Who we are
TrueMain is a free, non-commercial web application that provides League of Legends statistics — champion builds, runes, skill orders and performance data derived from public match data. This policy explains what data we process, why, and the choices you have. It applies to truemain.lol and its subdomains.
Information we process
Public game data. We retrieve publicly available League of Legends data through the official Riot Games API — including summoner names, Riot IDs, encrypted account identifiers (PUUIDs), match history, ranked standings and champion mastery. This data is provided by Riot Games and reflects activity that is already public in-game and on Riot's own services. We aggregate it to build per-champion and per-player statistics.
Audience measurement. We use a self-hosted analytics tool (Umami), for the sole purpose of measuring how the site is used: pages viewed, the domain of the site you came from (never the address of the page itself), your browser, operating system, device type, screen size and language, and your country, region and city derived from your IP address; your IP address itself is not stored. Campaign tracking parameters in a link (such as utm_source or ad click identifiers) are removed before anything is sent. It sets no cookie. To count unique and returning visitors, it stores a random identifier on your device (in your browser's local storage) for at most 13 months from your first visit; later visits do not extend that period, and a new identifier replaces it once it expires. This identifier is generated at random, is not linked to your IP address, your Riot account or anything else about you, is only used for our own anonymous audience statistics, and is never shared or cross-referenced with other data. If your browser does not keep it, a temporary code derived from your IP address and browser, combined with a value specific to this site that changes every month, is used instead. We do not record sessions and do not track you on other sites. The data stays on our own servers and only serves to produce statistics. You can opt out at any time with the control below, which also deletes the identifier from your device.
Your visits are counted, anonymously, in the aggregate statistics.
Accounts. TrueMain does not currently offer user accounts, logins or passwords. If we introduce account sign-in through Riot Sign-On (RSO) in the future, we will update this policy to describe the account data we receive and how it is handled before that feature goes live.
How we use data
- To compute and display champion and player statistics.
- To identify high-elo one-trick specialists ("true mains") from public ladder and match data.
- To measure aggregate site usage and improve the product.
- To operate, secure and maintain the service.
We do not sell your data, and we do not use it for advertising.
Cookies
We keep cookies to a minimum. We do not use advertising or third-party tracking cookies. Apart from the audience measurement identifier described above, which you can refuse, any storage we use is strictly necessary to operate the site (for example, remembering interface preferences, or your choice to opt out of audience measurement).
Data retention
Aggregated statistics and the public match data they are built from are retained for as long as they are useful to the service, and are pruned on a rolling basis as patches age. Audience measurement records hold no IP address, are used only to produce aggregate statistics, and are deleted automatically 25 months after they are collected; the identifier stored on your device lasts at most 13 months.
Your rights
Depending on your location (including under the EU GDPR), you may have the right to access, correct or request deletion of personal data we hold about you, and to object to certain processing. Because TrueMain surfaces public League of Legends data, you can ask us to remove your player profile and associated data from the site. To make a request, contact us at the address below.
Third parties
Game data originates from the Riot Games API and is subject to Riot's own terms and privacy practices. We host the site and its analytics on our own infrastructure. We do not share your data with third parties for their own marketing.
Children
TrueMain is not directed at children under the age required to hold a Riot Games account in their region, and we do not knowingly collect data from them.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by updating the "last updated" date at the top of this page.
