Privacy Policy

Last updated: 2026-08-04

This page explains how "Practical Guide" (shiyongzhinan.cn, hereinafter "this site") handles visitor information. Using this site means you understand and accept this policy.

1. Information we collect

This is a content-reading site. We do not offer registration, login, or comments, so we do not actively collect personal identity information such as your name, phone number, or ID.

The only information that may be recorded falls into two categories:

Server access logs: like most websites, the server automatically records access time, requested page, referrer, browser and OS type, and a processed IP address. This is used for troubleshooting and aggregate trend statistics.
Information you provide voluntarily: if you contact us by email, we see your address and message. This is used only to reply to your inquiry, not for marketing, and is not shared with third parties.

2. Use of cookies

Cookies are small text files a site stores in your browser. This site and its third-party providers may use cookies to:

Maintain basic page experience;
Measure aggregate visit trends (not for identifying individuals);
Let ad providers serve and measure ads.

You can view, manage, or clear cookies in your browser settings, and you can refuse cookies. Disabling cookies does not affect reading articles.

3. Third-party ads and vendor cookies

This site may show ads from third-party providers such as Google AdSense. About such ads you should know:

As a third party, Google uses cookies to serve ads on this site.
Google uses advertising cookies so it and its partners can show relevant ads based on your visits to this site or other sites.
Users can visit Google Ad Settings (www.google.com/settings/ads) to opt out of personalized ads. Or visit aboutads.info to opt out of third-party cookies used for personalized ads.
Cookies from third-party ad providers not working with Google are governed by their own privacy policies, which this site cannot control.

We cannot access or control the cookies used by third-party ad providers.

4. Analytics

If this site enables analytics (e.g., Google Analytics), it collects anonymous visit data via cookies to understand which content is popular and improve topics. Data is presented in aggregate and not used to identify individuals.

5. External links

Software mentioned in our articles appears as plain text. We do not set affiliate, referral, or promotional redirects. If a page (such as this policy page) contains an explanatory external address, those sites have their own privacy policies and we are not responsible for their content or practices.

6. Children's privacy

This site is for general adult readers, not children under 13, and we do not knowingly collect children's personal information. If you believe a child has provided us personal information, tell us via the contact page and we will delete it promptly.

7. Data retention and security

Server access logs are retained on a routine operations cycle and overwritten when expired. Email correspondence is kept in the mailbox after the inquiry is resolved and is not reused. We take reasonable technical measures to protect data, but understand that no internet transmission is absolutely secure.

8. Your rights

You may at any time:

Clear this site's cookies in your browser;
Opt out of personalized ads via the links above;
Request deletion of email information we hold about you.

9. Policy updates

If this policy changes, we update the "Last updated" date at the top of this page. Significant changes are announced on the homepage.
