# Kismet — End User License Agreement

**Effective: 2026-05-07**

This End User License Agreement ("EULA") is a contract between you and
**Individual Entrepreneur Artem Tarasov, registration № 72930421, 002,
5 Deghatan str., Yerevan, Republic of Armenia** ("Kismet," "we," "us")
for use of the Kismet plugin for Unreal Engine (the "Plugin"). By
installing, copying, or using the Plugin you accept this EULA. If you
do not accept it, do not install or use the Plugin.

This EULA supplements — and is incorporated into — the Kismet Terms of
Service at https://kismetai.io/terms ("Terms"). Capitalised terms not
defined here have the meanings given in the Terms. If anything in this
EULA conflicts with the Terms, the Terms control.

---

## 1. Beta status

The Plugin is currently in **beta**. It is provided for evaluation, may
be unstable or incomplete, and may be changed, suspended, or discontinued
at any time. Keep your work under source control and back up your project
before letting the Plugin act on it.

## 2. Account requirement

The Plugin requires a Kismet account. You authenticate the Plugin through
a device-code flow at https://kismetai.io. The Plugin will not run agent
operations until your account is linked.

## 3. Licence grant

Subject to your continuing compliance with this EULA and the Terms, we
grant you a **limited, revocable, non-exclusive, non-transferable,
non-sublicensable** licence to install and use the Plugin internally with
Unreal Engine for as long as you have an active Kismet account. The
licence is per-user; do not share your account or Plugin token.

The Plugin is **licensed, not sold**. We retain all right, title, and
interest in the Plugin. No rights are granted to you by implication,
estoppel, or otherwise.

## 4. Restrictions

You will not, and will not let anyone else:

- Reverse engineer, decompile, disassemble, or otherwise attempt to derive
  the source code of the Plugin, except to the extent applicable law
  expressly permits despite this restriction.
- Remove, alter, or obscure any copyright, trademark, licence, or other
  proprietary notices.
- Resell, sublicense, rent, lease, or commercially redistribute the
  Plugin, your Kismet account, or your Plugin token.
- Use the Plugin or its outputs to train, fine-tune, distil, or benchmark
  a competing AI product, model, or feature.
- Use the Plugin to generate or assist with code you do not have the
  rights to use, or in violation of any law or third-party right.
- Bypass authentication, telemetry redaction, rate limits, or other
  protective mechanisms.

The full acceptable-use list is in our Acceptable Use Policy at
https://kismetai.io/aup (also incorporated into §5 of the Terms), and
applies here. It mirrors Anthropic's Usage Policy
(https://www.anthropic.com/legal/aup) because the Plugin calls Claude
under your own API key.

## 5. Bring your own key (BYOK)

The Plugin calls a third-party AI provider (currently Anthropic) directly
from your machine using an API key **you** provide. Your relationship with
that provider is governed by their terms and privacy policy. We are not a
party to that relationship and have no contract or payment relationship
with the provider on your behalf. You are responsible for all charges
your provider invoices you for. Your API key is stored locally in your
operating-system credential store and is never transmitted to or proxied
through Kismet servers.

## 6. AI-generated suggestions

The Plugin's agent loop generates Blueprint nodes, edits, code,
explanations, and other outputs ("Suggestions"). Suggestions are produced
by a probabilistic AI model. They may be wrong, incomplete, contain bugs,
mis-cite documentation, or reflect biases in the model's training data.

**Factual assertions in Suggestions should not be relied upon without
independently verifying their accuracy, as they may be false, incomplete,
misleading, or not reflective of recent events.** Suggestions may contain
content that does not reflect the views of Anthropic or of Kismet.

**You are solely responsible** for reviewing every Suggestion before
relying on it, and for the impact of any change the Plugin makes on your
machine — including data loss, broken builds, or corrupted assets.

We claim no ownership of Suggestions. To the extent we have any rights in
a Suggestion as delivered to you, we **assign those rights to you**, free
of charge, and keep no licence to them.

### 6.1 High-risk use cases

If you use a Suggestion to inform a consumer-facing decision in a
high-risk domain — including legal advice, medical or mental-health care,
insurance underwriting, financial or credit decisions, employment or
housing decisions, academic scoring or admissions, or journalism intended
for external publication — you must (a) keep a qualified human in the
loop and (b) clearly disclose AI involvement to the affected end-users.
This obligation comes from the AI provider's Usage Policy and is
reproduced in our Acceptable Use Policy §3 (https://kismetai.io/aup).
Kismet itself is a developer tool and is not licensed for these
scenarios; if you build a downstream product that is, the obligation sits
with you as that product's operator.

