Baby Buddy maintainer here — I have often thought about trying to turn the app in to a product for non-techie parents and still respect user privacy but I feel like that is still a hard sell (i.e., I don’t think I’d get far just being more privacy focused than other options out there). Also the options have actually improved a pretty good deal since the time I started working on this for our family (from a usability, if not privacy POV).
Thanks, by the way, for contributing! We have long passed our own need for the app with our little ones but it has been a joy to maintain and interact with Baby Buddy’s users over the years.
