Overview
Calquto ("we," "us," or "this site") provides free online calculators and tools. This Privacy Policy explains what information is collected when you use Calquto, how it's used, and your choices regarding that information. We built Calquto to respect your privacy by design — nearly every calculator on this site runs entirely in your browser, meaning the numbers you enter are never transmitted to or stored on our servers.
Information We Do Not Collect
The calculators and tools on Calquto (including financial, health, date/time, and text-based tools, as well as any new tools added in the future) process your input locally in your browser using JavaScript. We do not receive, log, or store the values you type into any calculator — including financial figures, health information, dates, or any other personal data entered into a tool.
Information Collected Automatically
Like most websites, Calquto and its third-party partners may automatically collect limited technical information when you visit, including:
- Browser type and version
- Device type and operating system
- Pages visited and time spent on the site
- General geographic location (derived from IP address, not precise location)
- Referring website or search engine
This information is typically collected through standard analytics and advertising technologies described below, and is used in aggregate to understand site usage and improve our tools — not to identify individual visitors personally.
Cookies and Third-Party Advertising
Calquto uses or may use Google AdSense to display advertising on this site. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this website and other websites on the internet.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to Calquto and/or other sites. You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of some third-party vendor cookies for personalized advertising by visiting www.aboutads.info.
Third-party advertising partners may also use web beacons or similar technologies to collect information as a result of ad serving on this site. We do not control the cookies placed by third-party advertising networks, and this Privacy Policy does not cover their use of your information — please refer to each third party's own privacy policy for details.
Analytics
We may use analytics services (such as Google Analytics) to understand how visitors use Calquto. These services may use cookies and similar technologies to collect anonymized or pseudonymized usage data, which helps us identify popular tools and improve site performance.
Children's Privacy
Calquto is not directed at children under the age of 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through this site, please contact us so we can address it.
Data Security
Since most calculations happen entirely in your browser and are never transmitted to us, there is no server-side storage of your calculator inputs to secure. For the limited technical and analytics data described above, we rely on standard industry security practices used by our hosting and analytics providers.
Your Choices
You can control cookies through your browser settings, including blocking or deleting cookies. Note that disabling cookies may affect how ads are displayed but will not affect your ability to use any calculator or tool on Calquto, since these function independently of cookies.
Changes to This Policy
We may update this Privacy Policy from time to time, particularly as we add new tools or features to Calquto. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this page periodically.
