Overview

MindMath Pro is a mental maths training app. This policy explains what data we collect, where it goes, and what we do with it. The short version: your full practice history stays on your iPhone, we never collect your name or precise location, and we use a small number of services to run the app and understand how it is used.

Information We Collect

Information stored on your device

The following is kept on your iPhone until you delete the app. Where a summary of it is shared with a service below, that section says so.

• 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 PostHog

PostHog is the analytics service we use, hosted in the EU. It receives:

• An anonymous identifier created by the app. This is not linked to your name or email.
• The screens you open and the features you use.
• Your onboarding answers, including your goal, target firm or test, and timeline, and how you heard about the app.
• Summaries of your practice, including score, accuracy, number correct and incorrect, difficulty, session length, and streak.
• Which interview questions you attempt and whether you got them right.
• Your reminder time, and whether you started, completed, cancelled, or restored a purchase.
