Aligning kimura512.dev Privacy Policy With the Actual Stack

Conclusion

The privacy policy of kimura512.dev was rewritten multiple times to reconcile legal statements with actual codebase reality. Before deploying advertising tags, the priority was not drafting boilerplate for review auditors, but ensuring that contact forms, analytics pipelines, and third-party integrations matched published legal terms with exact fidelity.

1. Decoupling Portfolio Site and External Apps

Previous drafts bundled the portfolio website and standalone applications (like Suiai Map) into a single overarching definition, describing user account credentials, hashed passwords, and database models that kimura512.dev itself does not possess. The website has no user accounts, focusing purely on article reading and contact forms. The policy now explicitly delineates what happens on this domain versus what occurs within distinct mobile and web applications.

2. Verifying Third-Party Service Providers

In reality, active data flows involve only Cloudflare Workers, transactional contact delivery, Vercel Analytics, and Google AdSense. Listing unused vendors creates discrepancies with actual network behavior. The disclosure list was audited against configuration files to enumerate only actively deployed partners.

3. Apex Domain ads.txt Deployment

The public/ads.txt file is served directly from the apex domain, ensuring publisher IDs match account registration credentials. Direct HTTP checks on the live apex URL prevent subpath routing issues from blocking crawler verification.

4. Scoping Advertising Scripts to Editorial Layouts

AdSense runtime loaders are restricted to blog indexes and article layouts. Experimental interactive routes remain marked noindex and are kept completely free of advertising scripts, preventing layout interference.

Because article consumption may introduce advertising measurement cookies, Section 12 explicitly details Google AdSense cookies and personalization opt-out mechanisms.

6. Clear Scope for Contact Data

Messages submitted via Contact are routed through Workers to info@kimura512.dev. Protected by honeypots, submitted details are strictly earmarked for support correspondence.

7. Versioning and Policy Maintenance

Whenever operational dependencies shift, the "Last Updated" timestamp is refreshed in lockstep. The English translation mirrors the Japanese structure section by section, ensuring consistency across locales.

Summary

A privacy policy is not an aspirational manifesto; it is the accurate operational manual of your production stack.
