I agree, I wish they took privacy more seriously, as more software should.

Looking at it optimistically, they don't sell or share with data brokers/advertisers, you can block the offensive connections with a firewall, and the app doesn't ask for any information that is particularly sensitive.

Additionally, they use data people choose to share to improve the scientific understanding of meditation and mindfulness. I am someone that values privacy, but I don't find it egregious to use this app.
