Privacy Policy
Last updated: 24 June 2026
DraftSense is a champ-select companion for League of Legends. It reads your live draft and shows win-probability guidance for your role. This policy explains what data it handles and why. We collect the minimum needed to give advice during a single draft.
What we request
- For players in your own champ-select lobby: their Riot puuid, ranked tier and LP, and champion-mastery totals.
- For training the model: ranked match results, pulled in aggregate via the Riot Match-V5 API.
What we store
- Short-lived, server-side caches of (puuid to rank) and (puuid to mastery), keyed by puuid, with a short time-to-live of about ten minutes. These exist only to stay within Riot rate limits during one draft.
- Training data (match results) is stored in aggregate for fitting the model. We do not build or sell per-player profiles.
What we do not do
- We do not sell or share Riot data with third parties.
- We do not build advertising profiles from Riot data.
- We do not expose one player's data to another beyond what is already visible in their shared lobby.
- We do not automate the game client. The League client integration is read-only.
Retention and deletion
- Live rank and mastery caches expire automatically (about ten minutes).
- You can request deletion of any data tied to your account at any time by emailing us.
Identifiers and PII
Riot puuids are pseudonymous identifiers. We treat them as sensitive and never display another player's identity beyond what the in-client lobby already shows.
Compliance
DraftSense follows Riot Games' Developer Policies and the data-handling requirements for approved third-party products. All Riot data is accessed through the official Web APIs and the local client API. We do not scrape.
