Privacy Policy

Last updated: 6 September 2026.

Short version: there is no account, we do not want your data, and the only things that set cookies here are Google's advertising and, if you are in a region that requires a consent choice, the banner that asks you about it.

What we collect ourselves

Nothing that identifies you. There is no account, no login and no form that asks for anything about you. Builds are generated from a number in the URL — the seed — and nothing about a build is stored against a person. A build link you share reveals the build and nothing else.

Analytics

The site uses Cloudflare Web Analytics on every page. It is cookieless: it does not fingerprint you, does not track you across sites, and reports only aggregate figures such as how many people viewed a page. We cannot tell from it who you are.

Advertising

The site is funded by advertising through Google AdSense. Google and its partners set cookies and similar identifiers to serve and measure ads, and depending on your settings those may be used to personalise what you see. That is a real tracking cookie and we are not going to describe it as anything else.

If you are in the EEA, the UK or Switzerland, you will be asked for a consent choice before personalised advertising is used, and you can change or withdraw it at any time from the same control. Wherever you are, you can review and limit ad personalisation in Google's My Ad Center, and read how Google uses data from sites that use its services in their partner-sites policy.

Stored in your browser

Two things are kept in your browser's local storage, and neither is ever sent to us: champions you have chosen to exclude from rolls, and a short list of your recent and saved builds. They stay on the device you are using, are readable only by this site, and are cleared when you clear site data — or, for the build list, with the "Clear" control beside it.

Your rights

Data-protection law in the UK and EU gives you rights over personal data held about you — access, correction, deletion, and objection to processing. We hold none, so there is nothing for us to hand over or erase. Rights over what Google's advertising collects are exercised through Google, using the links above.

Third-party services

Champion, item and rune data and images come from Riot Games' Data Dragon, and are served from this site rather than fetched from Riot while you browse. The site is hosted on Cloudflare, which processes requests to it. Fonts are served by Google Fonts. Each of those has its own privacy policy.

Children

The site is not directed at children under 13, and we do not knowingly collect anything about them.

Changes

This policy will change when the site does. The date at the top is when it last did.
