What: TrackDons is a simple tool to help you keep track of the projects you donate to. It will help you remember which projects you have donated to and when (and if you should donate again), and it encourages you to make your donations public as a way of inspiring your friends to donate to the same project or others in need.
TrackDons is live at https://trackdons.org
It's an open source project: https://github.com/TrackDons
It was launched in 2016 but with hardly any followup, the activity in anecdotal.
