Terms of Service
1. Acceptance
By downloading or using HachiCalendar ("the App", "the Service"), you agree to these Terms of Service. If you do not agree, do not use the Service.
2. The Service
HachiCalendar is a calendar and schedule app. It lets you create and manage events and memos, reschedule by dragging, sync across devices with a Hachi account, share calendars with others, and use Hachi AI to add or analyze events. We may add, change or remove features over time.
3. Your account
- You can use the App without an account. Syncing and sharing require a Hachi account.
- Provide an email address you control and keep your password secure.
- You are responsible for activity under your account. Tell us promptly if you believe it has been used without your permission.
- You can delete your account at any time in the App or by emailing us.
4. Your content
You own the events, memos and other content you add to the App. You give us permission to store, process and transmit that content only as needed to provide the Service to you, for example to sync it to your devices, share it with people you choose, and send it to AI model providers when you use Hachi AI. Our Privacy Policy explains how we handle it.
5. Shared calendars
When you share a calendar, the people you invite can see its content, and change it if you give them edit access. Only share content you have the right to share.
6. Hachi AI
Hachi AI uses third-party large language models. Its results are generated automatically and may be incomplete or wrong. Check events and other results before relying on them, especially for important appointments.
7. Acceptable use
You agree not to:
- Use the Service for anything unlawful, or to harass or harm others
- Attempt to access accounts, data or systems without authorization
- Interfere with or overload the Service, or use automated means to access it in ways it is not designed for
- Copy, modify, reverse engineer, resell or redistribute the App, except where the law allows
8. License
Subject to these Terms, we grant you a personal, non-exclusive, non-transferable license to use the App on devices you own or control. If you downloaded the App from the App Store, Apple's Standard License Agreement also applies.
9. Third-party services
The App works with services provided by others, such as the App Store, the calendars on your device, and AI model providers. Their own terms apply to those services, and we are not responsible for them.
10. Disclaimer
The Service is provided "as is" and "as available". To the extent permitted by law, we make no warranties of any kind, express or implied, including that the Service will be uninterrupted, error-free, or that reminders will always be delivered. Keep your own record of anything critical.
11. Limitation of liability
To the extent permitted by law, we are not liable for indirect, incidental, special or consequential damages, or for loss of data, profits or opportunities, arising from your use of the Service. Nothing in these Terms limits liability that cannot be limited under applicable law.
12. Suspension and termination
You may stop using the Service at any time. We may suspend or end your access if you break these Terms or if needed to protect the Service or other users. Where reasonable, we will tell you beforehand.
13. Governing law
These Terms are governed by the laws that apply to the developer of the App, without regard to conflict-of-law rules. If you are a consumer, you keep any protections that the mandatory laws of your country of residence give you.
14. Changes to these Terms
We may update these Terms. We will post the new version on this page and update the date above, and for significant changes we will also notify you in the App. If you keep using the Service after changes take effect, you accept the new Terms.
