Terms of Service

Version: 2.0.0Effective Date: 2026-08-14Last Updated: 2026-08-14

Article 1 (Application)

These Terms of Service (the "Terms") govern the use of Furikaeri Nikki (the "App"). By downloading or using the App, you agree to these Terms.

Article 2 (Service Description)

The App is a diary application for recording and reflecting on daily events and thoughts. It provides features such as creating, editing, deleting, and reviewing diary entries, reminders, widgets, customization, optional accounts, and cross-device sync. Some features are available free of charge, while additional features may be offered through a paid plan. The current set of included features is shown on the in-app purchase screen.

Article 3 (Paid Plans and Auto-Renewal)

The following conditions apply to paid plans:

  • The App may offer paid plans as monthly or annual auto-renewing subscriptions.
  • The plan name, subscription period, price, any trial period, and other conditions are displayed on the in-app purchase screen before confirmation. The localized price shown by the app marketplace takes precedence.
  • When you confirm a purchase, payment is charged to your app marketplace account.
  • A subscription automatically renews for the same period unless canceled through the app marketplace settings before the current period ends.
  • After cancellation, paid features generally remain available until the end of the paid period. Deleting the App, signing out, or deleting your App account does not cancel the subscription.
  • You can manage or cancel a subscription from the subscription settings of the app marketplace account used for the purchase.
  • You may use Restore Purchases to recheck purchases associated with the same app marketplace account.
  • Refunds, billing, price changes, and subscription periods are governed by the applicable app marketplace terms and applicable law.

Article 4 (Accounts and Data Management)

Accounts and data are handled as follows:

  • Diary data and settings are primarily stored on your device.
  • Sync is off by default. If you sign in and enable sync, eligible data is transmitted to and stored on external infrastructure required to provide the feature and is synchronized across devices using the same account.
  • The developer and service providers may process information as necessary for authentication, synchronization, purchase verification, maintenance, and legal compliance. See the Privacy Policy for details.
  • Uninstalling the App deletes local data but does not automatically delete synced data or subscription information. You may request deletion of the cloud account and synced data through the in-app account deletion feature.
  • Deletion of diary entries or other data by the user cannot be undone within the App. If sync is enabled, the deletion is also applied to other devices using the same account and to synced data in the cloud. Deleted data cannot be restored, including data removed by mistake, so we recommend keeping your own copy of anything important beforehand.
  • Data may be lost due to communication failures, device failure, App deletion, or other circumstances. The developer does not guarantee data integrity, permanent storage, or immediate synchronization across all devices.

Article 5 (Prohibited Activities)

You must not:

  • Violate applicable law or public order;
  • Interfere with operation of the App, servers, or networks;
  • Attempt unauthorized access, impose excessive loads, or bypass security controls;
  • Copy, modify, or reverse engineer the App except where permitted by applicable law;
  • Infringe the rights or interests of others; or
  • Engage in other conduct that the developer reasonably determines to be inappropriate for operation of the App.

Article 6 (Intellectual Property)

Copyrights, trademarks, and other intellectual property rights in the App belong to the developer or their respective owners. Rights in diary entries and other content entered by users remain with the user or the applicable rights holder.

Article 7 (Disclaimer and Limitation of Liability)

The App is provided subject to the following limitations:

  • The App is provided "as is." The developer does not guarantee uninterrupted availability, error-free operation, or fitness for a particular purpose.
  • Except in cases of willful misconduct or gross negligence, the developer is not liable for indirect, special, or consequential damages, lost profits, or data loss (including loss resulting from deletions performed by the user) arising from use of or inability to use the App.
  • If applicable consumer protection or other mandatory law does not permit a limitation in this Article, that law prevails.

Article 8 (Changes, Suspension, and Termination)

The developer may change, suspend, or terminate all or part of the App for maintenance, security, legal compliance, or service improvement. Material changes affecting paid features will be announced in advance through a reasonable method unless an urgent response is required.

Article 9 (Changes to These Terms)

The developer may update these Terms due to legal changes, App changes, or other necessity. Material changes will be announced in the App or on the developer's website. Updated Terms apply from the stated effective date.

Article 10 (Governing Law and Jurisdiction)

These Terms are governed by the laws of Japan. Unless otherwise required by applicable law, the Tokyo District Court has exclusive jurisdiction as the court of first instance for disputes relating to the App.
