Frequently asked questions

What's included for free?

10 full topics — Big-O Notation, Linear Search, Binary Search, Bubble Sort, Two Pointers, Singly Linked List, Stack, Hash Table, Binary Search Tree, and Selection Sort — each with a full explanation and an interactive visualizer. No account or sign-up needed.

What does the one-time purchase unlock?

All 28 topics, forever — no subscription. It's a single non-consumable in-app purchase processed through Apple.

I bought the full roadmap on another device — how do I get it back?

Open Profile in the app and tap Restore purchases. Make sure you're signed into the same Apple ID you purchased with.

Does the app collect my data?

Your progress, streaks, and settings are stored only on your device. The only data that leaves your device is what's needed to process the one-time purchase through Apple/RevenueCat — nothing is tracked or sold. Daily reminders are local notifications; nothing is pushed from a server.

How do I turn off the daily reminder?

Go to Profile → Reminders and toggle off "Daily streak reminder."
