Cookie policy
This website does not use its own cookies for analytics, advertising, tracking or personalization purposes. However, it may display ads served by third parties (Google AdSense) that use cookies, as described below.
What are cookies?
Cookies are small files that may be stored on a user's device when visiting a website. They can be used to remember preferences, maintain sessions, measure audience or show personalized advertising, among other uses.
Cookies used directly by this website
This website does not directly install analytics, advertising or tracking cookies in the user's browser.
Third-party advertising cookies (Google AdSense)
This website may display ads served by Google AdSense. When ads are shown, Google and its advertising partners may set and read cookies (or similar technologies) in the user's browser for these purposes:
- Serving ads and limiting how many times the user sees the same ad.
- Measuring ad performance and detecting ad fraud.
- With the user's consent, personalizing ads based on previous visits to this or other websites.
Users can opt out of personalized advertising in Google's Ads Settings and at www.aboutads.info. More information about how Google uses data is available at policies.google.com/technologies/partner-sites.
In addition, some pages include Amazon affiliate links, identified as such. These cookies are only set if the user clicks the link and visits Amazon, in accordance with Amazon's cookie policy.
Technical server logs
The web hosting provider may generate technical logs necessary for the operation, security and maintenance of the site. These logs are not cookies installed by this website in the user's browser.
Google Search Console and Bing Webmaster Tools
This website may use Google Search Console and Bing Webmaster Tools to obtain aggregated data about its presence in search engines, crawl errors, impressions, clicks and indexing performance.
These tools do not, by themselves, involve this website installing analytics cookies in the visitor's browser.
Cookieless analytics (GoatCounter)
This website uses GoatCounter, a web analytics service that does not set cookies or use fingerprinting techniques to identify users. It only records aggregated, anonymous data (pages visited, approximate country, browser, referrer) to understand overall site usage. Because it does not use cookies or personally identifiable data, this service does not require the user's prior consent.
Local storage (localStorage)
This website uses the browser's local storage (localStorage) to
save a technical preference necessary for the interface to work:
- prob-theme: light/dark theme preference selected by the user.
This data is stored only on the user's device, is not transmitted to external servers and is not used for analytics or advertising purposes. Since it is technically necessary to remember the visual preference between visits, it does not require additional consent.
The site's language selector (ES/EN) is a direct link to the corresponding version of the site and does not store any preference in the browser.
Consent
While ads are displayed on this website, users in the European Economic Area, the United Kingdom and Switzerland are shown a consent notice managed by a Google-certified consent management platform (CMP) before advertising cookies are used. Users can accept, decline or configure their choice, and change or withdraw it at any time from that same notice.
Technical preferences (such as the light/dark theme) do not require consent, as they are strictly necessary for functionality requested by the user.
If other services that install non-technical cookies are added in the future (analytics, maps, embedded videos, etc.), this policy will be updated and, where necessary, the corresponding consent will be requested.
