# EpicTuner proprietary SDK terms

Copyright (c) 2026 SGK Embedded. All rights reserved except as granted below.

The EpicTuner SDK is **Prerelease**, targeting the 1.0 API. SGK Embedded permits
you to download, use, copy internally, and modify the EpicTuner-authored SDK
headers, tools, templates, and examples to develop, test, and maintain plugins
for EpicTuner. You may distribute and sell your plugins, including compiled SDK
header code and adapted template/example code incorporated into your plugins.
You may distribute your own plugin source, but must direct recipients to SGK
Embedded for the SDK rather than bundling SDK headers, tools, or documentation.

You may not redistribute, mirror, sublicense, or sell the SDK itself, in whole
or in part, including modified SDK copies, except for code incorporated into
plugins as expressly permitted above. The EpicTuner application is separate and
is not licensed for redistribution by these SDK terms. No general trademark or
branding license is granted. All other rights are reserved.

The SDK is provided as is, without warranties of any kind. To the extent allowed
by applicable law, SGK Embedded is not liable for damages arising from its use.

Vendored dependencies retain their own notices and licenses:

- Dear ImGui: `vendor/imgui/LICENSE.txt`.
- GLFW: `vendor/glfw/LICENSE.md`.

These SDK restrictions do not replace or restrict rights granted by those
third-party licenses. Keep their required notices with dependency code and
binaries you redistribute. Example screenshots and synthetic fixtures contain
no customer tunes or captures.

operations remain separate from this SDK release.
