CadetX is run by Defence Mania (Defence Mania Academy, Old Palam Road, Behind Mahila Park, Dwarka Mor, New Delhi 110078). This page explains what we collect, how AI is used on your results, where your data is kept and when it is deleted. For anything here, write to team.cadetx@gmail.com.
1. How we use AI
Two features use AI. Both run on models from Anthropic (Anthropic PBC, United States), called through its API.
| Feature | Model | What the model receives |
|---|---|---|
| Your personalised study schedule | Claude Sonnet 5.5 | Your diagnostic result as numbers: right answers out of questions for each section and topic, and the order of your study days. |
| Analysis of a full mock paper | Claude Haiku 5.5 | Your mock result as numbers: right answers and accuracy by subject and topic. |
| Tagging questions with syllabus topics (our team, before a paper goes live) | Claude Haiku 5.5 | Question text only. No student data. |

What the model receives
Question text only. No student data.
- Never sent to the AI: your name, email, phone number, city or payment details.
- Training: under Anthropic’s commercial terms, what we send through its API is not used to train its models. Anthropic processes it outside India.
- What we keep: the text the AI writes for you (the analysis, or the explanation of your schedule) is saved to your account. A separate usage log keeps only the model name, the size of the request, its cost and a timestamp, with no content.
- Accuracy: AI output is guidance, not a promise of a score or a selection, and can be wrong. Your marks and the order of your days come from fixed rules; the AI only explains them and suggests revision. If the AI is unavailable, you get the rule-based version instead.
- We use no other AI provider today. If that changes, this page changes first.
