StemStudio ("the Service") is a web application that separates audio inside your browser. This privacy policy describes how privacy is handled when you use the Service.
The Service never sends the audio you provide to any server. All processing happens in your browser, and your audio is never exposed externally. The separated results (WAV files) are also generated in-browser and saved locally only when you explicitly choose to download them.
The Service may use your browser’s localStorage to remember your preferences (such as light/dark theme). This does not collect any personally identifiable information.
The Service may use advertising services such as Google AdSense. Ads may be shown based on your browsing history via cookies. This does not collect personally identifiable information. For details on ad delivery, please see: Google Privacy Policy
The Service may use analytics tools such as Google Analytics. These may collect statistical information about how the site is used, but no personally identifiable information is collected.
The Service may link to external websites. Please review the privacy policies of those sites individually. We are not responsible for the content or privacy practices of external sites.
This privacy policy may change without prior notice as the Service improves or as laws change. The revised policy takes effect once posted on the Service.
You are responsible for using the Service only with audio you own the rights to, or are permitted to use. You are responsible for complying with applicable laws and treaties regarding the separation and redistribution of copyrighted audio.
