Privacy policy

The data controller is Emilio Reyna, who operates under the entropy expert brand, based in Córdoba, Argentina.

For any question about personal data: contacto@entropy.expert.

Contact form. The form asks for a name, an email address and a description of the problem to be solved; the company and the availability are optional, and the type of need, the investment range, who decides on the engagement, when the person plans to start and the contact mode they choose are recorded. They are used to answer the enquiry and, as the person agrees in the consent box on the form, to send them related material.

The website’s AI assistant. What is typed into the chat is sent to a language-model provider to produce the reply. The website does not store the text of conversations. Only if the person shows interest in an interview and leaves a phone number or an email address is the conversation saved, together with that detail, for 30 days, so that they can be answered. It is best not to include personal data in the chat unless you wish to be contacted.

Messages through WhatsApp, email or social networks. If you write through any of those channels, the message also stays on the corresponding platform, which handles it under its own policy. It is used only to reply.

Technical data. The IP address is used to limit repeated submissions of the form and of the chat. On the form it is kept for a few minutes in the server’s memory and is not stored. For the chat, only a code derived from the address (a hash) is stored, along with daily counters, not the address itself.

No sensitive data is requested.

The data is used only to answer the enquiry or the interview request and, where the person agreed on the form, to send them material related to what they asked about. Every mailing says how to opt out, which can be requested at any time. The data is not passed on to third parties.

Order of handling. A score is calculated from the form answers; it only serves to order the controller’s inbox and to decide how and when to reply. No automated decisions that affect the person are made.

Providers that process data on behalf of the controller are involved in running the website: Google (Firebase: site hosting, database and storage), Cloudflare (domain name system), Resend (delivery of contact emails) and, for the AI assistant, OpenRouter and the provider of the language model it uses.

These providers may process the data on servers located outside Argentina, including in the United States. By submitting the form with the consent box ticked, the person accepts that processing. Anyone who does not want their data processed outside the country can write to contacto@entropy.expert.

The data entered in the contact form is kept for up to 30 days from the moment the enquiry is sent, which is the period in which it is handled; after that it is deleted. If the enquiry leads to a business relationship, the necessary data moves to the controller’s client records and is kept for as long as that relationship lasts and for the periods set by the applicable rules.

The notification email the controller receives is deleted within the same period, unless the enquiry leads to a business relationship. Chat conversations that leave a contact detail are also deleted after 30 days.

Deletion can be requested at any time by writing to contacto@entropy.expert.

Every person may request access to their data, its correction, update or deletion, and may withdraw their consent, by writing to contacto@entropy.expert. Access is free of charge at intervals of no less than six months, unless a legitimate interest is shown. Requests are answered within the periods set by Law 25,326.

The Agency for Access to Public Information (Agencia de Acceso a la Información Pública), as the supervisory body of Law 25,326, is entitled to handle complaints and claims filed by people whose rights are affected by a breach of the rules in force on personal data protection.

Connections to the website use HTTPS, and access to the data received is restricted to a single authenticated administrator account.

The website is aimed at people and companies that hire professional services. It is not intended for anyone under 18.

The website links to WhatsApp, Instagram, YouTube and TikTok, among others. Those services have their own privacy and cookie policies, which the controller does not control.

This policy may be updated. The date of the latest version appears at the top of the page.
