This Privacy Policy explains how PSA鑑定プラン最適化 (PSA Plan Optimizer) handles user information.
本プライバシーポリシーは、PSA鑑定プラン最適化（以下「本アプリ」）におけるユーザー情報の取扱いについて説明します。

1. Information We Handle / 取り扱う情報

The app may process the following user-input values for calculation purposes:

Purchase price / 購入価格
PSA10 price / PSA10価格
PSA9 price / PSA9価格
Estimated PSA10 probability / 想定PSA10確率
Selling fee rate / 販売手数料
Miscellaneous costs / 諸費用
Days until sale/payment / 売却・入金までの日数
Plan settings (fee, lead time, etc.) / 各プランの料金・納期などの設定値

These values are used only to provide calculation results inside the app.
これらの値は、アプリ内で計算結果を表示する目的でのみ利用されます。

2. Storage and Purpose / 保存場所と利用目的

Data entered in the app is stored locally on the user’s device (e.g., app settings).
The data is used only for:
- Profit/ROI calculation
- Keeping user settings
- Improving usability (reducing repeated input)

本アプリで入力・設定された情報は、主に端末内で保存・利用され、上記目的以外では使用しません。

The app does not send user input data to the developer’s server.
The app does not provide user data to third parties, except when required by law.

本アプリは、法令に基づく場合を除き、ユーザー情報を第三者に提供しません。

4. Analytics, Ads, and Tracking / 解析・広告・トラッキング

No in-app advertising is currently used.
No user tracking mechanism is currently used.
No external analytics SDK is currently used.

現時点で、広告配信・トラッキング・外部解析SDKは利用していません。
将来これらを導入する場合は、本ポリシーを更新します。

5. Data Retention and Deletion / 保持期間と削除

Locally stored app data may remain until the app is deleted or app/device data is reset.
Users can remove stored data by deleting the app or resetting app data on the device.

6. Children’s Privacy / 未成年者の利用

The app is not specifically directed to children, but may be used by a broad audience.
If required, minors should use the app with guardian consent.

7. Security / セキュリティ

The app is designed to minimize unnecessary data transmission by primarily using local storage.
However, complete security cannot be guaranteed due to platform/device constraints.

8. Changes to This Policy / ポリシーの変更

This Privacy Policy may be updated due to legal, functional, or operational changes.
Any important updates will be reflected on this page with the revised date.
