Build an App 101 is a guide: a walkable set of instructions for shipping a real app using Claude, written for someone who does not write code. Paying unlocks the whole guide past base camp, the Sherpa assistant, and everything added to it later. It is a one-off payment, not a subscription. There is nothing to cancel.
It is teaching material, not professional advice, and not a guarantee. Whether your app is accepted by any app store, works, earns money, or complies with the law where you live depends on what you build and on decisions those companies make. Nothing here is legal, tax, financial or accounting advice.
The guide describes third-party services — Apple, Google, hosting providers, payment processors, Claude itself. Those are not ours. Their rules, prices and screens change, and sometimes they change faster than a guide can. Always check the current thing in front of you.
If it is not what you expected, ask for your money back within 30 days and you will get it. No form, no reason required, no questions about how much you read. Email arun@arunkumar.io with the address you paid from.
The five foundation checkpoints are free precisely so you can tell whether this is written for you before paying anything.
If you are in the UK or EU, you also have a statutory right to cancel a digital purchase within 14 days. That right can be waived when you ask for immediate access, and the checkout will ask you about that. The 30-day promise above is separate and more generous, and you keep it either way.
The key unlocks the guide for you. Please do not post it publicly or share it around — it is one purchase, and a key that turns up in public gets switched off. If yours stops working and you did not expect that, email and it will be sorted out.
Keys are stored only as a one-way hash, so nobody — including us — can look yours up. Keep your receipt; if you lose the key, we can issue a new one against the payment.
The guide is designed to keep working offline once loaded. The Sherpa needs a connection and a working third-party service, so it can be unavailable from time to time. Everything else continues to work when it is.
Payment is handled by a third-party merchant of record, who is the seller for the transaction and handles tax where you live. Their name appears on your receipt and on your card statement. The guide itself is made by Arun Kumar.
These terms may change. Changes are not applied retroactively to a purchase already made.
