Privacy Policy

Last updated: 16 July 2026

1. Information you provide voluntarily

You can browse the Website without creating an account. If you contact the Website owner by email, subscribe through a newsletter form, or otherwise submit information voluntarily, the information supplied may include your name, email address, and the contents of your message. Such information is used only to respond, provide the requested communication, administer the subscription, or address a legitimate inquiry.

Please do not submit confidential, sensitive, medical, financial, or other information that is not necessary for your inquiry.

2. Information collected automatically

When you visit the Website, the hosting provider and third-party services used by the Website may automatically receive technical and usage information. Depending on the service and your settings, this may include:

• Internet Protocol (IP) address or an approximate location derived from it;
• browser, device, and operating-system information;
• referring and exit pages;
• pages viewed, links selected, and approximate time spent on pages;
• cookie identifiers and similar online identifiers; and
• diagnostic, security, and performance information.

3. GitHub Pages hosting

The Website is hosted using GitHub Pages. GitHub may process technical data, including server logs and IP-address information, to provide, secure, and maintain its hosting services. GitHub’s handling of personal data is governed by the GitHub Privacy Statement.

4. Google Analytics

The Website may use Google Analytics to measure visits and understand how visitors interact with its content. Google Analytics may use cookies or similar technologies and may collect information such as device details, approximate location, referral source, pages visited, and engagement information. These data are used to evaluate Website performance and improve content.

More information is available in Google’s Privacy Policy and How Google uses information from sites or apps that use its services. Visitors may also use the Google Analytics opt-out browser add-on, where supported.

5. Google AdSense and advertising cookies

The Website may display advertising supplied by Google AdSense and its advertising partners. Google and other third-party vendors may use cookies, web beacons, IP addresses, or similar technologies to serve, limit, personalize, and measure advertisements. Google’s use of advertising cookies may enable Google and its partners to serve advertisements based on a visitor’s activity on this Website or other websites.

Visitors can learn about or manage Google advertising personalization through Google Ad Settings. Additional information is available in Google’s advertising policies and technologies. Other advertising partners may provide their own opt-out mechanisms and privacy notices.

6. Consent choices

Where required by law, visitors may be shown a consent message before non-essential cookies or similar technologies are used. The available options may include accepting, rejecting, or managing purposes and vendors. A refusal of personalized advertising does not necessarily prevent all advertising cookies; some technologies may still be used for security, fraud prevention, frequency capping, aggregated reporting, or other legally permitted purposes.

7. ShareThis and social-sharing features

The Website may use ShareThis buttons or related social-sharing functionality. ShareThis and the social platforms selected by a visitor may collect device, browser, cookie, and usage information when those services are loaded or used. Their processing is governed by their respective privacy policies. See the ShareThis Privacy Notice.

8. Cookies and similar technologies

Cookies are small files stored on a visitor’s device. They may be used for essential functions, analytics, advertising, consent preferences, fraud prevention, and social-sharing features. A fuller explanation is provided in the Cookie Policy.

9. How information is used

Information may be used to:

• operate, maintain, secure, and troubleshoot the Website;
• understand aggregate usage and improve tutorials, blogs, and interactive tools;
• measure content and advertising performance;
• respond to messages and legitimate requests;
• detect abuse, fraud, or security incidents; and
• comply with applicable legal obligations.

10. Legal bases, where applicable

Where data-protection law requires a legal basis, processing may rely on consent, performance of a requested service, compliance with a legal obligation, or legitimate interests such as maintaining security, measuring Website performance, and improving educational content. Consent may be withdrawn through the available consent controls or by changing browser settings, without affecting processing that occurred before withdrawal.

11. Sharing and international processing

The Website owner does not sell personal information directly. Information may nevertheless be processed by service providers such as GitHub, Google, ShareThis, analytics providers, advertising partners, newsletter providers, and technical vendors. These organizations may process information in countries other than the visitor’s country of residence, subject to their own legal obligations and safeguards.

12. Data retention

Information is retained only for as long as reasonably necessary for the purposes described above, subject to the retention settings and independent policies of third-party providers. Email correspondence may be retained as needed to respond, maintain records, resolve disputes, or meet legal obligations.

13. Your privacy choices and rights

Depending on your location, you may have rights concerning access, correction, deletion, restriction, objection, portability, withdrawal of consent, or the right to lodge a complaint with a data-protection authority. Because much of the technical information is collected and controlled directly by third-party providers, some requests may need to be directed to the relevant provider.

You may also control cookies through your browser, use available consent controls, adjust Google advertising settings, or discontinue use of the Website.

14. California and other U.S. state privacy notices

Depending on applicable law and the Website’s activities, residents of certain U.S. states may have rights relating to access, deletion, correction, or opting out of certain uses of personal information. The Website does not knowingly sell personal information for monetary consideration. Advertising and analytics technologies may, however, be treated as “sharing,” “targeted advertising,” or a similar regulated activity under some state laws. Where applicable, available consent and advertising controls may be used to express these choices.

15. Children’s privacy

The Website provides general educational content and is not directed to children under 13. The Website owner does not knowingly request or collect personal information from children under 13. A parent or guardian who believes that a child has supplied personal information may contact the Website owner to request appropriate action.

16. External links and embedded content

The Website may link to or embed third-party websites, notebooks, videos, repositories, datasets, or interactive services. Those third parties operate independently and may collect information under their own privacy policies. The Website owner is not responsible for their privacy practices.

17. Security

Reasonable steps are taken to maintain the Website, but no internet transmission, hosting platform, or storage system can be guaranteed to be completely secure.

18. Changes to this policy

This Privacy Policy may be revised when the Website, its services, or applicable requirements change. The revised policy becomes effective when posted, and the “Last updated” date will be changed accordingly.
