3. YouTube API Services and Data Collection

This app uses YouTube API Services. By using this app, you agree to the YouTube Terms of Service and Google Privacy Policy:

• YouTube Terms of Service: https://www.youtube.com/t/terms

8. Children's Privacy

Corodomo does not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete such information from our servers.

9. AI Processing of Your Data

To provide AI-powered features (such as pronunciation scoring, transcription, translation, furigana/pinyin generation, and AI-generated learning content), we send relevant inputs to the following third-party AI service providers for processing:

• OpenAI (Whisper): receives your voice recordings from pronunciation practice and the audio track of videos you upload, solely to convert speech to text for pronunciation scoring and subtitle generation.
• Soniox: receives your voice audio during AI speaking (roleplay) conversations, solely for real-time speech recognition.
• Google (Gemini): receives transcripts, subtitle text, and pronunciation scores (not your raw audio), solely to generate summaries, quizzes, translations, and learning feedback.

In the mobile app, we ask for your explicit consent before your data is sent to these providers for the first time; if you decline, the related feature is simply not used and no data is sent. These providers process such data solely to generate the requested output and under contractual terms that restrict their use of your data for other purposes, such as training their own models, except where you have explicitly opted in.

For YouTube videos, Corodomo does not download the video or its audio track. Only the publicly available subtitles/captions of the video you select are retrieved and processed by the AI providers above to create study materials.

We retain AI-generated outputs (e.g., transcripts, scores, generated content) as part of your account data to provide and improve the Services, in accordance with the data retention practices described elsewhere in this Policy. You may request deletion of this data by contacting us at contact@corodomo.com.

10. Changes to this Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page, and your continued use of the Services constitutes your acceptance of the updated policy.
