"We process the content you upload and their translations or improvements for a limited period of time to train and improve our neural networks and algorithms. This also applies to corrections you make to our translation or improvement suggestions." (q1, section 3). In addition: personal data in the free service "may be checked by a human" (q1, only in the note on the Korean version, section 24.2).

q1 section 13 refers, for "DeepL API Free", to the terms and conditions and to "section 3 on using the free version of DeepL" (section 3 describes use for training, see the Free plan). It contains no express statement on training specifically for API Free. Developer documentation q8: "With DeepL API paid plans, texts aren't saved on persistent storage and aren't used to train our models"; this expressly applies only to paid plans. The pricing page (q10, API tab) lists the free API plan "Developer" (one-off credit of 1 million characters) and names "no use of your data for model training" (translated) only for the Growth plan ("all the benefits of Developer, plus:", translated); whether Developer is identical to API Free is not stated there.
