Audio processing
The BPM & Key Finder and LUFS Meter read your selected file using your browser’s audio APIs. Analysis runs in a local web worker. These tools do not upload your audio to ToolYogi or send it to an analysis service. The file name and results are displayed in the current page and are not saved by these tools.

The Stem Separator and Vocal Remover decode audio and run AI source separation in your browser. The selected audio and generated stems are not uploaded to or stored on ToolYogi servers, and this tool does not create a cloud history. Temporary browser-memory references are discarded when the page is refreshed or closed. The AI model and runtime are separate static resources that your browser downloads to perform local processing.

Image processing
The Image Compressor decodes and re-encodes supported images using browser image and Canvas APIs. The selected image is processed locally and is not uploaded to ToolYogi for compression.
Website requests
Opening this website still requests pages, scripts and assets from its hosting provider. Local file processing does not make your visit anonymous. Hosting infrastructure may process connection information such as IP addresses and request logs; its retention settings are separate from the files processed locally by these tools.
Accounts, analytics and advertising
ToolYogi currently has no user accounts. Google Analytics 4 may be enabled when a measurement ID is configured for the deployed site. When enabled, Google Analytics can receive website interaction and device or connection information used for aggregate traffic measurement; it does not receive the audio or image files processed locally by ToolYogi tools. Advertising scripts are not enabled in this version. This notice should be reviewed again before advertising, consent tooling or other third-party tracking services are added.
Future tools
Different tools may have different processing needs. Any future tool that sends a file to a server should explain that behavior before you use it.
