Overview
Math60 (“the game”) is published by Chand Studios LLC (“we”, “us”). You can play without creating a named account. The game uses an anonymous Firebase identity for online rankings. This policy explains what data the game uses and the choices you have.
The game is free to download and every question is available from the start.
Data stored on your device
Your best question reached, best score, longest streak, accuracy, coins, unlocked achievements, daily-challenge state and your sound and haptics preferences are stored locally on your device. A completed run's question number and score may also be sent to the leaderboard as described below.
Leaderboards
For online rankings, Firebase creates an anonymous user ID. The game sends that ID, your best question number and score, and a server timestamp to Google Cloud Firestore. Rankings are shown on all-time, daily, and weekly public boards without your name or email. Completed scores may be queued on your device while offline and sent when connectivity returns. Other players can see your rank and score under a shortened anonymous ID. You can play while the leaderboard service is unavailable.
Advertising and consent
The game shows optional rewarded ads and occasional interstitial ads through Google AdMob. To serve ads, Google may process an advertising identifier and standard ad-request data such as your approximate location (derived from your IP address), device type, and the ad slots shown.
Where required — for example in the EEA, the UK and Switzerland — the game presents a Google-certified consent request before requesting any ad, and respects your choice. If consent is required and not given, the game does not request ads at all.
Where your region requires it, you can revisit that choice at any time from Settings → Ad privacy options.

In-app purchases
The game offers an optional Remove Ads purchase, processed by the platform store — Google Play Billing on Android, Apple’s App Store billing on iOS. The store handles payment and holds your purchase history. We never receive or store your payment card details.
