Privacy Policy / 隐私政策

VulpFlow ("the App") is developed by Yufan Shi ("we", "us", or "our"). This Privacy Policy explains how we handle information when you use our App.

Data Storage

All data you enter in the App — including account balances, income, expenses, and financial settings — is stored locally on your device only. We do not collect, transmit, or store any of your personal or financial data on external servers.

Data We Do Not Collect

We do not collect:

• Personal identification information
• Financial data or account information
• Location data
• Device identifiers
• Usage analytics or crash reports

Notifications

If you enable notifications, the App schedules local notifications on your device to alert you about balance warnings and upcoming expenses. These notifications are processed entirely on your device and no data is sent to any server.

Third-Party Services

The App does not integrate any third-party analytics, advertising, or tracking services.

Data Backup

If you use the export backup feature, a JSON file containing your financial data is saved to your device or shared via apps you choose (e.g., email, AirDrop). We have no access to this data.

Children's Privacy

The App is not directed at children under 13. We do not knowingly collect any information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Continued use of the App after changes constitutes acceptance of the new policy.
