Terms of use
Last updated 19 October 2026.
Free to use
Stronk and its statistics are free. There is no paid tier. The source code is available under the MIT licence.
No warranty
Stronk is provided as is, without warranty of any kind. The statistics are estimates from past games; they can be wrong, and they never guarantee a result. You decide what to play.
What the app changes in your client
Stronk writes its own rune page and item set, named "Stronk: champion role", and your summoner spell selection, only when you import or when you turn on import at lock-in. It never edits or deletes rune pages or item sets you made, and backs up your item sets before writing. A rune page or item set whose name starts with "Stronk: " is treated as Stronk's.
Riot Games
Stronk is a fan project and isn't endorsed by Riot Games. Your use of League of Legends remains subject to Riot Games' own terms. Stronk uses only Riot Games' official API for match data and the League client's local interface on your own computer.
Changes
These terms may change as Stronk does; the date above says when they last did.
