Privacy Policy

This policy explains what information Calcora (accessible at letscalculate.online, "the site", "we", "us") collects, how it's used, and the choices available to you. By using the site, you agree to the practices described here.

Information the calculators themselves collect

None. Every calculator on this site runs locally in your browser using JavaScript — the numbers you type into a loan, BMI, pregnancy, or any other calculator are never sent to our servers, stored by us, or seen by us. Closing the tab clears them.

Cookies and similar technologies

Like most websites, Calcora and the third-party services it uses (below) rely on cookies, local storage, and similar technologies to operate and to serve relevant advertising.

Google AdSense

This site displays advertising served by Google AdSense. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet.

You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info/choices. For more on how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

Google Analytics

We use Google Analytics to understand aggregate traffic patterns — which pages are visited and how often — so we know which calculators are useful and where the site needs work. Google Analytics uses cookies to collect standard internet log information and visitor behavior in an anonymous form; this data is not used to identify you personally. You can prevent this data from being used by Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

Information we collect directly

If you email us through the Contact page, we receive whatever you choose to include — typically your email address and the content of your message. We use this only to respond to you and don't add it to a mailing list or share it with third parties.

Children's privacy

Calcora is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we'll remove it.

Your rights

Depending on where you live, you may have rights to access, correct, or delete personal data, and to opt out of its sale or of targeted advertising (for example, under the GDPR in the EU/UK or the CCPA in California). Because we don't collect personal data beyond what's described above, there's typically little to act on — but you can reach us at any time through the Contact page with a request, and for third-party advertising data specifically, the opt-out links above are the most direct route.

Data retention and security

We don't operate a database of visitor information ourselves; calculator inputs never leave your browser. Aggregate analytics data is retained by Google according to their own retention settings. We don't sell personal information.

Changes to this policy

If this policy changes, the update will be posted here with a revised "last updated" date. Continued use of the site after a change means you accept the revised policy.
