Request permanent deletion of your ScreenTasker family account and all associated data. Have your Family ID? It speeds up review, but it's not required - the Google Play account email below is enough on its own.
Still have the app installed? It's faster to request deletion directly in ScreenTasker, under Settings → Family Account → Delete Family Account. The in-app request is actioned automatically; a request submitted through this page is manually reviewed and takes longer (see below).
Using this page is never required - a family account with no device sync activity for 30 days is automatically deleted on its own. This page only exists to let you request deletion sooner, if you'd rather not wait.
