Terms of use
By using the Aethopia website and app you agree to these terms.
Last updated: 2026-11-05
Not an official warning service
Aethopia presents public meteorological data and adds its own estimates (for example signal probabilities and storm track projections). Those estimates are research in nature and may be wrong or late. For any decision affecting safety, property or travel, rely on the official warnings of the Hong Kong and local meteorological authorities.
Data sources and attribution
Data comes from official meteorological agencies in Hong Kong and overseas and from other public sources. Each source's name and licence, the disclaimer text we are required to display, and the items Aethopia computes itself are listed on the Sources and limits page. The Government and relevant organisations own the intellectual property rights in their open data; Aethopia has no co-operation with or affiliation to any data source.
Availability and liability
The website and app are provided as is, without warranty that data is accurate, complete or uninterrupted; when an upstream source is down the page says “unavailable” rather than filling in numbers. To the extent permitted by law, Aethopia is not liable for any loss arising from use of, or inability to use, the service.
Acceptable use
You may view and share Aethopia content for personal and commercial purposes provided attribution is kept; you may not bulk-scrape the data endpoints or redistribute data under Aethopia’s name. The Aethopia name, mark and self-computed content are protected by copyright and trade mark law.
Privacy
How data is handled is described in the Privacy policy.
Governing law
These terms are governed by the laws of the Hong Kong Special Administrative Region. Changes are dated on this page.
