Privacy Policy

Last updated: August 2026

The LoL A–Z Challenge Tracker (“the app”) helps you track your progress in the League of Legends A–Z challenge. This policy explains what data the app handles and why. By using the app, you agree to this policy.

Information the app handles

Account info — if you sign in with Google, we receive your name, email address, profile photo, and Google account ID (via Firebase Authentication). This is used only to identify your account and sync your data.
Your challenge data — the runs you create and their contents: champion progress, per-game win/loss logs, ratings, notes, and settings.
Riot ID & imported matches — if you use the import feature, the Riot ID you enter (game name, tag, region) and the match data returned by Riot for those games (champion played, win/loss, date). This is stored with your run.
Local storage — when you are not signed in, your data is kept only in your own browser’s local storage and is not sent anywhere.

How the data is used

Your data is used solely to provide the tracker: showing your progress, saving it, and (when signed in) syncing it across your devices. We do not sell your data or use it for advertising or profiling.

Third-party services

Firebase (Google) — provides sign-in and cloud storage (Firestore). Your signed-in data is stored on Google Cloud infrastructure and governed by Google’s Privacy Policy.
Riot Games API — when you import games, the app’s server requests your match history from Riot on your behalf. Your Riot API usage is subject to Riot’s policies.

Data storage and security

Signed-in data is stored in Firestore and readable/writable only by your own authenticated account (enforced by security rules). No system is perfectly secure, but access is scoped to you.

Your choices and data deletion

You can clear a single run’s progress at any time with “Reset run.”
You can sign out to stop cloud sync and use the app locally only.
Delete my data — when signed in, the “Delete my data” button (next to Sign out) permanently and immediately erases all of your runs and stored data from the cloud, and signs you out. This is fully self-service; no request or waiting period is needed.

Cookies and local storage

The app uses browser local storage to save your progress and standard authentication tokens to keep you signed in. It does not use third-party advertising or tracking cookies.

We use Vercel Web Analytics for aggregate, anonymous page-view counts (which pages are visited, roughly how many visitors). It is cookieless and does not collect personal information or track you across sites.

Children’s privacy

The app is not directed at children under 13 and does not knowingly collect their personal information.

Changes to this policy

This policy may be updated over time. Material changes will be reflected by updating the date at the top of this page.

Managing your data

Because you can view and erase all of your data yourself within the app — “Reset run” for a single run, and “Delete my data” to remove everything — there is no separate data-request process. Deletion takes effect immediately.
