Privacy Policy

Effective date: August 26, 2025

Mouth Breathing Notifier (“the App”) helps you detect sustained mouth breathing using your computer's webcam. We designed it to be privacy-friendly: detection runs locally in your browser; video is not uploaded to our servers.

What the App does

  • Uses your webcam via the browser's getUserMedia permission.
  • Runs facial landmark detection in-browser (WebAssembly). No raw video frames are transmitted to us.
  • Optionally shows on-page alerts and browser notifications when your threshold is reached.

Information we collect

  • Web server logs (standard): IP address, user-agent, timestamps, requested paths. Used for security and operations.
  • Local storage (on your device): preferences like threshold, seconds, color, and consent state. You can clear these anytime in your browser.
  • Advertising: We use Google AdSense, which may set cookies and collect usage data to serve and measure ads. See “Advertising & cookies.”
  • Metrics (optional, self-hosted): We may collect aggregate operational metrics (e.g., request counts) on our server. No face data or video leaves your device.

Advertising & cookies

We use Google AdSense to display ads. Google (and its partners) may use cookies and similar technologies to serve personalized or non-personalized ads and measure performance. You can control consent via the banner on our site and your ad settings in your browser.

Consent controls

You'll see a consent banner on first visit. You can change your choice anytime by clearing site data or using the “Privacy settings” link (if present). When consent is denied, ads may operate in limited mode or be disabled depending on your region.

Data retention

  • Web server logs: retained for a limited period (e.g., 30-90 days) for security/operations, then deleted or aggregated. Exact period may vary by deployment.
  • Local storage on your device persists until you clear site data or change settings.

Children's privacy

The App is not intended for children under 13. If you believe a child has provided us information, contact us and we'll address it.

Security

We use HTTPS and standard security controls. As with any web app, avoid using the App on untrusted devices or networks.

Your rights

Depending on your location, you may have rights to access, correct, or delete personal information and to object to or restrict certain processing. Contact us to exercise these rights.
