Questions

Is there a length limit?

There's no fixed limit, but editing tools hold the decoded audio in memory — about 21 MB per minute of stereo sound (32-bit samples). An hour-long recording is fine on most computers; multi-hour files may be slow on phones.

Are my audio files uploaded anywhere?

No. Decoding, editing and encoding all happen inside your browser tab. Nothing is sent to a server, and closing the tab discards everything you haven't downloaded.
