Tracking emotional experience

Hello does anyone know a tool which I can track my mood.
At the moment I am using T2 Mood Tracker I aseptically like the way you can add your own rating scale.

But I don’t want to use all scales, and I prefer to host the data on my own server for privacy and security reasons.

Maybe someone knows a open-source solution that I can host on my own server (PHP and MySQL server) or a app that encrypted and can only read by me.

Best regards,
