MacPaw is a Ukrainian software developer known primarily for its CleanMyMacX and SetApp applications. In addition, the team has developed a new app called SpyBuster. SpyBuster is a Mac-only application that allows users to determine if any applications on their computers are of Russian (or Belarussian) origin or if their data is stored on Russian servers.

Knowing about data stored in Russia is important since Russian authorities can compel local companies to hand over all data (voice calls, data, metadata, etc.) created or stored on Russian servers for the last six months. Metadata must be stored for three years.

SpyBuster can also act as an active firewall blocking all communications with Russian and Belarussian servers.

The scans are performed locally, and the data does not appear to be shared with MacPaw.

SpyBuster is a free software application.
