What OpenFlat is
OpenFlat is online teaching software for individual teachers holding one-to-one, small-group, or larger classes. Its live classroom supports low-latency audio and video, a collaborative whiteboard, hand raising, student participation, chat, and screen sharing. Teachers can share PPTs, documents, audio, and video, with PPT animations preserved. Classroom plugins can add quizzes, check-ins, timers, scoring, or third-party applications, and classes can be recorded for later playback. It is listed for Android, iOS, macOS, web, and Windows. Plans range from CN¥25 a month for 体验版 to CN¥280 a month for 高级版; the one-time 畅享版 is CN¥6,000, paid once and valid for one year. Plans differ in credits, room limits, participant caps, and storage. A credit is deducted when at least two people stay in a room for 10 minutes; solo teacher preparation is free for up to 60 minutes. Each class includes 10 minutes for students to join and five minutes of overrun time. A full refund may be requested within seven days if no valid credits were used; used service is not refundable. Crucially, the service agreement describes OpenFlat as a test product for GPP customers, provided as-is, and says users should not reasonably expect privacy or security during the test period.
