Privacy Policy

Math Games · com.quickbrain.mathgames

Last updated: 27 July 2026

The short version: Every game runs offline and we — the developer — keep no personal data and no accounts. The app is free and shows ads through Google AdMob, which needs internet and uses an advertising identifier. You can remove ads with a one-time purchase.

📋 Data we collect

We — the developer — do not collect any personal information. Your game progress stays on your device (see below) and is never sent to our servers. The app:

Runs every game offline on your device
Has no user accounts, sign-up, or login
Uses no analytics of our own
Requests only the permissions it needs — including internet access, which is used to load ads

The app is free and supported by ads, served by a third party — see the next section.

📢 Ads (Google AdMob)

Math Games shows ads using Google AdMob. To serve ads, AdMob and its partners may collect and process an advertising identifier (Android Advertising ID) and device & usage information such as device type, OS version and general location, used to select and measure ads. This data is handled by Google under its own policies — see Google's Privacy Policy and How Google uses data. Ads need an internet connection; the games themselves run offline.

💳 Remove Ads (in-app purchase)

You can make a one-time purchase to remove ads. Payments are processed by Google Play Billing — we never see or store your payment details. Your purchase is tied to your Google account so it can be restored on your other devices.

💾 Data stored on the device

The app saves a small amount of game progress — best scores, earned XP, stars, and unlock/progress state — only on the device itself, using Android's SharedPreferences. There is no database and no external game service. This data never leaves the device, is not linked to any identity, and is deleted when the app is uninstalled.

👶 Children's privacy

We do not knowingly collect personal information from children. Note that the app shows ads through Google AdMob; where the app is directed to or used by children, ads are configured as non-personalized. If you prefer no ads at all, a one-time purchase removes them. This policy is intended to align with the Children's Online Privacy Protection Act (COPPA) and the GDPR.

🔄 Changes to this policy

If a future version of the app ever changes how data is handled, this policy will be updated before that version is released, and the "Last updated" date above will change.
