ShadowSeal Privacy Policy

Last Updated: August 1, 2026

Thank you for using ShadowSeal (the "App"). We take your privacy and the protection of your personal information seriously. This Privacy Policy explains how we collect, use, and protect your information.

1. Information Collection

This App does not collect, upload, or store any of your personal data.

Specifically:

• No Personal Information Collected: The App does not require account registration and does not ask for any personally identifiable information such as your name, email address, or phone number.
• No File Uploads: The images and PDF files you watermark are processed entirely on your device. No files are ever uploaded to any server.
• No Analytics: The App does not integrate any third-party analytics or tracking SDKs, and does not track your usage behavior.
• No Advertising: The App does not include any advertising services and does not collect data for ad targeting purposes.

2. System Permissions

The App may request the following system permissions for specific features:

• Photo Library Access (iOS): Required only when you choose to save watermarked images to your photo library. This permission is used solely for writing images and does not read your existing photos. You can revoke this permission at any time in your device settings.
• File Access: Required to read the image or PDF files you select, and to save watermarked files to your chosen location. All file operations are performed locally on your device.

3. Data Security

Since all data is processed locally on your device and never transmitted over the network, your watermark content and file content remain entirely under your control. We recommend protecting your device using the security features provided by your operating system, such as a passcode, Face ID, or Touch ID.

4. Children's Privacy

The App does not knowingly collect any personal information from children. If you are a parent or guardian and believe your child has provided personal information through the App, please contact us so we can promptly delete the relevant data.

5. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this Privacy Policy periodically to stay informed.
