Feature Requests + Bugs

Create an issue on Github for feature requests and bug reports.

Openly Operated

Lockdown achieves the highest level of transparency for both client and server via the Openly Operated standard. It has also been audited multiple times, the latest audit in July 2020. See the full reports here: Audit Kits


Pull requests are welcome - please document any changes and potential bugs.

Build Instructions

  1. pod install

  2. carthage update --no-use-binaries --platform iOS or for XCode 12 ./wcarthage update --no-use-binaries --platform iOS (workaround for this Carthage issue)

  3. Open LockdowniOS.xcworkspace

To sign the app for devices, you will need an Apple Developer account.

Limitations to Building Locally

If you build Lockdown locally, you will not be able to access Secure Tunnel, because that requires a Production app store receipt. We will soon enable a DEV environment for Secure Tunnel with limited capacity and regions, designed only for testing.

To use Secure Tunnel, you must download Lockdown from the App Store.
