What These Terms Cover
These Terms of Use apply to your use of NOTBOX hardware, firmware, software features, local web interface, update services, the HENcloud management platform and accounts, website content, and API documentation provided by Heller Networks LLC ("Heller Networks," "we," "our," or "us").
By using NOTBOX or related services, you agree to these terms.
Authorized Use Only
NOTBOX is a network testing and impairment appliance. You agree to use it only on networks, devices, and systems that you own or are authorized to test.
- Do not use NOTBOX to disrupt or inspect networks without permission.
- Do not use NOTBOX for unlawful activity.
- You are responsible for how the device is configured and where it is inserted into a network.
- If you automate the device through its local API, including with AI agents, you are responsible for the API tokens you issue and for everything done with them.
Product Purpose and Operational Responsibility
NOTBOX can intentionally introduce latency, packet loss, jitter, bandwidth limits, and other network conditions for testing. These settings may interrupt traffic or cause systems to behave unexpectedly.
You are responsible for:
- Using the device in a safe test environment
- Verifying port placement (MGMT / UPLINK / DOWNLINK / LOCAL) before applying tests
- Avoiding use on production systems unless you intentionally want to test production behavior
Ownership and License
Heller Networks retains ownership of NOTBOX software, firmware, design, branding, and related intellectual property, except for third-party/open-source components that are governed by their own licenses.
When you purchase a NOTBOX device, you own the hardware. The embedded firmware and software are included for use on the device and may not be separated, extracted, or redistributed independently, except where permitted by applicable open-source licenses (see below).
- You may use the product for its intended purpose: network testing, validation, and diagnostics.
- If you transfer or sell the physical device, the right to use the included software transfers with it.
- You may not redistribute the firmware or software independently from the device, except where allowed by applicable open-source licenses.
- You may not remove product branding, legal notices, or attribution information where prohibited by law or license.
Open Source Components
NOTBOX includes open-source software components. Those components are licensed under their respective open-source licenses, which continue to apply.
Open-source notices and license disclosures are on our Open Source page and in the device's own license listings.
Reverse Engineering and Proprietary Code
You may not reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of Heller Networks proprietary software components, except to the extent that applicable law expressly permits such activity regardless of this restriction.
This restriction does not apply to open-source components included in NOTBOX, which remain subject to their own license terms.
Firmware Updates and Device Services
NOTBOX may check for and install firmware updates when you choose to use the update feature. Firmware updates may improve reliability, fix bugs, change behavior, or update disclosures/documentation.
- Update availability may vary by device model and firmware version.
- We may stop publishing updates for older releases or hardware over time.
- You are responsible for testing updates before broad deployment in your environment.
Compatibility and Third-Party Environments
NOTBOX is designed to work with common networking equipment and storage environments, but compatibility can vary based on your routers, switches, clients, NAS devices, SMB/NFS configuration, firewall rules, and other third-party systems.
We do not guarantee compatibility with every network topology, storage server implementation, or operating environment.
Orders and Payment
NOTBOX is sold on this website for delivery within the United States. Prices are in US dollars per unit and may change at any time; the price shown at checkout is the price you pay. Sales tax is calculated and collected at checkout where required.
- Online orders are limited to three units. For larger orders, request a quote and we invoice you directly.
- Payment is processed by Stripe. We accept major cards, Apple Pay, Google Pay, and US bank debit (ACH). Card and bank details are entered with Stripe and are never stored by us.
- Bank payments take up to 4 business days to clear. We ship after the payment clears.
- An order is accepted when we ship it. We may cancel an order before shipping, for example if the item is unavailable, the address is outside the United States, or the payment is flagged as high risk. In that case you are refunded in full.
- Ownership of the hardware and the risk of loss pass to you when the carrier delivers the package.
- Stripe emails your receipt. We email a tracking number when your order ships.
Warranty and Disclaimer
NOTBOX hardware is covered by a limited warranty as described in our Warranty and Returns policy.
Unless a separate written warranty applies to your purchase, NOTBOX software and firmware are provided on an "as is" and "as available" basis.
