Privacy & Terms
For MathFlow, the math practice app also listed as “SAT Math Prep: ACT & Calculus,” provided by Anul Agarwal. App identifier: com.momo.math.flow.
Privacy Policy
MathFlow stores practice records locally and uses RevenueCat for anonymous customer records, purchase validation and premium access. No account is required. We do not run advertising or send math answers to an AI service.
Learning data
Your learning level, exam goals, language, preferences, mastery, streaks, XP, achievements, mistake-journal answers and Math Connect progress are stored in local app storage. Questions and explanations are generated in the app. We do not upload learning records to our servers or RevenueCat. Your operating system may separately back up app data according to your device settings.
If you share a session result, the app opens the device share sheet with the topic and a summary such as correct and attempted answers, accuracy and duration. You choose the destination, which handles that copy under its own policy.
RevenueCat and payments
RevenueCat initializes when the app runs, including for free users. It creates a random anonymous app user identifier and processes basic service information such as app and SDK versions, device model, operating system, locale and store context. Network connections necessarily transmit information such as an IP address. This supports service operation and customer reporting, not a complete count of store downloads.
Apple or Google processes payments. RevenueCat processes available store receipts, purchase history, product identifiers, subscription status and entitlements to validate purchases, maintain access, prevent fraud and provide purchase analytics. We do not receive payment-card details. Anonymous identifiers still distinguish an app instance; “anonymous” does not mean no data is collected.
The app does not set a name, email address or custom account ID in RevenueCat, configure advertising attribution networks, enable cross-app advertising tracking or enable optional RevenueCat diagnostics. Service data is sent over encrypted connections. See RevenueCat’s privacy policy, Apple’s privacy policy and Google’s privacy policy.
Analytics and device features
The optional Firebase Analytics integration is controlled by the app’s analytics preference. This release has no Firebase project configuration, so that integration is inactive. The preference does not disable RevenueCat’s operational and purchase processing. Future changes will be reflected in the app and this policy.
Practice reminders are scheduled locally with notification permission. Change the reminder setting or revoke permission in device settings. Apple or Google handles any store review you choose to submit.
Support and this website
Emailing anulagarwal12@gmail.com sends us your address and the information you include, which we use to respond. Avoid unnecessary personal information or sensitive learning records. External links are governed by their destination policies. This website’s hosting provider processes ordinary web-request information to deliver and protect these pages; the page has no analytics scripts or advertising.
Retention, deletion and choices
Settings → Reset Progress clears learning progress on that device, not all preferences, purchases or RevenueCat records. Removing app data or uninstalling follows your operating system’s rules; backups and shared copies may remain and must be managed separately.
For access, correction or deletion requests concerning service or support records, email us and identify MathFlow. We may need information to locate the relevant anonymous app instance or transaction; matching may not be possible without it. Never send payment-card details or store passwords. Service and support data is retained for the purposes above, subject to applicable transaction-record, fraud-prevention and legal obligations. Deletion does not automatically cancel a subscription.
We use service providers for these functions, not to sell personal data or target advertising. Information may be processed outside your country. We may disclose information where required by law or necessary to protect security and legal rights. No transmission or storage system is completely secure.
Students and families
MathFlow offers middle-school material through advanced study. It does not ask for a birth date, school name, student account or contact details to practice. Parents and guardians should supervise children’s use and purchases. If you believe a child provided personal information through support or another app-related interaction, contact us so we can investigate and address it. Local learning records are not sent to our service providers.
Updates and contact
We will update this policy when practices change and provide any notice or consent required for material changes. Contact Anul Agarwal at anulagarwal12@gmail.com with privacy questions.
Terms of Use
Educational use
MathFlow provides generated math practice, hints, worked solutions, progress tracking, exam practice and Math Connect puzzles for personal educational use. Use it lawfully on compatible devices under these terms and your app store’s terms. Do not misuse the service, infringe rights or interfere with security. A parent or guardian should supervise use and authorize purchases where required.
Practice is not an official examination service or a guarantee of grades, admission or results. MathFlow is not affiliated with or endorsed by the organizations that own the SAT, ACT, AP, IB, Suneung or Gaokao names. Material may contain errors; verify important learning content with a teacher or reliable source and report mistakes to support.
Free and paid features
Free access includes eleven foundation topics, unlimited practice in all three modes, hints, solutions, concept cards, progress, mastery, streaks, XP, achievements, the mistake journal and Math Connect. Pro adds seven advanced topics, seven exam paths and skip-ahead. The purchase screen identifies available plans and current localized prices.
Weekly subscription
The weekly plan auto-renews. Your store account is charged the displayed total weekly price. It renews for another week unless canceled before renewal in the store’s subscription settings, subject to the store’s renewal-processing rules. No free trial is promised for this release. Uninstalling or deleting progress does not cancel a subscription. Cancellation normally stops future renewals; access continues for the paid period, subject to refunds and store decisions.
Lifetime purchase
Lifetime is a one-time, non-consumable Pro unlock without recurring subscription charges. It is tied to the purchasing store account and is not a promise of uninterrupted operation on every future device or operating system. It does not transfer automatically between Apple and Google accounts or stores. Mandatory consumer rights are unaffected.
Restore, refunds and availability
Use Restore Purchases with the same store account used to buy. Validation and restoration require internet access and availability of Apple, Google and RevenueCat. Refunds and billing disputes follow the relevant store’s processes and applicable law. Do not share store credentials with support. Losing Pro access does not delete local progress; free features remain available.
Core practice works offline. Downloads, purchases, restores and entitlement updates depend on external services. Keep the app and device updated and manage backups according to your operating system. We may improve features, correct errors or discontinue unsupported functionality, subject to law and purchase commitments. Nothing here excludes rights or remedies that cannot lawfully be excluded.
Platform terms and contact
Apple’s Standard Licensed Application End User License Agreement applies to the iOS app license. Google Play’s terms apply to Google Play distribution and payment. Mandatory local consumer protections continue to apply. Contact Anul Agarwal at anulagarwal12@gmail.com for help.
