This policy explains what information EZ1 Calculators ("we", "us") collects when you use this website, how we use it, and the choices you have. Questions? Email support@ez1calculators.com.
The short version
- Our calculators are free and you do not need an account.
- We do not sell your personal information.
- We show ads and measure basic traffic to keep the site free.
- In the EU and UK we ask for your permission before using advertising and analytics cookies. You can change or withdraw your choice any time using "Cookie settings" in the footer.
Information we collect
Numbers you enter. The values you type into a calculator (for example a length or an interest rate) are sent to our server only to work out your result and show it back to you. We do not use them to identify you.
Automatic information. Like most websites, we automatically receive basic technical data such as your device type, browser, approximate region, and the pages you view. We use an anonymous identifier to count visits — not your name or email.
Cookies and similar technologies
Cookies are small files stored by your browser. We use two kinds:
- Essential — needed for the site to work (for example, remembering your cookie choice). These are always on.
- Non-essential — advertising and analytics cookies. Used only where permitted, and in the EU/UK only after you agree.
You can change or withdraw your choice at any time using the "Cookie settings" link in the page footer.
Advertising
We use Google AdSense to display ads. Depending on your location and choices, ads may be personalized (based on your interests) or non-personalized (based only on the page you are viewing). Google and its partners may use cookies to serve and measure ads. Learn more at Google's "How Google uses information from sites or apps that use our services" page (google.com/policies/privacy/partners). If you decline advertising cookies, you will still see ads, but they will be non-personalized.
Analytics
We use Google Analytics to understand how the site is used, and only after you accept analytics cookies. It uses an anonymous identifier; we do not collect your name or email.
Your choices
- Accept or decline non-essential cookies using the banner, and change or withdraw your choice any time via "Cookie settings" in the footer.
- EU / UK visitors. We ask before using advertising or analytics cookies.
- California visitors. We do not sell your personal information for money. Declining non-essential cookies also opts you out of data sharing for personalized ads.
- You can also control cookies through your browser settings.
Your rights
Depending on where you live, you may have the right to access, correct, or delete the personal information we hold about you, and to object to certain uses. To make a request, email support@ez1calculators.com.
Data retention
We keep anonymous analytics data only as long as needed to understand how the site is used. We do not keep the numbers you enter into calculators tied to your identity.
Children
This site is not directed to children under 16 and we do not knowingly collect their personal information.
Changes to this policy
We may update this policy from time to time. When we do, we will change the "Last updated" date above.
