Social Amnesia aims to make your social media (twitter/reddit) only exist within a time period that you choose. For many people, there is no reason they want to have years old tweets or reddit comments publicly accessible. With Social Amnesia, set the time period you want to keep, whitelist posts and items you want to preserve indefinitely, and let Social Amnesia wipe the rest out of existence.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
