FAQ

Frequently asked questions about Dimension Space (次元空間) — features, privacy, pricing, and who it's for.

What is Dimension Space?

Dimension Space (次元空間) is an AI study app for Hong Kong DSE and junior-secondary students, developed by Flyer Group Limited (Starcloud Tutoring). It is available on the App Store for iPhone and iPad, covers a range of DSE and junior-secondary subjects, and focuses on AI snap-and-ask help, knowledge-tree progress, a built-in dictionary, and HK-style Traditional Chinese explanations.

Does it just give answers and encourage copying?

No. The AI snap-and-ask uses a three-layer hint chain — first a hint, then the thinking approach, and only at the end the answer — so students are encouraged to reason it out themselves rather than copy.

Is my data safe? Where is it stored?

Content data is stored on Hong Kong endpoints; photos stay on your device by default and are only uploaded when you explicitly tap "Ask AI". We never use your content to train AI models.

Is it free? Is there a trial?

A free trial is available, followed by an optional monthly or annual subscription. There is no gacha, no infinite scroll, and no manipulative monetisation.

Which devices are supported?

iPhone and iPad, available on the App Store. An Android version is planned.

Which subjects are covered?

A range of DSE and junior-secondary subjects — Chinese, English, Math (incl. M1/M2), Physics, Chemistry, Biology, History, Geography, Economics and more, with ongoing expansion.

How is it different from Photomath or Question.AI?

Dimension Space does more than hand over answers — it guides thinking with a three-layer hint chain, uses HK-style Cantonese-inflected Chinese, links every question back to the knowledge tree, and offers character-driven story problems built for Hong Kong students.

Does it promise better grades?

No. We do not promise grades or university admission; it is positioned as a study-support tool.
