This Privacy Policy describes how KineticMetrix ("we", "us", or "our") collects, uses, and shares information when you visit kineticmetrix.com (the "Site"). Please read it carefully.

1. Information We Collect

Information you enter into calculators

When you use our calculators, you enter health-related data (such as weight, height, age, and activity level). This information is not stored, logged, or transmitted to us. It is sent to our API server solely to compute your result and is not retained after the response is returned to your browser. We do not create user accounts and have no way to identify individual users from calculator inputs.

Automatically collected data

Like most websites, we receive certain information automatically when you visit:

  • Log data: Your IP address, browser type, operating system, referring URL, pages visited, and timestamps may be recorded in standard server logs. These logs are used for security and operational monitoring and are retained for up to 30 days.
  • Cookies: See Section 3 below.

Information we do not collect

We do not collect names, email addresses, postal addresses, phone numbers, or payment information. We do not create user accounts. We do not knowingly collect personal information from children under 13.

2. How We Use Information

We use the information described above to:

  • Operate and maintain the Site
  • Serve relevant advertisements via Google AdSense
  • Monitor and improve site performance and security
  • Comply with legal obligations

We do not sell, rent, or trade your personal information to third parties for their marketing purposes.

3. Cookies

Cookies are small text files stored on your device by your browser. We use cookies for the following purposes:

Cookie typePurposeSet by
FunctionalCookie consent preference storageKineticMetrix / Google Consent Management
Advertising (Google AdSense)Ad personalisation and measurement (e.g. NID, IDE)Google — only after you consent

We do not set advertising cookies unless you give consent. If you consent, Google AdSense may set cookies for ad personalisation and measurement. If you decline or do not respond to the banner, no advertising cookies are set; non-personalised ads may still be shown without cookies. Consent is managed through a banner provided by Google's Consent Management Platform.

You can clear your stored preference at any time by clearing your browser's local storage.

4. Third-Party Services

Google AdSense

This Site displays advertisements through Google AdSense. The site implements Google Consent Mode v2 with all consent signals defaulting to "denied", and consent is managed via a banner provided by Google's Consent Management Platform. Details:

  • Personalised advertising is only served if you consent via the banner.
  • If you decline or do not respond, no advertising cookies are set; non-personalised (contextual) ads may still be displayed, without cookies.
  • You can change or withdraw your choice at any time via the banner's "Options" (manage settings) link or by clearing your browser's cookies.
  • Google's own privacy controls remain available at Google Ads Settings.

Amazon Associates

Some pages contain affiliate links to Amazon. When you click these links, Amazon may set cookies to track referrals. Amazon's privacy practices are governed by Amazon's Privacy Notice.

5. Your Rights

European Economic Area (GDPR)

If you are located in the EEA, you have the following rights regarding your personal data:

  • Right of access: Request a copy of the personal data we hold about you.
  • Right to rectification: Request correction of inaccurate data.
  • Right to erasure: Request deletion of your personal data ("right to be forgotten").
  • Right to restrict processing: Request that we limit how we use your data.
  • Right to data portability: Receive your data in a structured, machine-readable format.
  • Right to object: Object to processing based on legitimate interests or for direct marketing.
  • Right to withdraw consent: Withdraw consent for cookie-based processing at any time.

Our legal basis for processing is: (a) legitimate interests (for server log security monitoring); (b) consent (GDPR Art. 6(1)(a) and Art. 5(3) ePrivacy) for advertising cookies — advertising cookies are set only with your consent. Non-personalised ads shown without cookies do not require consent.

California Residents (CCPA/CPRA) and other US states

California residents have the right to know what personal information is collected and whether it is sold or shared, and to request deletion of personal information. We do not sell personal information. However, like most websites with advertising, we may "share" personal information with advertising partners (such as Google AdSense) for personalised advertising. If you are in California or another US state with a comprehensive privacy law, you may opt out of the sale or sharing of your personal information for advertising purposes by using the "Do Not Sell or Share My Personal Information" control provided in Google's US states privacy message on this Site — or by contacting us at the address below. Opting out does not stop non-personalised ads or reduce the functionality of the calculators.

International Data Transfers

Google AdSense is active on this Site. When ads are served, certain data (including, in some cases, your IP address) may be transferred to Google LLC in the United States. Such transfers are safeguarded by Standard Contractual Clauses (Art. 46(2)(c) GDPR) and/or the EU-US Data Privacy Framework.

Supervisory Authority

You have the right to lodge a complaint with a data protection supervisory authority. The authority responsible for us is:

Der Landesbeauftragte für den Datenschutz und die Informationsfreiheit Baden-Württemberg (LfDI BW)
Lautenschlagerstraße 20, 70173 Stuttgart, Germany
Website: www.baden-wuerttemberg.datenschutz.de

6. Data Retention

Server log files are retained for up to 30 days for security purposes. Calculator inputs are not stored at all — they are discarded after the API returns your result. Cookie consent preferences are stored in your browser's local storage until you clear them.

7. Security

We use HTTPS (enforced via Let's Encrypt TLS certificates) to encrypt all data in transit between your browser and our servers. Our API server does not log calculator inputs. We apply standard server hardening practices to our infrastructure.

8. Children's Privacy

The Site is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe we have inadvertently collected data from a child, please contact us and we will delete it.

9. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page will reflect the most recent revision. Material changes will be noted prominently on the Site.
