Smurf Tracker

Every League account you own in one place: rank, LP history, logins, notes. It runs in your browser with nothing to install, no sign-up and no server.

What it does

• Ranks without the busywork. One click checks every account. Each card shows the tier, LP, win rate and level, plus an LP chart that draws the ladder as bands, so a promotion looks like one. Past seasons, flex rank and your champions sit under Details.
• Tells you what to play. Play next picks the account that needs a game: one about to decay first, otherwise the one you have left longest. Decay risk estimates how many days a Diamond+ account has banked from the games seen between checks. This week sums up the last seven days, and Needs refresh counts the accounts whose rank is old. With your worker, decay alerts reach your Discord even while the app is closed.
• Logins kept safe. Username, password and email per account, hidden until you ask. Set a master password and everything is encrypted (AES-256, 600 000 PBKDF2 rounds), with auto-lock, and unlock with Face ID, a fingerprint or Windows Hello instead of typing it. Copy username, then password fills a login screen in two pastes, and copied passwords clear after 30 seconds. A Password check-up (Settings → Security) finds passwords used on more than one account, weak ones and, when you ask, ones that appear in known data leaks, without sending the passwords.
• Three layouts, your look. Cards to browse, a list to work through a big vault, or a wall of rank crests to see the whole collection at once. Pick a theme (Hextech, Shadow Isles, Noxus, Piltover, Freljord, Ionia, Void, or one that follows your best rank), choose what each card shows, and set the effects and text size. Each card can carry champion art: its most-played champion by default, or any champion and skin you pick with Card art….
• Notes with fields. Honor level, skins, champions owned, Blue Essence, 2-step verification and penalties, plus fields of your own (where an account came from, what it cost). Every card shows them the same way, and search finds them.
• Share a snapshot. A read-only page of your ranks in one link, to send a friend: best rank, games, win rate, then each account with its art and LP line. You choose which accounts and whether Riot IDs are shown. Logins, emails and notes are never in it, and nothing is uploaded: the link itself is the page.
• Streamer mode. Press H and Riot IDs, logins, emails and notes are blurred, so you can stream or share your screen.
• Finds things fast. Search names, tags, notes, skins and ranks, or combine filters like >diamond is:stale, region:euw, is:decay, champ:yasuo or role:mid. Accounts still levelling show how far they are from 30, and is:ready lists the ones that can play ranked.
• Backups and sync. Export a plain or encrypted backup, add many accounts at once (a list of Name#TAGs, an op.gg multi-search link or the lobby chat), or sync phone and PC through your own worker. Only the encrypted vault is uploaded. A new split? New season moves every rank into Past seasons in one go.

A shared snapshot, as a friend sees it:

Get started

1. Open the app. Want to look around first? Preview with example data shows it full, and saves nothing.
2. + Add account, then paste a Riot ID like Faker#KR1 into the name field: it splits itself.
3. Follow Get set up: check ranks, set a master password, back up.
4. Install it (your browser's Install app, or Add to Home Screen on iPhone). It opens like an app and works offline. On iPhone this also stops Safari deleting your data after 7 days away.

Your data lives in this browser only. Read SECURITY.md for exactly what is stored, what is encrypted, and what ever leaves your device. In short, keep a backup.

Optional: your own worker

Out of the box, rank checks read op.gg through free public proxies. That works most of the time, but the proxies are other people's servers and can be slow or down. Your own Cloudflare Worker is free, takes about five minutes, and gets you:

• faster, more reliable checks, plus the champion table and the dates your LP was actually reached;
• device sync (the encrypted vault, nothing else);
• with a Riot API key: ranks straight from Riot, accounts that keep their history when renamed, your last 5 ranked games, win streaks and roles, and champion mastery under Details;
• decay alerts on Discord (Settings → Alerts), checked once a day even when the app is closed.

1. Click Deploy to Cloudflare and sign in (a free account is enough).
2. Cloudflare copies this repo into your GitHub account. Keep that copy private: it is yours alone, as the terms allow.
3. It asks for RIOT_API_KEY. Paste a key if you have one (see below), or leave it empty for now.
4. When it finishes, copy the https://….workers.dev address.
5. In the app: Settings → Backend URL, paste it, Save. The line under the field says what your worker has: the Riot key, and sync storage.

1. dash.cloudflare.com → Workers & Pages → Create → Create Worker → name it → Deploy.
2. Edit code → paste the whole of cloudflare-worker.js → Deploy.
3. For sync and alerts: Storage & Databases → KV → create a namespace, then in the worker Settings → Bindings → Add → KV namespace, variable name VAULT. For alerts, also add a Cron Trigger 17 9 * * * under Settings → Triggers.
4. Copy the workers.dev address into Settings → Backend URL in the app.

A Riot API key

With a key, your worker asks Riot's own API. Without one, it reads op.gg.

1. Sign in at developer.riotgames.com with your Riot account and accept the developer terms.
2. Your dashboard shows a Development API Key straight away. It works at once but expires every 24 hours, so it is for trying things out.
3. For a key that lasts, choose Register Product → Personal API Key and describe the tool: something like "A personal tracker for my own League accounts: it reads their rank and recent ranked games. Only I use it." Riot reviews the request, which can take a while.
4. Put the key in your worker: Cloudflare dashboard → Workers & Pages → your worker → Settings → Variables and Secrets → Add. Choose type Secret, name it RIOT_API_KEY, paste the key and Deploy.
5. Reopen Settings in the app. It should say Riot API key: set.

A personal key allows 100 requests every 2 minutes, roughly 40 accounts. A bigger Check all gets the rest from op.gg, so nothing fails. If the key expires or is wrong, the app says so once and carries on with op.gg.

Device sync

1. Set a master password; only the encrypted vault is ever uploaded.
2. With the Backend URL saved, Generate a sync token in Settings.
3. On each device, use the same token and the same master password, then Push to cloud and Pull from cloud. The newest write wins, and you are warned if the other side is newer.

Keep every synced device on the latest version: since 2.1 the vault uses stronger encryption, which older versions cannot open. Reloading the page updates it.

Decay alerts on Discord

1. In Discord: Server Settings → Integrations → Webhooks → New Webhook, pick the channel, Copy Webhook URL.
2. In the app: Settings → Alerts, paste it, tick Decay alerts on Discord, Save.

Once a day your worker re-reads your Diamond+ accounts and posts when one is about to decay, or has started to: once per change, not every day. For this it keeps a short list on your worker: those accounts' Riot IDs, labels and decay estimates, never logins.

Deployed your worker before 2.2? It needs the new code and its daily trigger. Click Deploy to Cloudflare again, or paste the new cloudflare-worker.js into your worker and add a Cron Trigger 17 9 * * * under its Settings → Triggers. The app says so if your worker is too old.

Development

index.html is the whole app: one file, no build step. The test suite in tests/ boots that exact file in jsdom with Node's built-in runner, so nothing is copied into the tests and a red test means the shipped page is wrong. It covers the op.gg parsers against real markup, the ladder maths, escaping, the vault encryption, the worker, and a regression test for every bug fixed so far.

cd tests
npm install
npm test

Releasing. Bump APP_VERSION, add its entry to APP_CHANGELOG (the in-app toast shows the first two lines), and bump the cache name in sw.js. When the tests pass on main, a GitHub Release is published automatically, with that changelog entry as its notes.
