About this game

MathMaster is a school maths practice game for Classes 1–6. This policy describes the ad-free release published by NishArc Studios. Parents and guardians can help children use the game and manage its guest profile.

Information used by the game

The app creates a guest profile when it connects to our service. We process a random player ID, a generated or chosen nickname, an avatar selection, and authentication/recovery information. A random installation secret helps recover the same guest after a connection failure; the server stores a hash of that secret rather than the secret itself. Access tokens are used to authenticate requests. Please use a nickname instead of a real name.

We store learning progress such as the selected class, level and question position; completed levels; per-level correct answers and completion times; stars; in-game coins; quiz attempts and their timestamps. This game does not submit an all-time high score.

Session records include timestamps, foreground/playing/paused/background states, and active/play duration. We use these to operate the game, sync progress, understand activity and diagnose problems. Our hosting and database providers process technical connection information as needed to deliver and secure the service.

If you contact us, we receive the name, email and message you provide through our support/contact channel. Do not include a child's real name, access token or installation secret in a support message.

Purpose and service providers

We use this information to provide the guest profile, save and sync progress, show account information, track game activity, respond to support requests and protect the service. Our backend and its hosting/database providers process information to perform these functions. We do not sell player data or use it for targeted advertising.

Connections to the game service use HTTPS. Local progress and authentication details are stored on the device. No network service can promise absolute security.

Ads, purchases and device permissions

This release has no ads, advertising SDK or in-app purchases. It does not request access to precise location, contacts, camera or microphone, and does not use the Android advertising ID. Fonts and question content are included in the app. An internet connection is used for guest profiles, progress sync and session activity.

Children and parents

MathMaster is intended for school learners. We do not ask players for a real name, date of birth, email address or phone number in the game. Parents and guardians should supervise nickname choices and can use the account-deletion controls or contact us about a child's data. The app has no public chat, player messaging or public high-score leaderboard.
