1. What cookies are

Cookies are small text files that websites store in your browser. They allow the site to remember your session and preferences and improve your experience.

2. Cookies used by FacturaOk

FacturaOk uses only technical and session cookies, strictly necessary for the operation of the service. We do not use third-party cookies or advertising cookies.

First-party analytics: we measure visits without storing identifiers in cookies, localStorage or sessionStorage. The server creates a daily salted IP hash and deletes analytics data after 12 months. It cannot recognise the same browser across different days.

3. Third-party cookies

FacturaOk does not use third-party cookies. We do not include:

Google Analytics or any other third-party analytics service
Tracking pixels (Facebook, Google Ads, etc.)
Programmatic advertising services
Embedded social networks

The only external resources loaded are typographic fonts (Google Fonts and Material Icons), which are subject to Google's Privacy Policy.

4. Legal basis

As these are exclusively strictly necessary technical cookies (exempt under Article 22.2 of the LSSI-CE), no prior consent is required for their use.

Reference: Directive 2002/58/EC (ePrivacy), Article 5(3), and its transposition into Spanish law via Article 22 of Law 34/2002 (LSSI-CE).

5. How to manage local storage
