SILENT OS
A foundation built on privacy
Silent OS is an Android-based operating system, enhanced to address mobile privacy concerns facing enterprises today. Free of bloatware, hooks to carriers, and leaky data, Silent OS puts privacy in the hands of you and your enterprise, without compromising productivity.
Spaces
Spaces creates multiple, separate virtual phones on one device, enabling work life and personal life to stay securely compartmentalized. No data is shared between spaces.
- Create up to four separate spaces that act like virtual phones
- Keep your apps and data secure
- Customize each space any way you like


Security Center
At the heart of Silent OS, Security Center puts privacy settings at the user’s fingertips.
- Easily configure settings for individual spaces
- Manage which apps live in each space
- Fine tune individual app permissions so that the user decides the level of data access each app receives
Apps designed with privacy in mind
Blackphone comes preloaded with our own apps as well as third party apps that enable private, encrypted communication.
