NoiseLog Terms of Use

Effective date: August 2, 2026
Last updated: August 2, 2026

These Terms of Use (the "Terms") set out the conditions for using the iPhone app "NoiseLog" (the "App"), provided by Yuya Sato (the "Developer"). By downloading or using the App, you agree to these Terms.

The license for the App is governed by Apple's standard Licensed Application End User License Agreement (the "EULA"), and these Terms supplement it. If these Terms conflict with the EULA, the EULA prevails.

Article 1 (What the App Provides)

The App is a noise diary for your home. It provides: microphone recording (up to 10 minutes per recording), display of reference sound levels (dB) measured by your smartphone, saving, listing, playing back and deleting records, adding tags and notes, and creating PDF reports of your records.
Recorded audio and data are stored only on your iPhone. No account registration is required, and the Developer operates no server.
The App requires an iPhone running iOS 17 or later. Recording and viewing your records work offline; purchasing the paid feature and restoring purchases require an internet connection.

Article 2 (Fees, Purchases, and Refunds)

Recording, saving, listing, playing back and deleting records are free of charge.
PDF report export is a paid feature offered as a one-time purchase (a non-consumable in-app purchase). Once purchased, there is no further payment; there are no subscriptions and no automatic renewals. The App contains no advertising.
The price is as displayed in the App Store at the time of purchase and may vary by country, region, and time.
All payments are processed by Apple. Refund requests must be made to Apple, and Apple decides whether to grant a refund. The Developer cannot process refunds directly.
When you change devices or reinstall the App, you can restore your purchase via "Restore purchase" (available in the App's settings screen) while signed in with the same Apple Account used for the purchase.

Article 3 (Important Notes on Measurements and Reports)

The sound levels (dB) shown in the App are reference values measured by your iPhone's microphone, not measurements taken with a calibrated sound level meter. The Developer does not guarantee the accuracy of these values.
The Developer does not guarantee that the App's records or PDF reports will be accepted as evidence in negotiations, mediation, court, or any other proceedings, or that they will lead to any particular outcome, including resolution of a noise problem.
The App and its reports do not constitute legal, medical, or other professional advice. Please consult a professional where necessary.

Article 4 (Recording and Your Responsibility)

Recordings are made by your own action. Recorded audio may contain third parties' voices or other sounds. You are responsible for ensuring that making, keeping, and sharing recordings (including submitting PDF reports to others) complies with the laws applicable to you, including privacy and data protection laws.
The rights to the records you create with the App (audio, notes, tags, etc.) belong to you. This data is stored only on your device, and the Developer cannot obtain or view it.
Because your data is stored only on your device, it may be lost due to device failure or loss, iOS issues, or deletion of the App. Deleting the App erases all records and recordings, and they cannot be recovered. You are responsible for managing and backing up your data (for example, using iPhone backup features).

Article 5 (Prohibited Conduct)

You must not:

use the recording feature for eavesdropping or any other unlawful purpose, or for the purpose of infringing the rights of others (such as privacy or publicity rights);
copy, modify, reverse engineer, or redistribute the App beyond what the EULA permits; or
interfere with the provision of the App, or otherwise violate applicable laws or public order and morals.

Article 6 (Disclaimer)

The App is provided "as is." The Developer does not warrant that the App will be free of defects or interruptions.
To the extent permitted by law, the Developer is not liable for damages arising from your use of, or inability to use, the App (including data loss and lost profits). This does not apply where damages are caused by the Developer's willful misconduct or gross negligence. Nothing in these Terms limits any rights you have under mandatory consumer protection laws, including the Japanese Consumer Contract Act, that cannot be waived by agreement.
The App is provided by the Developer, not by Apple. Apple has no obligation to provide support for the App. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them directly against you.

Article 7 (Changes and Termination of the App, Changes to the Terms, Governing Law)

The Developer may change the App, add features, or discontinue the App. If the App is discontinued, the Developer will make reasonable efforts to provide advance notice.
The Developer may amend these Terms as needed. Amended Terms take effect when posted on this page or announced in the App. Material changes will be announced in a clearly noticeable manner.
These Terms are governed by the laws of Japan.
