If you use the free DeepL translator or app, the text you submit for translation may be used by DeepL to train its AI and may be reviewed by DeepL staff or contractors. This does not apply to paid or API users.
Free-tier users' translation inputs, including potentially sensitive personal or professional content, may be accessed by DeepL employees or third parties and incorporated into AI training datasets; the only way to prevent this is to upgrade to a paid plan.
