Data Safety
Last Updated: April 5, 2026
1. We Value Your Privacy
XinChao is built privacy-first: strict safeguards, secure cloud infrastructure where a feature needs it, and minimal data collection. We don't sell your practice sessions or location history to third-party advertisers.
2. Information Collection
We collect minimal data to improve the app—like which survival phrases are used most often or if a lesson screen crashes. This data is anonymized and never linked to your personal identity.
3. Microphone & speech
We need microphone access for speaking practice and speech recognition feedback. Audio is captured on your device; to return coaching or scores, audio or derived text may be sent over encrypted connections to our backend or vetted AI providers. We don't use that content to profile you for ads, and we don't sell it.
4. Third-Party Services
We use payment processors like RevenueCat and Google/Apple Pay for the survival kit. They handle your payment data securely; we never see your credit card number.
5. Your Choices
You can delete your account and all associated data at any time via the internal settings. If you delete it, it's gone for good—just like that one Bánh Mì stall that disappeared overnight.
