No, it is not. We recommend our users use a safe download manager for Social Media downloads such as SocialDownloadManager. The Social Download Manager is available for Windows and Mac and has been in development since 2011 to ensure that all data and information exchanged between your computer and internet servers stays encrypted and secured in an end-to-end process.
This naturally includes the downloader itself, the website link you are downloading from along with any social media content or sensitive information that may be downloaded during the process.
