Who we are

CostWise Calculator ("we", "our", "us") operates this website at costwisecalculator.com. We publish free calculators that help users estimate everyday spending and compare financial decisions. Learn more on our About page.

What we collect

Calculator inputs: The numbers you enter into a calculator stay in your browser. We do not transmit, log, or store them on our servers.

Anonymous analytics: We use privacy-respecting analytics to count page views, referring sites, browser type, and approximate country. No personally identifying information is collected.

If you contact us by email: We retain your message and email address only as long as needed to reply.

Cookies and similar technologies

We may use cookies for analytics and to remember non-sensitive preferences (such as your chosen theme). Third-party advertising partners — including Google AdSense — may use cookies and identifiers to serve ads relevant to your interests. You can manage cookies through your browser settings or opt out of personalized ads at Google Ads Settings and aboutads.info.

Advertising

This site is supported by display advertising. Advertising partners may collect data through cookies and similar technologies to deliver and measure ads. We do not share calculator inputs or any user-provided data with advertisers.

Third-party services

We use trusted infrastructure providers for hosting, analytics, and advertising. Each partner operates under its own privacy policy. We do not sell or rent personal data.

Your rights (GDPR / CCPA)

Depending on your jurisdiction, you may have the right to access, correct, delete, or restrict use of personal data we hold about you, and to opt out of the "sale" or "sharing" of personal information. To exercise any of these rights, contact us via the Contact page.
