giggi.me tries to protect users privacy while they interact with the website. It runs open source software, check the bottom of this page for links.
It doesn't store cookies on the client side. All information associated with the user session are kept on the server and destroyed periodically once the user has left the website.
Nonetheless, there are other agents that could, to some extent, track users using giggi.me. For instance, programs running on the client end especially if the user comes from a mobile device.
giggi.me is hosted by digitalocean, which can in theory run programs server side to monitor and track the user. In addition, there are other third party watchers that can generally monitor the traffic transiting in and out giggi.me.
All traffic generated is encrypted, which doesn't mean it is really secure, but it's better than plain text.
On the server, the user interacts with Apache, Mysql and CodeIgniter.
On the client end there is minimal code that giggi.me runs and it all comes from Pelican.
