Arrr, keep it beside League

Afore downloading

What th' preview needs

Th' Companion be a native Windows application. It be nay a browser extension and it does nay need a Riot production API key on th' tester's PC.

OS

64-bit Windows be required. Th' release record names th' exact supported platform.

Client

Arrr, league installed locally

Display

One monitor be enough

Pick any detected display. A second monitor be useful, while th' compact overlay supports Borderless or Windowed play.

Network

Arrr, what it does

Arrr, local, visible and deliberately limited

Th' preview follows a static course prepared from champion pick. It ne'er plays League fer ye.

1

Arrr, local detection

Reads Riot's local client, Live Client, and delayed spectator interfaces through loopback addresses on yer Windows computer. Local credentials be ne'er uploaded.

2

Private clash inspect

Keeps up to 20 recent non-custom matches across game patches in separate, Windows-encrypted histories for each Riot account.

3

Static-course overlay

An optional compact window keeps pre-battle choices visible. Live performance ne'er selects or reorders advice.

4

Nay battle control

Nay injection, memory reading, automated picks, bans, pings, purchases, movement, chat, or tricks.

5

Arrr, honest spectator mode

Delayed rosters be labelled as spectator data. Lost overboard course assignments remain clearly marked as inferred.

6

Nay bundled secrets

Nay Riot API key, Discord bot token, harbour password, or private stream token be included in th' executable.

7

Between-clash reminders

Optional water, movement, meal and personal-routine prompts stay on this device. Anything due during play waits until th' clash has ended; several due checks be assembled locally and played as one shipshape recording.

Feature status, nay a competitor checklist

Every capability must clash this product's Riot record

Features advertised by another League app reveal what may be possible fer that audited product. They do nay grant VRC.LOL th' same scope automatically.

Arrr, available now

Local sailor record and client-state recognition, visible champion pick, queue-aware static builds, skill references, a fixed in-battle overlay, factual sailor-visible clash state and private post-clash inspect.

Proposed fer Riot audit

An opt-in Preview, Confirm and Apply flow fer runes and summoner spells during champion pick only. Th' sailor would see every change and active play would disable it.

Nay claimed yet

Tier-average comparisons, live doubloons-difference analysis and live gear-problem detection be nay present Companion features. Their data source, user flow and integrity boundary would need separate inspect.

Arrr, intentionally excluded

Nay foe ultimate or spell cooldown tracker, hidden-sailor resolution, automatic live purchase selection, claim victory chance, unofficial MMR, battle actions or instructions generated from changing live performance.

Present loadout remains read-only. A proposed feature be nay silently enabled, described as available, or treated as approved afore th' product record and implementation agree.

Setup and ship's bulletins

Keep yer setup or begin again

Ship's bulletins verify th' replacement first aboard, then let ye preserve local preferences or rerun welcome setup. Window recovery be always available separately.

  1. 1Keep me ship settingsTh' captain-recommended refit choice preserves scale, theme, favourites, shortcuts, overlay and reminders.

Common aboard questions

Afore ye test th' Companion

Clear th' deck answers about access, local data, displays, Windows warnings and th' refit channel.

1Is th' League Companion free?

Aye. Th' League Companion be free and be intended to remain free. There be no paid tiers, premium feature gates, advertisements, promotional pop-ups, or advertising and behavioural-tracking SDKs. Invitation codes only limit access to th' present private test; they be nay a purchase or subscription.

2Does th' Companion control League of Legends?

Nay. It does nay inject into th' battle, read process memory, automate actions, press keys, move th' cursor, buy gear, send chat, place pings, or choose champions.

3Can th' Companion apply runes and summoner spells?

Nay in th' present invited loadout. VRC.LOL be preparing an opt-in champion-pick flow that would preview a shipshape chart, require th' sailor to confirm it, and stop afore active play. Because that changes th' product from read-only to a limited League Client write, it will nay be enabled until th' feature be accurately disclosed fer Riot audit.

4Why nay copy to parchment every feature advertised by another League app?

Riot audits products and material feature changes individually. Another app advertising a feature does nay transfer its approval, implementation captain's particulars, or data permissions to VRC.LOL. Th' present loadout therefore includes only th' behavior described fer this product and excludes foe cooldown tracking and automatic live coaching.

5Where does clash captain's log stay?

Eligible match reviews stay on the Windows PC and can span game patches. Histories are encrypted for the Windows account and separated by Riot account.

6Arrr, do I need a second monitor?

Nay. A second monitor be convenient, but optional. Th' Companion can use any detected display and includes a compact overlay fer Borderless or Windowed League.

7Why can Windows SmartScreen reveal a warning?

Th' present preview be nay Authenticode signed. Invited testers should haul aboard only from VRC.LOL and compare th' shipshape SHA-256 checksum shown on this chart.

8What happens when an refit fails?

Th' existing executable be kept intact. A replacement be only applied after th' guarded release channel, file size, and SHA-256 checksum have been verified.

9Can I keep me ship settings after an refit?

Aye. Keep me ship settings be picked by default. Set sail fresh reruns welcome setup and resets preferences, while sailor record-separated encrypted clash captain's log remains untouched.

10How do I recover a lost overboard Companion window?

Use th' notification-area menu or press Ctrl + Alt + Shift + Home port while th' Companion be running. An optional setting can repeat seaworthy primary-display placement on every startup until disabled.

11Does th' app contain a Riot API key?

Nay. Th' executable contains no Riot API key, Discord bot token, harbour password, or private stream credential.

12Arrr, what does “local” mean here?

Th' League and battle clients expose HTTPS services on th' loopback address 127.0.0.1. That address points back aboard to th' same PC. Th' Companion reads those local services; th' League lockfile password be used only fer authenticated loopback requests and be ne'er sent to VRC.LOL or shown to th' web interface.

13Can VRC.LOL guarantee Riot will ne'er object to th' Companion?

Nay third party can make that guarantee. Riot requires products using League Client interfaces to be registered and audited, and describes th' League Client API as unsupported and subject to change. Th' preview be deliberately read-only, discloses its interfaces, avoids hidden ship's intelligence and automation, and remains a limited test while Riot inspect be pending.

14What be included in Copy to parchment fer yer crew diagnostics?

Th' copied summary contains th' Companion loadout, League connection and phase, queue, mode, sea chart, assigned role, patch, spectator and custom-battle flags, local captain's log count, stream-publishing state, and inspect time. It omits sailor names, Riot IDs, clash captain's particulars, file paths, access codes, and credentials.
