External Services

This plugin optionally connects to one of three external translation APIs depending on which provider you choose in Settings → AutoLingo. No data is ever sent without an explicit translation action and a valid API key that you supply yourself.

DeepL

What it is: DeepL is a machine translation service. This plugin uses the DeepL REST API to translate your post content.

What data is sent: The text content of your posts (title, body, excerpt) is sent to DeepL’s servers for translation. If you use the Glossary feature, your glossary terms (source and target words) are also sent to create a DeepL glossary. No personally identifiable information about your site visitors is transmitted.

When it is sent: Only when a translation is triggered — either manually via the Translate button, automatically on publish (if enabled in settings), via WP-CLI, or when syncing a glossary.

Service endpoint: api.deepl.com (Pro) or api-free.deepl.com (Free plan)

OpenAI

What it is: OpenAI provides the GPT language model API. This plugin uses the gpt-4o-mini model to translate your post content when OpenAI is selected as the provider.

When it is sent: Only when a translation is triggered manually or on publish.
