English 30 is built offline-first. We do not operate user accounts, track personal identities, or store voice recordings on cloud servers. Your speech and learning progress remain 100% on your device.
This Privacy Policy explains how English 30: Speak in 30 Days ("we", "our", or "the Application") handles user information when you install and use our mobile application. We are deeply committed to protecting your personal privacy and providing a secure, offline-first educational platform.
By downloading or using English 30, you consent to the information practices described in this document.
English 30 is designed from the ground up as a standalone, offline-first application:
To deliver real-time interactive language learning, the Application requests specific permissions strictly for on-device features:
| Permission | Purpose | Data Retention |
|---|---|---|
| Powers real-time speech recognition and AI pronunciation feedback during speaking practice exercises. | Ephemeral in RAM only. Audio is processed instantaneously in device memory and is never recorded to disk or uploaded to any cloud server. | |
| Sends scheduled local daily reminders to help you maintain your 40-minute daily learning habit and streak. | Scheduled locally on your device hardware; no remote push server is involved. | |
| Detects external wireless headsets or microphones so you can practice speaking hands-free. | No hardware telemetry is tracked or stored. | |
| Used solely for standard platform library initialization and optional native Text-To-Speech engine voice assets. | No personal browsing or user data is transmitted. |
Our intelligent AI tutor ("Maya") and speech evaluation modules utilize on-device machine learning inference (LiteRT-LM / compatible speech models). When you speak into the microphone:
English 30 is designed for general audiences aged 13 and older seeking to improve their spoken English skills. We do not knowingly solicit or collect personal identifiable information from children under the age of 13. Because all data is stored offline on the local device, parental guardians retain complete physical control over the device and can delete all local data at any time.
You have full ownership of your data at all times:
Because your data resides exclusively within Android's sandboxed local application storage, your information is protected by your device's operating system security (such as biometric lock, pin, and disk-level hardware encryption).
We may periodically update our Privacy Policy to reflect app enhancements or legal guidelines. Any modifications will be posted directly within this document along with an updated effective date.
