Still, discrete title queries sent over HTTPS GET to public Crossref or OpenAlex REST APIs enter standard third-party access logs\u2014meaning embargoed titles warrant DOI-only checks.<\/p>\n<\/blockquote>\n<h2>Why Architecture Matters More Than Privacy Badges<\/h2>\n<p>Traditional cloud citation checkers ask researchers to upload whole Word or PDF manuscripts onto remote servers before executing checks behind metered accounts or per-paper subscriptions. While convenient for commercial dashboards, uploading pre-publication clinical manuscripts, patent disclosures, or grant proposals creates unnecessary third-party retention risk when bibliographic validation only requires matching identifiers against public registries.<\/p>\n<p>Rather than asking authors to trust vague confidentiality prose, verifiable privacy relies on inspectable client network behavior. Anyone can verify CitePure&#8217;s architecture in under two minutes using Chrome or Firefox Developer Tools (<strong>Network<\/strong> tab) or by inspecting our standalone offline unit runner.<\/p>\n<figure class=\"cl-figure\">\n<img decoding=\"async\" src=\"\/assets\/diagrams\/tool-ui-preview.svg\" alt=\"Browser-side verification execution matching local normalized entries directly against Crossref and OpenAlex responses\" width=\"860\" height=\"460\" class=\"cl-diagram-img\" loading=\"lazy\"><figcaption class=\"cl-figure-cap\">Figure 1: Client-side pipeline splitting local parsing and scoring from discrete browser-to-registry metadata requests.<\/figcaption><\/figure>\n<h2>Exact Outbound Network Inventory (Reproducible via DevTools)<\/h2>\n<p>Open DevTools &rarr; <strong>Network<\/strong> &rarr; filter by <strong>Fetch\/XHR<\/strong>, paste a reference list into <a href=\"\/app\/\">CitePure Verification Studio<\/a>, and inspect every request emitted from the tab.

Under their standard public API logging, short bibliographic query parameters are visible to those two scholarly registries.<\/li>\n<li><strong>Practical Mitigation for Stealth \/ Embargoed R&amp;D:<\/strong> Whenever a citation&#8217;s <em>title itself<\/em> contains sensitive keywords or confidential compound names, validate by <strong>identifier only<\/strong> inside the <a href=\"\/doi-checker\/\">DOI Resolver<\/a> (where only the opaque string <code>10.xxxx\/...<\/code> travels in the URL) rather than running keyword searches.<\/li>\n<li><strong>Browser Local Storage Keys:<\/strong> CitePure writes zero tracking cookies and requires no login.
