Privacy Policy

Last updated: 2026.

OmniCalc ("we", "us") is built to be privacy-light. All calculators run entirely in your browser — the values you enter are never sent to or stored on our servers. This policy explains what limited data is processed when you use the site.

Information we process

• Calculator inputs stay on your device and are not transmitted to us.
• Aggregate analytics (page views, country, device type) may be collected with a privacy-friendly, cookieless tool to understand traffic.
• Advertising and cookies as described below, once advertising is enabled.

Cookies

A cookie is a small file stored on your device. We may use: essential cookies for basic functionality; analytics; and, when ads are enabled, advertising cookies set by Google and other third parties. You can control or delete cookies in your browser settings.

Advertising (Google AdSense)

This site may use Google AdSense to display advertisements. In connection with serving ads:

• Third-party vendors, including Google, use 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 to you 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.
• You can opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info.

Consent (EEA, UK & Switzerland)

For visitors in the European Economic Area, the United Kingdom and Switzerland, we use a Google-certified consent management platform to request consent for the use of cookies and personal data for personalized advertising, in line with Google's EU User Consent Policy. Non-personalized ads may be shown where consent is declined.
