Information We Collect
We collect information you provide directly to us, including:
- Account information (email, name) if you sign in with Google or Apple. A guest account needs no email or name.
- Learning progress, XP points, and streak data
- Voice recordings when you practice pronunciation. These are sent to our AI processors, named under AI Services below, to transcribe and score what you said. We do not store them on our servers.
- Messages you write to Ellie, the in-app AI coach. These are sent to OpenAI to generate her reply. Your chat history is kept on your own device, not on our servers.
- A few short notes Ellie keeps about you, for example a sound you find hard or why you are learning, so she can remember you between chats. OpenAI writes them from your recent messages. We store them with your account on our servers, and they are deleted when you delete your account.
- App preferences such as voice settings
- Support messages when you contact us through the in-app chat or bug report feature
- Device notification tokens for delivering push notifications and practice reminders
How We Use Your Information
- To provide and maintain the app
- To save your learning progress across devices
- To score your pronunciation and generate your coach's replies, using the AI processors named under AI Services below
- To improve our lessons and teaching methods using aggregated, non-identifying usage data. We do not use your voice recordings or your chat messages to train any AI model, and neither do our processors.
- To send you notifications about your learning streak (if enabled)
- To respond to your support requests and bug reports
- To send you practice reminders and important updates (if enabled)
Data Storage
Your data is stored securely using Google Firebase services. We use industry-standard encryption to protect your information.
Data Sharing
We do not sell your personal information. We may share data with:
- Google Cloud and Firebase for authentication, data storage, and hosting our backend services
- OpenAI for speech-to-text transcription, text-to-speech audio, and the AI conversation coach
- Microsoft Azure Speech for pronunciation scoring and analysis
- RevenueCat for in-app purchase processing and entitlement management
- Firebase Analytics and Crashlytics to understand app usage and fix crashes. Analytics is linked to a random account ID, not your email or name. Crash reports are not linked to your account. You can turn both off in Settings.
- Vercel Analytics and Speed Insights on our website, hinglish-vinglish.com (anonymized, no cookies)
AI Services
Parts of the app cannot work without sending your data to an AI service run by another company. This section says exactly what is sent, who receives it, and what they do with it.
Before any of this happens, the app shows you a disclosure screen naming this data and these companies, and asks you to agree. Nothing described here is sent until you do. You can review or withdraw that permission at any time in the app under Settings, and the features that depend on it will stop sending data.
| What is sent | How it is collected | Who receives it | What it is used for |
|---|---|---|---|
| Your voice recording | From your device microphone, when you tap the record button to practice a word or phrase | OpenAI, L.L.C. (United States) and Microsoft Corporation, via Azure AI Speech (United States) | To transcribe what you said and score your pronunciation, and return that score to you |
| The messages you write to your coach | From the in-app chat, when you send a message | OpenAI, L.L.C. (United States) | To generate the coach's reply |
| Your recent messages to your coach | From the in-app chat, every few messages | OpenAI, L.L.C. (United States) | To write a few short notes about what helps you learn. We keep the notes with your account so the coach remembers you |
| Your first name and learning profile: chapter progress, streak, words you have mastered and words you find hard | Generated by your use of the app, and sent alongside a chat message | OpenAI, L.L.C. (United States) | To let the coach teach at your level and refer to what you have already learnt |
| Lesson text (not your personal data) | From our own lesson content | OpenAI, L.L.C. (United States) | To produce the spoken audio you hear in lessons |
Protection by our processors. We send this data under each provider's commercial API terms and data processing addendum, which bind them to protections equivalent to those in this policy. Under those terms:
- They process the data only to return our result, and act on our instructions as processors, not for their own purposes.
- They do not use your data to train or improve their models.
- They do not sell it or share it with anyone else.
- They apply encryption in transit and at rest, and delete transient request data on their standard retention schedule (up to 30 days for abuse monitoring at OpenAI, then deleted).
We do not send your email address, your account identifier from Google or Apple, your payment details, or your support messages to any AI service.
Purchase Data
When you make a purchase, we receive purchase and entitlement events from Apple or Google Play (via RevenueCat) and store them in our database to:
- Verify your access to paid content, including Lifetime Access, pronunciation credit packs, and any chapters bought under our previous per-chapter pricing
- Provide customer support if you contact us about a purchase
- Maintain an audit trail of purchases and refunds
- Track renewals and expirations for the small group of users still on a legacy subscription
We do NOT receive or store your payment card details. All payments are processed by Apple on iOS, or by Google Play on Android, under the account you are signed in to on that store.

International Data Transfers
Your data is stored on servers in the United States via Google Cloud/Firebase. If you are located outside the US, your data will be transferred internationally. We protect your data using industry-standard security measures and contractual safeguards.

App Tracking & Analytics
On iOS devices, we respect Apple's App Tracking Transparency framework. We will request your permission before tracking your activity across other companies' apps and websites. You can change your tracking preferences at any time in your device Settings under Privacy > Tracking.
We use analytics to understand how people use the app and to improve the lessons. Analytics data is linked to a random account ID, never your email or name. We do not collect your device's advertising ID. You can turn analytics and crash reports off at any time in the app under Settings, Usage and crash data.
Children's Privacy
Our app is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at support@keedastudios.com and we will delete it.
Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy in the app and updating the "Last updated" date. Your continued use of the app after changes constitutes acceptance of the updated policy.
