Privacy Policy

Last updated: 2026.

What we collect

An account holds your email and the conversations, saved words, pronunciation attempts, and progress you create while learning. When you speak in the app, we process the resulting audio recording to turn it into text. Payment details are handled entirely by the payment provider — the App Store or Google Play for an in-app subscription, or Stripe on the web; we never see your card number.

How we use it

Your messages and recordings are used to teach you — to generate the tutor’s replies, translate between languages, transcribe your speech, give feedback, read text aloud, and score your pronunciation. We do not sell your personal data.

AI services we share data with

mon-omon relies on third-party artificial-intelligence services to provide its features. To deliver them, we send the text you write and the audio you record to these providers, and show you what they return:

  • OpenAI — generates the tutor’s replies, translates between languages, transcribes your speech to text, produces feedback, and reads text aloud. See OpenAI’s privacy policy at openai.com/policies/privacy-policy.
  • Microsoft Azure (Azure AI Speech) — scores your pronunciation when you use the pronunciation feature. See Microsoft’s privacy statement at privacy.microsoft.com/privacystatement.

These providers process the data solely to deliver the requested feature and under contractual terms that require protection at least equivalent to our own. The app asks for your agreement before sending any of your data to these services, and you can withdraw that agreement by deleting your account. We do not send your data to any AI service for advertising, and we do not use it to build an advertising profile of you.

Your choices

You can delete your account and all of its data at any time from within the app (Account settings), or by emailing [email protected]. Deleting your account permanently removes your email, conversations, recordings’ transcripts, saved words, pronunciation scores, and progress.
