Is Reminder | Refunder safe?

Low risk

Reminder | Refunder exposes its extension ID and version to every website it runs on.

The extension runs a content script on all websites and adds a hidden page element containing its runtime extension ID and version. Because that element is inserted into the page DOM, scripts from the visited site can read those attributes.
