Privacy and security

Processing runs in your browser. The selected video file stays in page memory while this tool is open and is not uploaded by CrateX.app. The output format may stay in browser storage or sync as a low-risk setting if WebDAV sync is enabled. Source videos and extracted audio results are not synced by default. On shared devices, clear the tool, downloaded files, and site data when needed.
