Privact - Client

The client-side daemon for Privact.

It has two functionalities:

1. Continuously gathering personal data (at first only system health data).
2. Responding to federated surveys (polled from ../server).

Status

Heavily work in progress, the current goal is to get it to a proof of concept stage.

Development

Requirements

For the moment, you'll need to manually install a few dependencies:

1. A C++ toolchain (e.g. GCC, LLVM or MSVC) - note that at the time of writing, you will have to use Clang for the linting to work (see below).
2. CMake
3. The Qt framework, version 6.2.4 (or later, presumably)
4. GPGME
5. Qt Designer
6. clang-format and clang-tidy, version 14 (later versions format code differently, unfortunately)
7. botan

Debian/Ubuntu

sudo apt install build-essential clang cmake qt6-base-dev clang-format clang-tidy designer-qt6
echo 'export CXX=/usr/bin/clang++' >> ~/.profile
. ~/.profile

Building

make

Running the tests

make && make test

Linting

We use linting to improve maintainability and to reduce nit picking, please run it before committing any changes:

make lint

To comply with the formatting rules, run:

make format

Running the daemon

make run-daemon

There are a few environment variables you can set to configure the daemon:

• PRIVACT_CLIENT_SERVER_URL - point to the base URL of the server, without trailing slash, e.g. http://localhost:8000.
• PRIVACT_CLIENT_ENABLE_E2E - set to 1 to enable experimental end to end encryption.

Running the UI

make run-ui

Submitting data

The daemon receives data from suppliers via D-Bus. See example_supplier for an example supplier you can use to submit arbitrary data.
