Calm vs Headspace

Neither policy says whether your data trains AI models. Both are UNCLEAR, and the search terms tried are on each entry.

Grades read the plan most people are on. Each company's full entry has every plan, every clause and the archived copy it was read from.

Calm

Calm holds what you use to sleep and what you tell it about your mood. Its privacy policy does not mention AI, machine learning or training anywhere.

Verdict

By default: The policy does not say
The way out: Nothing to opt out of on the record
Last checked: 1 Sept 2026

Headspace

Headspace lists powering machine-learning algorithms among the uses of your personal information. Whether your data trains them, it never says.
