VARDEX END-USER LICENSE AGREEMENT
Vardex | melbius.com
Last updated: 2026-08-31
Vardex is developed and licensed by The Trustee for THE THREE WANDERERS
TRUST (ABN [add ABN here]) ("we", "us", "our"). Every reference to "we",
"us", or "our" in this Agreement means The Trustee for THE THREE WANDERERS
TRUST.
Purchases are processed by Lemon Squeezy LLC as merchant of record. Lemon
Squeezy is the seller of record for your transaction and is responsible for
payment processing, tax collection, invoicing, and refunds; we are the
licensor of the Software under this Agreement. Your purchase is also subject
to Lemon Squeezy's own buyer terms.
This is a legal agreement between you ("you" or "the user") and us, for
the software product Vardex, including its executable files, associated
components, and documentation (the "Software"). By clicking "I accept"
during installation, or by installing, copying, or otherwise using the
Software, you agree to be bound by the terms of this Agreement. If you
do not agree, do not install or use the Software.
1. LICENSE GRANT
Subject to your compliance with this Agreement, we grant you a
limited, non-exclusive, non-transferable license to install and use
one copy of the Software on a machine you own or control, for as long as
your license key remains active. A license key is tied to one activated
installation ("instance") at a time; deactivating an instance (from
within the Software) frees the key to be activated on another machine.
You may use the Software without a license key in a reduced,
unlicensed mode where offered.
This license is for your own use monitoring networks you are authorized
to monitor (see Section 2). It is not a license to resell, sublicense,
rent, lease, or provide the Software to third parties as a hosted or
managed service without our prior written consent.
2. AUTHORIZED USE ONLY — NETWORK MONITORING SCOPE
Vardex captures and analyses network traffic on the network interface(s)
you configure it to monitor, in order to detect and report potential
security threats. This is powerful software, and using it responsibly is
your obligation, not something the Software enforces on your behalf.
You may only use Vardex to monitor networks and devices that you own,
administer, or are otherwise expressly authorized to monitor (for
example: your own home network, a network belonging to an organization
you work for and have been authorized by that organization to monitor,
or a network you have explicit written permission to monitor). You must
not use Vardex to intercept, capture, or analyse network traffic on any
network, or belonging to any device or person, without such
authorization.
Doing so may violate telecommunications interception, wiretapping,
computer misuse, or privacy laws in your jurisdiction (in Australia,
for example, the Telecommunications (Interception and Access) Act 1979
and the Privacy Act 1988; equivalent laws exist in most other
jurisdictions). You are solely responsible for ensuring your use of the
Software complies with all laws that apply to you, including any
obligations you may have to the people whose network activity the
Software may observe (for example, other members of your household, or
colleagues on a network you administer at work). We are not
responsible for, and disclaim all liability arising from, any use of
the Software that is not authorized as described in this Section.
3. RESTRICTIONS
Except to the extent applicable law expressly permits (and then only to
that extent), you must not: (a) reverse engineer, decompile, or
disassemble the Software; (b) remove, obscure, or alter any proprietary
notice on the Software; (c) use the Software to build a competing
product; or (d) circumvent or attempt to circumvent the Software's
license-activation mechanism.
This Section does not apply to the open-source components described in
Section 4, and nothing in this Agreement restricts, or imposes any
further condition on, the rights you have in those components under
their own licenses. In particular, the packet-capture program
vardex_capture.py and the Scapy library it uses are licensed to you
under the GNU General Public License, version 2, and you may use, copy,
modify, and redistribute them on those terms. See Section 4 and
THIRD-PARTY-NOTICES.txt.
4. THIRD-PARTY COMPONENTS
The Software includes open-source components (including under GPL-2.0,
LGPL-3.0, MPL-2.0, Apache-2.0, BSD, MIT, PSF, and HPND licenses).
Details, required notices, and license texts are in
THIRD-PARTY-NOTICES.txt, distributed alongside
the Software. Where those licenses grant you rights beyond this
Agreement (for example, LGPL-3.0's right to replace a linked library),
this Agreement does not restrict them.
5. THIRD-PARTY SERVICES AND DATA
Vardex offers optional integrations with third-party services —
including AbuseIPDB and GreyNoise (IP threat-intelligence lookups),
MaxMind GeoLite2 (IP geolocation data, obtained by you directly from
MaxMind under MaxMind's own EULA at
https://www.maxmind.com/en/geolite2/eula), Slack and Discord (webhook
notifications you configure), email/SMTP notifications (sent via a mail
server you configure), Lemon Squeezy (license-key activation and
validation), and Anthropic's Claude API (optional AI-generated incident
reports). Where a feature requires your own account, webhook, mail
server, or API key with a provider, your use of that provider's or
server's service is governed by that provider's own terms, not this
Agreement, and we are not responsible for those services' availability,
accuracy, or handling of your data. Data you send to these providers
(for example, an IP address looked up against AbuseIPDB, a notification
sent to a Slack or Discord webhook, an email sent via your configured
mail server, or an incident summary sent to Anthropic for report
generation) is sent directly from your machine to that provider or
server — we do not operate infrastructure that receives or stores this
data.
6. YOUR DATA
Vardex stores captured/derived network event data, configuration, and
threat-intelligence cache locally on your own machine. We do not
collect, receive, or have access to this data. The only data sent to
infrastructure we operate or select is your license key, for
activation/validation with Lemon Squeezy as described in Section 5.
7. DISCLAIMER OF WARRANTY
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
NON-INFRINGEMENT. Vardex is a detection and assistance tool: it does not
guarantee detection of any or all security threats, and must not be
relied upon as your sole means of network protection. Nothing in this
Section excludes or limits any consumer guarantee that cannot lawfully
be excluded or limited under applicable law (including, for consumers in
Australia, the Australian Consumer Law).
8. LIMITATION OF LIABILITY
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY
INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR
ANY LOSS OF DATA, PROFITS, OR REVENUE, ARISING FROM YOUR USE OF OR
INABILITY TO USE THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES. OUR TOTAL LIABILITY UNDER THIS AGREEMENT SHALL NOT
EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE 12 MONTHS PRECEDING
THE CLAIM.
Nothing in this Section excludes, restricts, or modifies any right or
remedy, or any guarantee, warranty, or other term or condition, implied
or imposed by law that cannot lawfully be excluded, restricted, or
modified. For consumers in Australia, our goods come with guarantees that
cannot be excluded under the Australian Consumer Law: you are entitled to
a replacement or refund for a major failure and compensation for any other
reasonably foreseeable loss or damage, and you are entitled to have the
goods repaired or replaced if they fail to be of acceptable quality and
the failure does not amount to a major failure.
9. ENTIRE AGREEMENT
This Agreement, together with THIRD-PARTY-NOTICES.txt where referenced,
is the entire agreement between you and us about the Software, and
supersedes any prior or contemporaneous agreements, understandings, or
representations about the Software.
10. SEVERABILITY
If any provision of this Agreement is found unenforceable or invalid
under applicable law, that provision is limited or removed to the
minimum extent necessary, and the remaining provisions continue in
full force and effect.
11. TERMINATION
This license terminates automatically if you breach this Agreement. On
termination, you must stop using the Software and may be required to
uninstall it. Sections 2, 3, 6-10, and 12 survive termination.
12. GOVERNING LAW
This Agreement is governed by the laws of Victoria, Australia, and
applicable Commonwealth of Australia law, without regard to
conflict-of-law principles.
