Terms of Service

Welcome to Hibiki

These Hibiki Terms of Service (the “Terms”) form an agreement between you and the developer of this app (“we”, “us”, or “our”) regarding your download, installation, and use of our products and services. Please read and understand these Terms before using our products and services.

Hibiki is a diary and life-recording tool. The current version includes daily tile-based journaling, daily sleep records, monthly to-dos, a calendar, and iCloud sync.

Scope and acceptance

By installing or using the App, or accessing websites and services related to it, you agree to:

• these Terms; and
• the App’s Privacy Policy, which is incorporated into these Terms by reference.

We may revise these Terms for business, legal, or other reasonable reasons. Revised Terms take effect once published. Please review them periodically. If you do not agree with an update, stop using the App and related services immediately.

Rules of use

You must follow these rules:

• Do not modify, adapt, crack, decompile, disassemble, reverse engineer, or otherwise attempt to extract the App’s source code or technical logic. Do not extract or use resources contained in the App, including images, fonts, audio, or data files, without authorization.
• Do not use the App for unlawful activity or conduct contrary to public order or good morals, including publishing unlawful information, infringing others’ rights, distributing unlawful or harmful content, or disrupting the normal operation of the service.
• Do not attempt to bypass, interfere with, or damage the App’s security mechanisms, permission controls, authentication flows, or other system functions, or exploit software vulnerabilities maliciously.
• If you are a minor, use the App with the knowledge, consent, and guidance of your guardian. Guardians should fulfill their legal responsibilities and ensure that minors use the App reasonably and lawfully.

Any content you create, enter, or save in the App must comply with applicable laws and regulations, and must not include:

• content that endangers national security, discloses state secrets, subverts state power, or undermines national unity;
• violence, pornography, gambling, or other unlawful content or content contrary to public order and good morals;
• content that infringes intellectual property, trade secrets, portrait rights, privacy rights, or other lawful rights of others; or
• any other content prohibited by applicable laws and regulations.

All content displayed in the App, including interface designs, graphics, text, audio, and trademarks, is owned by us or the relevant rights holders and protected by applicable laws. You may not copy, modify, distribute, sell, or use it commercially without authorization.

Your content and intellectual property

We value your privacy. Diary text, sleep notes, to-dos, and other records that you create, enter, or save in Hibiki are stored on your device by default. If you enable iCloud sync, records are synced to your private Apple iCloud database. Sync depends on Apple services, network access, device settings, and storage availability; it may be delayed, temporarily unavailable, or encounter conflicts. Hibiki does not promise real-time or error-free sync.

We do not use your content for advertising, sell your content, train public models with it, or provide or disclose your diary text to third parties. You are responsible for ensuring that content you create is lawful and for any resulting liability.

You may choose whether to grant location and health-data permissions. Denying or withdrawing permission does not prevent core journaling features, but weather, city-level location summaries, or step-count displays may be unavailable. See the Hibiki Privacy Policy for details.

Weather, geocoding, in-app purchases, and iCloud are provided or supported by Apple, Open-Meteo, or other necessary third parties and are subject to their own terms and privacy rules.

Please protect your device, device-unlock credentials, and Apple Account. We cannot restore content that becomes inaccessible because of a lost device, deletion, Apple Account changes, or sync-setting changes.

Installation, removal, and updates

Download and install the App correctly for your device and system requirements to help ensure complete and stable functionality.

If you stop using the App, you may remove it using your device’s uninstall function. Removal may delete local data. If you have not enabled iCloud sync or made a backup, please proceed carefully.

We may update the App from time to time to improve performance, fix issues, and improve the experience, including feature upgrades, interface changes, security enhancements, and system-compatibility improvements. You understand that you may receive update prompts. We recommend keeping the App up to date. Declining updates may affect the normal operation of some features.

Hibiki PRO, purchases, and refunds

Hibiki provides free features and PRO features. Hibiki PRO is currently a one-time, non-consumable App Store purchase.

All purchases are processed by Apple through the App Store. We do not collect or store your full payment-card information. Purchases, billing, taxes, refunds, cancellations, and restore purchases are governed by Apple Media Services Terms and App Store rules.

Purchased entitlements can usually be restored with the “Restore Purchases” feature using the same Apple Account, subject to Apple purchase records, region, Family Sharing eligibility, and system limitations.

Unless applicable law requires otherwise, Apple handles refunds under its rules. If you have a purchase issue, first try restoring your purchase. If the problem remains, contact us through the support email and do not send diary text, location coordinates, or other unnecessary sensitive information.

Disclaimers

Hibiki is a personal recording tool. It does not provide medical, mental-health, diagnostic, treatment, legal, financial, or emergency services. Nothing in the App constitutes professional advice.

You understand and agree that we do not guarantee uninterrupted, error-free, absolutely secure service or compatibility with every device. We are not liable for service interruption or data loss caused by force majeure, such as attacks or network outages, or by causes not attributable to us.

Changes to these Terms

We may update these Terms. After an update, we will notify you prominently in the App. If you continue using the App after an update, you acknowledge that you have read, understood, and accepted the updated Terms.
