I haven't heard of any translators leaking papers for the time being. The most important comparison database, which affects the duplicate checking of papers, was leaked in time and may not be in your duplicate checking database. I suggest you use Paperfree to check the copy of the paper, so don't worry about the leakage of the paper. These are all a bit unreliable. It is recommended to go to a regular translation company for translation. The primary goal is to ensure the confidentiality of customers. If the content is too private, the translation company will sign a confidentiality agreement for you to ensure that the document information will not be leaked.
