Data You Actively Submit

Comments

This blog does not currently enable a comment feature. If a comment system (such as Giscus, Disqus, etc.) is added in the future, the specific provider and data collection practices will be updated here.

Contact Forms

This blog does not currently use any contact form. If you send me an email directly through the email link on the page, the following terms apply:

• I will receive your email address, name (if any), and the content of your message. This data is used solely to respond to your inquiry and will not be used for marketing or shared with third parties.
• My personal mailbox may be subject to hacking attacks, and I cannot guarantee the absolute security of email content. In the event of a breach, I will do my best to notify you and take remedial measures.
• The legal basis for me receiving your email data is your consent (sending an email voluntarily constitutes consent) and my legitimate interest (to respond to your inquiry).
• If your email itself contains sensitive information (such as personal identity information), please handle it yourself before sending.

Cookie Policy

This site does not set any cookies by itself. However, third-party services we use (such as Cloudflare) may set necessary cookies on your device, as detailed in the ‘Third-Party Services’ section below.

Local Data

When you switch languages or select a theme on this site, your browser automatically saves the corresponding settings. These settings are stored locally and do not contain personally identifiable information, so they can be used on your next visit.

Third-Party Services

Cloudflare

This site is deployed on Cloudflare and uses Cloudflare’s domain services.

Cloudflare is a company headquartered in the United States, and your data may be transferred to the US. Cloudflare is certified under the EU-US Data Privacy Framework and provides Standard Contractual Clauses (SCCs) as a legal safeguard for data transfers.

When you visit this site, Cloudflare may affect you in the following ways:

• Cloudflare may automatically collect standard server logs (such as IP address, request time, User-Agent, referring page, browser language, etc.) for network optimization, security protection, and attack analysis.
• Cloudflare may set necessary security cookies (such as __cf_bm, cf_clearance), which usually do not contain personally identifiable information.
• Cloudflare typically retains standard log data for 24 to 72 hours.

Cloudflare’s legal basis for such actions is its Legitimate Interest, namely providing you with a safe and stable website access service. In addition, you should be aware that:

• Cloudflare’s services are not static, and this site’s privacy policy may not be updated in a timely manner.
• I cannot access the raw logs collected by Cloudflare and am not aware of Cloudflare’s complete service policies.
• Under the General Data Protection Regulation (GDPR), you also have the right to restriction of processing, data portability, and the right to lodge a complaint with a data protection supervisory authority.

Cloudflare’s privacy policy can be found at: https://www.cloudflare.com/privacypolicy/

There are currently no other third-party services (no ads, no social media plugins, no external fonts). The content of this blog is public and will therefore be automatically crawled and indexed by search engine crawlers such as Baidu, Google, and Bing, which is normal website indexing behavior. I cannot control how these crawlers collect, store, or display your information. If you do not want certain content to be indexed, please contact me by email.

If you would like to learn more about the technologies and services used on this site, please visit the About This Site page.

Data Security and Disclaimer

• Since this website is hosted by Cloudflare, I cannot guarantee absolute data security.
• In the event of a data breach caused by platform vulnerabilities or external attacks, I will do my best to notify affected users and cooperate in handling the matter, but I do not assume responsibility beyond reasonable control.
• I guarantee that I will not sell, rent, or exchange your personal data.

Your Rights

Under applicable privacy laws, you have the right to:

• Ask which data I hold about you (usually only the email records you voluntarily send).
• Request deletion of email content related to you. I will make reasonable efforts to fulfill your deletion request. However, due to technical reasons (such as email backup systems or limitations of third-party email providers), I may not be able to ensure that data is completely removed from all storage media. In such cases, I will clearly inform you of this situation and explain the measures we have taken to limit further use of your data.
• If you have provided data to me based on ‘consent’ (such as sending an email), you have the right to withdraw your consent at any time by contacting me. Withdrawal will not affect the lawfulness of the data processing carried out before the withdrawal based on your consent.
• Refuse or clear cookies through your browser settings.
• Report violations by third-party services to me.

Please exercise your rights by contacting privacy@haojun0823.xyz; I will respond within 30 days.

Policy Updates

If there are any significant changes to this page (such as adding a comment system or changing analytics tools), it will be announced as a pinned notice in News. Minor wording adjustments will not be separately announced. You can always check the latest version on this page.

Final reminder: If you encounter any unexpected ads, pop-ups, or malicious content on this website, it is most likely due to tampering with your local network, browser plugins, or DNS resolution. You can report it to me via the email above to help troubleshoot.
