group.com.readdle.shared
group.com.readdle.shared is a shared data folder used by Readdle apps on Mac to store content and settings they access together.
What is group.com.readdle.shared?
group.com.readdle.shared is a Group Containers folder in your Mac user Library that is used by Readdle apps to share data with each other. Group Containers let related apps from the same developer read common files, account details, synced content, and app support data without duplicating everything in each app’s own container. In everyday use, this kind of folder can support workflows across Readdle products such as document handling, syncing, and shared settings. Users usually encounter it while checking storage use, cleaning leftover app data, or removing apps they no longer use. Because it belongs to app data rather than macOS itself, its importance depends on whether you still use Readdle software on this Mac.

Safety overview
Status: Mostly safe
This is ordinary app data created for Readdle software, not a macOS system component. Deleting it is generally safe only if you no longer use the related Readdle apps, but doing so can remove shared documents, synced working data, saved state, or settings those apps rely on. If you still use Readdle apps, leave this folder in place to avoid losing shared data or breaking app features until the apps recreate it.
Recommendation: Keep this folder if you currently use Readdle apps on your Mac. If you have already uninstalled all related Readdle software and do not need any remaining shared data, you can remove it as part of cleanup, preferably after checking whether it contains files you want to keep.
