Privacy Policy

Last Updated: 2025

1. Local-First Philosophy

PDF Mail Engine is designed as a "Local-First" application. This means that your data never leaves your device during the normal operation of the software. We do not upload your PDFs, Excel lists, or email credentials to any cloud server.

2. Data Collection

We do not collect any personal data from the application usage. All processing (PDF generation, email sending) happens locally on your machine.

Microsoft Store: When you download the app from the Microsoft Store, Microsoft collects basic telemetry (install counts, crash reports) subject to their privacy policy.

3. Email Credentials

Your SMTP credentials (if used) are stored securely on your local machine using the operating system's credential manager. We never access or transmit these credentials.

4. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
