Volatile Memory Execution — Zero Code Harvesting
Array values, custom graph nodes, binary search trees, and custom test vectors entered into the simulation engine remain in volatile device RAM. No user inputs, custom test cases, or interview practice sessions are logged, analyzed, or uploaded.
01 Step-by-Step Simulation Isolation
The application visually illustrates nearly 100+ algorithms—including sorting (QuickSort, MergeSort, HeapSort), searching, pathfinding (Dijkstra, BFS/DFS), dynamic programming, heaps, and tree structures. The step-by-step computation occurs completely client-side in real time without network dependency.
02 Google AdMob & In-App Purchase Unlocks
The free edition integrates Google AdMob to deliver standard banners and interstitials to support development. Ad requests adhere strictly to Google Play Developer Policy and user privacy consent preferences.
Users may purchase the premium ad-removal unlock via Google Play Billing. Payment verification occurs directly through Google Play's infrastructure without exposing sensitive financial credentials to RakMind.
03 Learning History & Data Retention
Your quiz scores, bookmarked algorithms, and custom display configurations are stored strictly within the app's private sandbox. We do not maintain any external account systems.
04 Security & Contact
