Calculation data
All calculation arithmetic runs in your browser. We do not send the prices, costs, quantities, or other calculation inputs to a server. They are not included in page URLs. This version has no accounts or server-side calculation database.
Temporary browser storage
We use sessionStorage in your current tab to remember calculator inputs, currency, and conversion mode. These are used to continue your work between tools and languages. Reset example clears the saved calculation session.
Session storage normally lasts for the tab’s browsing session, but browser session restoration may restore it too. Reset or clear site data to remove it explicitly. If storage is blocked, calculations still work but inputs may not carry across pages.
Advertising and cookies
Google AdSense code loads on every page. Third-party vendors, including Google, may use cookies or similar technologies to serve and measure ads based on previous visits to this website or other websites. We do not use a separate analytics service.
When Google ads are shown, Google’s advertising cookies enable Google and its partners to serve ads based on visits to this site and/or other sites on the Internet. Other third-party vendors and ad networks selected in AdSense may also use cookies for advertising and measurement.
You can manage or opt out of personalized advertising with Google Ads Settings. AboutAds offers opt-outs for participating third-party vendors. These choices do not necessarily remove all ads. Google Ads Settings · AboutAds
The ad technology partners and consent choices depend on the publisher’s AdSense settings. Where consent is required, the operator should provide a consent message identifying selected partners and their data practices. You can also review Google’s ad partner directory.

Hosting and contact
Page requests still travel through the hosting provider, which may process technical request information such as IP addresses and browser headers to deliver and secure the site. Calculator values are not part of those requests.
If you contact the operator by email, your email provider and the receiving provider handle that message. Do not include confidential customer or financial records. See the contact page for available operator details.
