Effective date: August 25, 2026
Changelog: August 25, 2026 — added binding arbitration and class-action waiver (Governing Law and Disputes), added refund terms for the x402 Setup service and the AI-Visibility Audit/Re-verify, updated governing law to California.
These Terms of Service ("Terms") govern the use of Stelar Digital LLC's applications and services ("the Services"), operated by Stelar Digital LLC ("we", "us"), including our Shopify applications (FlatInvoice, StockPing, Aivis, Stockyard) and our web-based content tools. Two earlier Shopify apps, CleanUpsell and PreorderLite, are discontinued and no longer distributed. By installing or using any of the Services you agree to these Terms.
The Services include our Shopify applications — FlatInvoice (PDF invoices and packing slips), StockPing (stock alerts and back-in-stock notifications), Aivis (AI-order attribution and AI-visibility scans), and Stockyard (supplier and purchase-order management) — as well as our web-based content tools, which include a tool used to publish Stelar Digital's own market-update videos to Stelar Digital's own social media accounts, including TikTok. CleanUpsell (post-purchase upsells) and PreorderLite (pre-order management) are discontinued and no longer distributed.
The following sections apply to the Services generally, including our Shopify applications.
Where a Service is offered as a paid subscription, billing is handled through Shopify Billing (for Shopify apps) and appears on your regular Shopify invoice. No payment details are collected by us directly.
You may cancel a Shopify app subscription at any time by uninstalling the app from your Shopify store. Billing stops automatically upon uninstall through Shopify Billing; no separate cancellation step is required.
Our digital products are delivered immediately and are non-refundable once delivered: x402 API calls settle on-chain per call; the $79 Conformance Report is non-refundable once the report has been generated and delivered; digital downloads (guides, templates) are non-refundable once accessed. One exception, on us: if a paid Conformance Report fails to deliver, or a delivered report contains an error that is ours, we re-run it or refund it — your choice. Contact stelardigital@stelardigital.com.
$149 x402 Setup service. This is a service, not an instant digital delivery: we target delivery within 48 hours of you sending everything we need to start. If we are unable to deliver — the paywall wiring, pricing, catalog listing, and a proven paid test call — you get a full refund. Once delivered and the proof-of-work test call has settled, the service is complete and the fee is non-refundable.
$29 AI-Visibility Audit and $29 Re-verify. Same pattern as the Conformance Report: each report is delivered within 24 hours and is non-refundable once delivered. If the report fails to deliver, or a delivered report contains an error that is ours, we re-run it or refund it — your choice.
You agree to use the Services only for lawful purposes and, for our Shopify apps, only in connection with a store you own or are authorized to operate. You may not attempt to interfere with, reverse engineer, or disrupt the operation of the Services.
Per-call pricing is stated in each endpoint's HTTP 402 challenge; paying the challenge is acceptance of these terms for that call. Calls are metered and non-refundable once a response is served. You may not use the API to violate law, probe or overload our infrastructure beyond published rate limits, resell responses as your own live service without attribution, or misrepresent Doctor scan results as our endorsement. Automated/agent callers are welcome and bound identically. Responses are provided as-is per the No Warranty section; data endpoints are informational only and are not trading advice.
The Services are provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Services will be uninterrupted or error-free, or that generated documents will meet every jurisdiction's invoicing requirements. You are responsible for verifying that documents produced by our Shopify apps satisfy your legal and tax obligations.
To the maximum extent permitted by law, Stelar Digital LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity, arising out of or related to your use of the Services. Our total aggregate liability for any claim arising from these Terms or the Services shall not exceed the amount you paid us in the three (3) months preceding the claim.
We may modify the Services or these Terms at any time. Continued use of the Services after changes take effect constitutes acceptance of the revised Terms.
These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules. For any matter not subject to the arbitration clause below, the exclusive venue is the state courts of Placer County, California, or the U.S. District Court for the Eastern District of California, and you consent to personal jurisdiction there.
Binding individual arbitration; no class actions. Any dispute between you and Stelar Digital LLC arising out of or relating to the Services must be resolved by binding, individual arbitration, not in court, and not as part of a class, collective, consolidated, or representative action. Arbitration will be administered by JAMS under its Streamlined Arbitration Rules and Procedures (the JAMS consumer/small-business track), seated in California, before a single arbitrator. Either party may instead bring a qualifying individual claim in small claims court in lieu of arbitration.
Fees. Who pays which arbitration fees is governed by the JAMS Streamlined Rules (and, where applicable, JAMS's consumer minimum-fee schedule) then in effect — we don't set our own fee-shifting rule here; JAMS's published schedule controls.
Delegation. The arbitrator, not any court, has exclusive authority to resolve any dispute about the interpretation, applicability, enforceability, or formation of this arbitration clause, including any claim that all or part of it is void or voidable — except for the class-action-waiver enforceability question and the public-injunctive-relief carve-out below, which a court decides.
Public injunctive relief. Nothing in this clause waives your right, if any, to seek public injunctive relief in court, in the narrow circumstance where California law (per McGill v. Citibank) does not allow that right to be arbitrated or waived. Any such public-injunctive-relief claim is carved out of arbitration and may proceed in court; everything else about your dispute still arbitrates.
If the class waiver can't be enforced. If a court finally determines that the class/collective/representative-action waiver in this clause is unenforceable as to a particular claim, then that claim (and only that claim) will proceed in court rather than in class arbitration — arbitration on a class, collective, or representative basis is never the fallback.
30-day opt-out. You can opt out of this arbitration clause entirely — for this and any future order — by emailing stelardigital@stelardigital.com with your name, the account or order in question, and a clear statement that you opt out, within 30 days of your first order or first use of the Services, or within 30 days after these Terms take effect, whichever is later. If you opt out, disputes proceed in the courts named above (individually, not as a class action) instead of arbitration; everything else in these Terms still applies.
Use of the Services is also subject to our Disclaimer at /disclaimer, incorporated by reference.
