How we use the data

The article text is sent to Anthropic's Claude API solely for the purpose of generating the analysis you requested. The analysis is then returned to your browser and displayed in the side panel.

The local data stored on your device is used to provide the free tier, badges, and subscription functionality. This data never leaves your device.

Third-party services

NoiseFilter uses the following third-party services:
