Privacy Policy

My Language Coach ("we", "the app") is operated by Bruno Moïse as a personal project, currently in open beta.

What we collect

• Account data: email address (required for sign-in via Supabase).
• Practice activity: session start/end times, language practiced, duration, conversation transcripts.
• Voice audio: when you speak in the app, audio is transmitted to OpenAI for transcription. Audio is not retained on our servers after transcription.
• Device identifiers: a generated device ID stored locally on your device for cross-session continuity.

Third parties

• Supabase — authentication and database.
• OpenAI — voice transcription (Whisper) and conversational AI (GPT-4o).
• Google Cloud Text-to-Speech — generates the coach's spoken replies.
• Vercel Web Analytics — anonymous page-view counts on this website. No cookies, no personal data.

Data retention

Account data is retained until you delete your account from the app's profile screen. Practice activity is retained for as long as your account exists. Voice audio is processed in real time and not stored.

Your rights

You can delete your account at any time from the app. On request to the contact email below, we can also export or permanently delete your data.
