Does Manus train on your data?
Manus's policy now says de-identified data made from your personal information may be used "to develop and improve our models", with an opt-out by email in some places. Manus is being written to.
This clause is real, but it doesn't resolve the training question - see the finding below.
"We may make personal information into de-identified and/or anonymized data by removing information that makes the data identifiable to you. We may use such data to analyze, improve, develop and protect the Service, including to develop and improve our models and related technologies."

Why this is still UNCLEAR: Manus's privacy policy, revised 28 September 2026, now answers part of the question. Personal information turned into "de-identified and/or anonymized" data may be used "to analyze, improve, develop and protect the Service, including to develop and improve our models and related technologies". The same paragraph adds: "Depending on your jurisdiction, you may opt out by contacting us at the email address provided below." Which jurisdictions, it doesn't say. The deletion section mentions content that's been de-identified "when you allow us to use your content to improve our models". That reads like a setting, and the policy doesn't name it or say which way it ships. Prompts still go to third-party AI providers, who "may infer information about you". The entry stays UNCLEAR while Manus is asked about the setting, because this site writes to a company before it publishes an adverse finding about it.

How to opt out of Manus AI training
Plan by plan, from what Manus'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.

Vendor response
We wrote to Manus on 11 Sept 2026, quoting the clauses above and inviting a correction. Nothing has come back. That's published because a company declining to comment on its own policy is something a reader should know, and because the invitation should be on the record whether or not it's taken up. Any reply goes here, word for word.
