CodeMaster does not show third-party ads and does not use the Advertising ID.

Learning progress, points, badges, preferences, and lesson status are stored locally on the user’s device.

If the user chooses to use the AI Tutor feature, the app sends the user’s question, code draft, answer draft, selected lesson context, language, and a basic app-generated client identifier to a secure server and AI service providers to generate a tutor response, apply rate limits, and protect the service from abuse. Requests are encrypted in transit using HTTPS.

CodeMaster does not require account creation.
