What data we handle
There are no accounts or forms, and we use no analytics and no first- or third-party cookies.
To serve the pages, our hosting provider (Vercel Inc.) processes the technical data strictly needed for each visit, such as IP address and browser, in short-lived security logs.
What is stored in your browser
The simulator stores your simulation, and the site stores preferences such as your region, in your browser's local storage (localStorage). They never leave your device, do not identify you and can be deleted from your browser settings.
When you share a simulation, it travels in the part of the link after “#”, which browsers do not send to any server.
External links
We link to sources and channels such as LoL Esports, Liquipedia, Wikipedia, Twitch or YouTube. When you open them, their own privacy policies apply.
Google AdSense ads and cookies
The site currently shows no ads and uses no cookies. If we turn on Google AdSense ads, we will update this section beforehand and the following will apply:
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on those visits.
You can opt out of personalized advertising in Google's Ads Settings (adssettings.google.com) and learn more at policies.google.com/technologies/ads.
In the European Economic Area, the United Kingdom and Switzerland we will ask for your consent through a Google-certified consent management platform before using cookies, and you will be able to change your choice at any time.
Your rights
Since we keep no personal data about you, there is usually nothing to access or delete. You can still exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to contacto@leagueworlds.com, and complain to a data protection authority (in Spain, the AEPD).
