We value your privacy and will never sell, rent, or lease your personal information. In our paid tools, we do not link any of the content you read to your account. In this beta tool, we do retain a copy of uploaded PDFs for internal troubleshooting purposes, so we can improve the PDF conversion process. For this reason, you should not upload any PDFs that are confidential. Rest assured that once we release this tool out of beta, we will no longer retain copies of PDFs, in keeping with our generally-applicable privacy policy. If you have any questions, feel free to shoot us an email!
