Terms of Service

Updated 2026-08-28

Latest version posted: August 28, 2026

This website, including all content made available through the website (the "Site"), is owned and operated by Foggy Goggle Inc, doing business as NitroMule, and its affiliates (collectively, "NitroMule", "Provider", "we", "us", or "our"). The services and products (the "Services"), which may be made available to you directly by NitroMule or through a merchant-branded portal or third-party platform (a "Platform"), are subject to the notices, terms, and conditions in these Terms of Service (the "Terms"). "You", "user", and "account holder" refer to you as a user of the Site and/or Software (as defined below) and/or a subscriber to the Services.

The Services include www.nitromule.com , related websites, desktop applications and other clients, APIs, webhooks, quote embeds, and merchant-branded portals powered by NitroMule (together with any software we provide to access them, the "Software").

All references in these Terms to dollars or to "{{BODY}}quot; are expressed in U.S. currency unless otherwise specifically indicated. Unless otherwise agreed in writing with NitroMule, these Terms govern your access to and use of the Services. Your agreement with NitroMule always includes, at a minimum, these Terms and our Privacy Policy , which is hereby incorporated by reference. Practical how-to guidance (for example, voiding labels) may also appear in our FAQs ; if there is a conflict, these Terms control. By using the Services, you acknowledge and agree that NitroMule's collection, use, and disclosure of personal information is governed by our Privacy Policy.

For clarity, personal information collected by NitroMule may be disclosed to the United States Postal Service ("USPS"), UPS, FedEx, and other carriers in connection with the Services and pursuant to the applicable carrier's privacy policies and practices. In addition, if you access the Services through a Platform or connected store or marketplace, personal information may be disclosed to that Platform or connection as needed to provide the features you enable. Optional declared-value or premium coverage, where offered, is subject to these Terms and any coverage-partner terms shown at purchase.

You must be the older of: (i) eighteen (18) years, or (ii) at least the age of majority in the jurisdiction where you reside and from which you use the Services, to open an account.

1. Eligibility; Accounts; Security

Information you provide must be accurate and kept current. You are responsible for safeguarding your credentials—including passwords, passkeys, multi-factor authentication, API keys, store and carrier credentials, and webhook secrets—and for all activity under your account. Shared-login use of a single merchant account is at your own risk; we are not obligated to provide team seats or role-based access unless we expressly offer that feature.

You are responsible for losses arising from unauthorized use of your account. Notify us promptly at admin@nitromule.com if you suspect unauthorized access.

2. Changes to the Terms

NitroMule may, from time to time, modify, amend, or supplement these Terms, and post those changes on this Terms of Service page. Modifications, amendments, or supplements shall automatically be effective seven (7) days after NitroMule has posted them (or such later date as we indicate). If you do not agree to be bound by (or cannot comply with) these Terms as modified, your sole remedy is to cease using the Services by canceling your account. Your continued use of the Services after changes become effective constitutes your agreement to the Terms as modified, except where applicable law requires a different process. It is your responsibility to review these pages periodically.

3. Service Description; Plans and Pricing

Service Description.

Depending on your plan and configuration, the Services may include rate shopping; purchasing and printing labels and packing slips; pickups and tracking; order and tag management; product and package libraries; address books; shipping analytics; billing and saved payment methods; printing and carrier preferences; store and marketplace connections; branded portals; order notification emails; optional coverage or declared value; and developer tools such as API keys, webhooks, and quote embeds. Account settings let you manage these preferences. Some settings are available only on the main NitroMule site and not inside customer-facing portals. Feature availability may change over time.

Products and packages. Products represent what you sell (SKU, title, images, store identifiers, optional inventory). Packages represent how you ship (dimensions, weight, units). Assigned or default packages may pre-fill dimensions for rating; you must still verify accuracy before purchase. Inaccurate presets do not waive carrier audits or adjustment charges.

Service Pricing.

Prices are in U.S. dollars unless otherwise indicated and may change from time to time. Applicable taxes may vary. Payment methods accepted are shown at checkout and may change. Whether or not you pay a recurring platform fee, you are responsible for all variable and transactional costs of using the Services, including without limitation Carrier Charges (defined below), package insurance or optional coverage fees, fees for additional users or add-on features, costs of third-party service providers, transaction fees charged by NitroMule, and charges for other selected Services. We may limit sales by person, region, or jurisdiction on a case-by-case basis, and may modify or discontinue any Resource or feature without notice and without liability for such changes.

