Why the DeepL API?

- Maximum data security: DeepL API Pro texts aren’t saved on persistent storage and aren’t used to train our models. And DeepL adheres strictly to EU data protection laws and ISO 27001. Learn more about data security at DeepL.
- Customization with glossaries: Specify your own translations for words and phrases, and customize your translations consistently and at scale.
