Pursuant to Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018 (LOPDGDD):

Data controller

Science 4 Insights, S.L. · NIF B06972996 · Plaza Europa, 38, 11.ª A, 08902 L'Hospitalet de Llobregat (Barcelona) · info@53seconds.com

What data we process, and why

  • If you write to us (by email or through the contact form): we process your address, your name if you provide it and the content of your message, for the sole purpose of answering your enquiry and, where applicable, managing early access to the service. Legal basis: pre-contractual steps taken at your request, and your consent (Art. 6(1)(a) and (b) GDPR).
  • Technical access data: our hosting provider, with servers in the European Union, records technical connection data (such as IP addresses) in its server logs, for security and proper operation. Legal basis: legitimate interest (Art. 6(1)(f) GDPR).
  • The demo: when you open pages with live data (the demo or the home page), your browser requests the displayed data from our data-infrastructure provider, with servers in the European Union. That request is technically necessary to show you the demo and involves the processing of technical connection data. Any international transfers by providers are covered by Standard Contractual Clauses approved by the European Commission.

We do not use your data for advertising, we do not profile visitors, and we make no automated decisions affecting you.

Retention

Contact data is kept for as long as the relationship lasts or until you request its deletion, and thereafter only for statutory limitation periods.

Recipients

We do not sell or share your data with third parties. Our hosting and infrastructure providers access it as processors, under Art. 28 GDPR terms.

Your rights

You may exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to info@53seconds.com, providing proof of identity. If you consider the processing unlawful, you may lodge a complaint with the Spanish Data Protection Agency (www.aepd.es) or your local supervisory authority.

Minors

This site is aimed at professionals and is not intended for children under 14.

3. Cookie policy

This site uses no cookies. It also uses no analytics tools, tracking pixels or tracking technologies, whether first- or third-party. Fonts are served from this same site, with no calls to external font services.

The demo page stores a single display preference (the panel's light or dark mode) in your browser's local storage, at your request when you use the corresponding switch. The administration area, for internal use, likewise stores its session credential. This storage is strictly technical, does not identify the visitor, is not used for tracking, is never shared with third parties, and can be removed at any time by clearing your browsing data. Being strictly necessary for the service requested, it is exempt from the consent requirement (art. 22.2 of the Spanish LSSI-CE).

Should this change, this policy will be updated and, where required by law, prior consent will be requested through the appropriate notice.