Beta Services.

You may be invited to participate in a beta or early-access program or beta Service offered by NitroMule (collectively, "Beta Services"). By using Beta Services, we grant you a non-exclusive, revocable, non-transferable, limited license to use them on an "as is" and "as available" basis. Beta Services may contain bugs, defects, or errors. You assume all risks and costs associated with your use of Beta Services. To the fullest extent permitted by law, NitroMule shall not be liable for damages relating to your use of Beta Services, and we are not obligated to provide maintenance or support for them. Feedback you provide regarding Beta Services is owned by NitroMule (see Section 12). We may modify or terminate Beta Services, or your access to them, at any time without liability.

4. Method of Payment; Carrier Charges; Post-Shipment Adjustments

Method of Payment.

At checkout, you authorize us and our payment processors (such as Stripe) to charge the payment method you provide for the quoted amount, taxes, and fees shown. Where checkout requires it, you also authorize charges for additional fees related to incorrect or incomplete package or shipment information and other post-shipment adjustments described in this section. That authorization applies to the order and, where recorded on your account, to eligible future adjustments. Acceptable payment methods are subject to change. Incorrect billing information may delay Service. Payment information is handled in accordance with our Privacy Policy.

Carrier Charges.

"Carrier Charges" means fees related to postage, label fees, fees for carrier services, dimensional weight adjustments or other adjustments, and other charges, penalties, or fees, as well as any applicable taxes or surcharges, charged by a carrier (or passed through by NitroMule) in connection with the purchase of shipping labels and other services from such carrier. You are responsible for all Carrier Charges attributable to your shipments.

Post-Shipment Adjustments.

We may assess, invoice, and collect additional charges relating to any shipment or service—including amounts identified after the original transaction, delivery, or completion of services. Examples include carrier adjustments or surcharges; corrections to weight, dimensions, or dimensional weight; address correction fees; residential or remote-area surcharges; oversize or overweight charges; fuel or other carrier surcharges; customs duties and fees; taxes; storage fees; re-delivery or delivery-attempt charges; return-to-sender charges; handling fees; insurance- or coverage-related charges; disclosed portal administrative fees; and other amounts properly attributable to the shipment. In our product these amounts are labeled carrier adjustments. That means a carrier (or related) billing adjustment passed through to you—not a card-network dispute and not a refund.

You agree we may charge or invoice such amounts for up to one hundred eighty (180) days after the original shipment date, even if the shipment was already delivered or the original payment completed. An expired receipt or invoice does not waive that right. Where permitted by law and where you have given required consent, you authorize off-session charges to any payment method on your order or account during that period. We are not responsible for delays in receiving carrier invoices; late notice from a carrier does not prevent collection within the 180-day window. You must keep at least one valid payment method on file while open orders or adjustment eligibility remain, unless we agree otherwise in writing.

We will use reasonable efforts to notify you of adjustments (including by email where configured). Review history in Billing settings. If you believe an adjustment is wrong, contact us promptly with supporting evidence. Do not file a payment-card dispute to avoid an authorized carrier adjustment unless you have a separate bona fide dispute about an unauthorized or clearly erroneous card charge. Abusive card chargebacks may result in suspension, recovery of amounts owed (including collection costs), and termination.

We may retain payment processor references for up to 180 days after a shipment or transaction, or longer for open claims, adjustments, accounting, or legal obligations, as described in the Privacy Policy.

5. Store and Marketplace Connections

You may connect third-party stores or marketplaces (for example, Shopify, WooCommerce, eBay, or Amazon) or import orders from CSV where we offer those features. By connecting an integration or uploading import files, you represent that you have authority to grant access; authorize us to process order, customer, product, inventory, location, and fulfillment data as needed for the features you enable; remain responsible for accuracy and for marketplace privacy and data-use rules; and agree to keep credentials secure and disconnect stores you no longer control.

