Is Cookie AutoDelete safe?

Automatically clears cookies and other site data after tabs are closed, with whitelist and greylist controls.

This extension deletes site data such as cookies, IndexedDB, local storage, and cache for sites after their tabs are closed when auto-clean is enabled. You can keep data for selected sites using a whitelist permanently or a greylist until browser restart, and you can also clear site data manually from the popup. It supports exporting and importing whitelist and greylist settings.
