Privacy Policy

What stays in your browser

All calculator inputs and results are processed entirely in your browser — no input values are ever sent to our servers. Calculation history, saved favourites, and recently viewed calculators are stored in your browser's localStorage and are never transmitted anywhere. You can clear this data at any time from the History and Favourites pages.

Analytics

We use Cloudflare Web Analytics, which is cookieless and does not track individual users across sessions or sites. It collects aggregate data (page views, referrers, browser type, country) with no personally identifiable information. No consent banner is required because no cookies are set and no personal data is collected under GDPR/DPDP definitions.

We may add Google Analytics 4 in the future if AdSense reporting requires it. If that happens, this policy will be updated before GA4 is enabled, and a consent mechanism will be added as required.

Advertising

This site shows ads served by Google AdSense. Google and its advertising partners use cookies and similar technologies to serve ads based on your prior visits to this and other websites, and to measure ad performance. This is separate from the analytics described above — no calculator input values are ever shared with Google or any advertiser.

You can see and manage the interest categories Google has associated with your browser, or opt out of personalised advertising entirely, at Google Ads Settings. You can also opt out of personalised advertising from participating providers at aboutads.info. See Google's own How Google uses information from sites that use its services for full detail on what AdSense collects.

Currency rates

The currency converter fetches exchange rates from a Cloudflare Worker endpoint, which in turn fetches from a third-party API (open.er-api.com). Only the request for the rate table is made — no input values from the calculator are included. The rate table is cached for up to 6 hours.

Cookies

We do not set any first-party cookies. Cloudflare may set cookies for security purposes (bot detection, DDoS protection) as part of serving the site. These are Cloudflare's cookies, not ours.
