Open your notes and write three lines: (1) your org-approved translation path (or 'unknown — ask IT') (2) one text type that's allowed in a public translator (3) one text type that must never go there. You're done when you've rewritten one public-safe sentence with a translator (or skipped it if policy forbids) and confirmed you used no client data or PII.

Public translators are not a secure vault for client text
Free public translation tools are fine for public-safe wording — never paste client names, contracts, or credentials; use org-approved translate when the content is work-sensitive.
Worked example
Just translate this' is pure muscle memory: drop a paragraph into a free site and ship it. That text might end up training a model or logging outside your tenant. It comes down to tool choice again: public translators are fine for public-safe copy only. For contracts, HR, or customer data, use the approved org tool (or a human translator) and keep human review before send. The outbound message is still yours to own.
