An open alternative to Facebook will be launched on 15 September, the developers of the project have said.
Diaspora describes itself as a “privacy-aware, personally-controlled” social network.
The open-source project made headlines earlier this year when Facebook was forced to simplify its privacy settings, after they were criticised for being overly complex and confusing.
The project, developed by four US students, raised $200,000 (£140,000).
