Does Murf AI train on your data?
Murf sells synthetic voice. Its privacy policy uses the word "voice" zero times, and "AI" only inside its own web address.
This is the starkest absence in the batch. Murf generates and clones voices, and its privacy policy contains no form of "train", no "machine learning", no "artificial intelligence" and no "voice" at all. The five occurrences of "ai" are the letters in murf.ai. The document does describe what it holds — "Any photos, videos, audio or text content provided by you when creating Content" — and then says nothing about what is built from it. For a company whose product is a model of how a person sounds, the omission of the word for the thing being modelled is the finding.

How to opt out of Murf AI training
Plan by plan, from what Murf AI's own policy says about refusing. Where it publishes the steps, they're listed here with the limits they carry. Where there's nothing to switch off, or nothing graded, this says so instead of inventing a menu path.

Not graded, so no route is pointed at. This is the starkest absence in the batch.

What this policy has done since we started watching
The record starts here. Murf AI's 2 documents were first captured on 30 Aug 2026, and there's no earlier copy to compare them against, so this verdict has no history behind it yet. From now on every re-read is diffed against those copies, and anything that moves appears here.
