SERVICE INFORMATION
AI & your data
A clear look at what is processed when Coro helps you practice. AI feedback is learning guidance, not a certified language assessment.
Updated November 9, 2026
What is sent for processing
A submitted speaking exercise can include your audio, reference passage and selected language. Feedback can use pronunciation measurements, transcript or timing information, previous exercise results and the learning preferences needed for that task.
Messages you send to the coach and goal text you enter may be used to personalize responses. Do not put passwords, payment information, confidential work content or other people’s private information into learning content.
Which services can be involved
Google Gemini: language understanding, lesson generation, coaching feedback and speech-assessment fallback. The configured gateway can use Groq and DeepSeek / OpenRouter as alternatives for text processing.
Microsoft Azure Speech and iFLYTEK ISE: speech / pronunciation assessment, depending on language and availability.
ElevenLabs and Microsoft Azure: reference text-to-speech audio. The reference passage is processed to create a voice for you to practice with. These are AI / speech processors, not human teachers.
Your permission
Before submitting a learner recording to AI processing, the app presents a consent prompt. Choosing not to consent stops that recording flow. Microphone permission is a separate system permission; giving microphone access is not the same as consenting to AI processing.
To stop future processing, do not submit new content. Disable microphone access in device settings if desired. Contact [email protected] to withdraw consent or ask about deleting submitted data.
Limitations and retention
Background noise, accent, pacing and recording quality can affect feedback. A score is a practice signal; it is not a promise of proficiency, an exam result or an evaluation of you as a person.
Your learning history and feedback can be retained in your account. Provider-side retention depends on the configured service and applicable agreement. This page does not promise zero retention or that every provider uses identical data practices. See the privacy policy and contact support for details.
