YordleDiff is a set of free League of Legends tools that run in your web browser. This policy explains — briefly — what that means for your data.
Almost nothing. YordleDiff has no accounts, no logins, and no payment system, so there is no email, password, or billing data to collect.
The only data that reaches a server is the standard web-request information every website receives:
Every tool — the champion tier list, win-condition analyzer, build optimizer, and jungle planner — runs entirely as code in your browser. The champions, team comps, and builds you enter are processed on your own device and are never uploaded to us. Closing the tab discards them.
To work, your browser loads files from:
We do not use Google Analytics, Facebook Pixel, or any analytics tracker beyond what Google AdSense itself uses to serve ads.
The contact form does not send anything to a server — it opens your own email app with your message pre-filled. We only ever receive what you choose to send us by email, and we keep those messages only as long as needed to reply.
Google AdSense and its partners set cookies on your device to serve ads, measure performance, and (where you allow it) personalize what you see. The tools themselves may also save small preferences (such as your last inputs) in your browser's local storage — that data stays on your device and is never sent anywhere.
If you are in the European Economic Area, the United Kingdom, or Switzerland, a Google-certified consent message will appear before any personalized ad cookies are set. You can consent, decline (in which case you'll see non-personalized ads), or manage individual purposes and vendors. Your choice is remembered for future visits and can be changed at any time from the small "Privacy options" link Google injects on the page.
Everywhere else, ads are served with default personalization. You can disable personalization any time at Google Ads Settings.
YordleDiff is a general-audience game tool and is not directed at children under 13. We do not knowingly collect personal data from anyone.
If this policy changes, the "Last updated" date at the top will change with it.
