Visual asset license

The Opi character, stickers, app icons and showcase images

In one line: project code is MIT and dictionaries follow their upstream licenses, but the Opi character, project-drawn stickers, app icons and showcase images are proprietary assets owned by erik.xyz. Personal, non-commercial use of unmodified official builds needs no permission; commercial use requires written authorization.

1. What this license covers

The Opi character and project-drawn expressions: sticker PNG / GIF files, the character's appearance, palette and forms, and the bitmaps/animations generated from them (including per-client build copies and embedded copies). The drawing code remains MIT; this license covers the visual design and generated assets only.
App icons: the same character icon used by Android, Windows, Linux, macOS, iOS and HarmonyOS packages and by the system.
Documentation and showcase images: project showcase images, social previews, form diagrams and images referenced by the README (donation QR codes excluded).
Project-drawn UI assets shipped with the app: for example the Opi panel images in the fcitx5 themes.

2. Not covered

OpenMoji emoji data and the derived emoji table: CC BY-SA 4.0 (credit the OpenMoji project and contributors).
rime_kaomoji_dict kaomoji: MIT (Copyright (c) 2023 aoguai).
Dictionary data: subject to each upstream license; see Dictionary licenses and imports.
Donation QR codes (WeChat / Alipay): not project artwork.
Repository source code: MIT.

3. Allowed

Personal, non-commercial use: use these assets as part of an unmodified official release (an installer or release built by the project) without further permission.

4. Written authorization required

Any commercial use, including use of the assets or modified versions in commercial products, commercial services, advertising, paid content or merchandise.
Redistributing, extracting or modifying the assets in a commercial product.

For commercial licensing, contact erik.xyz.

5. Prohibited

Extracting, redistributing or selling the assets or modified versions as standalone material.
Using modified assets in a commercial product, or removing or hiding copyright and source notices.
Implying that the project author endorses your product in any way.
