PRIVACY
Clear data use, without a hidden account.
What stays in your browser, what aggregate analytics measures, and when an audio recording leaves the device.
EFFECTIVE AUGUST 20, 2026
Most learning state stays in your browser.
Hanyu currently has no learner accounts or payment checkout. Progress, weak-item lists, preferences, and many practice results are saved with browser storage on the device you use.
Analytics helps count visits and understand which sections work. It is not used to build cross-site advertising profiles.
The browser asks for permission when you start a recording. Different recording tools handle audio differently, as explained below.
WHAT PRODUCTION ANALYTICS MEASURES
Usage signals, not the answers you type.
Hanyu's production analytics may process page paths, referrers, browser and operating-system type, device category, approximate country or region, visit timing, performance measurements, and selected product events such as starting a practice round or playing audio. Search terms, written answers, and recording contents are not intentionally attached to those analytics events. Network providers still receive an IP address to deliver a request and may retain access or security logs under their own policies.
HOW RECORDINGS ARE HANDLED
Local playback and optional assessment are different.
Speaking-paper and grammar recording tools create browser-session playback so you can listen to yourself; Hanyu does not intentionally upload those local playback recordings. If you choose automated pronunciation assessment, a short WAV recording, the reference Chinese text, and limited task context are sent to the Hanyu server and forwarded to the configured Tencent SOE-N pronunciation service for scoring. Hanyu processes that request transiently and does not intentionally save the audio as a user recording. The service provider may process technical request data under its own terms.
CHANGES AND SCOPE
This page describes the product that exists now.
If Hanyu later adds accounts, cloud sync, payments, advertising, or materially different data processing, this policy should be updated before those features are presented as available. External links and infrastructure providers have their own privacy terms.
