Privacy Policy

How we handle information when you use our free online calculators.

This Privacy Policy explains what information is collected when you visit baikecalc and how it is used. This site is a static web application: it does not require you to create an account and does not ask you to submit personal information to use any calculator.

Information collected automatically

When you visit the site, our hosting provider (Cloudflare Pages) and, if enabled, analytics and advertising partners automatically receive standard technical information such as your IP address, browser type, device type, language preference, referring pages, and the date and time of your visit. This information is used only to operate, secure, and improve the site.

Cookies and advertising

We use cookies and similar technologies to remember your preferences and to serve personalized advertisements through Google AdSense. Advertisers may use cookies to build a profile of your interests based on your activity across websites. You can control non-essential cookies through the consent banner shown when you first visit the site, and you can change your choice at any time by clearing this site's storage.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of the DoubleClick cookie 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 personalized advertising at any time by visiting Ads Settings. If you are in the EU or UK, you can also withdraw consent for advertising cookies through the consent banner on this site.

To learn more about how Google uses data when you use our partners' sites and apps, visit Google's Advertising Policies. You can manage personalization at Ads Settings.

How we use information

  • To operate and secure the site.
  • To understand which tools are useful so we can improve them.
  • To display advertisements that help keep the calculators free.

Your rights

Depending on where you live (for example under the EU GDPR or the California CCPA), you may have the right to access, correct, or delete personal data and to object to certain processing. Because this site does not store personal data on its own servers, most requests relate to data held by our service providers, which we will help you address on request.
