Privacy Policy

1. Information We Collect

Rio Calculator is designed with privacy in mind. All calculator computations happen entirely within your browser — we do not collect, store, or transmit any numbers you input into our calculators.

We may collect limited non-personal information through standard web analytics, including:

• Pages visited and time spent on site
• Browser type and operating system
• Referring website
• General geographic location (country level)

2. How We Use Information

Analytics data is used solely to understand how visitors use our site, improve our calculators, and identify popular tools. We do not sell or share this data with third parties for marketing purposes.

3. Cookies

We may use minimal cookies for analytics (e.g., Google Analytics) and to support Google AdSense advertisements. You can disable cookies in your browser settings, though this may affect some functionality.

4. Google AdSense

Rio Calculator uses Google AdSense to display advertisements. Google may use cookies to serve ads based on your prior visits to our site or other websites. You can opt out of personalized advertising by visiting Google Ads Settings.

5. Third-Party Services

Our site may use third-party services including Google Analytics and Google AdSense. These services have their own privacy policies governing how they use your information.

6. Data Security

Since we do not store personal or financial data on our servers, the risk to your data is minimal. All calculator inputs remain on your device and are never transmitted.

7. Children's Privacy

Rio Calculator does not knowingly collect personal information from children under 13. Our services are intended for general audiences.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected with an updated date at the top of this page.
