Third party notices

D-REC includes and uses the following third party work. Their licences are reproduced here as those licences require.

Typefaces

D-REC's interface is set in Archivo and IBM Plex Mono. Both are licensed under the SIL Open Font License, Version 1.1, and both are redistributed with the app in subsetted WOFF2 form. Subsetting strips the name table where a font normally carries its own notice, which is why the notice lives here instead.

PREAMBLE

The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply to any
document created using the fonts or their derivatives.

DEFINITIONS

"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may include
source files, build scripts and documentation.

"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).

"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).

"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.

"Author" refers to any designer, engineer, programmer, technical writer or
other person who contributed to the Font Software.

PERMISSION & CONDITIONS

Permission is hereby granted, free of charge, to any person obtaining a
copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:

1) Neither the Font Software nor any of its individual components, in
Original or Modified Versions, may be sold by itself.

2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or in
the appropriate machine-readable metadata fields within text or binary
files as long as those fields can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any Modified
Version, except to acknowledge the contribution(s) of the Copyright
Holder(s) and the Author(s) or with their explicit written permission.

5) The Font Software, modified or unmodified, in part or in whole, must be
distributed entirely under this license, and must not be distributed under
any other license. The requirement for fonts to remain under this license
does not apply to any document created using the Font Software.

TERMINATION

This license becomes null and void if any of the above conditions are not
met.

DISCLAIMER

THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF
COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,

DEALINGS IN THE FONT SOFTWARE.

Speech recognition, in the browser

On the web, D-REC runs speech recognition through Transformers.js (Apache License 2.0) and ONNX Runtime Web (MIT License), loaded from a public CDN at the moment they are used rather than redistributed inside D-REC. The speech models themselves are OpenAI's Whisper weights (MIT License), fetched the same way and cached by your browser.

Because these are fetched rather than bundled, D-REC is not redistributing them; they are named here so it is clear what runs on your machine and where it comes from.

The desktop applications

The Mac and Windows applications are built on Electron (MIT License), which embeds Chromium and Node.js and their many contributors' licences. Those licences ship inside the application itself as LICENSE.electron.txt and LICENSES.chromium.html, alongside the program.

On the iPhone

Speech recognition and summaries use Apple's own on-device frameworks, provided as part of iOS. The app shell uses Capacitor (MIT License).

The welcome recording

The spoken take D-REC opens with was synthesised for Knight AI+AV LLC using Fish Audio. It is not a recording of a person.
