Privacy policy

Last updated: 2026-09-05

This privacy policy governs the processing of personal data on the VANTAG website (vantag.dev), in compliance with Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018, of 5 December, on the Protection of Personal Data and guarantee of digital rights (LOPDGDD).

The controller is not required to appoint a Data Protection Officer (DPO) under Article 37 of the GDPR, as none of the circumstances requiring it apply.

Data we process and purpose

This website is static and does not collect personal data through forms: it has no contact form, no sign-up and no login. We process personal data only in one case:

The website uses no cookies and no analytics tools, so no browsing data is collected. See the Cookies policy.

The browser extension

The Web Vitals extension runs entirely in your browser. The metrics it measures are stored only in your own browser's local storage and are never sent to us. When it queries public APIs (Chrome UX Report, Google Public DNS, RDAP and others) it sends only the URL or domain you are analysing, governed by each provider's own privacy policy. VANTAG does not receive or store those results. Full detail in the extension's own documentation.

Legal basis for processing

Retention periods

Data provided by email will be kept for as long as necessary to handle the enquiry and, where applicable, for as long as the resulting relationship is maintained. Once concluded, the data will be kept blocked for the legally required periods to address any potential liabilities, after which it will be deleted.

Recipients of the data

Data will not be transferred to third parties, except where legally required. Data may be processed by service providers acting as processors (for example, the email or hosting provider), with whom the corresponding processing agreements have been signed in accordance with Article 28 of the GDPR.

International transfers

No international data transfers are made outside the European Economic Area. Should a provider involving such transfers be used in the future, users will be informed and the safeguards required by the GDPR will be adopted.

User rights

You may exercise the following rights at any time:

To exercise these rights, send a communication to [email protected], indicating the right you wish to exercise. The controller will handle the request within the periods established by the applicable regulations.

Complaint to the supervisory authority

If you consider that the processing of your data does not comply with the regulations, you have the right to lodge a complaint with the Spanish Data Protection Agency (AEPD), located at C/ Jorge Juan, 6, 28001, Madrid, website www.aepd.es.

Security and accuracy of the data

The controller applies appropriate technical and organisational measures to guarantee the security of personal data and prevent its alteration, loss, unauthorised processing or access. You guarantee that the data provided is truthful and undertake to communicate any changes to it.
