Glance Deck — Open-Source and Third-Party Notices
Last updated: May 17, 2026
The Glance Deck product, website, and web-based firmware installer include third-party open-source software. We are grateful to the open-source community. Each component below is the property of its respective copyright holders and is provided under its own license. The relevant license grants and notices below apply to those components only and not to the proprietary Glance Deck Software. Nothing in the Glance Deck Terms of Service or EULA limits the rights you have under these open-source licenses with respect to the components they cover.
The complete, unmodified text of every license below is published at glancedeck.com/legal/THIRD_PARTY_LICENSES.txt. Because the firmware is distributed as a binary image that cannot itself carry a text file, that web-hosted copy — linked from the Web Installer at install time and from the on-device website pointer — is how these notices accompany the software. A copy is also available on request at support@glancedeck.com.

| NimBLE-Arduino | © h2zero and the Apache NimBLE / Apache Mynewt contributors | Apache-2.0 |
| ArduinoJson | © Benoît Blanchon | MIT |
| Adafruit STMPE610 (certain board variants only) | © Adafruit Industries | MIT |
| Arduino core for ESP32 (arduino-esp32) | © Espressif Systems and contributors | LGPL-2.1-or-later |
| ESP-IDF and its components, including Mbed TLS | © Espressif Systems; © Arm Limited and Mbed TLS contributors | Apache-2.0 |

Note: Some Espressif-managed components are present in the source tree but are excluded from the shipped firmware by build configuration and are not distributed in the product binaries.
1.1 LGPL-2.1 Written Offer (arduino-esp32)
The firmware statically incorporates the Arduino core for ESP32, licensed under the GNU Lesser General Public License, version 2.1 (LGPL-2.1). In accordance with that license, GT Media will, for any recipient of a Glance Deck device or firmware image, make available the LGPL-licensed library source code and the Glance Deck object files (or other materials) sufficient to allow you to modify the LGPL-covered portions and relink them with the rest of the firmware.
To obtain these materials, contact support@glancedeck.com referencing
"Glance Deck LGPL request." We may charge no more than a reasonable cost for the
physical act of distribution. This offer is valid for at least three (3) years
from your receipt of the firmware. The corresponding source for the LGPL-covered
library is also available from its upstream project (Espressif Systems,
arduino-esp32).
1.2 Font Awesome Free — Required Attribution (CC BY 4.0)
The Glance Deck firmware displays icons derived from Font Awesome Free, version 7.2.0. Font Awesome Free is dual/triple-licensed by component; the license stamped by Font Awesome into every source icon is reproduced verbatim below:
Font Awesome Free 7.2.0 by @fontawesome — https://fontawesome.com License — https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) Copyright 2026 Fonticons, Inc.
Only the icon artwork is used in this product (no Font Awesome webfont and no Font Awesome code are distributed), so the governing license for the bundled material is the Creative Commons Attribution 4.0 International License (CC BY 4.0), https://creativecommons.org/licenses/by/4.0/. The SIL OFL 1.1 (fonts) and MIT (code) components of Font Awesome are not used here. This is not Font Awesome 4.x (which is SIL OFL 1.1 + MIT); the bundled assets are Font Awesome Free 7.2.0 and are governed by the notice above.
Modifications (required CC BY 4.0 disclosure): the original Font Awesome SVG icons have been modified by GT Media for embedded rendering — converted to flattened polygon-outline vertex data, curve-flattened, re-scaled, and normalized to a fixed coordinate space. The icons as shipped are a modified form of the originals; Fonticons, Inc. does not endorse GT Media or this product.

Build-time-only tooling (e.g., TypeScript, Tailwind CSS, PostCSS, Autoprefixer — all MIT/Apache-2.0/permissive) is used to create, but is not distributed in, the website or firmware.
