How we process data

Online classroom

To keep the online classroom smooth and reliable, class audio and video is de-identified and processed in Singapore.

Online classroom audio and video is relayed and processed by NetEase Yunxin in its Singapore data centre. Yunxin only receives a random number made for each class, never your account, name or contact details. Recordings are moved to the region that holds the class and then deleted from Yunxin.

Content safety

To keep classes safe and improve our service, some data is de-identified and processed in mainland China.

Audio from open classes and the text you post in the community is checked for safety by NetEase Yidun in mainland China. Only the content is sent, without your account or name. The result is only used to decide whether the content can be shown publicly.

Maps

Maps are provided by Baidu. Loading a map sends your IP address to Baidu.

Maps are provided by Baidu Maps. When you open a page with a map, your device loads it directly from Baidu, so Baidu receives your IP address and general information about your device. If you don't agree, maps are not loaded and addresses are shown as text.

Web search

When the AI assistant searches the web, the search words go to a search service in China.

The web search is provided by DeepSeek (China). Outside the Beijing region only the search words the assistant writes are sent — never your own words, your IP address or your account; in the Beijing region your question is also sent, to rank the results. Personal details you put in a question can end up in the search words, so it’s best to leave them out.

You are not asked about this one separately: it only happens when you ask the AI assistant to search the web, so if you'd rather not send anything, don't ask it to.

Institutions' heads and administrators

An institution's head and administrators may be in another region.

An institution's data is kept in its region. Its head and administrators may have accounts in other regions: when they open the institution workbench, their region passes their requests on to the institution's region, and on pages such as orders, finance, bookings, trial lessons and recruitment they see your name, notes and résumé — nothing of it is stored in their region. Each such read is recorded in both regions' cross-border logs. When you order, book, sign up or apply, you can see which institution it is.

Operations staff

Operations staff may be in other regions; IPs and accounts are masked by default when they look at running logs.

To keep the service running, ops admins can see each region’s running state, alerts and recent running logs, and they may be in other regions. What they see is returned live by your region and shown to them only, not kept in other regions; IP addresses in logs show only their first part and accounts are replaced by pseudonyms. When the original of one entry is really needed, they must give a reason, can see one entry at a time, and it is audited. Every look from another region is recorded in the cross-border logs of both regions.

Feedback

Your feedback is handled by CLEC staff, who may be in another country or region.

What you write in Feedback and ideas, your screenshots and the details sent along (version, system, language, the page) are kept in your account’s region. To handle it, CLEC staff (who may be in Beijing, China, or another region) look at it live over an encrypted channel between regions. Nothing is copied to other regions, and they cannot see your phone number or email; each look from another region is recorded in both regions’ cross-border logs. Your consent is recorded when you send it. To-dos made for developers leave out your account, name and your own words. When you delete your account, your feedback and screenshots are deleted with it.
