+Forget is a post deleting service for Twitter, Mastodon, and Misskey.
 
+You can run a copy of it on your server, or use the server run by the
+maintainer at <https://forget.codl.fr/>

+
+## Features
+
+  * Delete your posts when they cross an age threshold.
+  * Or keep your post count in check, deleting old posts when you go over.
+  * Preserve old posts that matter by giving them a favourite or a reaction.
+  * Set it and <i>forget</i> it. Forget works continuously in the background.
+
+## Non-features
+
+Forget is not a one-time purging tool. It is designed to prune your account
+continuously, not quickly. If you need a lot of posts gone fast, you may want
+to look for another more-suited tool.
