Privacy Policy

1. Information We Collect

We collect only the minimum information needed to operate and improve the site. This includes:

• Usage data — pages visited, time spent, referrer URLs, browser type, device type, and operating system. Collected automatically via analytics tools.
• Cookies and similar technologies — small files stored on your device to remember preferences, measure traffic, and serve relevant ads.
• Contact information — only if you voluntarily reach out via email. We do not use contact forms that store submissions on our servers.

We do not collect names, email addresses, financial account numbers, Social Security numbers, or any sensitive personal data through the use of our calculators. All calculator inputs remain local to your browser session and are never transmitted to our servers.

2. Cookies

UseACalculator.com uses cookies for the following purposes:

• Analytics — to understand how visitors use the site and which tools are most useful.
• Advertising — Google AdSense uses cookies, including the DoubleClick cookie, to serve ads based on a visitor's prior browsing activity on this and other websites.
• Preferences — to remember display settings such as light or dark mode.

You can opt out of personalized advertising at any time by visiting Google Ad Settings or by using the NAI opt-out tool. Most browsers also allow you to block or delete cookies through their settings menus.

3. Third-Party Services

We use the following third-party services that may collect data under their own privacy policies:

• Google AdSense — serves advertisements on this site. Google's use of advertising cookies enables it and its partners to serve ads based on your visits here and elsewhere. Review Google's privacy practices at policies.google.com/privacy.
• Vercel Analytics — provides aggregated, anonymized traffic data to help us understand site performance. No personally identifiable information is shared.

4. How We Use Information

We use collected information solely to:

• Improve our calculators and editorial content
• Monitor and optimize site performance
• Maintain security and prevent abuse
• Deliver relevant advertising through Google AdSense
• Respond to inquiries you send us directly

We do not sell your personal information to third parties. We do not use your data to make automated decisions that significantly affect you.

5. Data Retention

Anonymized analytics data is retained for up to 26 months, after which it is automatically deleted or aggregated. If you contact us by email, we retain that correspondence for up to 2 years for reference purposes. We do not store calculator inputs — they exist only in your browser session and are discarded when you leave the page.

6. Your Rights — GDPR (EU/EEA Residents)

If you are located in the European Union or European Economic Area, you have the following rights under the GDPR:

8. Data Security

We take reasonable technical and organizational measures to protect any information we process — including HTTPS encryption for all site traffic and access controls on our analytics dashboards. No method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

9. Children's Privacy
