Privacy Policy
In short
- You don’t need an account. We don’t ask for your name or email.
- The tools in the English version analyze your voice on your phone. That audio is not uploaded.
- Your practice history and saved recordings stay on your phone.
- We use Google services for analytics and ads, and RevenueCat to confirm purchases.
- We don’t sell your personal information and we don’t use your voice to identify you.
1. Who we are
Malhada (“the app”) is developed by Speechon Studio (registered business name: 스피치온스튜디오 / Speechonstudio), based in the Republic of Korea. In this policy, “we” and “us” mean Speechon Studio. If you have a question about your privacy, email malhada.app@gmail.com.
2. Your voice and recordings
Tools that stay on your phone
Shadowing, Pitch Check, Pitch Glide, Pitch Hold, Loudness Meter, Sustain Timer and Speech Pacer use your microphone to measure pitch, loudness and timing. This processing happens on your phone. Audio from these tools is not sent to us or to anyone else.
What is saved
Recordings and guide voices you choose to save, scripts you type, your practice history and your settings are stored on your phone. They remain there until you delete them or uninstall the app. We cannot see them and cannot recover them. To keep copies, use Export (available after you upgrade) to save them to your phone’s storage or another app.
Korean-language features
Some features are available only when the app is set to Korean on a Google Play account in Korea. Two of them send audio off the phone for speech recognition. These features are not available in the English version and are described in our Korean privacy policy.
No voice identification
We do not use your voice to identify you, and we do not create voiceprints.
Phone backup
If you have turned on Android backup, your phone may include the app’s data in your own Google account backup so it can be restored on a new phone. This backup is managed by Google under your account. We cannot access it.
3. Information collected automatically
| Service | What it receives | Why |
|---|---|---|
| Google Firebase Analytics | An app-instance identifier, your device’s advertising ID, device model, operating-system and app version, approximate country derived from your IP address, how often and how long you use the app, and which screens and tools you open. Measurement results (such as pitch, loudness or durations) and recordings are not sent. | To understand which tools are used and improve the app |

AdMob may show personalized ads based on your advertising ID. You can reset or delete your advertising ID, or turn off ad personalization, in your phone’s settings (usually Settings › Privacy › Ads or Settings › Google › Ads).
4. Purchases
Purchases are processed by Google Play. We do not receive your payment card details. RevenueCat verifies your purchase using an anonymous ID; it does not receive your name or email from us.
5. What we don’t do
- We don’t require an account or collect your name, email address or phone number. If you email us, we receive the information in your message.
- We don’t sell your personal information.
- We don’t use your voice to identify you.
6. How long information is kept
- Data on your phone: until you delete it or uninstall the app.
- Analytics data: up to 14 months, then deleted automatically.
- Purchase records: as long as needed to provide your purchase and to meet legal and tax obligations.
- Emails you send us: as long as needed to answer you.
7. Your choices and deleting your data
- Delete everything on your phone: in the app, go to Settings › Delete all data, or uninstall the app. If Android backup is on, also delete the app’s backup in your phone’s settings (usually Settings › Google › Backup) to remove every copy.
- Delete individual recordings: go to Settings › Saved recordings.
- Ads: reset or delete your advertising ID in your phone’s settings.
- Analytics and purchase records: email malhada.app@gmail.com. Because there are no accounts, we may ask for details such as the purchase date to find your records.
Depending on where you live, you may have the right to access, correct or delete your personal information, or to opt out of targeted advertising. To make a request, email us. We will not treat you differently for making a request.
8. Children
The app is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the app, email us and we will delete it.
9. International transfers
We are based in the Republic of Korea, and the services listed above may process information in other countries, including the United States. They process it under their own privacy and security commitments.
10. Changes to this policy
