Privacy Policy

The short version

CorrectCalc is designed to collect as little as possible. Every calculator on this site runs entirely in your browser. The numbers you enter — loan amounts, incomes, balances — are never transmitted to us or to any server. There is no account system and nothing to breach.

What stays on your device

All calculations happen locally in your browser's JavaScript. Inputs exist only in the page's memory while you use it. We do not store, log or see the figures you calculate.

What this website collects

• Standard technical logs. Like nearly all websites, our hosting provider (Cloudflare) records basic request data such as IP address, browser type and pages visited, used for security and performance.
• Analytics (when enabled). We use Google Analytics 4 to understand which calculators are useful. GA4 collects anonymized usage data such as page views and approximate location. You can block analytics with any standard browser setting or extension.

Advertising and cookies

This site is free because of advertising. When ads are enabled, we use Google AdSense. Google and its partners may set cookies or use device identifiers to show ads relevant to your interests, and to measure ad performance. You can review or change your choices at Google Ad Settings and learn more at Google's advertising policy. Visitors from the European Economic Area, the UK and Switzerland are shown a consent notice before advertising cookies are set, in accordance with GDPR.

Affiliate links

Some pages may contain affiliate links to third-party financial products. If you open an account through such a link, we may earn a commission at no additional cost to you. This never affects which tools we recommend or the math on this site. See our Terms of Use for the full disclosure.

Your rights

Depending on where you live, you may have rights to access, correct or delete personal data under laws such as the GDPR or CCPA. Because we collect so little, most requests simply have nothing to act on — but you can always reach us at [email protected].

Changes to this policy

We will update this page whenever our practices change and revise the date above. Material changes will be highlighted on the homepage.
