Which meditation journal apps have the best privacy?

Only StillMind and Day One offer end-to-end encryption where the company cannot read your entries. Insight Timer, Calm, and Sattva use standard cloud encryption where the company technically can access entries. For meditation journals containing highly personal thoughts, end-to-end encryption is strongly recommended. Additionally, StillMind and Day One offer local-first storage where your journal exists on-device even without internet.
