Introduction
Infinite SAT: Math Prep (“the App”) is developed by Synergy Math SP. We are committed to protecting your privacy. This policy explains how we handle your data in accordance with modern mobile standards and platform requirements, including those of the Apple App Store and Google Play Store.
No User Accounts
The App does not require you to create an account or provide personal identity information (such as name, phone number, or email address). We use an anonymous, random “Device ID” to identify your progress and manage your access.
Data Storage and Synchronization
• Practice Data: Your math practice progress, mastery levels, question attempts, and settings are stored locally on your device.
• Warning: If you delete the App or clear its data, your local practice history will be permanently lost as it is not currently backed up to our servers.
• Premium Access: To ensure you can recover your purchase if you switch devices, we store your anonymous Purchase Token and Expiration Date on our secure server (Supabase). This allows the “Restore Purchases” feature to work accurately.
Data Collected Automatically (Analytics)
To improve our math content and app performance, we collect anonymous, aggregated session data, which is sent to our secure database (Supabase). This includes:
• Session Statistics: Total time practiced, number of questions solved, accuracy rate, and mastery level snapshots.
• Purchase Metadata: Non-personal transaction tokens and product IDs to manage entitlements.
• Technical Data: Device type (Android/iOS) and App version.
• General Location: Your City and Country, derived from your IP address.
Important clarification: IP addresses are used transiently to determine approximate location and are not stored.
Anonymity and Data Linking
All collected data is associated with a random UUID (Device ID). This data:
• is not linked to your identity
• cannot be used to identify you personally
• is processed only in anonymized or aggregated form
Tracking
We do not track users across apps, websites, or services owned by other companies.
We do not use data for advertising purposes or share data with data brokers.
In-App Purchases
If you purchase a Premium access package, the transaction is handled by the platform provider:
• On Android, purchases are processed by the Google Play Store.
• On iOS, purchases are processed by the Apple App Store using Apple’s in-app purchase system.
We do not see or store your credit card or billing information. We only receive and store an encrypted transaction token or receipt to verify your access duration.
Children’s Privacy
The App is intended for students preparing for the SAT. We do not knowingly collect personal information from children under 13. All data collection is anonymous and complies with applicable children’s privacy regulations (including COPPA and GDPR-K).
Third-Party Services
The app uses the following third-party providers to function:
• Supabase: For curriculum delivery, anonymous analytics, and premium entitlement storage.
• ipapi.co & IP-API: To determine general city/country location via IP address.
• Apple App Store & Apple Services (iOS only): For app distribution, security, and in-app purchase processing. Apple may collect certain usage and diagnostic data in accordance with its own privacy policies.
• Google Play Services (Android only): For app distribution, security, and billing.
