Quick Math Challenge — Privacy Policy

Last updated: 7 August 2026

Quick Math Challenge is a maths training game with timed drills, practice modes, scoring and optional Premium features. We designed it to collect as little data as possible. This policy explains what the app does and does not do with information.

In short: Quick Math Challenge has no accounts and no sign-in. Your progress, high scores and settings are stored on the device. We do not ask for, collect, or sell personal information. Ads in the free version are non-personalized. An optional one-time purchase removes ads and unlocks Premium modes.

Information we collect

We do not collect personal information. The app does not require an account, email address, phone number, name, or age, and it does not ask you for personal details.

Game progress (scores, streaks, preferences, sound/haptics settings and purchase entitlement state used to remove ads) is saved locally on the device using the operating system’s standard storage and Apple’s StoreKit. This information is not sent to a server we control.

Advertising

The free version may display advertisements provided by Google AdMob (banner, interstitial and rewarded formats). Ads are served in a non-personalized manner: they are not based on a user profile or tracking across apps, and the app does not use the device’s advertising identifier for cross-app tracking.

To serve and cap ads and to prevent fraud, Google may process limited, non-identifying technical signals (such as general device type and approximate, coarse region). Google’s handling of this data is described in the Google Privacy & Terms. A one-time Premium purchase removes advertisements.

Purchases

Quick Math Challenge offers an optional non-consumable in-app purchase (Premium / remove ads). All payments are handled directly by Apple through the App Store. We never see or store your payment details. You can restore purchases on a new device using Apple’s Restore Purchases flow.

Analytics

If anonymous usage analytics are enabled in a given build, they are used only to understand aggregate feature usage and crash/quality signals. They are not used to identify you personally or to build advertising profiles.

Children’s privacy

The app is suitable for general audiences practising maths. We do not knowingly collect personal information from children, we do not build profiles of children, and we do not use behavioural advertising or tracking directed at children. There are no social features, no chat, and no user-generated content shared with others.

Data sharing

We do not sell personal information, and we do not share personal information with third parties for their own marketing. The only third parties involved are the service providers that make the app work — Apple (app distribution and payments) and Google AdMob (non-personalized ads in the free version) — acting under their own privacy terms.

Data retention and deletion

Because progress and preferences are stored only on the device (and purchases with Apple), you can remove local app data at any time by deleting the app. Purchase restoration remains available through your Apple ID.

Changes to this policy

We may update this policy from time to time. When we do, we will change the “Last updated” date at the top of this page.
