Welcome to Maths Combat Arena (the "App"). Your privacy, and the privacy of your children, is of utmost importance to us. This Privacy Policy explains how we handle information in our App.
Designed with kids and families in mind, Maths Combat Arena collects NO Personal Information. We are fully committed to child safety and strictly comply with the Children's Online Privacy Protection Act (COPPA).
We do not collect, store, or share any personal information.
No email addresses
No passwords
No phone numbers
No real names or usernames
No physical addresses or GPS location data
To allow players to challenge each other online while keeping them completely safe:
Anonymous Login: The App uses anonymous authentication. This creates a secure, random user ID on our backend (Supabase) that is not linked to any real-world identity.
Fun Display Names: The App automatically generates playful, kid-safe names (e.g., SpeedyBrain_4201 or MathNinja_7829). Players never enter their own names, preventing the accidental sharing of personal information.
The App tracks fun educational stats to help players see their progress:
Number of games played and won
Best correct answer streak
Total correct and attempted answers
Favorite math operation (addition, subtraction, multiplication, division)
All of these statistics are stored locally on your device's private storage. They are never uploaded to a server, never shared with third parties, and cannot be accessed by anyone else.
For multiplayer battles, the App uses ephemeral realtime connection channels (Supabase Realtime) to synchronize game state:
When you create or join a room, a temporary communication channel is opened using a 6-digit room code (e.g., B22DHM).
We broadcast ephemeral game events (such as "player is ready," "answer submitted," and "game over") directly between the two connected devices.
No Database Storage: Multiplayer game sessions are database-less. Your answers, scores, and room details are processed in real-time and are never saved to a permanent database or server log. Once the game ends or you leave the room, the data disappears.
The App uses Supabase (a secure backend service provider) solely to facilitate anonymous authentication and secure, real-time multiplayer synchronization. Supabase does not use this data for tracking or advertising, and complies with industry-standard security practices.
No Ads: The App is completely ad-free.
No Tracking: We do not use any third-party tracking tools, analytics SDKs, or advertising identifiers.
Because our App is designed for children, we take special precautions to protect their safety online:
We do not collect any personal information from children under the age of 13.
We do not include any social media integrations, chat boxes, or open text input fields in the multiplayer screens where children could type personal details.
Authentication and multiplayer display names are fully automated and pre-configured to be anonymous.
