1. Data we collect
Depending on how you use ShuoBa, we may collect account details, sign-in identifiers, lesson progress, speaking recordings, replay videos, subscription status, device diagnostics, and support messages. For shadowing practice, we also process audio files or media links you choose to import, the resulting transcripts and translations, and your feature usage counters (used to apply plan limits).
2. How data is used
We use personal data to authenticate users, sync progress across devices, evaluate speaking practice, restore purchases, respond to support requests, maintain service security, and improve reliability.
3. Permissions and on-device data
The iOS app requests microphone access for speaking practice, camera access for optional replay recording, speech recognition access for faster and more accurate scoring, and photo library access only when you choose to import a video into shadowing practice. The app stores some cached lesson data and downloaded shadowing audio locally to improve loading speed and offline playback.
4. Third-party processors
ShuoBa uses service providers that support hosting, authentication, file storage, purchase verification, and AI-assisted speaking evaluation. These providers may process data on our behalf only to operate the service.
For AI features, third-party providers may include OpenAI, DeepSeek, and Google Cloud TTS.
Data shared with AI providers may include user-entered AI chat text, speech transcript text, expected/reference sentence needed for scoring, selected response language, audio you import into shadowing practice (for speech-to-text transcription and translation), short pronunciation recordings made in shadowing practice (for AI feedback), and limited technical metadata required for request routing, abuse prevention, and service reliability.
ShuoBa asks for in-app user consent before enabling AI features that transmit personal data to third-party AI providers. If a user declines, those AI features remain disabled until consent is granted.
5. Data retention and security
We retain account and learning records only as long as reasonably necessary to provide the service, resolve disputes, comply with legal obligations, and protect against abuse. We apply reasonable safeguards, but no online system can guarantee absolute security.
6. Your choices and contact
You may contact us to ask for account help, data correction, or deletion at shuoba.app@gmail.com or via Zalo 0927639219. We may update this policy when the product or legal requirements change.
