Privacy Policy


Privacy Policy

Effective Date: April 8, 2026

This Privacy Policy describes how Rational Growth (“we”, “us”, “the site”) collects, uses, and protects information when you visit https://rational-growth.com. By using the site you agree to the practices described below.

1. Information We Collect

We collect only the data needed to operate, secure, and improve the site:

  • Comments: When you leave a comment, we collect the data shown in the comment form (display name, email address, optional website URL), plus your IP address and browser user-agent string for spam protection. The Gravatar service may receive a hashed version of your email address to display your profile picture.
  • Contact Submissions: If you email us, we store your email address and the content of your message for as long as needed to respond.
  • Server Logs: Our hosting provider (Hostinger) automatically logs IP addresses, request times, browser type, and referring URLs for security and abuse-prevention purposes. These logs are retained for a limited period and are not used for advertising.
  • Analytics: We use Google Analytics 4 to measure aggregate usage (pages visited, time on site, country, device type). Analytics data is pseudonymized and we do not link it to identifiable individuals.
  • Cookies and Local Storage: Both strictly necessary cookies (e.g. for login state and consent preferences) and analytics/advertising cookies (described in section 3) may be set in your browser.

2. How We Use Information

  • To deliver and maintain the site and respond to your inquiries
  • To analyze aggregate traffic patterns and improve content quality
  • To display relevant advertising through Google AdSense (see section 3)
  • To prevent fraud, spam, and abuse
  • To comply with legal obligations

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

3. Third-Party Advertising — Google AdSense

This site uses Google AdSense, a third-party advertising service operated by Google LLC, to display advertisements.

  • Google, as a third-party vendor, uses cookies to serve ads on this site.
  • Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and other sites on the Internet.
  • Google uses the DART cookie to display interest-based advertisements based on browsing activity. Users may opt out of the DART cookie by visiting the Google ads and content network privacy policy.
  • You may also opt out of personalized advertising entirely by visiting aboutads.info/choices or youronlinechoices.eu.
  • Third-party vendors and ad networks may also serve ads on this site. They may use cookies, web beacons, or similar technologies to measure ad effectiveness or personalize content. We do not control these third parties’ tracking technologies.

4. Other Third-Party Services

5. Cookies and Tracking

We and our partners use the following categories of cookies:

  • Strictly Necessary: Required for the site to function (login state, consent preference). These cannot be disabled.
  • Analytics: Help us understand which pages are most useful so we can improve content. You can opt out via your browser’s “Do Not Track” setting or by installing the Google Analytics opt-out browser add-on.
  • Advertising: Used by Google AdSense and partner ad networks to serve and measure relevant advertising.

You can clear or block cookies through your browser settings. Doing so may affect site functionality.

6. GDPR (European Economic Area Visitors)

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, you have the following rights under the General Data Protection Regulation (GDPR):

  • The right to access, correct, or delete your personal data
  • The right to restrict or object to processing
  • The right to data portability
  • The right to withdraw consent at any time
  • The right to lodge a complaint with your national data protection authority

Our legal basis for processing personal data is your consent (where applicable), legitimate interests (site security, analytics, content improvement), and performance of a service when you contact us.

7. CCPA (California Residents)

Under the California Consumer Privacy Act (CCPA), California residents have the right to:

  • Know what categories of personal information we collect and how we use it
  • Request deletion of personal information we hold about them
  • Opt out of the sale of personal information (we do not sell personal information)
  • Be free from discrimination for exercising CCPA rights

8. Children’s Privacy

This site is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it promptly. We comply with the Children’s Online Privacy Protection Act (COPPA).

9. Data Retention

Comments and the data they contain are retained indefinitely so that we can recognize and approve any follow-up comments automatically. Analytics data is retained for the default Google Analytics retention window. Server logs are retained for security purposes for a limited period and then deleted or anonymized.

10. Data Security

We take reasonable technical and organizational measures to protect the data we hold, including HTTPS encryption for all traffic, restricted administrative access, and regular software updates. No system is perfectly secure, however, and we cannot guarantee absolute security.

11. Changes to This Policy

We may update this Privacy Policy from time to time as our practices, third-party services, or applicable laws change. Material changes will be reflected in the “Effective Date” at the top of this page. Continued use of the site after a change constitutes acceptance of the updated policy.
