Privacy Policy
Updated September 9, 2026
Juan Romero Domínguez ('developer', 'we', or 'our'), based in Seville, Andalusia, Spain, is firmly committed to protecting and respecting the privacy of all users globally. This Privacy Policy describes transparently, rigorously, and exhaustively how information is collected, processed, stored, and protected on our official website, thematic portals, browser extensions, and Android mobile applications.
1. Data Controller and Scope
The Data Controller is Juan Romero Domínguez. This policy covers all products designed, developed, and maintained independently:
• Websites: juanromerodominguez.dev, poema.es, calendario.gratis, adblock.network, adspy.bot, volume.audio, and foro.trading.
• Browser extensions: AdBlock Network (Local Firewall & Blocker), AdSpy Bot (Extractor & Ad Sequencer), and Volume Audio (Pro Sound Amplifier).

2. Privacy by Design and Local-First Processing Commitment
Our technical philosophy prioritizes a 100% local processing architecture on the user's device:
• QR Utilities: All barcode/QR scanning (via the device camera) and generation of codes from text, URLs, numbers, coordinates, WiFi networks, or SEPA bank transfers are processed exclusively in local memory in real-time. Images, screenshots, or read data are never transmitted to any remote server.
• Vanity Mirror & Audio: The camera preview and sound equalizer/amplifier run strictly on the terminal hardware.
• Browser Extensions: Network request interception, declarative filtering (declarativeNetRequest), DOM manipulation, and audio processing via the Web Audio API operate autonomously and sandboxed within the local browser environment.
3. Web Analytics (GA4) and Strict Exclusion in Extensions
• Websites: We use Google Analytics 4 (GA4) on our web portals to collect aggregated statistics, anonymous performance metrics, pages visited, geographical origin at country/city level, and browser type, with the sole purpose of optimizing speed and user experience.
• Browser Extensions: Browser extensions DO NOT use Google Analytics 4 or any other third-party browsing tracking service. We absolutely respect the privacy of the user's browsing habits.
4. Digital Advertising and Ad Networks
• Google AdSense: Implemented on informative and free websites (such as poema.es and calendario.gratis). AdSense may use cookies and tracking technologies to display contextual or personalized ads based on the user's consent preferences (CMP) as per the GDPR.
• Google AdMob: Used in the free versions of Android mobile applications to display in-app advertising. AdMob collects anonymous advertising identifiers (Google Advertising ID) under the operating system's consent guidelines and controls.
5. Cloud Services, Diagnostics, and Firebase (Android Apps)
In our Android applications, we integrate Google Firebase components to ensure technical stability:
• Crash Reporting (Firebase Crashlytics): Collects automatic reports and stack traces in the event of unexpected crashes or technical exceptions to identify and fix code errors.
• Diagnostics and Performance: Monitoring of latency, load times, and technical stability metrics.
• Device or Other Identifiers: Anonymous identifiers generated by the app instance (Firebase App Instance ID) necessary for configuration synchronization, diagnostics, and abuse mitigation.
6. Subscription and Payment Processing (Stripe & ExtensionPay)
Purchases of PRO licenses and premium subscriptions in browser extensions are routed through the ExtensionPay gateway and the Stripe payment platform (PCI-DSS Level 1 certified):
• The developer never has access to or stores credit card numbers, CVV, or banking credentials. Such data is managed directly by Stripe.
• For any inquiries regarding billing, receipts, or subscription management, the official channel is billing@juanromerodominguez.dev.
• In mobile apps, transactions are managed natively and independently through the Google Play Store billing system.
7. Security, Software Integrity, and Anti-Fraud Telemetry
Pursuant to Article 6.1(f) of the GDPR (Legitimate Interest in preventing cybercrime and protecting infrastructure):
Our systems have automated production telemetry and security mechanisms to verify software authenticity. Any unauthorized access attempt, source code tampering, external script injection, DOM manipulation, or bypass of the PRO verification token will trigger an automated log in our backend with technical session data (IP address, timestamp, tampering vector) to preserve service integrity and take appropriate legal action.

8. Legal Basis for Data Processing and Retention
We process data according to the following GDPR legal bases:
• User consent (Art. 6.1.a): For analytical/advertising cookies configured voluntarily.
• Contractual performance (Art. 6.1.b): For the activation and management of PRO licenses and paid features.
• Legal obligation (Art. 6.1.c): For compliance with tax, accounting, and commercial regulations.
• Legitimate interest (Art. 6.1.f): For fraud prevention, technical security, and software troubleshooting.
Diagnostic data and logs are retained only for the time strictly necessary to fulfill their technical or legal purpose.
