ShareX is a free Windows program for capturing the screen, recording it and sharing files. You take screenshots or screen recordings, edit them and send them to one of the supported upload services. It installs as an ordinary desktop application and is aimed at individual users and teams who often need to capture and share what is on screen.
ShareX is free software under the GPL (version 3) and is maintained by the ShareX Team; no company or foundation is named. The public profile of the lead developer lists Turkey; the co-founder lists Australia. According to its privacy policy, the application itself collects no data. It does check GitHub for updates at start-up and periodically afterwards. Files go only to services you choose and configure yourself, so you decide where your data ends up. The source code is hosted on GitHub and open to inspection.
