Yes! Filerev takes the security of your files seriously. We use the latest and best security practices. We also regularly submit the app to a security audit by a neutral third party, which verifies that we are following the industry standards as defined by OWASP Application Security Verification Standard (ASVS) and further requirements as defined by Cloud Application Security Assessment (CASA). This audit is also provided to Google for review.
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 with security practices such as encryption at rest, in-transit encryption, and user isolation, to name a few.
