The log generally does not contain any personal information, we automatically censor your signing private key.
If you're concerned about the contents of the file, press 'e' and hit enter and you can view/edit the file.
Once you've finished censoring out any information you don't want to share, just save and close the file, and we'll ask you if you're ready to upload yet
Otherwise, just type 'y' to upload the file, or 'n' to quit without uploading the file. You can access the log file at $LOG after closing.
