Terms of Service

Overview

These Terms of Service (“Terms”) govern your use of Kosshi (“the App”) and this website (kosshi.app), developed by Shirokuma (“the Developer”). By downloading, installing, or using the App, you agree to these Terms.

About the App

Kosshi is an outliner app for macOS and iOS. Your data is stored locally on your device, with optional iCloud sync.

Free Trial & Purchase

Kosshi offers a 7-day free trial with full access to all features. After the trial ends, the App switches to read-only mode — you can view your existing data but cannot create or edit.

To continue using all features, a one-time purchase through the App Store is required. Once purchased, you have access to all features with no additional fees.

The purchase is tied to your Apple ID and can be restored on all devices signed in with the same Apple ID.

Refunds

All purchases are processed through the App Store. Refunds are handled by Apple under their refund policy. To request a refund, contact Apple Support or visit reportaproblem.apple.com.

Data Storage

All your data is stored locally on your device. If you enable iCloud sync, your data is also stored in your iCloud account managed by Apple. The Developer does not collect, store, or access your data.

You are responsible for backing up your data. We recommend using iCloud sync or exporting your data regularly.

Disclaimer

The Developer does not guarantee that the App will function without interruption or errors. To the maximum extent permitted by law, the Developer is not liable for any damages arising from the use of the App, including loss of data or profits.

Intellectual Property

All rights to the App, including its design, code, graphics, logos, and documentation, belong to the Developer and are protected by copyright and intellectual property laws. You may not copy, modify, distribute, or reverse engineer any part of the App.

Governing Law

These Terms are governed by and construed in accordance with the laws of Japan.

Changes to These Terms

We may update these Terms from time to time. Changes will be posted on this page. Continued use of the App after changes constitutes acceptance of the updated Terms.
