Privacy Policy

Welcome to MMRCheckerLoL (“we,” “us,” or “our”), available at https://mmrcheckerlol.com. This Privacy Policy explains what information is collected when you visit our website, how it is used, and the choices you have. By using this website, you agree to the practices described below.

1. Information We Do Not Collect Through Our Calculator

Our MMR calculator works entirely inside your web browser. The rank, division, LP, and win rate you enter are processed on your own device to produce an estimate. We do not send these values to our servers, we do not store them, and we do not ask for your Riot ID, summoner name, password, or any account login.

2. Information That May Be Collected Automatically

Like most websites, our hosting provider and analytics tools may automatically collect limited technical information when you visit, including:

  • Your IP address (often anonymized or truncated)
  • Browser type and version
  • Device type and operating system
  • Pages visited, time spent on pages, and referring website
  • Approximate location (country or city level)

This information is used in aggregate to understand how the site is used, fix technical problems, and improve content. It is not used to identify you personally.

3. Cookies

Cookies are small text files stored on your device. We and our third-party partners may use cookies to remember preferences, measure traffic, and (where enabled) show relevant advertising. You can block or delete cookies in your browser settings. Some parts of the site may not work as intended if cookies are disabled.

4. Analytics

We may use analytics services such as Google Analytics and Google Search Console to understand how visitors find and use the site. These services may set cookies and collect usage data as described above. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

5. Advertising

We may display advertisements through third-party networks such as Google AdSense. These networks may use cookies and similar technologies to serve ads based on your visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your browsing activity. You can manage personalized advertising through Google Ads Settings or visit aboutads.info to opt out of interest-based advertising from participating companies.

6. Third-Party Services

Our website relies on third-party services that may process limited technical data (such as your IP address) when you load a page:

  • Hosting provider: our website is hosted by Hostinger.
  • Google Fonts: used to display the typefaces on our site.
  • Google Analytics / Google AdSense: as described above, where enabled.

These providers have their own privacy policies, and we encourage you to review them.

7. Data Retention

We do not maintain a user database. Any analytics data held by third-party providers is retained according to their own retention settings, which we configure to the shortest practical period.

8. Your Rights

Depending on where you live (for example, in the European Economic Area, the United Kingdom, or California), you may have the right to access, correct, delete, or restrict the use of personal data held about you, and to object to certain processing. Because we do not collect personal information directly, most requests will relate to data held by our analytics or advertising partners. To exercise any right, contact us at the email below and we will do our best to help or point you to the right provider.

9. Children’s Privacy

This website is not directed at children under the age of 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information to us, please contact us and we will take appropriate steps to remove it.

10. External Links

Our site may link to other websites, including Riot Games resources and other League of Legends tools. We are not responsible for the content or privacy practices of those external sites, and we recommend reviewing their policies.

11. Not Affiliated With Riot Games

MMRCheckerLoL is an independent, fan-made tool. It is not affiliated with, endorsed by, or sponsored by Riot Games, Inc. League of Legends and Riot Games are trademarks or registered trademarks of Riot Games, Inc. All MMR figures shown are unofficial estimates for informational purposes only.

12. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page. We encourage you to review it periodically.
