How to turn training off
- Buy DeepL Pro for anyone who translates work documents. DeepL says Pro texts are deleted after translation and not used to improve its service. Source: deepl.com
- Block or discourage the free DeepL translator for work, because DeepL may use free-version text to train its models. Source: deepl.com
- Save translations or glossaries only when needed. Saved items stay stored until you delete them. Source: support.deepl.com
Safer setup for a small team
Translate customer documents only with a paid DeepL Pro account, never the free translator, and save translations only when you need them.
Plan to approve: DeepL Pro
Setting to check: No free translator for work
A line for your AI policy: Staff translate customer or company documents only with our paid DeepL Pro account. The free DeepL translator is not used for work.
Want this in your team’s AI policy? The SafeStart kit, a plain-English AI policy and training for small teams, is coming soon.