We are not responsible for marketplace or store-host outages, policy changes, incorrect catalog or order data, or disputes between you and your buyers. Store sync creates or updates Products in NitroMule; packaging dimensions come from packages you configure (or values on the order). Inventory display or two-way inventory features, where offered, act on your instructions and may change stock in your connected store—you must verify those updates. CSV imports may contain personal information; you warrant you have a lawful basis to upload that data.

6. Carriers and Merchant Carrier Accounts

NitroMule is a shipping software and label platform. Except where we expressly say otherwise for a specific product, we are not the underlying parcel carrier, common carrier, or freight forwarder. Transportation is performed by third-party carriers such as UPS, USPS, and FedEx (and any additional carriers we enable). Carrier service guides, tariffs, and privacy practices govern carriage. International air or road carriage may also be subject to conventions such as the Warsaw or Montreal Conventions (or similar), which can limit carrier liability.

When you ship through NitroMule, you also accept the terms of the applicable carriers, including their tariffs, service guides, and any electronic user agreements they require.

Rates and labels may be offered through NitroMule-negotiated carrier accounts and/or, where enabled, through carrier accounts you connect. If you connect your own account, you authorize us to use those credentials to rate, purchase labels, schedule pickups, and perform related actions on your behalf. You remain bound by that carrier's terms (including any EULA you accept in our flow, such as FedEx onboarding). When you buy labels on your own carrier account, the carrier may bill you directly for postage and adjustments; when you buy labels on NitroMule-negotiated accounts, we typically invoice or charge you (including post-shipment adjustments) as described in Section 4. We may refuse or disconnect merchant carrier connections that present risk.

You are solely responsible for lawful contents, accurate descriptions, customs documentation, and compliance with carrier prohibitions and applicable export-control, sanctions, and import laws. Carriers, customs authorities, and security agencies may open and inspect shipments. Misdeclaration, hazmat violations, prohibited items, or export/import violations may result in fees, seizure, claim denial, suspension, and indemnity obligations under these Terms.

7. Branded Portals

If you operate a merchant-branded portal, subdomain, or custom domain through NitroMule, these Terms still govern platform use. You may post separate portal terms for your customers; those apply between you and them in addition to these Terms where they do not conflict with mandatory law or our role as platform operator.

As a portal operator, you are responsible for your branding, pages, FAQs, forms, coupons, markups, and policy content; for consents from your visitors; for custom SMTP or sender settings and anti-spam compliance; and for customer service in your portal relationship except where we expressly handle a platform billing or carrier issue. Portal checkout still runs on NitroMule infrastructure. You may not use portals to evade payment, adjustment, or prohibited-item rules. Portal visitors' merchandise relationship may be with the merchant; merchant-edited portal policy pages do not reduce obligations under these Terms for platform services purchased through us.

8. API and Developer Tools

NitroMule may make an API (Application Programming Interface), webhooks, and quote embeds available based on your account configuration, in our sole discretion. Any use of the API, including use through a third-party product that accesses NitroMule, is subject to these Terms plus the following.

Permitted Access.

You will only access (or attempt to access) the APIs by the means described in our documentation. If we assign you developer credentials (for example, API keys, including live and test keys), you must use them with the applicable APIs. You will not misrepresent or mask either your identity or your application's identity when using the APIs or developer accounts.

API Limitations.

We may set and enforce limits on your use of the APIs (for example, limiting the number of requests). You agree not to circumvent such limitations. We may withdraw your access to the APIs in our sole discretion. Abuse of rate limits, scraping, or using test keys for unauthorized live shipping may result in key revocation or account suspension.

Third-Party APIs; Your Obligations.

Our APIs may access third-party APIs to complete a request. Third-party APIs may require separate agreements, and we make no representation of performance for third-party APIs. Where offered, outbound webhooks and quote embeds operate under your instructions. You must secure credentials, validate webhooks on your systems, and comply with privacy laws for data you cause us to send or collect.

9. Desktop and Other Clients; Software License

Our desktop application and other clients use the same account and data plane as the website. Session or exchange tokens may be stored locally. Use of any NitroMule client is subject to these Terms and our Privacy Policy.

Subject to your compliance with these Terms, NitroMule grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Software solely to use the Services for your internal business purposes. You may not copy, modify, distribute, sell, lease, reverse engineer (except to the extent permitted by law), or create derivative works of the Software, or remove proprietary notices, except as expressly permitted in writing.

