Cookie policy
Last updated: November 2026. This website complies with the General Data Protection Regulation (GDPR), the Spanish Organic Law on Data Protection and Guarantee of Digital Rights (LOPDGDD) and the Spanish Data Protection Agency's (AEPD) guide on the use of cookies. The Spanish version of this policy is the legally binding one.
1. What are cookies?
A cookie is a small text file that websites store in your browser or device when you visit them. Their main purpose is to make web services work properly, remember your technical browsing preferences (such as the light or dark theme, the language or your login) and collect aggregated, anonymous metrics that help us improve the platform.
2. Types and categories of cookies used
On LitematicaWeb we classify cookies into just two clear categories:
They are essential for the website to work securely. They manage the logged-in user's session with encrypted tokens, remember your cookie consent and keep your visual theme (light/dark) and language. Under art. 22.2 of the LSSI-CE they don't require explicit consent.
They measure, statistically and fully anonymously, schematic downloads and the most visited pages to optimize performance. They are turned off by default and only turned on with your explicit consent.
