Privacy Policy

This policy explains how information is handled when you visit and use this site (blog.deltastudio.space, “the Site”). If you do not agree with this policy, please stop using the Site.

Article 1 Scope

1. This policy applies to browsing all pages of the Site (Chinese and English).
2. The Site is a personal tech blog. It does not offer account registration, paid membership, or checkout. Account/order clauses do not apply.
3. Read this together with other site notices (e.g. About). For personal information, this policy controls.

Article 2 Operator and Contact

1. Site name: Feynman’s Blog.
2. Operator: Feynman (individual).
3. URL: https://blog.deltastudio.space/en/.
4. Contact: GitHub and other channels listed on the About page.

Article 3 What We Collect

1. Local preferences (not uploaded)
   Theme (light/dark) and similar UI preferences may be stored in your browser localStorage to restore settings on the next visit. They are not transmitted to this site’s server.

2. Server and host logs
   Static hosting or reverse proxies may keep standard access logs (IP, User-Agent, timestamp, request path) for security and troubleshooting. Retention follows the host’s policy.

3. Analytics (optional)
   If Google Analytics and Microsoft Clarity are enabled in site config, the site loads page-view and custom-event tracking (outbound clicks, search, code copy, scroll depth, WeChat modal) plus anonymized heatmaps/session replays. Personal data is not sold. Empty IDs disable those scripts.

4. Information you send voluntarily
   Messages via GitHub issues, email, or other external channels are used only to reply and discuss, and are not built into an on-site user profile.

Article 4 What We Do Not Collect

1. No account registration; no collection of legal name, phone, or ID numbers.
2. No payment processing on the Site.
3. No third-party ad tracking pixels; no sale of personal data.
4. No intentional collection of precise location, contacts, photos, or other sensitive device permissions.

Article 5 Cookies and Local Storage

1. The Site does not rely on advertising cookies.
2. Local storage is mainly for theme and similar preferences. You can clear or block it in browser settings; defaults will apply afterward.
3. If an analytics tool sets cookies, you may disable them in the browser. That may reduce stats quality but not block reading content.

Article 6 Third Parties and Outbound Links

1. Pages may load third-party static assets (e.g. Google Fonts) or link to GitHub and course sites. Those services have their own privacy policies.
2. After you follow an outbound link, the third party’s rules apply.

Article 7 Security and Retention

1. The Site is published as static pages. The author aims not to ship unnecessary tracking in site code.
2. Server log retention depends on the hosting provider, usually short-term for operations and security.
3. Internet transmission cannot be guaranteed absolutely secure. Do not post sensitive personal data in public comments or issues.

Article 8 Minors

The Site is for a general technical audience. Minors should read this policy with a guardian and avoid sending personal contact details to the author alone.
