Privacy Policy

Effective date: 2026-09-19

KD AI Hub ("this site") respects and protects the privacy of every visitor. This policy explains what data the site handles, how it is used, and what control you have over it.

1. What this site is​

This site is a public site for educational content. It requires no registration, no sign-in, and offers no user accounts.

2. Data we do not collect​

This site does not actively collect any of the following:

  • Personally identifying information such as your name, phone number or address
  • Financial, payment or health information
  • Account passwords or any credentials
  • Anything you type into third-party AI tools

There is no form anywhere on this site that asks you for the data above.

3. Data we may process​

3.1 Site analytics​

This site may use Google Analytics (via Google Tag Manager) to understand overall usage, for example:

  • Which pages are visited and how long people stay
  • Referring sites and rough geographic region (country / city level)
  • Device type and browser

This data is presented in aggregate and used to improve the quality of the content. It is not used to identify individual visitors.

3.2 Browser local storage​

Site search and display preferences may use your browser's localStorage. That data lives only in your own browser and is never sent to us or to any third party. Clearing your browser data removes it.

4. Third-party services​

This site is hosted on GitHub Pages and may link out to third-party sites (for example the official sites of various AI tools, or social platforms). Once you click through and leave this site, that site's privacy policy applies instead of this one. We have no control over how third parties handle your data.

Third-party services used by this site may include:

  • GitHub Pages — site hosting
  • Google Analytics / Google Tag Manager — traffic analytics
  • Google Fonts — font loading

5. Cookies​

This site does not set functional cookies of its own. Analytics services may set cookies for statistical purposes; you can block or delete them in your browser settings without affecting your ability to read the content here.

6. Children's privacy​

The content on this site is suitable for a general audience, and we do not actively collect personal data from visitors of any age.

7. Important: what you type into AI tools​

This site introduces many third-party AI tools. Please note in particular:

  • Anything you enter into ChatGPT, Claude, Gemini and similar tools is handled by that provider under its own policy and has nothing to do with this site
  • Some services may use your conversations to improve their models; please check and adjust that service's settings yourself
  • Never enter personal data, trade secrets or unpublished information into any AI tool

For detailed recommendations, see Safety, Privacy and Judgment.

8. Policy updates​

If this policy changes, this page will be updated directly and the effective date adjusted.
