Release note: Before store submission, confirm that inquiries sent to the contact address below can actually be received and handled.

1. Basic Policy

The App is an accountless, offline-first practice logging tool. Practice data is generally stored on the user's device and is not automatically sent to a server operated by the developer.

2. Information Stored by the App

The App may store the following information on the user's device to provide its features:

This information is used to display practice history, calculate last results, personal bests, and target lines, and maintain app settings.

3. Automatic Transmission to the Developer

The App does not currently include:

If the user voluntarily contacts the developer by email, form, store review, GitHub Issues, or another channel, the inquiry content, reply address, device information, app version, and related information may be handled for support purposes.

4. Purchase Information

If the App provides Pro features in the future, purchases will be processed through Apple App Store or Google Play. The App does not obtain payment card numbers or similar payment credentials.

Purchase verification, restoration, and refunds are handled according to the mechanisms and terms of the applicable app store. The App may store purchase status provided by the app store on the device to enable or restore Pro features.

6. Sharing of Information

The App does not automatically share locally stored practice data with the developer or third parties. However, information may be handled as necessary in the following cases:

7. Data Retention and Deletion

Practice data stored on the device remains there until the user deletes it. The user can delete practice sessions, target results, round results, and current session draft data through the "Delete all data" feature in the App.

Data may also be deleted if the App is uninstalled, the device is reset, or the operating system removes app data. Information managed by app stores, such as purchase status, may be retained or restored according to the relevant app store mechanisms.

Support-related information may be retained for as long as reasonably necessary to respond to inquiries, improve quality, and comply with legal obligations.

8. Security

The App stores practice data on the user's device. Data leakage, loss, or corruption may occur due to device loss, theft, failure, operating system behavior, other apps, or backup settings. Users are responsible for managing device locks, OS updates, and backups appropriately.

9. Children's Privacy

The App is not designed as a service primarily directed to children. Minors should use the App with the consent and supervision of a parent or guardian.

10. Changes to This Policy

This Privacy Policy may be updated due to feature changes, legal changes, or store requirement changes. When important changes are made, the developer will provide notice in the App or on the public web page by an appropriate method.
