Terms of use · 2 September 2026

Training support, not a guarantee.

These terms apply to the Itemized research prototype. By using it, you agree to use the information responsibly and in accordance with Riot Games policies and applicable law.

Purpose

Itemized presents aggregate League of Legends champion statistics and compares possible rune and item plans for education, training, and research. It does not guarantee wins, rank gains, or a correct answer for every game. League patches, player behavior, and incomplete observational evidence can make any estimate wrong.

Permitted use

You may use the public interface for personal, non-abusive analysis. You may not:

  • use Itemized to cheat, automate gameplay, or gain access to hidden session information;
  • attempt to extract credentials, bypass rate limits, disrupt the service, or reverse engineer private infrastructure;
  • resell access or use the product in a way that violates Riot's terms or developer policies;
  • misrepresent prototype outputs as proven causal conclusions.

Availability and changes

The prototype may change, pause, or remove features as patches and evidence evolve. A recommendation may be withheld when data is sparse, the patch has drifted, or supported alternatives cannot be distinguished.

Intellectual property

Riot Games owns its games, characters, artwork, data, and associated properties. Itemized owns only its independent code, analysis, and original interface materials, subject to third-party rights and licenses.

Disclaimer and limitation

The service is provided on an “as is” and “as available” basis to the extent permitted by law. Itemized disclaims implied warranties and is not liable for competitive results, lost play time, or decisions made from prototype output. Nothing here excludes liability that cannot legally be excluded.
