Privacy Policy

Last updated: 14 August 2026

Wuju.gg is operated by Daguerreo Development LLC, a limited liability company in the United States ("we", "us"). This policy explains what personal information the site handles and how to exercise your rights over it. It applies to Wuju.gg and no other service.

There are no accounts, no login and no analytics or tracking pixels of our own. The personal information involved comes from routine hosting logs, from the advertising described below, and from public League of Legends match data published by Riot Games.

What the site saves on your device

The site saves the server region you pick in the header, so it remembers your choice next time. That value stays on your device, is never sent to us, and clearing your browsing data removes it. (In technical terms it is a localStorage entry, not a cookie.) Google's advertising may store its own cookies and identifiers, covered under Advertising below.

Server logs

The site is hosted on Vercel, which keeps standard request logs. Those logs contain the IP address, user agent and requested URL of each visit, which is personal information in some jurisdictions. We use them to keep the site running and to investigate abuse or outages, and we do not combine them with anything else described here. Vercel acts as our processor and retains them on a short rolling window under its own retention policy. Legal basis: our legitimate interest in operating a secure, functioning site.

What we store on our own servers

A count of how many times each replay helper has been generated: match id, region and a timestamp. No IP address, user agent, session or any other identifier is recorded with it, so these rows cannot be linked back to a person.

Player data shown on the site

Games come from Riot Games' public match and league APIs, under a Riot developer key and subject to Riot's API terms. Riot IDs are displayed because they are already public on Riot's own services. Legal basis: our legitimate interest in publishing statistics about publicly available competitive play.

Riot also issues an internal player identifier, the "puuid". It is never displayed and never sent to your browser. Match statistics are stored against a salted, truncated hash of it rather than the identifier itself. We do keep the identifier in one place, a server-side table the collector uses to know which accounts to check for new games, because Riot's API accepts only the real value there. Both the identifier and the hash are personal information and both are covered by the rights below.

If your games appear here and you would rather they did not, email wuju@daguerreo.dev with the Riot ID and region. We will remove them from the site, delete the identifiers we hold for that account, and add it to a permanent exclusion list so our collector does not pick it up again on a later ladder sweep. We also replace your Riot ID with "[removed]" in the team rosters of other players' games, so your name does not survive on someone else's page. Removals are normally done within 30 days. Copies already cached by search engines or other third parties are outside our control.

Advertising and cookies

Wuju.gg shows display advertising served by Google AdSense. Google and its partners may set cookies and use similar technologies, including advertising identifiers, to serve and measure ads. We do not receive that data and cannot identify you from it.

In the EEA, the UK and Switzerland, Google's consent message asks for your choice before any advertising cookie is set, and you can change that choice at any time from the same prompt. Elsewhere, you can manage ad personalization at adssettings.google.com or opt out of many ad networks at optout.aboutads.info. See how Google uses information from sites that use its services.

We never sell personal information for money. Serving personalized ads does count as "sharing" personal information for cross-context behavioral advertising under California law. To opt out, decline personalization in the Google prompt or turn off ad personalization at the link above; you can also email wuju@daguerreo.dev and we will confirm the opt-out. Exercising this right will not change the site for you in any other way.

Other third parties

Champion, item and rune images load directly from Riot's Data Dragon CDN, and role icons from Community Dragon. Your browser contacts those servers directly, so they can see your IP address; those requests are subject to Riot's and Community Dragon's own policies, not ours.

International transfers

The site and its data are hosted in the United States. If you visit from outside the US, the information described above is processed there. Our processors rely on the European Commission's Standard Contractual Clauses, or an equivalent transfer mechanism, for transfers out of the EEA and the UK.

Children

Wuju.gg is not directed to children and we do not knowingly collect personal information from anyone under 13 (or under 16 in the EEA and the UK). Match data is drawn from Riot's public ranked ladders, which have their own age requirements. If you believe a child's information appears here, email wuju@daguerreo.dev and we will remove it.

Your rights

If you are in the EEA or the UK, you have the right to access, correct, erase, restrict or object to our processing of your personal information, and the right to receive it in a portable form. Because our processing rests on legitimate interests rather than consent, you may object at any time and we will stop unless we have overriding grounds. You may also complain to your national data protection authority.

If you are a California resident, you have the right to know what personal information we hold, to have it deleted or corrected, and to opt out of its sharing for cross-context behavioral advertising, as described above. We will not discriminate against you for exercising any of these rights.

To exercise any of them, email wuju@daguerreo.dev. Because there are no accounts, we may ask you to demonstrate control of the Riot ID your request concerns before acting on it. We reply within 30 days.

How long we keep things

Older match statistics are deleted automatically each time the rankings are rebuilt, not on request.

How we protect this data

Player identifiers stay on the server and are never included in anything sent to your browser. The hashing secret is held only by the collector, never by the website, so the part of the system exposed to the internet cannot reverse a hash even in principle. Our database and hosting providers encrypt data in transit and at rest. Access is limited to the one person who operates the site.

No system is perfectly secure, and we would rather say so than imply otherwise. If you find a security problem here, email wuju@daguerreo.dev and we will fix it.

Changes to this policy

We update this policy when the site changes. The date at the top of the page is the last revision, and material changes are noted there. Continued use after a change means you accept the updated policy. See also our Terms of Service.
