Effective date: July 5, 2026
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, CleanUpsell, PreorderLite, StockPing) and our web-based content tools. 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), CleanUpsell (post-purchase upsells), PreorderLite (pre-order management), and StockPing (stock alerts) — 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.
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.
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.
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 United States, without regard to conflict-of-law principles.
Use of the Services is also subject to our Disclaimer at /disclaimer, incorporated by reference.
