Jeumero is a mobile game that helps you learn to understand and pronounce numbers in French. This policy explains what we collect and why.
You can start playing immediately as an anonymous guest. If you choose to save your progress, you can sign in with Apple or Google; we then store an account identifier so your streak, XP, and progress are preserved and can sync across devices. Authentication is handled by Supabase.
We store your answers, scores, streaks, levels, and which number patterns you find difficult, so the game can adapt and resurface them. This is tied to your account identifier.
In the “Speak” mode, we record a short audio clip of you saying a number and send it to a speech-to-text service (OpenAI) to check your pronunciation. Recordings may be kept for a few days so you can review them, then deleted. We do not use your voice for any other purpose.
Purchases are processed by Apple or Google and managed via RevenueCat; we receive your subscription status, not your payment details.
You can request deletion of your account and associated data at any time by contacting us. Pronunciation recordings are automatically removed after a few days.
