Terms of sale.

Who sells this

Russell Tech LLC (“we”) sells Grok Mastery. Contact [email protected] or +1 605-280-3098. Cards show as RUSSELL TECH LLC. We are the seller of record. Stripe processes the payment. Stripe is not the merchant of record for this product.

Not xAI

Grok Mastery is a Russell Tech LLC product. It is not an xAI or SpaceXAI product, and it is not affiliated with, sponsored by, or endorsed by xAI. Grok, grok.com, Grok Build, and related names are theirs. We used Grok as a tool. Russell Tech directed the work, owns the lessons, hosts the desk, sells the seat, and stands behind it.

What you buy

You buy access to the Grok Mastery training desk on learn.russelltech.us: the pathways, lessons, and exercises as they stand, plus the updates we publish when Grok changes. Monthly is $20 / month while the subscription is current. Lifetime is $197 once. The lessons are rewritten when Grok changes — new surfaces, new defaults, new ways it fails. Lifetime is not a PDF from launch week.

What you do not buy

A Grok account is separate and billed by xAI. SuperGrok or Build credits, if you need them, are not included here. xAI’s terms govern that account. You buy a method and a practice desk, not a result. Outcomes depend on your own work and on how Grok behaves, which changes. We do not guarantee a job, a grade, a credential a third party must honor, or that the model will look the same next month.

Tax

Listed prices are before tax. Stripe Tax adds sales tax, VAT, or GST only in places where Russell Tech is registered to collect it. Checkout collects a billing address so Stripe can calculate tax. A business tax ID is optional; if you give one, Stripe may apply reverse-charge or zero-rate rules where those rules apply. We remit collected tax to the jurisdictions where we are registered. Zero tax on a receipt means we are not registered to collect in that place — not that the sale is exempt for your own books.

The seat

One paid email is one seat. Do not share the login. We can close a seat that is shared, abused, or used to copy the desk for resale. Monthly access ends when the subscription ends. Lifetime access lasts as long as we operate the desk. Sales are final. See cancellation.

Intellectual property

The lessons, published prompts, exercises, and site design are Russell Tech’s. You may use the method in your own work. You may not copy the desk, resell the lessons, or share a login. Work you paste into an exercise stays yours. The paste reaches this server on Submit. We delete the body when you mark the lesson complete, and you can delete in-progress work from your account. Grok’s output is subject to xAI’s terms, not a license from us.

No warranty

The desk is provided as is. We disclaim implied warranties of merchantability and fitness for a particular purpose to the extent the law allows. We are not liable for how you apply what you learn, for xAI outages or model changes, or for lost profits or indirect damages. If we are liable anyway, that amount is capped at what you paid us for the desk in the twelve months before the claim.

Law

South Dakota law governs these terms, without regard to conflict-of-law rules. If a court finds one clause unenforceable, the rest still stands. These pages are the agreement for the desk. They are not legal, tax, or accounting advice for your business.
