Privacy Policy

Control Studios built SAT WordRush to help students master high-frequency SAT vocabulary. This application is provided by Control Studios and is intended for use as is.

We believe in privacy by design. We do not want your personal data. We do not sell your data. We build tools to help you learn — not to track you.

No Accounts & No Tracking

• No Accounts: You do not need to create an account to use SAT WordRush.
• No Ads: The app is completely ad-free.
• No Third-Party Tracking: We do not use advertising SDKs or third-party trackers.
• No Personal Data Collection: Control Studios does not collect, store, or process personal information such as names, email addresses, device identifiers, or precise location data.

Data Storage

Local Storage: All learning data — including word mastery levels, spaced-repetition schedules, and drill history — is stored locally on your device.

iCloud Sync (Optional): If you choose to enable iCloud sync, your learning progress is synced across your devices using Apple's private CloudKit database. Control Studios cannot access this data. It is encrypted and accessible only to you through your Apple ID.

Optional Research Data

SAT WordRush may optionally collect anonymized learning session metrics for educational and behavioral research purposes. These metrics may include aggregate statistics such as session duration, number of words attempted, and learning mode usage.

• No word content, definitions, or answers are collected
• No names, email addresses, or user identifiers are collected
• No data can be used to identify an individual user

Participation in research data sharing is optional and can be disabled within the app.

This anonymized data is used solely to study learning patterns and improve educational tools.
