Third-party icon licenses
=========================

SheepText bundles icon sets from third parties so you can use them **as stencils
when composing architecture diagrams**. That is the purpose each provider's terms
permit. SheepText does **not** offer these icons as a downloadable icon library or
a general-purpose graphics collection, and provides no "download the whole set"
feature — the icons exist only as diagram vocabulary inside the editor and the
rendered diagrams.

.. admonition:: No endorsement
   :class: important

   The icon authors — including **Amazon Web Services**, **Microsoft**, and
   **Google** — do not sponsor, endorse, approve, or have any affiliation with
   SheepText. Product and company names, logos, and icons are the property of
   their respective owners and are used here only to identify the corresponding
   services within diagrams.

Icons are reproduced **unmodified** apart from lossless packaging (selecting the
upstream SVG, export-size canonicalization, and newline normalization). SheepText
does not recolor, crop, rotate, distort, or otherwise alter the artwork, and you
should not either. Some sets (devicon, Simple Icons, Kubernetes) include brand
logos that remain subject to their owners' trademark rules regardless of the
icon-set license below.

Each set is licensed separately by its author; the terms below govern the icons,
not SheepText's own code.
