Guitar Fretting · Day Important

Effective and updated: October 22, 2026

Scope and operator

This policy explains how Day Important (“we”) handles information in Guitar Fretting (吉他按弦). Contact us at doneandnext@outlook.com.

Information on your device

The app stores preferences locally, including language, metronome, display, calibration and recent selections, together with the first-launch time, trial timing reference and cached membership entitlements. These support saved settings, trial timing and access decisions. Completed steps, missed steps and active duration are used for the current practice session; a history of practice results is not currently saved.

Purchases and payments

Purchases and payments are handled by the Apple App Store. The app reads products, verified transaction results, subscription expiry and revocation status to grant, restore and refresh access; membership type and subscription expiry are cached locally. We do not receive your full payment card details. Apple processes account, payment and transaction information under its own policies.

The current app requires no app account, does not record microphone audio, does not display advertising or perform behavioral analytics, and does not track you across apps for advertising. It has no feature that uploads app preferences or practice statistics to our own servers. We do not sell personal information. Purchases interact with Apple store services. Third-party processing is governed by the relevant provider’s policies, linked below.

Retention, deletion and choices

Local settings and membership caches remain until overwritten, cleared or the app is removed; device backups may retain copies. Removing the app does not cancel a subscription or delete Apple’s transaction records. Manage subscriptions through your Apple account. We retain information you email us only as needed to respond and resolve the request, unless law requires longer retention. You may email requests to access, correct or delete relevant information; we respond within applicable legal requirements and time limits. We cannot directly access preferences stored only on your device.

Children and security

The app is not intended to collect children’s personal information. Minors should use the app and make purchases with guardian guidance. Contact us if you believe a child has sent us personal information by email. We use safeguards appropriate to the information, but cannot guarantee absolute security of storage or transmission.

Updates and contact

We update this page and its revision date when features or information practices change, and provide any notice required by law for material changes. For questions, contact Day Important at doneandnext@outlook.com.
