Last updated: 11 September 2026

2. Data, purposes and legal bases

Email enquiries

If you write to us, we may process your identification and contact data, as well as the content of your message, to respond to the enquiry, assess a possible professional relationship and maintain the necessary communications.

The legal basis will be the application of pre-contractual measures at the data subject’s request where applicable, or CSE Tech’s legitimate interest in addressing communications related to its activity.

Website operation and security

The hosting provider may process minimum technical data, such as IP address, date and time or browser information, to deliver content, maintain availability and prevent malicious use. The legal basis is the legitimate interest in operating a secure and functional website.

3. Retention

Enquiries will be retained for the time necessary to address them and, if no subsequent relationship arises, will normally be deleted within a maximum period of twelve months. Where there is a relationship or legal obligation, data may be retained for the applicable periods and subsequently kept blocked while liabilities may still be claimed.

Technical logs will be retained only for the time reasonably necessary for security, diagnostics and service continuity.

4. Recipients and transfers

We do not sell personal data. Providers supplying email, infrastructure or technology support services to CSE Tech may access data, subject to their obligations as processors. Data may also be disclosed where there is a legal obligation.

If a provider processes data outside the European Economic Area, a valid mechanism under the GDPR will be used, such as an adequacy decision or standard contractual clauses, together with the appropriate safeguards.

5. Rights

You may request access, rectification, erasure or portability of your data, and object to processing or request its restriction, by writing to info@csetech.es with the subject line “Data protection”. We may request additional information to verify your identity where necessary.

You may also lodge a complaint with the Spanish Data Protection Agency.

6. Cookies and automated decisions

This website does not use cookies or equivalent technologies for analytics, advertising or tracking. Nor does it make automated decisions or create profiles about its visitors.

7. Changes

We will update this policy when the website, processing activities or applicable regulations change. The date of the current version appears at the beginning of this page.
