Yes! Filerev takes the security of your files seriously. The software has gone through multiple audits with Google to be listed in the Google Play Store and the Google Workspace Marketplace.
The software also retrieves a minimal amount of data from your Google Drive account, which primarily consists of file metadata. This data is stored on secure servers using the latest security practices, such as encryption at rest, in-transit encryption, and user isolation, to name a few.
We also have written guarantees in our privacy policy and terms in regard to how your data is handled.
Still want to know more? You can read reviews about the Clean Drive app on the Google Workspace Marketplace and on the Google Play Store. Chrome Unboxed also wrote a nice article about us a couple of years ago (back when we were named Clean Drive).
