Privacy policy

01　Scope and contact

This policy covers the Strumnote iPhone app and support email. For privacy questions or requests, contact the Strumnote operator at eunjongpark2@naver.com.

02　Songs, recordings and settings

Songs, chord fingerings, strumming patterns, comments, recordings, app settings and tutorial progress are stored on your device. The app does not automatically send this data to a developer-operated server. Strumnote does not require an app account and does not use advertising or behavioral analytics SDKs.

03　Microphone access

The microphone is used when you start a recording, and recordings are saved on your device. You can change microphone permission at any time in iPhone Settings. Other features remain available without microphone permission.

04　Apple payments and purchase restoration

Apple’s App Store processes Pro purchases and purchase restoration. The app checks purchase information supplied by Apple to determine your Pro entitlement. The developer does not receive your card number or Apple Account password. Apple’s privacy policy applies to information processed by Apple.

05　Backups and shared files

You start backups manually and choose where to save them. The app does not automatically sync between devices. If you choose an external storage service such as iCloud Drive, that service processes the file. PDF, audio and video exports are sent only to the apps or services you choose for sharing. Those services’ own privacy policies apply.

06　Support email

When you email us, we use your sender address, message and any attachments you choose to provide to investigate and respond. Support emails are received and stored through NAVER Mail. Please do not send sensitive information that is unnecessary for support, such as passwords or card details.

We keep support information for as long as needed to handle the inquiry and delete it when that purpose is fulfilled, unless applicable law requires retention. We do not use it for advertising or marketing.

07　Visits to this support website

This support website is hosted on Google Sites. The operator has not added advertising or visitor analytics tools to this website. The hosting service may process technical information such as IP addresses and browser details to deliver and secure the pages. Your songs and recordings are not sent to this website.

08　Deletion and privacy requests

You can delete device-stored content in the app. Deleting the app may remove its local data, so back up anything you want to keep first. Backup and export files saved elsewhere or shared with another service must be deleted separately at that location.

To request access, correction or deletion of information you sent to support, contact the email address above. The developer cannot remotely view or recover data stored only on your device.

09　Changes to this policy

We will update this page and its effective date when app features or information handling change.
