You can check if public agencies like the Police, DGT, or Hacienda have accessed your personal data through a little-known feature in Mi Carpeta Ciudadana, the Spanish government's citizen portal. This tool lets you see a record of every time an administration has consulted your information, giving you greater control over your privacy.
What Is Mi Carpeta Ciudadana and Why It Matters
Mi Carpeta Ciudadana is an official application and website that centralizes your interactions with Spanish public administrations. It provides access to your documents, notifications, and data held by various agencies. Among its many features, there's a transparency section that logs access to your personal data by other organizations.
This is important because your personal data is frequently shared between public entities for administrative purposes. Knowing who has accessed it can help you detect errors, unauthorized access, or simply understand how your information flows within the government.

Step-by-Step Guide to Checking Data Access
To find out if an agency has investigated your personal data, follow these steps:

- Access Mi Carpeta Ciudadana: Download the app from Google Play or the App Store, or visit the official website.
- Log in: Use your preferred authentication method: Cl@ve, electronic DNI, PIN key, or permanent key.
- Navigate to Mi Carpeta: Once logged in, tap on the 'Mi Carpeta' section in the bottom bar.
- Go to Transparencia: In the 'Mis Datos' tab, select the 'Transparencia' option.
- Check exchanges: Click on 'Mis intercambios entre administraciones' and then choose 'Entre Organismos' to see which entities have accessed your data.
This will bring up the 'Consultas entre Organismos' screen, where you'll find a detailed list of accesses, including the date, the requesting body, and the purpose.

Which Agencies Can Access Your Data?
Various public administrations may access your personal data, including:

- Police: For security and investigation purposes.
- DGT (Dirección General de Tráfico): For driving-related matters.
- Hacienda (Tax Agency): For tax administration and verification.
- Notaries: For legal transactions and property records.
- Other agencies: Such as Social Security, local councils, and regional administrations.
Each access is typically justified by a legal or administrative procedure. The transparency log helps you verify that these accesses are legitimate.
