Privacy Policy

Account data: your email address and a securely hashed password.

Learning data: your placement results, per-skill CEFR levels, study plan, attempts, scores, flashcard review history, and progress.

Audio: if you use speaking or pronunciation features, we may process and (with your consent) store audio recordings together with their scores.

Usage data: feature usage counts used to enforce free-tier limits and improve the product.

To provide and personalize your learning experience, including generating your study plan and adapting to weak areas.

To produce AI feedback and scoring on your writing and speaking.

To operate billing and enforce free-tier limits.

To maintain the security and integrity of the service.

Some features send your submissions (for example writing text or speaking transcripts) to AI providers to generate feedback. We send only what is needed and validate all responses before showing them to you.

AI-generated levels, scores, and feedback are estimates intended to guide your learning. They are mapped to the CEFR framework but are not official certifications or guarantees of exam performance.

You can request deletion of your account, learning data, and any stored audio at any time from Settings or by emailing support@lumiere.example.

When you delete your account we remove your personal data, audio recordings, and learning history except where we must retain limited records to meet legal or billing obligations.

We use third-party processors for AI feedback, speech/pronunciation assessment, payments, and hosting. Each processes data only to provide their service to us.