## 7. Telemetry

The Plugin sends usage telemetry to your Kismet account. Telemetry is
split into four categories — Runs, Tool calls, Errors, Crashes — that you
control independently in **Settings → Telemetry** on the dashboard. With
all four off, only essential heartbeat events flow.

Blueprint contents are redacted at our ingestion endpoint before storage.
For implementation details see https://kismetai.io/security.

## 8. Auto-update

The Plugin checks our release manifest at start-up to discover newer
versions. The check sends only your Plugin version, OS family, Unreal
Engine version, and machine ID. Update download and installation are
**user-initiated**; we do not silently push code to your machine. You can
disable update checks in the Plugin settings.

## 9. Open-source and third-party components

The Plugin links against Unreal Engine modules provided by Epic Games,
Inc. and may include other third-party components. Attribution and
licence notices for those components are in the `NOTICE.md` file shipped
with the Plugin. Your use of Unreal Engine itself is governed by Epic's
Unreal Engine End User License Agreement, separate from this EULA.

Kismet is an independent product. It is not affiliated with, endorsed by,
or sponsored by Epic Games, Inc. Unreal Engine and Blueprint are
trademarks of Epic Games, Inc.; their use here is descriptive.

## 10. Term and termination

This EULA takes effect when you first install or use the Plugin and
continues until terminated. You may terminate it at any time by
uninstalling the Plugin and requesting account deletion from your
dashboard. We may suspend or terminate it for material breach of this
EULA or the Terms, to comply with law, or if the Plugin is discontinued.

On termination: your licence ends immediately, you must stop using and
uninstall the Plugin, and the data-deletion schedule in §10 of the
Privacy Policy applies. Sections 4, 6, 11, 12, 13, 14, and 15 survive.

## 11. Disclaimer of warranties

THE PLUGIN AND ALL SUGGESTIONS ARE PROVIDED "AS IS" AND "AS AVAILABLE,"
WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. To the maximum extent
permitted by law we disclaim all warranties, including merchantability,
fitness for a particular purpose, non-infringement, accuracy, and quiet
enjoyment. We do not warrant that the Plugin will be uninterrupted,
error-free, or secure, or that Suggestions will be correct, complete, or
fit for any purpose. Some jurisdictions don't allow exclusion of certain
implied warranties; to that extent the exclusions in this section may not
apply to you.

## 12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL KISMET BE LIABLE
FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR
PUNITIVE DAMAGES, INCLUDING LOST PROFITS, LOST DATA, BUSINESS
INTERRUPTION, OR LOSS OF GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY.

OUR AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE PLUGIN IN ANY
TWELVE-MONTH PERIOD IS LIMITED TO THE GREATER OF (A) THE FEES YOU PAID US
DURING THAT PERIOD (CURRENTLY ZERO) OR (B) ONE HUNDRED UNITED STATES
DOLLARS (US$100). These limits are an essential part of the bargain.

## 13. Export controls and sanctions

You will comply with applicable export-control and sanctions laws. You
confirm that you are not located in, under the control of, or a national
or resident of, a country or territory subject to a comprehensive embargo
by Armenia, the United States, the European Union, or the United
Kingdom; and that you are not on any restricted-party list maintained by
those jurisdictions.

## 14. Governing law and disputes

This EULA is governed by the laws of the **Republic of Armenia**, without
regard to conflict-of-laws principles. The courts of **Yerevan, Republic
of Armenia** have exclusive jurisdiction, subject to a 60-day informal-
resolution period and to mandatory consumer-protection rights you may
have in your home jurisdiction (see §16 of the Terms).

## 15. Miscellaneous

- **Entire agreement.** This EULA, together with the Terms, Privacy
  Policy, and Data & Security page, is the entire agreement between you
  and us about the Plugin.
- **Severability.** If any provision is unenforceable, the rest stays in
  effect.
- **Assignment.** You may not assign this EULA without our written
  consent. We may assign it to an affiliate, successor, or acquirer.
- **No waiver.** Our failure to enforce a right is not a waiver of it.
- **Updates to this EULA.** We may update this EULA when our practices
  change. The effective date at the top reflects the last change.
  Material changes will be announced at least 14 days before they take
  effect; continued use after that means you accept the updated EULA.

---

Plain-English summary (not a substitute for the EULA above): you get a
personal, revocable licence to use the Plugin while you have an active
Kismet account; you bring your own AI key; the Plugin is a beta tool —
review what it does to your project; outputs belong to you; we keep the
Plugin's code; disputes go to Yerevan under Armenian law, consumer rights
aren't affected.
