I am looking at importing some audio and transcripts from other paid sites. Before I ask for permission from the creator, how secure is content marked “private”? Can other people still find it or will it be hidden from and inaccessible to all users? Also, aside from manually marking it as public, are there any circumstances where it would automatically become public? Finally, how does the LingQ company treat private content? Once uploaded is it considered property of LingQ and LingQ reserves the right to redistribute or does the user still have control over the files and text, specifically private files and text?
