Practice data stays local
Your songbook, lyrics, annotations, and settings are stored in this browser. Local audio and video files are stored in this browser's IndexedDB and are not uploaded to axjin. Clearing browser data can remove local data.
External services
The songbook loads thumbnails for your YouTube links from YouTube, and the practice desk uses YouTube's embedded player. Loading thumbnails or loading or playing a video connects your browser to YouTube or Google, which may receive device, network, and playback information under their own terms and privacy policy. Local files and private lyrics are not sent with thumbnail requests. YouTube Terms · Google Privacy
