Overview
MindMath Pro is a mental math training app. This policy explains what data we collect, where it lives, and what we do with it. The short version: most data stays on your iPhone, we never collect your name or location, and we only share anonymous subscription data with our subscription provider so we know which features lead to upgrades.
Information We Collect
Information stored on your device only
We do not send the following to our servers because we don't have any. It lives on your iPhone until you delete the app.
- Practice statistics, including total problems solved, correct and incorrect counts, accuracy rates, and per-operation accuracy.
- Daily streak count, last session date, and any banked streak freezes.
- Missed problems within a session, used for the in-app review screen.
- App settings, including chosen difficulty, timer settings, selected operations, daily reminder time, and whether the tricks panel is shown.
- Onboarding answers, including your chosen goal (quant, consulting, GMAT, general fluency, or brain training), target firm or test, timeline, and skill self-rating.
- Cached subscription status, so the app continues to function briefly when offline.
Information shared with RevenueCat
RevenueCat is the third-party service we use to manage subscriptions. They store the following:
- An anonymous user identifier they generate. This is not linked to your name or email.
- Subscription purchase events and your current entitlement status.
- The paywall trigger that led to a purchase decision, for example "daily limit reached" or "tricks library". This helps us understand which moments lead to subscriptions.
- Onboarding-derived attributes such as your chosen goal, target, and timeline. This lets us see, in aggregate, which audience segments convert.
Information processed by Apple
When you purchase a subscription or one-off product, Apple's payment system handles the transaction. We never see your card details. Apple's privacy policy applies to that part of the flow.
