Privacy Policy

Last updated: May 22, 2026

Sifter does not collect, transmit, or store any of your data. Period.

Data Collection

Sifter collects no data of any kind. The application:

• Makes no network connections
• Does not communicate with any server
• Does not include analytics, telemetry, or crash reporting frameworks
• Does not include third-party SDKs of any kind
• Does not require an account or registration

File Processing

All file processing occurs entirely on your device. Files you drop into Sifter are:

• Read from your local filesystem
• Processed in-memory using Sifter's own C metadata engine
• Written back to your local filesystem (in-place or as a new file)
• Never transmitted, uploaded, or copied off your device

Data Storage

Sifter persists only a single user preference (whether to dismiss the overwrite warning), stored locally via Apple's UserDefaults on your device. No application state or file information is stored between sessions.

Third-Party Services

Sifter uses no third-party services, APIs, SDKs, or external code. All dependencies are statically linked from vendored source and included in the application binary.

Apple App Store

Sifter uses no App Store-provided analytics (no StoreKit, no AdServices, no AppTrackingTransparency). Apple may collect standard anonymized usage statistics through the Mac App Store as described in Apple's own privacy policy. This is outside Sifter's control and is consistent with every Mac App Store application.

Your Consent

By using Sifter, you consent to this privacy policy.

Changes to This Policy

If this policy changes, the "Last updated" date at the top will be revised. No material change will involve data collection, because the application is physically incapable of making network connections.