10. Shipping; Packing; Carrier Adjustments; Claims

Rates and Labels.

Rate quotes are estimates based on information you provide and carrier responses at quoting time. They are not a guarantee of final billed cost if audits or accessorials apply. You must enter accurate dimensions and weight (round measurements and weight up). Pre-filled values from products, packages, or store imports do not waive your duty to verify accuracy. If a carrier later re-measures or re-weighs a shipment, or assesses address-correction or other accessorial charges, those amounts are passed through to you as Carrier Charges under Section 4.

Packing.

You are responsible for packing that meets reasonable commercial standards and carrier requirements. Shipments may experience vibration, orientation changes, and handling comparable to drops from roughly waist height. Failure to pack adequately may result in claim denial and may contribute to carrier adjustments.

Carrier Adjustments.

A carrier adjustment is an extra charge the carrier applies after a shipment is in transit or delivered, passed through to you (not a card dispute and not a refund). Collection for eligible adjustments is described in Section 4. See our FAQs for practical tips on avoiding adjustments.

Claims.

For loss or damage in transit, contact NitroMule to open a claim unless we instruct otherwise. Claims must generally be filed within seven (7) days of delivery, with supporting documents within thirty (30) business days (and certain mis-delivery claims within fourteen (14) days of pickup). Documentation typically includes photos of damage and packing and proof of value. Optional coverage, where purchased, is subject to Section 11.

11. Optional Coverage and Declared Value

Where offered, you may select declared value or purchase optional premium coverage for shipment contents, subject to these Terms, carrier rules, and any third-party coverage provider terms (for example, UPS Capital when enabled). Unless coverage documents expressly state that a licensed insurer is issuing a policy to you, optional coverage is not traditional insurance. Coverage generally applies only while the package is in the carrier's possession, does not cover poor packing, and is limited to the lesser of selected value and market value (subject to published maxima at checkout). Approved coverage payments must typically be claimed within ninety (90) days.

12. Unused Labels; Refunds

You may request a refund for a successfully created but unused and unscanned shipping label by contacting admin@nitromule.com within thirty (30) days of purchase (or such longer carrier window as we can support). Refunds are subject to carrier rules and our review; used or scanned labels are not refundable. A void request does not guarantee a refund until the carrier confirms the void. USPS labels must typically be used within thirty (30) days of purchase. Do not use a label after requesting a refund. When you ship on your own connected carrier account, postage may be billed by the carrier (including pay-on-use); postage refunds may need to be requested from that carrier, while optional coverage or platform fees for an unused label may still be refundable through us. Carrier adjustments are not refunds. See our FAQs for how-to steps.

13. Acceptable Use; Prohibited Activities; Ineligible Items

You may use the Services only for their intended purposes and as permitted by these Terms and applicable law. You agree not to:

• Interfere with or disrupt our systems or third-party services we rely on;

• Copy, sell, or resell our Resources without authorization;

• Access the Services through unauthorized automated means (such as scraping or credential stuffing), except via documented APIs used in compliance with their terms;

• Misuse developer tools, API keys, or webhooks; or

• Use or attempt to use the Services for prohibited, hazardous, illegal, mis-declared, or carrier-restricted items, or shipments that violate export, import, sanctions, or other applicable law.

If we offer communication features (contact forms, claims, FAQs, comments, reviews, or chat), you will not submit unlawful, abusive, defamatory, fraudulent, infringing, spam, or impersonating content. We may remove content that violates these rules and may suspend or terminate access—including canceling orders where permitted—for violations, harassment, non-payment (including unpaid carrier adjustments), abusive payment-card chargebacks, or other prohibited activity.

Non-compliance with prohibited-item or packing rules may result in additional fees, fines, surcharges, claim denial, account suspension, or other actions at our discretion. We are not responsible for delays, losses, or damages related to prohibited or non-compliant shipments.

14. Intellectual Property; Feedback

Content on NitroMule interfaces (including text, graphics, logos, and software) is owned by or licensed to us and protected by intellectual property laws. Unauthorized use is prohibited. You retain ownership of your store content, logos, and customer data, and grant us a limited license to host and process that material as needed to provide the Services.

