How do I get my wife on the bandwagon of self hosting and caring about their information and privacy?

Basically the title. I’ve set up Mealie, Plex (and Plexamp), a family planner (weekly meals, budget, calendar, etc.), and more. She discovered a fantastic family planning app that we started using yesterday. However, after reading about the data it collects, I was quite concerned. It gathers our addresses, emails, check-in notes, menstrual cycles, full calendar access, and more. I found a self-hosted alternative that looked very similar to the app she found, explained it to her, and demonstrated how it worked when I set it up. This led to a conversation that eventually turned into an argument about privacy and accessibility. I am very privacy-oriented, while she essentially says, “I don’t care about sharing personal details with company X; let them see when I have my menstrual cycle, etc.” She mentioned that the family planning app she found looked better and “warmer” and preferred it over the self-hosted one, even though they are essentially the same. To me, it’s baffling that she chooses minor UI details over our privacy. Any tips on how to persuade her to take her privacy more seriously? Is all hope lost?
