By accessing or using DataEngPrep.tech (the "Service"), an independent service operated by Aditya Kumar ("we", "us", or "our"), you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use the Service.
To access certain features of the Service, you must create an account. You agree to provide accurate, current, and complete information during registration and to update such information as needed. You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account.
All interview questions, expert answers, code examples, and study guides are free to read. Personalized AI features, including higher answer-analysis limits, mock interviews, resume optimization, and SQL coaching, require a Pro subscription.
We offer Pro with two recurring billing options:
Payments are processed securely through Razorpay (India, INR) and Stripe (international, USD). You authorize us to charge your chosen payment method. For subscriptions, you will be billed automatically until you cancel. You may cancel your subscription at any time from your account billing page. Cancellation will take effect at the end of your current billing period. Current pricing is always shown on the pricing page.
We offer a conditional 7-day money-back guarantee on the Pro subscription. To be eligible for a refund, all of the following conditions must be met:
The Interview Answer Vault purchased through the Store is a non-refundable digital download, except where applicable law requires otherwise.
Refunds, when approved, are processed back to the original payment method within 5–10 business days. We reserve the right to deny refund requests that we determine, in good faith, to be abusive (for example: bulk content scraping followed by a refund claim, multiple accounts created to claim multiple refunds, or refund requests outside the 7-day window).
For monthly and yearly subscriptions, you may also cancel at any time from your account billing page to stop future charges. Cancellation takes effect at the end of your current billing period — you retain access until then, but cancellation alone does not trigger a refund. If you want a refund in addition to cancellation and you are within the 7-day window, you must email us as described above.
The AI Interview Coach feature provides AI-generated responses and feedback. This content is generated by artificial intelligence and is intended for educational purposes only. We do not guarantee the accuracy, completeness, or suitability of AI-generated content. The AI Coach is a study tool, not a substitute for professional career advice or real interview practice.
All content, materials, and features of the Service, including but not limited to questions, answers, code samples, and design elements, are owned by DataEngPrep.tech or our licensors. You may not copy, distribute, modify, or create derivative works from any part of the Service without our prior written consent. Your use of the Service grants you a limited, non-exclusive, non-transferable license to access the content for personal, non-commercial use only.
To the maximum extent permitted by law, DataEngPrep.tech and its affiliates, officers, directors, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Service. Our total liability shall not exceed the amount you paid us in the twelve months preceding the claim. The Service is provided "as is" without warranties of any kind.
We may suspend or terminate your account and access to the Service at any time for violation of these terms or for any other reason at our discretion. You may terminate your account at any time by contacting us. Upon termination, your right to use the Service ceases immediately. Provisions that by their nature should survive termination shall survive.
These Terms shall be governed by and construed in accordance with applicable laws. Any disputes arising from these Terms or your use of the Service shall be resolved in the courts of competent jurisdiction.
We may modify these Terms from time to time. We will notify you of material changes by posting the updated Terms on this page and updating the "Last updated" date. Your continued use of the Service after such changes constitutes acceptance of the revised Terms.
