The Open Source Dog Barking Detector is a completely offline, browser-based application that processes all audio data locally on your device. We are committed to protecting your privacy and ensuring that no personal data is collected, stored, or transmitted.
This tool uses machine learning (specifically the YAMNet audio classification model via TensorFlow.js) to analyze audio input from your microphone in real-time. All processing happens entirely within your web browser - no audio data, recordings, or analysis results are ever sent to external servers.
We do not collect, store, or transmit any personal data.
Audio is captured temporarily in your browser's memory for real-time analysis. The audio data is processed in 1-second chunks and immediately discarded after classification. No audio is stored on your device beyond the temporary buffer required for processing.
The external resources loaded are:
While TensorFlow.js is loaded from a CDN, all audio processing and machine learning inference happens locally in your browser. No audio data is transmitted to external servers.
The app uses Cloudflare R2 to host exported logs temporarily for sharing. Files uploaded there are public to anyone with the link. Users should avoid including sensitive or personal data in shared logs.
This website uses Cloudflare for basic web analytics. Cloudflare may collect anonymous information about your visit, such as:

Since all processing happens locally in your browser, your audio data never leaves your device. The security of your data depends on your browser's security and your device's security measures.
