Privacy Policy

Last updated: 17 October 2026

This policy explains what information is collected when you visit xingyuzhitong.com and how it is used. The site does not have user accounts, sign-up forms or comment features.

Calculator inputs stay in your browser

All calculations run in JavaScript on your own device. The numbers you type into a calculator are not sent to our server, stored or logged by us.

Server and hosting logs

The site is served through Cloudflare. As with any website, Cloudflare processes technical request data such as your IP address, browser type and the page requested in order to deliver the page and protect the site from abuse. We do not use this data to identify visitors. Cloudflare's handling of this data is described in the Cloudflare Privacy Policy. We do not run our own analytics or tracking scripts.

Advertising and cookies

• This site shows ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info (and, in Europe, www.youronlinechoices.eu).
• How Google uses information from sites that use its services is explained at policies.google.com/technologies/partner-sites, and its advertising cookies at policies.google.com/technologies/ads.
• If you have opted out, you may still see ads, but they will not be personalised. Visitors in the European Economic Area, the UK and Switzerland may be shown a consent message managed by Google before personalised ads are used.

You can also block or delete cookies in your browser settings. Blocking cookies does not stop the calculators from working.

Children

The site is intended for a general and professional audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights and changes to this policy

Because we do not hold personal data beyond what our hosting and advertising providers process, requests about ad data are best made through the Google and Cloudflare links above. For questions about this policy, email huhuwen09@gmail.com. If this policy changes, the date at the top will be updated.