For NOTBOX hardware, implied warranties are limited to the duration of the Limited Hardware Warranty. For software, firmware, HENcloud, and other services, Heller Networks disclaims implied warranties, including merchantability, fitness for a particular purpose, and non-infringement, to the maximum extent allowed by law.
This section does not override any non-waivable consumer rights that apply in your jurisdiction.
Limitation of Liability
To the maximum extent allowed by law, Heller Networks is not liable for indirect, incidental, special, consequential, or punitive damages, including lost profits, lost data, business interruption, or downtime resulting from use or misuse of NOTBOX.
To the extent liability cannot be excluded, Heller Networks' total liability will be limited to the amount you paid for the specific NOTBOX unit or related service giving rise to the claim.
Indemnification
You agree to defend and indemnify Heller Networks against claims, damages, and costs that arise from your use of NOTBOX or HENcloud on networks or systems you were not authorized to test, or from your violation of these Terms.
Data, Privacy, and Network Information
Depending on how you use the device, NOTBOX may process network test traffic, packet captures, connection metadata, and configuration data locally on the device, on network storage you configure, or through HENcloud if you connect the device.
Update checks, activation workflows, and website contact forms may communicate with Heller Networks infrastructure. If you connect the device to HENcloud, it also maintains an outbound connection to HENcloud. You are responsible for understanding your own data handling obligations when using packet capture or network diagnostics in your environment.
For information about website contact forms and hosted service data handling, see our Privacy Policy.
HENcloud Accounts
HENcloud is an optional cloud platform for managing NOTBOX devices. It is not required to use a NOTBOX, and this section applies only if you create an account and connect a device.
You are responsible for the accuracy of your account information, for keeping your credentials secure, and for the actions of team members you invite. Access within an organization is role-based (owner, admin, or viewer). Viewers may operate device testing features but cannot manage the organization, fleet, or security settings; admins may also manage devices and team members; and organization owners are responsible for ownership and access decisions.
The data your devices report to HENcloud belongs to you. We use it only to provide the service, and it is removed when the organization is deleted, as described in the Privacy Policy. You may disconnect a device from HENcloud at any time, returning it to local-only operation. You may delete your account after confirming your password unless you are the only owner of an organization; in that case, you must first make another member an owner or delete the organization. An organization must have its devices removed before an owner can delete it. We may suspend or terminate a HENcloud account for the reasons described in Termination or Suspension below.
Returns, Support, and Service Expectations
Unless otherwise stated in writing, NOTBOX is sold as a self-managed appliance and does not include a guaranteed response time, managed service plan, or continuous support availability.
Support is provided on a reasonable-effort basis through published contact channels. Return, refund, and replacement handling may differ if you bought through a reseller.
For purchases made directly from Heller Networks, non-defective returns are accepted within 30 days of delivery with prior authorization. There is no restocking fee; you pay the return shipping. A unit that arrives defective is replaced or refunded at no cost to you. The full policy is on the Warranty and Returns page.
If you purchased through a reseller or marketplace, that seller's return policy may also apply.
Termination or Suspension
We may suspend or terminate access to hosted services (including HENcloud accounts, update endpoints, or support systems) if necessary for maintenance, abuse prevention, legal compliance, or service protection.
These Terms do not grant a guaranteed minimum service term for hosted update infrastructure unless separately agreed in writing.
Changes to These Terms
We may update these Terms from time to time. The latest version will include an updated "Last updated" date. Continued use of the product or related services after changes are published means you accept the updated Terms.
Export Compliance
You agree to comply with all applicable export control laws and regulations, including United States export controls, when using or transferring NOTBOX products.
Authority
By using NOTBOX or related services, you represent that you have the legal authority to agree to these Terms on behalf of yourself or the organization you represent.
Governing Law and Venue
These Terms are governed by the laws of the State of Michigan, USA, without regard to conflict-of-law rules. Unless applicable law requires otherwise, disputes will be handled in the appropriate state or federal courts located in Michigan.
Severability
If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or removed to the minimum extent necessary, and the remaining provisions will remain in full effect.
Entire Agreement
These Terms, together with the Privacy Policy and Warranty & Returns policy, constitute the entire agreement between you and Heller Networks regarding NOTBOX, and supersede any prior agreements or representations.