If you provide feedback, suggestions, or materials to NitroMule (including regarding Beta Services), you grant NitroMule a perpetual, irrevocable, royalty-free, worldwide license to use, reproduce, modify, and incorporate such feedback into our products and Services without obligation to you, to the extent permitted by law. If we publish such feedback, we will either do so in a way that does not identify you or seek your consent if we wish to identify you.

15. Privacy

Our Privacy Policy explains how we collect, use, and share personal information, including information from store connections, portals, carriers, and payment processors. It is incorporated into these Terms by reference.

16. Disclaimer

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL MEET YOUR REQUIREMENTS; THAT ACCESS WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE; THAT RATES, TRANSIT ESTIMATES, ADDRESS VALIDATION, STORE SYNC, OR ANALYTICS WILL BE ACCURATE; OR THAT CARRIERS, STORES, MARKETPLACES, OR PROCESSORS WILL PERFORM WITHOUT ERROR OR DELAY. USE OF DOWNLOADED OR PRINTED CONTENT IS AT YOUR SOLE RISK.

17. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, ANY CLAIM AGAINST US IS LIMITED TO THE AMOUNT YOU PAID US FOR THE SPECIFIC SERVICES GIVING RISE TO THE CLAIM DURING THE TWELVE (12) MONTHS BEFORE THE CLAIM AROSE (OR ANY GREATER AMOUNT REQUIRED BY LAW), EXCLUDING ANY AMOUNT EXPRESSLY LABELED AS A SERVICE DISRUPTION PAYMENT, IF APPLICABLE. WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, DATA, GOODWILL, INVENTORY DISCREPANCIES, MARKETPLACE STANDING, OR BUSINESS INTERRUPTION. WITHOUT LIMITING THE FOREGOING, WE ARE NOT LIABLE FOR CARRIER LOSS, DAMAGE, OR DELAY BEYOND OPTIONAL COVERAGE WE EXPRESSLY ADMINISTER UNDER THESE TERMS; FOR ACTS OR OMISSIONS OF INTEGRATIONS YOU ENABLE; OR FOR CARRIER AUDIT FEES. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS; THERE, OUR LIABILITY IS LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.

18. Indemnification

You agree to indemnify and hold harmless NitroMule, Foggy Goggle Inc, and their respective parents, affiliates, directors, officers, employees, and agents from losses, costs, damages, and reasonable attorneys' fees arising out of or related to: (a) your violation of these Terms or our policies; (b) misuse of the Services; (c) shipment contents, packing, declarations, or customs filings; (d) portal content and your relationship with portal customers; (e) store or marketplace connections you authorize; (f) API, webhook, or embed configurations you control; (g) Carrier Charges, carrier adjustment amounts, and related payment disputes; and (h) third-party claims arising from the foregoing.

19. Suspension and Termination

We may suspend or terminate access at our discretion, including for violations of these Terms, non-payment, or abusive payment disputes. Illegal or abusive activity may result in termination and referral to law enforcement. Upon termination, you remain responsible for outstanding orders, carrier adjustments, and amounts owed. Provisions that by their nature should survive—including payment, indemnity, limitation of liability, and governing law—survive termination.

20. Links to Third-Party Sites

The Site or Services may contain links to third-party websites or services that are not owned or controlled by NitroMule. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services. You access them at your own risk.

21. Governing Law; Venue

These Services are operated from Colorado, USA. The laws of the State of Colorado, without regard to conflict-of-law principles, govern these Terms and your use of the Services, except where mandatory consumer protection laws of your jurisdiction apply. Subject to applicable law, exclusive jurisdiction and venue for disputes lie in the state and federal courts located in Denver, Colorado. You waive objection to personal jurisdiction or venue in those courts.

22. Miscellaneous

These Terms, together with the Privacy Policy and any other policies or notices incorporated by reference, constitute the entire agreement between you and NitroMule regarding the Services and supersede prior understandings on the same subject. If any provision is held unenforceable, the remaining provisions remain in full force. Our failure to enforce any right is not a waiver of that right. You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of assets. Notices may be provided by email to the address on your account, by posting on the Site, or by other reasonable means. Headings are for convenience only and do not affect interpretation. Nothing in these Terms creates a partnership, joint venture, or employment relationship between you and NitroMule.
