Who we are. Second Brain is sold by RBBLG LIMITED, a company registered in England and Wales under number 17288170, at 128 City Road, London, EC1V 2NX, United Kingdom ("we", "us"). Contact: [email protected].
What you buy. A digital product: a folder of text files, a setup guide and related files, delivered as a download. Optional add-ons (Business Skills Pack, Pro Pack, Pro Pack Lite) are also digital downloads. Each is a one-time payment. Nothing renews.
What you need. The product runs inside your own account with one of two assistants: Claude (in the Claude desktop app, on a Claude Pro plan or higher) or ChatGPT (in Codex, inside the ChatGPT desktop app; a paid plan such as Plus is recommended). Claude and its plans are provided and billed by Anthropic, under Anthropic's own terms. ChatGPT, Codex and their plans are provided and billed by OpenAI, under OpenAI's own terms. We don't sell, control or guarantee either one, their prices, their features, their usage limits or their availability. If Anthropic or OpenAI changes its app or plans, parts of the product may need to be used differently. The optional routines in the Pro Pack are made for the Claude desktop app only.
Not affiliated. We are not affiliated with, endorsed by or sponsored by Anthropic or OpenAI. Claude is a trademark of Anthropic. ChatGPT and Codex are trademarks of OpenAI.
Your license. When you buy, you get a personal, non-transferable license to use the files in your own business, on your own computers. You may change the files as you like. You may not resell, share publicly or redistribute the files, in whole or in part.
Delivery. You get a download link on the thank-you page and by email right after payment.
Prices and payment. Prices are shown in US dollars, before any tax that applies where you live. The price you pay is the one on the payment page when you pay. Any promotion is shown with its end date and time. Payments are processed by Stripe. We never see or store your full card number.
Launch price. Until November 30, 11:59 PM ET, the kit is $29.99 (Black Friday launch price). A payment page opened at that price closes when it ends. From December 1, 2026, the kit is $59.
The kit is $59.
One-click offers. Right after your first purchase, on the pages that follow it, you may be offered an add-on. If you click "Yes", the card you just used is charged the amount shown on the button. Nothing is charged if you click "No thanks". Offers we send later by email open a normal secure payment page, where you confirm your card. They never charge your card in one click.
What the product does and doesn't do. The files tell the assistant (Claude or ChatGPT) to prepare drafts and wait for your approval before anything is sent, paid, posted or deleted. You stay responsible for what you send, sign or pay, and for checking drafts, numbers, dates and prices. The tools don't give legal, tax, accounting or medical advice. When in doubt, ask a professional.
No guaranteed results. We don't promise any specific amount of time or money saved. Results depend on your business and how you use the tools.
Refunds. See our refund policy.
Liability. To the extent the law allows, our total liability for any claim about the product is limited to the amount you paid for it. Nothing in these terms limits rights you have under the consumer law of your country.
Changes. We may update these terms. The version that applies is the one in force on the day you bought.
Law. These terms are governed by the laws of England and Wales, without removing the consumer protections of the country where you live.
