Privacy Policy

What we collect

This site is built as a set of static pages with no accounts and no backend. Every calculator runs with JavaScript in your own browser. The numbers you type into any tool are processed on your device and are never sent to our servers, stored, or shared with anyone.

Cookies

This site itself does not place cookies. If and when advertising is enabled, third-party advertising partners may use cookies or similar technologies to serve ads, measure their performance, and show you ads that are more relevant to you. These cookies are set and controlled by the advertising providers, not by us.

Third-party advertising providers

We may show ads served by Google AdSense. Google, as a third-party vendor, uses cookies to serve ads on this site. The use of advertising cookies enables Google and its partners to serve ads to users based on visits to this site and other sites on the internet.

DoubleClick cookie

Google may use the DoubleClick cookie (and similar mechanisms) to enable its partners to serve ads based on a user previous visits to this or other websites. You can learn more about how Google uses advertising cookies at the Google Advertising page.

Opting out of personalized advertising

You can opt out of personalized advertising by visiting Google Ads Settings at adssettings.google.com. You can also opt out of some third-party vendor cookies by visiting www.aboutads.info, which lets you manage choices offered by participating companies, including the option to opt out of interest-based advertising.

Logs and hosting

Like any website, our hosting provider keeps standard server logs (IP address, browser type, pages requested) for security and performance. These logs are not used to identify visitors and are not sold.

Data we never collect

We do not collect names, email addresses, payment details, or any calculation inputs. There is no registration, no newsletter, and no analytics that reads your calculator entries.

External links

Pages may link to external sites (for example, official sources or advertising partners). We are not responsible for the privacy practices of those sites; please review their own policies.

Changes

If this policy changes, we will update this page. The version date below shows when it was last reviewed.

Your rights

Because we collect no personal data about you, there is nothing to access, correct or delete on our side. If you contact us by email, we use your address only to reply and keep the conversation thread no longer than needed.

Children

This site is intended for general audiences and does not knowingly collect information from children. If you believe a child has shared personal data with us, contact us and we will remove it.

Questions

For any privacy question, email us at hello@fincalcs.xyz. We will answer what we do with data honestly: almost nothing, because the tools run on your device.

We do not run remarketing pixels, cross-site trackers or fingerprinting scripts, and we have no data to sell because we collect none.

This policy is part of our commitment to keeping the calculators free, private and simple, and it applies to every page on this domain.
