Welcome to AlgoVolta ("we," "us," or "our"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website and services (collectively, the "Service"). Please read this policy carefully. By accessing or using the Service, you acknowledge that you have read, understood, and agree to be bound by this Privacy Policy.
When you create an account, we collect your email address, display name, and password (stored in hashed form). If you sign up or log in using a third-party OAuth provider (Google or GitHub), we receive your name, email address, and profile image from that provider. We do not receive or store your OAuth provider password.
If you subscribe to a paid plan, payment transactions are processed by Stripe. We do not directly collect or store your credit card number or bank account details. We store your Stripe customer ID, subscription status, plan type, and billing period dates. For details on how Stripe handles your data, see Stripe's Privacy Policy.
When you use the Service, we collect and store the code you write and submit, including in-progress drafts (autosaved), completed submissions, test results, execution status, runtime, and memory usage data. We also store your responses to pattern recognition quizzes, including your selected answers and whether they were correct.
When you request an AI-powered hint, we send context about the current problem and your code to the Anthropic Claude API to generate a response. We store the hint request prompt and the generated response in our database, associated with your account.
We track your learning progress, including which patterns and problems you have completed, your current position in each learning track, spaced repetition scheduling data, and your preferred programming language.

We use the following third-party services to operate the Service. Each has its own privacy policy governing how it handles your data:
Your code submissions are transmitted to Judge0, a code execution engine that runs your code in sandboxed containers for testing purposes. The code you submit and the resulting output are transmitted to Judge0 servers for execution.
When you request a hint, contextual information about the problem and your code is sent to the Anthropic Claude API. Anthropic processes this data to generate a hint response. See Anthropic's Privacy Policy for details.

If you choose to sign in via Google or GitHub, we receive basic profile information (name, email, profile image) from the respective provider. We do not receive your password from these providers. Each provider's own privacy policy governs how they collect and use your data during the authentication process.
We may use Google Analytics to collect aggregate usage data about how the Service is used. If enabled, Google Analytics uses cookies to track page views and user interactions. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
