App Declutter — Terms of Use

Effective date: August 22, 2026
Last updated: August 22, 2026

These Terms of Use ("Terms") govern your use of the iOS app "App Declutter" (Japanese name: アプリ断捨離; the "App"), provided by Yuya Sato (the "Operator"). By downloading or using the App, you agree to these Terms.

Article 1 (Relationship to Apple's Standard EULA)

The software license for the App is Apple's standard Licensed Application End User License Agreement (the "Standard EULA"). These Terms supplement the Standard EULA; if these Terms conflict with the Standard EULA, the Standard EULA prevails.
Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
These Terms are an agreement between you and the Operator. Apple Inc. ("Apple") is not a party to these Terms and is not responsible for the App or for providing maintenance or support for it.
As set out in the Standard EULA, Apple and its subsidiaries are third-party beneficiaries of these Terms and have the right to enforce these Terms against you.

Article 2 (What the App Does)

The App watches, on your device and using iOS Screen Time features, the usage of apps that you yourself select, and shows apps for which no use has been confirmed for the number of days you set (7, 14, 30, or 60 days) as "declutter candidates."
The App does not include the following:
- Automatically deleting other apps (you delete apps yourself using standard iOS operations)
- Automatically listing all apps installed on your device
- Judging usage that occurred before you started watching (past usage history cannot be evaluated retroactively)
The App runs on iPhone with iOS 17.0 or later.

Article 3 (Fees, Purchases, and Refunds)

The App is free to download, and the free tier lets you watch up to 3 apps at the same time.
A one-time in-app purchase, "Unlimited Apps," removes the limit on the number of watched apps. The price is as displayed on the App Store. It is a one-time purchase with no recurring charges and no subscription.
Purchases and payment are handled through Apple's App Store. If you change devices or reinstall the App, you can restore the purchase from "Restore Purchases" in the App while signed in with the same Apple Account used for the purchase.
Refunds are decided by Apple. The Operator does not hold your payment information and cannot process refunds directly. To request a refund, please contact Apple at https://reportaproblem.apple.com/.

Article 4 (How Judgments Are Made, and Cautions)

The App's "unused" judgment is an approximation based on whether the target app was confirmed to have been used for a total of at least 1 minute in a day. The display may differ from your actual usage in cases such as:
- Total use in a day of less than 1 minute (that day is not recorded as "use confirmed")
- Usage not being recorded due to the specifications, malfunctions, or setting changes of iOS Screen Time features
"Declutter candidates" are suggestions only. The decision to delete an app, and the deletion itself, are your own responsibility. The Operator is not responsible for the fact that a deleted app or its in-app data cannot be restored. Before deleting an app, we recommend checking for and migrating any data you need from it.
The weekly reminder notification may be delayed or may not arrive depending on the state of your device and the behavior of the OS.

Article 5 (Intellectual Property)

All intellectual property rights in the App and its components (program, design, text, logos, etc.) belong to the Operator or to third parties holding legitimate rights.

Article 6 (Prohibited Conduct)

You must not:

Use the App for purposes that violate laws or public order and morals
Copy, modify, reverse engineer, or redistribute the App (except to the extent expressly permitted by law)
Interfere with the operation of the App

Article 7 (Disclaimer)

The App is provided "as is." The Operator does not warrant the accuracy, completeness, or fitness for a particular purpose of the App, or that it will be available without interruption.
To the extent permitted by law, the Operator is not liable for damages arising from your use of, or inability to use, the App — except in cases of the Operator's intentional misconduct or gross negligence.
Nothing in these Terms limits any rights you have under mandatory provisions of applicable law, including consumer protection laws.

Article 8 (Changes to and Termination of the Service)

The Operator may change, add to, suspend, or terminate the App without prior notice. Because the App does not depend on any external server, it may continue to work on devices where it is already installed even after distribution ends, but such operation is not guaranteed.

Article 9 (Changes to These Terms)

The Operator may amend these Terms as needed. For material changes, notice will be given by appropriate means such as an in-app notice, publication on this page, or update release notes. If you continue to use the App after a change, you are deemed to have agreed to the amended Terms.

Article 10 (Governing Law)

These Terms are governed by and construed in accordance with the laws of Japan. This Article does not deprive you of any consumer rights granted by mandatory provisions of the laws of the country or region where you reside.
