Privacy Policy
Last updated: 26 August 2026
1. Introduction
Welcome to zhuermu.com. This policy explains how your information is collected, used and protected when you visit this site.
2. Information we collect
We may collect the following:
- Usage data: pages visited, time on page, referring links, browser type, device type and IP address. Collected automatically through server logs and analytics.
- Cookies and similar technologies: used to improve your browsing experience and to serve relevant advertising. See section 5.
3. How we use it
- Operating and maintaining the site
- Analysing usage to improve content and user experience
- Serving relevant advertising through Google AdSense
- Complying with legal obligations
4. Third-party services
We use the following third parties, which may collect information about you:
- Google AdSense: serves ads on this site. Google may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalised advertising in Google Ads Settings.
- Cloudflare Web Analytics: counts visits and reports real-user performance metrics. It sets no cookies, uses no localStorage and creates no cross-site identifier; the data is aggregated.
- Giscus / GitHub: comments below an article are GitHub Discussions, embedded in an iframe. GitHub only learns who you are if you choose to sign in and post; comments are stored publicly on GitHub under GitHub's privacy policy.
- Email list provider: an address entered in the subscribe box is posted straight to the provider, used only for post notifications, and every email carries an unsubscribe link.
5. Cookies
Cookies are small text files stored on your device. We use:
- Essential cookies: required for the site to function.
- No analytics cookies: visit counting uses Cookieless Cloudflare Web Analytics. Your dark-mode preference is kept in browser localStorage (key
zm-theme) to remember the display choice, not to identify you. - Advertising cookies: used by Google AdSense to show relevant ads. These may track your browsing across sites.
- Your cookie choice: kept in browser localStorage (key
zhuermu_cookie_consent). Choosing Reject means the Google AdSense script is never added to the page — it is not loaded and then hidden, the request is never made. To choose again, clear that key and reload.
You can manage cookies in your browser settings. Note that disabling cookies may affect some functionality on this site.
6. Your rights
Depending on your jurisdiction, you may have the right to:
- Access the personal data we hold about you
- Request correction or deletion of your data
- Opt out of personalised advertising
- Withdraw consent to data processing
7. Data retention
Usage data is retained only as long as needed for the purposes described here. Analytics data is retained in aggregated, anonymised form.
8. Children's privacy
This site is not directed at children under 13, and we do not knowingly collect personal information from children.
9. Changes to this policy
This policy may be updated from time to time. Changes are posted on this page along with a revised date.
