Privacy Policy

Your privacy is important to us. This policy explains what information MegaCalc collects, how we use it, and your choices regarding your information.

Information We Collect

We collect minimal information to operate the service. When you use MegaCalc, our servers log standard web server data including your IP address, browser type, referring URLs, and pages visited. This data is used solely for operating and improving the service, including to count page loads per page and per day; those counts keep no IP addresses or browser details. It is not sold or shared with third parties for marketing purposes.

Cookie Consent and Your Choices

When you first visit MegaCalc, a cookie banner asks whether you accept analytics cookies (and advertising cookies when ads are shown). Accept turns Google Analytics cookies on; Reject keeps them off. While no ads are shown, accepting allows analytics storage only; Google's advertising signals (ad storage, ad user data and ad personalization) stay denied. Your choice is stored in your browser's local storage so we don't ask again on every visit. If your browser lets the site read a stored Accept but neither replace nor remove it, your Reject is kept instead in a small first-party cookie, megacalc_consent, that only records that you refused; it lasts up to 180 days, and accepting removes it. You can change it at any time with the "Cookie settings" button at the bottom of every page except embedded calculators, which show neither the banner nor that button. If you switch from Accept to Reject, the site tells Google's tags to stop using cookies, in every MegaCalc tab you have open, and deletes the Google Analytics and Google advertising cookies set for megacalc.org in your browser.

Cookies and Analytics

MegaCalc uses cookies and similar technologies for analytics (to understand how visitors use our site) and, when advertising is enabled, to serve advertisements via Google AdSense. We implement Google Consent Mode v2, which means analytics and advertising cookies are not set until you accept them in our cookie banner. Until you accept, or after you reject, Google's tag still sends cookieless measurement pings (for example, that a page was viewed) that do not read or write cookies. When ads are shown and you reject cookies, Google serves only non-personalized (contextual) ads based on page content rather than your browsing history. Our analytics cookies belong to megacalc.org only and are not used to follow you across other websites; advertising cookies, when ads are shown, are Google's (see Google AdSense below).

Google AdSense

MegaCalc does not show ads at the moment: the Google AdSense script and ad slots are only included when advertising is switched on for the site, and it is off. If advertising is switched on, Google AdSense will show ads; with your consent Google may use cookies to show ads based on your visits to this and other websites, and without it Google shows contextual ads only. You can opt out of personalized advertising at any time by visiting Google's Ads Settings (adssettings.google.com) or the Digital Advertising Alliance opt-out at www.aboutads.info. For more information about how Google uses data, see Google's Privacy Policy at policies.google.com/privacy.

Data We Do Not Collect

MegaCalc does not require account registration and does not collect names, email addresses, or passwords. The values you enter into calculators and the amounts you convert are processed entirely in your browser; they are not transmitted to or stored on our servers and are never included in the analytics events the site sends. The currency and crypto converters ask our server for current rates for the currencies you pick, but never send it your amounts. A "Copy link with inputs" link puts your values in the part of the address after "#", which browsers do not send to our servers — share such links only with people who may see those values. The page addresses the site gives Google Analytics leave out that part, and any words typed into site search.

Third-Party Links

Our site may contain links to third-party websites. We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies.

Children's Privacy

MegaCalc is not directed at children under 13 years of age. We do not knowingly collect personal information from children. If you believe a child has provided personal information, please contact us and we will delete it promptly.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Continued use of MegaCalc after changes constitutes acceptance of the updated policy.
