Privacy Policy

Secure File Eraser ("the App") respects your privacy and takes the utmost care in protecting your personal information. This Privacy Policy ("Policy") explains how we handle information in connection with the App.

1. Our Commitment

The App is built on a privacy-first design principle. All file erasure operations are performed locally on your device. File contents are never transmitted to external servers.

2. Information We Collect

2.1 Information We Do NOT Collect

The App does not collect the following information:

• Contents of files being erased
• File names or file paths
• Personally identifiable information (name, email address, phone number, etc.)
• Location data
• Contact information

2.2 Information We May Collect

To improve app quality, we may collect the following anonymized information:

• Crash reports: Technical information when the app crashes (stack traces, device model, OS version). No personally identifiable information is included.
• Usage statistics: Anonymized data about app usage frequency and feature utilization.

3. How We Use Information

Collected information is used solely for the following purposes:

• Fixing bugs and improving app quality
• Enhancing user experience
• Informing feature development decisions

4. Sharing with Third Parties

We do not share your information with third parties except in the following circumstances:

• When required by law
• When necessary to protect the life, body, or property of an individual, and obtaining your consent is difficult
• When particularly necessary for improving public health or promoting the sound development of children
• When cooperating with government agencies or local authorities in executing legally mandated duties

In addition, user information may be shared with the following third parties for advertising purposes:

• Google LLC (AdMob advertising platform)
• Advertising partners (advertisers participating in the Google advertising network)

5. Data Security

The App's file erasure process implements the following security measures:

• Overwriting all file data with zeros (0x00)
• Overwriting all file data with ones (0xFF)
• Overwriting all file data with cryptographically secure random data (SecRandomCopyBytes)
• Deleting the file after overwrite completion

This 3-pass overwrite method makes recovery of erased files technically extremely difficult.

The App may use the following third-party services. Please refer to each service's website for their respective privacy policies.

• Apple App Store / Google Play Store: App distribution platforms
• Google AdMob: Advertising service (Privacy Policy)

• Device information (OS, device model, screen size, etc.)
• Advertising identifiers (IDFA/AAID)
• IP address (used to estimate approximate location)
• App usage data (ad impressions, clicks, etc.)
