Privacy Policy

Using the tools

China Converters does not require an account, checkout or user profile. Size measurements, pasted size-chart text, birthday inputs and assumed shopping amounts are processed by the browser's tool code. They are not included in the site's custom tool-event payloads. Currency tools request selected currency codes and dates or date ranges from the Frankfurter API; a reference-rate request does not need your shopping amount or assumed fee. The calendar library is served from this site's assets.

Saved-tool preferences use browser storage on your device. You can clear that storage through your browser settings. Calendar and CSV downloads create local files; sharing or importing those files is a separate action you control. Avoid putting private details into a public page URL or a correction report.

Hosting and technical requests

Cloudflare provides hosting and delivery. Network services receive technical information associated with a request, which can include IP address, browser information, requested URL and time. That processing is separate from the calculator arithmetic. Read Cloudflare's privacy policy for its practices.

Analytics

The site loads an Ahrefs Web Analytics script to understand page use. Loading a third-party script creates a network request to that provider. Custom tool events contain event name, tool identifier and page pathname, rather than pasted charts, body measurements or birth dates. Provider-side processing and retention are governed by Ahrefs' privacy policy. Browser extensions or browser settings may restrict these requests.

Google AdSense and advertising cookies

This site includes Google AdSense code using publisher ID ca-pub-1411631093585461. Code installation does not mean the site has been approved or that an advertisement appears on every visit. Google and other third-party advertising vendors may use cookies to serve ads based on prior visits to this website or other websites. Google's advertising cookies enable Google and its partners to serve ads based on visits to this site and other sites on the Internet.

Advertising requests can disclose technical information such as IP address, browser information and the page being visited to the advertising provider. The site's tool code does not intentionally include calculator inputs in ad requests. Cookies and browser storage used by third-party services are separate from the site's saved-tool preferences. See how Google uses information from sites that use its services and Google's advertising information.

Your advertising and browser choices

You can manage personalized advertising preferences through Google My Ad Center and review participating vendors' choices through the Digital Advertising Alliance opt-out page. Browser controls can also block or delete cookies and site storage. These choices do not guarantee the removal of all advertising or stop every technical request. Where a regional consent message is presented, use its controls to express your choices.

Email, source links and corrections

If you contact the listed email address, the mailbox provider receives the sender address and message you choose to send. Correction investigations may require the page, input and source example. Do not send payment information, identity documents, unredacted orders or private health information. External source websites have their own policies; following a source link leaves this site.

Updates and contact

This policy was updated on 2026-10-26 to describe the AdSense integration and the existing analytics and tool requests. Further material changes should be recorded with a new date. Privacy questions and requests can be sent using the address on Contact China Converters. Consult each provider's policy for its retention practices.
