📵 Recording, intercepting, or accessing someone’s phone calls or messages without consent is illegal.

• This includes secretly listening to calls, reading WhatsApp/SMS, or hacking into devices.
• If a person is monitoring your phone use without permission, they are violating your privacy and fundamental rights.

📌 Legal Basis in Spain

✅ Intercepting private communications (calls, messages, emails) without consent.
✅ Recording conversations without consent when you are not a participant.

✅ Installing spyware or surveillance software on a phone.

📌 Penalties

2. What to Do If This Is Happening to You

✅ Secure Your Devices:
