Política de privacidad de SEO Panel

1. Resumen

SEO Panel is a free, open-source Google Chrome extension designed for web developers, technical SEOs, and content creators. It provides real-time on-page SEO audits, heading structure validation, Core Web Vitals metrics, and structured data analysis directly within Chrome’s native side panel.

2. Qué datos se procesan y dónde

SEO Panel operates strictly on a local-first paradigm. It processes only the minimum data required to calculate SEO metrics on demand for the web page currently loaded in your active tab.

Análisis local

When you open the side panel on an active browser tab, the extension inspects the tab’s Document Object Model (DOM) locally using Chrome’s content script APIs:

• Meta Tags & SEO Signals: Reads title tags, meta descriptions, robots directives (noindex, nofollow), canonical URLs, Open Graph, Twitter Cards, and hreflang annotations.
• Heading Hierarchy: Scans heading tags (<h1> through <h6> to validate structural ordering and flag missing or empty elements.
• Links & HTTP Diagnostics: Analyzes internal and external hyperlinks, anchor texts, and link relationship attributes (rel="nofollow", rel="sponsored"). When you explicitly request broken link checks, status requests are initiated directly from your browser with no intermediate server.
• Core Web Vitals: Retrieves real-time performance indicators (such as Largest Contentful Paint [LCP], Interaction to Next Paint [INP], and Cumulative Layout Shift [CLS]) recorded locally in your browser session via the native PerformanceObserver API.
• Structured Data: Extracts JSON-LD scripts and Microdata attributes for in-browser syntax and schema validation.

Almacenamiento local

SEO Panel utilizes Chrome's sandboxed local storage API (chrome.storage.local). This data remains strictly on your machine and is never synced across devices unless enabled by your personal Chrome browser profile sync settings:

• User configuration: Preferences such as active panel tabs, visual theme, custom score thresholds, and UI display settings.
• Audit history (optional): If you choose to keep an audit history, timestamps and extracted metrics for audited pages are saved locally to allow comparison over time. You can disable history recording or clear your stored history at any time from the extension's settings tab.

3. Permisos de Chrome usados y justificaciones

In compliance with the Chrome Web Store Developer Program Policies, SEO Panel requests only the minimum set of permissions strictly necessary to execute its declared core features:

4. Servicios de terceros y código remoto

SEO Panel adheres to modern Chrome Manifest V3 architectural guidelines:

• No remote code execution: The extension does not load dynamic scripts from remote CDNs or external web endpoints. All code, templates, and libraries are bundled locally within the extension package at compile time.
• No third-party analytics: We do not integrate third-party telemetry, tracking pixels, cookies, or monitoring libraries (such as Google Analytics, Mixpanel, or Sentry).
• Credentialless user requests: When verifying external link health, status requests are issued by your browser without sending cookies, headers with personal authentication, or sensitive credentials.

5. Cambios a esta política

We may update this Privacy Policy from time to time to reflect modifications in browser extension capabilities, updates to Google Chrome policies, or the addition of new features. Any modifications will be posted to this page along with an updated "Last Updated" revision date at the top of the policy.

Because SEO Panel does not collect email addresses or contact details, we encourage users to review this page or the open-source repository change log when installing version updates.
