Privacy policy
One of the most important details to know whether or not you should leave your personal data on a website or blog like this one is precisely confirming if it has a privacy policy and knowing what they explain in it.

And not only because it is a mandatory legal requirement, but because it is the best way to be transparent and honest with users.

In this privacy policy I am going to explain you all the conditions I assume when capturing, managing and storing the data of the Users who relate to this blog and who provide me with their personal data, and how I use them.

First of all, I want to make explicitly clear that does not collect personal data beyond those provided by the users themselves when filling out the contact form.

Minors under 14 years old who want to contact me will need an explicit authorization from their parents or legal guardians which must be clearly attached to the content of the message.

In this website I have tried to create a professional environment related to digital marketing. Even so, it is a professional environment so a minor under 14 years old should not access without the consent of an adult.

In addition, I never ask for more information than necessary. Another thing to keep in mind is that I maintain extreme confidentiality of all data, names, emails, mails, phone numbers, emails, etc. that I may receive. I have an airtight data policy so any data that comes to me will remain confidential and will not give access to any third party. In case it was not clear, there is no possible scenario in which user data could be sold or given to third parties, ever.

What data is “necessary”. I understand as “necessary” data and that I “need” all the data related to be able to maintain a contact via mail, telephone or face to face and if there is finally a commercial relationship, the fiscal data of invoicing. This really means that the only data that receive, request and want are the name and surname (or surnames) of the contact, mail and billing information.

All these data are given to me by you. My only method of obtaining data is through you. The only way that I have and that is available on this website for me to obtain your data is when you decide to write me. At that time I get your name (or whatever name you decide to put) your email and message.Once we establish a relationship by email on a voluntary basis and if you wish to do so, you will provide me with the data that you consider in good faith.

What I plan to do with the data I receive
The only way I get data is through 2 processes: you writing me an email and cookies. As you will see there is no form to fill in the data beyond asking for your name and email address. Another possibility to collect some data is if you leave a message on the blog. Even so, all the data I collect are intended to:

– Respond to your emails, because if I get your email address and name is because you have decided to contact me either by requesting information or for any other issue.

– The possibility of entering them in a database of customers and users.

I must warn you that this Privacy Policy may vary depending on legislative requirements or self-regulation, so I advise you to visit it periodically. And it will always be applicable when you as a User decide to fill in any of the contact or subscription forms where personal data (name, email, etc.) are collected.
