Why I built this

My stack grew, and I couldn't find a tracker that was private, honest, and actually built for this. So I built one.

I'm not a company. I'm a fellow stacker who wanted a better way to keep track of what I've worked for — encrypted, on my own device, where only I can read it.

A passion project by a stacker, for a stacker.

Your stack deserves this

Your metals are real.
Your tracker should be too.

Take back your privacy and track your stack properly.
