Overview

MathStreet ("the App") is an educational math game developed by Yoonki Hong. Your privacy is important to us. This policy explains what information the App collects and how it is used.

Information We Collect

Leaderboard Data

When you voluntarily submit your score to the global leaderboard, the App collects:

• Display name (the name you enter)
• Score and difficulty level

This information is stored on our servers (hosted by Supabase) and is publicly visible to other players on the leaderboard. Leaderboard entries are automatically removed after 28 days.

Local Game Data

The App stores your high scores and settings (sound, vibration preferences) locally on your device using standard device storage. This data never leaves your device.

Information We Do Not Collect

• Email addresses or account credentials
• Location data
• Device identifiers or advertising IDs
• Analytics or usage tracking data
• Photos, contacts, or any other personal data

Data Deletion

You can delete your global leaderboard entries at any time directly within the App. A delete option is available immediately after posting a score and next to your entries on the leaderboard.
