How does the difficulty system work throughout the day?

The app starts with gentle warm-up math problems on the first attempt. By the second attempt, it escalates to two-digit arithmetic. By the third and subsequent attempts, math becomes complex enough that users typically decide it's not worth the effort and put their phone down. The difficulty adapts based on how easily users solve each challenge and softens if they're tired or make mistakes.

Does Scroll Brake require registration or collect data?

No. Scroll Brake requires no registration, emails, or account creation. All rules and usage counters stay 100% locally stored in the browser or device. The Chrome extension uses zero data collection and no accounts are needed. The app respects complete privacy by design.

Is my personal data and app usage private?

100% private. Neither the iOS app nor the Chrome extension requires an account, email, or registration. Scroll Brake uses Apple's native Screen Time API (FamilyControls framework) and local browser storage. Your browsing history, screen time, and app usage never leave your device and are never sent to any server. There are zero ads, zero tracking, and zero telemetry.

What if I am bad at math or have an urgent situation?

Scroll Brake features automatic level detection. During onboarding, you take a quick diagnostic test to establish your baseline. From there, our adaptive algorithm dynamically adjusts math difficulty to your personal skill level based on your solving speed and accuracy. Essential apps can also be exempted entirely, and for emergencies you can configure bypass rules in your iOS settings or tap "Nevermind, I'll stop scrolling".

Is there a paid subscription or Pro version?

Scroll Brake includes generous core features out of the box with zero ads: up to 3 active app limits, all 7 adaptive math levels, and the complete Chrome extension for $0. For power users who need unlimited app rules, Strict Mode with daily unlock caps, and full weekly Screen Time analytics, iOS Pro is available for $3.99/month, $12.99/year, or a one-time $17.99 Lifetime unlock.
