Asked, answered.

An umbrella for four focused consumer tools (Sino AI, Sino Tutor, Sino Learn and Sino Recipe) sharing one account, one design language and one set of standards. It is the consumer software division of Bonang Technologies.

Because a single app that does everything ends up doing none of it well. Each tool keeps its own front door and its own definition of done; what they share lives underneath.

The parent company. Bonang provides the engineering, infrastructure and long-term backing behind the Sino products.

No. One Sino account signs you into all four tools, and one subscription (Sino Plus) covers all of them. See the pricing page for the plan structure.

Yes, and it is deliberately useful rather than a locked demo: every tool is accessible free with sensible usage limits.

Sessions are priced by each tutor and paid per booking. Funds are held until the session is delivered; missed sessions are refunded under the marketplace policy.

Your account, preferences and the material you explicitly move between tools (say, notes into a tutoring session) carry across. Nothing is silently mined from one product to advertise in another. There are no ads at all.

Yes. Export and full account deletion are account-level actions that apply across all four products at once.

No. Your conversations and documents are used to serve you, not to build models on.

They roll out in stages. The roadmap page shows the honest current status of each product. Joining the waitlist gets you one email per launch, nothing else.

The tools are built connection-first and bandwidth-light, with early availability focused on markets where data is expensive. Regional pricing follows at launch.

Pick Sino Tutor as your interest on the contact form, or join the waitlist from the Sino Tutor page. Tutor onboarding opens before the learner marketplace does.
