Privacy Policy

We don't ask you for personal data ourselves. However, the site uses Google Analytics, Google AdSense, and Adsterra — third parties that collect data about your visit under their own privacy policies. Your rights under GDPR and CCPA are explained below.

The short version

We don't ask you for personal information ourselves. All calculations on this site run entirely in your browser — your inputs never reach our server. However, the site loads scripts from Google Analytics (page-view counts), Google AdSense (display ads), and Adsterra (additional ad network). These third parties collect data about your visit under their own privacy policies. The sections below describe what they collect, what we collect directly, and what rights you have.

What WE collect directly

What THIRD PARTIES collect

This site loads scripts from third-party services that collect data about your visit. Under GDPR and most US state privacy laws, this counts as personal data even though we never see it directly.

Google Analytics

We use Google Analytics to count visits and understand which calculators are most used. Google Analytics collects: your IP address, a cookie identifier, device and browser information, approximate location (from IP), language, and pages viewed. Google acts as our data processor for Analytics. See Google's privacy policy, and how Google Analytics safeguards data. You can opt out site-wide using the Google Analytics opt-out browser add-on.

Google AdSense

We use AdSense to display ads. AdSense uses cookies and device identifiers to serve ads, which may be personalized based on your prior browsing across the web. Google acts as an independent data controller for AdSense data. See how Google uses data when you visit a partner's site. You can opt out of personalized ads at Google Ads Settings, at Your Online Choices (EU/UK), or YourAdChoices (US).

Adsterra

We use Adsterra as an additional advertising network. Adsterra and its advertising partners use cookies and similar technologies to serve and measure ads. Adsterra acts as an independent data controller for the data it collects. See Adsterra's privacy policy for details and opt-out mechanisms.

Google Fonts

We load typefaces from Google Fonts. Google sees a request from your browser (IP, user agent) when you load the site. We don't send extra information.

Cookies and similar technologies

This site uses or causes to be used:

You can clear cookies for this site via your browser settings without losing core functionality. Where required by applicable law, we ask for consent before non-essential cookies are placed.

Your rights (GDPR, CCPA/CPRA, and similar)

Privacy laws give you rights over data collected about you. Because we hold almost no personal data directly, most of these rights are exercised against the third parties listed above — but here they are:

If you're in the EU, EEA, UK, or Switzerland (GDPR / UK GDPR)

If you're a California resident (CCPA / CPRA)

Other jurisdictions

If you're in another US state with a comprehensive privacy law (Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, and others), in Brazil (LGPD), Canada (PIPEDA), Australia, or anywhere else with similar legislation, equivalent rights generally apply. Contact us and we'll handle your request consistent with applicable law.

How to exercise your rights

Legal bases for processing (GDPR Article 6)

Data retention

International transfers

Google and Adsterra operate globally. Personal data collected by them may be transferred to and stored in the United States and other jurisdictions. Those transfers are governed by the third parties' own safeguards (such as the EU-US Data Privacy Framework, Standard Contractual Clauses, or equivalent mechanisms). See their privacy policies for details.

Children

This site is not directed at children under 16. We don't knowingly collect personal data from children. If you believe a child has provided personal data to us, contact us and we'll delete it.

Changes to this policy

If we update this policy materially, we'll change the "Last updated" date at the top. Continued use of the site after a change indicates acceptance of the updated policy.
