Adeona is an Open Source system for tracking the location of a lost or stolen laptop that does not rely on a proprietary, central service. This means that you can install Adeona on your laptop and go — there's no need to rely on a single third party. What's more, Adeona is privacy-preserving. This means that no one besides the owner (or an agent of the owner's choosing) can use Adeona to track a laptop.
