
• Do not use the App for any unlawful purpose or in violation of these Terms.

5. System access and third-party data

The App accesses the macOS Calendar and Reminders only with your permission, and displays public-holiday data from third-party sources (holiday-cn, Hong Kong's official feed, Nager.Date, and any iCal / webcal links you add). Those sources are provided by third parties and are subject to their own terms and availability; Kopit Cal does not guarantee their accuracy or uptime.

6. Updates

We may provide updates, bug fixes, and improvements through the Mac App Store or the app's updater. We are not obligated to provide any particular update or to support older versions indefinitely.

7. Intellectual property

The App, Site, and related content, trademarks, and software are owned by Kopit Cal or its licensors and are protected by intellectual property laws. Open-source components and data sets are used under their respective licenses.

8. Disclaimer of warranties

The App and Site are provided as is and as available, without warranties of any kind. Calendar calculations, holiday arrangements, and third-party feeds may contain errors; you are responsible for verifying dates that matter and for maintaining your own backups.

9. Limitation of liability

To the maximum extent permitted by law, Kopit Cal will not be liable for indirect, incidental, special, consequential, or punitive damages, or for missed events, loss of data, or lost profits arising from your use of the App.

10. Termination

These Terms apply until terminated. Your license terminates automatically if you breach them. Upon termination, you must stop using the App and delete all copies.

11. Governing law

These Terms are governed by applicable law without regard to conflict-of-laws rules. Disputes will be subject to courts of competent jurisdiction unless applicable law requires otherwise.

12. Changes to these Terms

We may update these Terms from time to time. The current version will be posted here with an updated Last updated date. Continued use after changes take effect constitutes acceptance.
