I have to agree. Privacy is a right. It's not often you run into a free alternative that offer sync capabilities across all platforms and devices. You also have a way to restrict or remove access from unknown fingerprints. The only downside I see about Wire is that the option to "submit crash reports and usage data" is enabled by default but that's just an Advanced options visit away from disabling. Give Wire a try and give their white papers covering how they approach [1] privacy and [2] security a read.
