Privacy Policy

Welcome to Data Machi ("this website," at www.data-machi.com). We take your privacy seriously. This policy explains what information we collect when you use this website, how we use it, and how you can control your own data. Using this website means you've read and agreed to this policy.

1. What Information We Collect

This website is a content browsing page with no member registration, online payment, or form-collection features — we never actively ask you for your name, email, or other personal information. We collect anonymous usage data through Google Analytics (GA4), including but not limited to:

• Pages visited, time spent, and click behavior
• Technical information such as device type, browser, and operating system
• Approximate geographic location (inferred from IP address, not precise to a personal address)
• Traffic source (e.g. via search engines, social platforms, or direct URL entry)

This information is aggregated and statistical in nature; we never link it to your real identity.

2. Use of Cookies and Analytics Tools

This website uses cookies to support Google Analytics. The first time you visit, you'll see a cookie consent banner — tracking code only starts running after you click "Accept"; if you click "Decline," this website will not load any analytics cookies. You can also clear cookies or block tracking at any time through your browser settings, which won't affect any other functionality on this website.

3. How We Use This Information

The sole purpose of collecting the information above is to understand how visitors use this website, in order to:

• Understand which content is most helpful to readers, as a basis for future content planning
• Troubleshoot website performance or usability issues
• Track overall traffic trends

We never use this data for ad targeting, resell it to third parties, or use it for any purpose beyond those stated above.

4. Third-Party Services

This website uses the following third-party services, each with its own independent privacy policy:

• Google Analytics：Provides anonymous traffic analytics — see the Google Privacy Policy。
• Mintlify：This website's "Start Reading" link leads to documentation content hosted by Mintlify (www.data-machi.com/docs); that content is subject to Mintlify's own privacy and data-handling practices.

5. Data Retention and Security

We do not store any personally identifiable data on our own servers. Statistical data collected through Google Analytics is retained and accessed according to Google Analytics' default platform policies. We take reasonable technical measures (such as HTTPS encryption) to keep the connection between you and this website secure.

6. Your Choices and Rights

You can, at any time:

• Choose "Decline" in the cookie consent banner, or clear your browser's stored consent record afterward to change your choice
• Block cookies through your browser's privacy settings, or browse in private/incognito mode
• Install browser extensions (such as a Google Analytics opt-out add-on) to further restrict tracking
• Contact us via the details below with any questions about this policy

7. Children's Privacy

This website's content is aimed primarily at enterprise and workplace readers, is not designed for children, and we do not knowingly collect personal data from children under 13.

8. Policy Revisions

We may update this Privacy Policy from time to time to reflect changes in the website's functionality or applicable regulations. Any revision will update the "Last updated" date on this page — we recommend checking back periodically. We'll provide prominent notice on the website for any material change.
