Does Tuta train on your data?
Tuta's privacy statement says the operating company has no access to the unencrypted data at all — a statement about what is reachable, not a promise about what it chooses to do.

How we read it: The sentence before the quoted one sets it up: "All user data is encrypted in a way that it is only accessible for the user and their communication partners." The policy never mentions training, machine learning or AI in any form — as with Signal, that silence is not what earns the grade; the incapacity is. One honest caveat the same document supplies: mail arriving from outside Tuta is not encrypted in transit, and "if unencrypted emails are sent or received by Tuta servers, they are encrypted for the user before they are stored" — so plaintext does cross their servers on the way in. Tuta does not claim to read it.

How to opt out of Tuta AI training
Plan by plan, from what Tuta'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.
All plans
There is nothing to opt out of. Tuta's own policy says it can't reach the content, so training on it isn't something a setting controls.
What this policy has done since we started watching
The record starts here. Tuta's policy was first captured on 5 Aug 2026, and there's no earlier copy to compare it against, so this verdict has no history behind it yet. From now on every re-read is diffed against that copy, and anything that moves appears here.
Everything we read
Vendor response
We wrote to Tuta on 27 Aug 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.

Tuta is graded A, and a company that's earned that can say so with the verdict itself. The image below links back to this page and shows the live grade. If the grade changes, the badge changes the same day, wherever it's embedded. It's free and it isn't for sale.
