Privacy Policy
This Privacy Policy explains how creatinineclearancecalculator.com ("we", "us", or "our") handles information when you use our website.
1. Who we are
This website provides an educational creatinine clearance calculator and related clinical information at https://creatinineclearancecalculator.com.
2. Information we collect
2.1 Calculator inputs
Age, sex, weight, height, serum creatinine, and similar values you enter into the calculator are processed locally in your browser for the calculation. We do not post those clinical values to our servers as a patient record. If you accept analytics cookies, third-party tools may receive technical usage data (see section 6). Form fields are masked in Microsoft Clarity session replay.
2.2 Automatically collected technical data
Like most websites, our hosting environment and third-party services may automatically receive standard technical information such as IP address, browser type, device type, referring URL, pages visited, and approximate location derived from IP address.
2.3 Information you send us
If you contact us by email or another channel, we receive the information you choose to include in that message.
3. How we use information
- To operate, secure, and improve the website
- To measure aggregate traffic and understand how the site is used
- To show advertisements (including through Google AdSense), where enabled
- To respond to inquiries and meet legal obligations
4. Cookies and similar technologies
We use cookies and similar technologies for essential site functions and theme preference. Google Analytics and Microsoft Clarity load only after you accept the cookie banner. Details and a “Change cookie choice” control are in our Cookie Policy.
5. Google AdSense and advertising partners
We may use Google AdSense and other advertising partners to display ads. These partners may use cookies, web beacons, and similar technologies to collect information about your visits to this and other websites in order to provide personalized or non-personalized ads, measure ad performance, and prevent fraud.
Google's use of advertising cookies is described in Google's policies, including:
You can control personalized advertising through Google's Ads Settings: https://adssettings.google.com/.
6. Analytics
If you click Accept on the cookie banner, we load Google Analytics 4 (measurement ID G-9KZDWJEY18) and Microsoft Clarity (project xwjli2nenm). These services can receive IP address, device/browser data, pages viewed, and (for Clarity) a session recording. Calculator inputs are masked in Clarity. If you click Reject, those scripts are not loaded. You can change your choice on the Cookie Policy page.
7. Legal bases (where applicable)
Depending on your location, we may process information based on legitimate interests (site security and improvement), consent (optional cookies/ads where required), and/or compliance with legal obligations.
8. Data retention
Calculator inputs are not stored by us on a server. Theme preference and your cookie choice are stored in your browser until you clear them. If you accepted analytics, Google and Microsoft retain usage data according to their policies. Hosting logs are kept only as needed for security and operations.
9. Children's privacy
This website is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children.
10. International visitors
If you access the site from outside the country where our hosting or service providers operate, your information may be processed in other countries that may have different data-protection laws.
11. Your choices and rights
Depending on applicable law, you may have rights to access, correct, delete, or restrict certain processing of personal information, or to withdraw cookie consent. You can also clear cookies in your browser and adjust advertising preferences with Google.
12. Security
We take reasonable technical and organizational measures to protect the website. No method of transmission or storage is completely secure.
13. Third-party links
Our pages may link to third-party websites. We are not responsible for their privacy practices. Please review their policies separately.
14. Changes to this policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top will change when we do. Continued use of the site after updates means you acknowledge the revised policy.
