getPitch does not collect, transmit, or share any personal data. All audio analysis is performed locally in your browser using the Web Audio API.

Audio from the active YouTube tab — analysed in real-time in the browser. No audio data is stored or transmitted anywhere.
Tab URL and title — used solely to verify you are on a YouTube watch page and to display the song title in the popup. This data is never stored or sent off-device.
chrome.storage.session — stores temporary analysis results (detected key, highest note, BPM) for the current browser session only. This data is erased automatically when the browser closes.
chrome.storage.local — stores a single user preference: the transpose slider position (a number from −3 to +3). This value never leaves your device and contains no personal information.

getPitch does not use analytics, advertising, or any third-party services. It makes no network requests.

activeTab — to access the audio element on the current YouTube tab.
storage — to pass analysis results between the content script and popup using session storage.
tabs — to read the tab URL and title.
*://*.youtube.com/* — content script is limited to YouTube only.
