Privacy Policy
This policy explains what happens to information when you use WuAi Weather at www.5itq.com. In short: there are no accounts and no personal database, we do not ask for your name, phone or email, and advertising from Google sets cookies on the pages you visit.
Last updated: 17 October 2026
1. Information we collect
The city or district name you type, which is used to build the page you asked for. Standard server logs: requested URL, timestamp, HTTP status, referring site and a coarse region derived from the IP, used to keep the site running. Cookies: the site itself only sets functional cookies; advertising and measurement cookies are set by third parties as described below.
2. How we use it
For three purposes only: showing you the correct weather, keeping the site stable, and finding broken pages to fix. We do not sell, rent or trade personal information, and we do not build advertising profiles from your visits.
3. Google AdSense and advertising cookies
This site displays ads served by Google AdSense. Google and its partners use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet. You may opt out of personalised advertising by visiting Google Ads Settings at https://www.google.com/settings/ads . You can also opt out of third-party vendor cookies at https://www.aboutads.info/choices/ and https://www.networkadvertising.org/managing/opt_out.asp . Blocking cookies in your browser still lets you read the forecast, though some features may not work.
4. Weather data source
Live conditions, hourly and daily forecasts, air quality and living indices come from the public API of the China Meteorological Administration. These data contain no personal information; our role is display only.
5. What we do not do
No forced registration, no contact-book or precise-location permission requests, no selling of user data, and no sharing of identifiable information with third parties except where the law requires it or where it is needed to answer an email you sent us.
6. Retention
Server logs are kept for about 30 days for troubleshooting and then rolled off. Emails you send us are kept only as long as the conversation needs, and can be deleted on request. We keep no user database.
7. Children
The site is a general-purpose weather tool and is not directed at children under 13. We do not knowingly collect their personal information. If a parent believes a child has sent us information, write to the address below and we will verify and delete it.
8. GDPR and CCPA notes
For users in the EU or EEA, our lawful basis is legitimate interest in providing the forecast plus your consent for advertising cookies; you may request access, rectification or erasure, and you may complain to your local supervisory authority. For California users, under CCPA/CPRA we do not sell personal information and you may request disclosure, deletion and a copy.
9. Changes
If this policy changes in a material way we update the date above. Because we hold no personal data, we do not send separate change notices - please review this page from time to time.

Frequently asked questions
Common questions about our forecast data and about using this website.
Where does the forecast data come from?
Live conditions, hourly and daily forecasts, air quality and living indices are read from the public weather API of the China Meteorological Administration. WuAi Weather formats and displays that data; we do not run weather models.
How often is it updated?
Current and hourly data is normally refreshed about every 15 minutes, and the daily forecast once a day. If a number looks frozen, reload the page.
Why does some district say "live data unavailable"?
Usually one of three things: the upstream call timed out, the district was renamed or merged, or the province/city combination does not match the API exactly. Try the parent city, or search again with a different spelling and tell us by email.
How accurate is the 15-day forecast?
Short range is accurate, long range is a tendency. Use days 7 to 15 for the shape of the week rather than an exact figure and confirm close to your travel date.
Can I look up cities outside China?
Yes. There are pages for Hong Kong, Macau and Taiwan, and for major cities in Asia, Europe, North America, South America, Africa and Oceania.
Can I pull your data into my app?
No. This site is a display layer over a public API, so we do not offer a data feed or scraping licence. For commercial weather data go to the meteorological service or a licensed provider.
Is the site free? Do I need an account?
Everything is free, with no registration and no marketing email. Advertising through Google AdSense pays for the server and the domain.
What personal data do you collect?
We do not ask for your name, phone or email. Your search term is used to build the page you requested, and Google sets cookies for ads on its own terms, as described in the privacy policy.
Are sunrise and sunset in local time?
Yes, they are shown in the local time zone of that city, with no conversion to Beijing time.
How do I report a wrong reading?
Email the address in the footer with the city, the period that looks wrong and the page URL. We compare it against the official bulletin and correct the display; warnings and emergencies always follow the official service.
