Solely to provide the Service: generate and validate problems, run your code, give coaching, track your progress, enforce budgets/limits, and deliver and support purchases. We do not use your data for advertising and we do not sell it.
To power generation and coaching, the content of your problems, code, and chat messages is transmitted to Google's Gemini API and processed under Google's terms. We send only what is needed for the feature you invoked. Your API usage with us is metered but the API key is held server-side and never exposed to your browser.
Payments and billing are handled by Lemon Squeezy as merchant of record. Their handling of your payment information is governed by their privacy policy. We do not store full card details.
Session practice data persists so you can return to your workspace, and is retained while your session/pack is active and for a reasonable period afterward. You can request deletion of your session data by contacting us with your pack code or session details.
Data is kept on our server with access controls, and AI keys are server-side only. No method of storage or transmission is perfectly secure, but we take reasonable measures to protect your data.
Depending on your jurisdiction, you may have rights to access, correct, or delete your data. To exercise them, email [email protected].
We may update this policy; the "Last updated" date reflects the latest version.
