This policy describes how the independent developer of the iOS app "PayCalc / 給料計算" (the "App"), as listed in the seller information on the App Store (the "Developer"), handles user information in the App.
1. No account required
The App does not require you to create an account or enter personal information such as your name, address, email address, or phone number.
2. Information we process and why
Work data you enter (shifts, working hours, hourly wages, salary records): used to provide the App's core salary-calculation features. Data is stored on your device, and may also be stored in the cloud (Google Firebase) linked to an anonymous identifier for backup and sync. The Developer cannot identify you personally from this identifier.
Usage data: to improve quality, we use Google Firebase (Google Analytics for Firebase) to collect statistics such as screen views, interaction events, approximate region, device model, OS version, and crash information.
Advertising: the App shows banner ads via Google AdMob to keep its free features available. In the course of ad serving, device information and IP address may be sent to Google. The App does not request App Tracking Transparency permission and does not perform cross-app tracking using the advertising identifier (IDFA).
Purchases: premium subscriptions are processed by Apple through the App Store. The Developer never has access to your payment details. Transaction information (purchase date, product ID, etc.) is used to verify your subscription status.
Support inquiries: when you contact support, we receive your email address and the content of your message, and use them only to respond.
3. Third-party services
