Proton Tuta
On what the policies say, Tuta is the better choice for your data: graded A against Proton's B.
Proton
Proton states that Proton Scribe does not use your data to train its models. The commitment is explicit and scoped to that one feature.
Verdict
B
- Does not train on you by default
- No opt-out in the policy
- Off by default. Training happens only if you opt in, or not at all.

Tuta
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.
Verdict
A
- Does not train on you by default
- Cannot train on you: the content is not readable to them
- Cannot train on you. Your content is not available to the company in usable form.
