Who we are
Blueprint (https://learn.yashbhati.in) is an online course on system design and data structures, run by Yash Bhati, an individual based in India. In these terms, "we" means Yash Bhati and "you" means the person using Blueprint.
What you're buying
Some of Blueprint is free. A one-time payment of ₹299 (Indian rupees) buys lifetime access: every lesson, case study and outage write-up on Blueprint, including ones added later. "Lifetime" means for as long as Blueprint is offered online. If we ever shut it down, we'll give at least 30 days' notice by email.
Your access
Access is tied to the email address you enter when you pay. You can sign in on any of your own devices with an emailed sign-in link. There is no password. Keep access to that email account, because it's how you sign in.
Personal use only
Your purchase is a personal, non-transferable licence to use Blueprint for your own learning. Please don't share your sign-in, resell or redistribute the content, or copy it in bulk. We may suspend access that is clearly being shared or abused, after contacting you first where we can.
Payments
Payments are processed by Razorpay. We never see or store your card, UPI or bank details. Prices are shown in Indian rupees at checkout. It's a single payment, not a subscription, so you'll never be charged again automatically.
Refunds
See our refund and cancellation policy.
Content accuracy
Architectures in Blueprint are simplified teaching models based on public engineering blogs, talks and postmortems. They aren't internal documentation of any company, and the material is educational, not professional advice. We work hard to keep it accurate but can't promise it is free of errors.
Availability
We aim to keep Blueprint available at all times, but it may occasionally be unavailable for maintenance or reasons outside our control.
Liability
To the extent the law allows, our total liability to you for anything related to Blueprint is limited to the amount you paid us.
Changes to these terms
We may update these terms. The date at the top shows the latest version. Changes will never take away lifetime access you've already paid for.
Law
These terms are governed by the laws of India. Questions? Write to hello@yashbhati.in.
