This Privacy Policy explains how Math Game (the Android / iOS app — Android package com.oojohn.countcard,
iOS bundle ID com.mrjc0509.countcard — the "App") collects, uses, and protects your information.
The App is developed and operated by MRJC ("we", "us").
By installing or using the App, you agree to the practices described here.
When you create an account or sign in, we collect the following:
| Data | Purpose | Required? |
|---|---|---|
| Email address | Account creation, sign-in, account emails (e.g. password reset) | Required for email sign-in |
| Nickname | Displayed on the leaderboard | Required |
| Avatar image | Personalization (optional upload) | Optional |
| Country / region | Leaderboard and statistics grouping | Optional |
| Device identifier | Distinguish devices, associate guest data | Auto-generated |
| Game data (scores, level progress, practice history) | Save progress, compute and show leaderboards | Generated during use |
| Account entitlement status | Provide corresponding account features | Automatic |
We do NOT collect: your birthday or age, precise location, contacts, SMS, or call logs.
If you play as a "guest" without signing in, game data is stored locally on your device and is not linked to any personal identity.
In the version published on Google Play, the App integrates Google Firebase Analytics and Crashlytics to understand overall usage and to diagnose crashes. These services may automatically collect:
This data is used to improve the App's quality and stability and is not sold. Test/development builds do not include these analytics features.
We do not sell or rent your personal data to third parties, and we do not show third-party ads in the App. We use Google Firebase only for usage analytics and crash diagnostics to improve the App (see Section 3).
The App relies on the following third-party services, which process some of the above data under their own privacy policies:
| Service | Purpose | Privacy Policy |
|---|---|---|
| Supabase | Authentication, database, and file storage (stores the account and game data above) | supabase.com/privacy |
| Google Firebase (Analytics, Crashlytics) | Usage analytics and crash diagnostics to improve the App (release builds only) | firebase.google.com/support/privacy |
| Google Sign-In | If you choose to sign in with Google | policies.google.com/privacy |
| Apple Sign-In | If you choose to sign in with Apple | apple.com/legal/privacy |
| Resend | Sending account-related emails | resend.com/legal/privacy-policy |
Your data is retained until you delete your account. You can delete your account and all associated data at any time:
The App is intended for users aged 13 and older. It is not directed at children under 13, and we do not knowingly collect personal information from children under 13. Children under 13 can still play in solo/guest mode, which requires no account and stores game data only on the device. If you are a parent or guardian and believe your child has provided personal information without consent, please contact us at the email below and we will delete it promptly.
Data is transmitted over encrypted connections (HTTPS/TLS) and stored in access-controlled Supabase services. However, no method of transmission or storage is 100% secure.
We may update this policy from time to time. For significant changes we will update the "Last updated" date at the top of this page. Please review this page periodically.
