Overview

Numbers Rush is a math puzzle game designed with privacy in mind. No account is required to play. The only personal information the app stores is the display name you choose during setup, saved locally on your device and used solely for personalisation. Your game progress, statistics, and preferences are also saved locally and never transmitted to any server.

Data We Collect

The only personal information the app stores is the display name you choose during setup. It is saved locally on your device, used solely to personalise your in-app experience (greetings, stats screens, etc.), and is never transmitted anywhere.

We do not receive your email address, location, device identifiers, or any other information that could identify you beyond the name you choose to enter.

All other data — game progress and preferences — is also saved locally on your device and never leaves your device.

Local Storage

The following information is stored locally on your device and is never transmitted anywhere:

• Your display name (entered during setup, used only for personalisation)
• Game statistics (points, streaks, puzzles solved)
• Completed daily puzzle records
• App preferences (theme, difficulty)

You can delete all locally stored data at any time by tapping Reset local progress in Settings, or by uninstalling the app.

Third-Party Services

The app is built with Expo, a development platform for React Native apps. On startup, Expo performs an over-the-air update check that transmits only the app's version number and project identifier — no personal data, device identifiers, or gameplay information is included. This does not constitute data collection under Apple's App Store guidelines.
