Advertising
On windows 1856 pixels wide or more, Google AdSense shows ads beside the content. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other sites. Google's use of advertising cookies lets it and its partners serve ads to you based on your visits to this site and other sites on the internet.
In the European Economic Area, the United Kingdom and Switzerland, Google asks for your consent before it uses cookies for personalised ads. Its message adds a "Privacy and cookie settings" link to change your answer at any time.
You can turn off personalised ads in Google's My Ad Center.
Google explains what it does with this data in How Google uses information from sites that use its services.
Visit counts
Cloudflare Web Analytics counts visits. It sets no cookie, stores nothing on your device and does not follow you from site to site. It sees the page you open, the site that sent you, your browser and device type and the country of your connection, and reports them only as totals.
Builder votes
When you change rosters in the 2027 Builder, the site sends the lineups you edited, to count them into a community roster. Your browser keeps a random ID so that one person counts once. The ID identifies nobody. To limit how many votes one connection can send per day, the server stores a code computed from your IP address and the date. Nobody can turn it back into the address or link two days together.
The votes are deleted when the poll ends.
What stays in your browser
The site keeps a few things in your browser so they survive a reload: your theme, the rosters you build, your Worlds simulator picks and settings, the notices you have already seen and the Builder's vote ID. Only the vote ever leaves your device. Clearing this site's data in your browser removes all of it.
Hosting and images
Vercel hosts the site and, like any web server, receives your IP address and browser when you load a page. Some images load straight from Riot Games, Leaguepedia (Fandom) and X, which receive the same. Google, Cloudflare, Vercel and those image hosts may process data outside the EU under their own safeguards.
Your rights
Personalised ads rely on your consent. Visit counts, votes and hosting rely on the legitimate interest in running and measuring the site. You can ask for a copy of your data, its correction or deletion, or object to its use, by writing to info@brunob.dev. You can also complain to the data protection authority of your country.
Changes
When this policy changes, the date at the top changes with it.
