Terms of Use

Guitar Fretting · Day Important

Effective and updated: October 22, 2026

Service and agreement

Day Important provides Guitar Fretting (吉他按弦) for touchscreen guitar fingering and rhythm practice. Please read these terms before use. The iOS app is also licensed under Apple’s Standard End User License Agreement (EULA). This page supplements service and membership details and does not replace that license or your statutory rights.

Trial and features

A continuous 72-hour free trial starts at first launch, including time spent closed or in the background. This is a local app trial: its expiry alone does not trigger a charge. Practice features require active membership after the trial; basic settings and the standalone metronome remain available. Features depend on the current version.

Subscriptions, one-time purchase and renewal

Available options may include monthly and yearly subscriptions and a one-time lifetime purchase. Available products, local prices, currency, periods and purchase confirmation are shown by the App Store. Monthly and yearly subscriptions renew automatically unless cancelled under store rules; renewal may be charged within 24 hours before the next period starts. Cancel at least 24 hours in advance. Lifetime membership is a non-consumable one-time purchase with no automatic renewal, providing permanent membership entitlement in the current app; it is not a promise that the app or platform will operate forever. Eligibility and renewal terms for Apple offers appear at redemption or confirmation.

Management, restoration and refunds

Manage or cancel subscriptions in Apple account subscription settings. Deleting the app does not cancel a subscription. Use Restore Purchases in the membership screen to restore eligible purchases under the same Apple account. Offline access relies on cached entitlements; renewal and refund changes require a successful store connection to update. Request refunds through Apple’s refund process, subject to Apple’s decisions and applicable law.

Acceptable use and intellectual property

Follow applicable law. Do not unlawfully copy or distribute the app or its content, interfere with the store or purchase verification, or infringe third-party rights. App code, interface and built-in practice content are protected by intellectual property laws. Uses expressly permitted by the license or applicable law remain permitted.

Practice and service limitations

The app is a practice aid and does not guarantee learning outcomes. Screen measurements depend on device information and calibration and may differ from a real guitar. Take reasonable breaks and stop if you experience discomfort. System, store or network issues may interrupt service; we will reasonably maintain the app. Liability limitations permitted by applicable law follow Apple’s Standard EULA. Nothing here excludes non-waivable consumer rights or liabilities.

Privacy, changes and contact

See our Privacy Policy for information handling. We may update these terms as features or store rules change and revise the date here, providing legally required notice of material changes without reducing purchased entitlements or mandatory legal rights.
