Privacy Policy
Last updated: 2 October 2026
This policy explains what information CY Calculator (“we”, “us”) collects when you use this website, how it is used, and the choices you have.
Calculator inputs
The numbers you enter into our calculators are processed only in your browser. They are not sent to our servers, saved, or linked to you. We do not offer accounts or collect names, emails or other personal details through the calculators.
Information collected automatically
Like most websites, our hosting provider and content delivery network may automatically record technical information such as your IP address, browser type, device type, pages requested and the date and time of the request. This is used to deliver the site, keep it secure and diagnose problems.
Cookies and advertising
We may use Google AdSense to show ads. 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.
- Google and its partners may use cookies, web beacons, device identifiers and similar technologies to show and measure ads and to prevent fraud and abuse.

Non-personalised ads may still be shown if you opt out of personalised advertising. You can also control or delete cookies in your browser settings; blocking all cookies may affect how some websites work.

Where required, we use a consent management platform certified by Google to ask for your consent, and you can change your choice at any time through the privacy controls on the site.

We do not currently use third-party analytics tools. If we add any, we will describe them here and, where required, ask for your consent first.
