Terms of service

Effective October 17, 2026

Operator. SuperNX is operated by Poetical Engine LLC, a New Mexico limited liability company, 1209 Mountain Road Pl NE, Ste N, Albuquerque, NM 87110, USA. “We”, “us” and “SuperNX” in this document mean Poetical Engine LLC.

These terms govern your use of SuperNX, the tolerance-chain analysis service at nxtolerance.com. By creating an account, uploading a part, or subscribing, you accept them. If you are evaluating on behalf of a company, the company is bound by them.

The service

SuperNX analyses Siemens NX part files (.prt): it extracts geometry and assembly interfaces, assigns fits from published tolerance standards, runs worst-case and statistical stack-up checks, and returns a report plus a toleranced model. Analysis runs consume credits; a demo mode needs no upload and no credits.

Accounts

Sign-in is via Google Firebase. Keep your credentials to yourself and your account information accurate.
One account per person or entity. Workspace plans may share an account's seat per the plan you buy.
You must be able to form a binding contract where you live.

Billing

Paid plans are sold by Creem, our merchant of record: Creem processes the payment, collects applicable taxes (VAT/GST/sales tax) and issues the receipt. Your card statement may show CREEM* plus the product name — that is this subscription.
Subscriptions renew automatically each billing period until cancelled. Cancel any time; access continues to the end of the paid period.
Each paid period grants a block of analysis credits as shown on the pricing page or your plan receipt. Failed runs — a crash, a timeout, an analysis that errored before delivering — refund their credits automatically; you are never charged for compute that produced nothing.
Something wrong with a charge? Email support@nxtolerance.com within 14 days and we will make it right. For anything payment-side (a duplicate charge, a card problem) Creem support can also help from the receipt email.

Your content and ours

Your parts stay yours. You keep all rights in files you upload and in the reports and models the service produces for you. We claim no ownership and only process them to provide the service — we do not use them to train models, share them, or sell them. Details and the retention schedule live on the security page.
Our service stays ours. The software, models, design and site content are ours. Do not copy the service, probe its internals beyond normal use, or resell access.

Acceptable use

Upload only files you own or are authorised to process.
No unlawful content, no attempts to break or overload the service, no scraping of other users' data.
We may suspend accounts that abuse the service; abuse-free cancellation never needs a reason.

Engineering responsibility

SuperNX is an analysis assistant, not a licensed engineer. Outputs are computational checks against published tolerance standards — useful, but not a substitute for professional engineering review. Verify results before they drive manufacturing, safety, or contractual decisions.

Disclaimers and liability

The service is provided as is, without warranties of uninterrupted availability or fitness for a particular purpose.
To the maximum extent the law allows, our total liability for any claim is capped at the fees you paid in the 12 months before the claim.
Nothing in these terms limits liability that cannot legally be limited.

Ending the relationship

Email privacy@nxtolerance.com any time to delete specific analyses or the whole account — deleting the account removes account data, stored outputs and our email history with you (Team plan inquiries included), per the privacy policy. We may suspend or close accounts that breach these terms.

Changes

If these terms change materially, the effective date above moves and the change is announced on this page before it applies to renewals. October 17, 2026: named the operator, Poetical Engine LLC, and the governing law is now that of New Mexico, USA. October 8, 2026: account deletion also removes our email history with you, and we corrected how analyses are deleted (by email to privacy@nxtolerance.com).

Law

These terms are governed by the laws of the State of New Mexico, United States, where the operator is established, without regard to conflict-of-law rules.
