Opura is developed by Facillium. Opura is an independent shorthand practice app designed to help users create, save, revise, and practice shorthand outlines.

Opura is not affiliated with, sponsored by, endorsed by, or officially associated with Gregg Shorthand, the Gregg Publishing Company, McGraw Hill, or any other owner, publisher, or successor associated with historical Gregg shorthand materials, unless otherwise stated in writing.

The term “Gregg shorthand” may be used in Opura descriptively to refer to a shorthand system that users may be learning or practicing. Any trademarks, names, or references remain the property of their respective owners. Opura does not claim ownership over the Gregg shorthand system, historical Gregg publications, or third-party shorthand reference materials.

Some versions of Opura may include optional shorthand reference support. Reference materials are provided only for educational and practice support. Users can turn the reference display on or off in Settings. Opura’s core functionality does not require third-party reference content; users can create and save their own shorthand outlines.

If Opura includes bundled reference images, dictionary excerpts, scans, examples, or lookup images from an external source, those materials must be used only under a valid permission, license, public-domain status, or other lawful basis. The source, license, and attribution should be listed here before public release.

Reference Material Attribution
Optional Gregg shorthand reference support uses public-domain Gregg shorthand materials, specifically the Gregg Shorthand Dictionary by John Robert Gregg, with copyright notices from 1901, 1916, and 1930. Opura is independent and is not an official Gregg shorthand product.

Reference Material Fetching Software
Opura uses or was informed by Richard Liu’s greggdict software, a web searcher and viewer for Gregg shorthand dictionary materials. The greggdict software is licensed under the MIT License, Copyright (c) 2020 Richard Liu, which permits use, copying, modification, distribution, sublicensing, and sale of the software, provided that the copyright notice and license terms are included. The software is provided “as is,” without warranty of any kind. This attribution applies specifically to Richard Liu’s software/code and does not imply that Opura owns, controls, or has been granted rights to any third-party shorthand dictionary publications, scans, reference images, trademarks, or source materials unless separately stated.

User-Created Content
Users retain responsibility for the words, phrases, notes, passages, and drawings they create in Opura. Opura stores this content locally on the user’s device. The developer does not claim ownership over user-created shorthand entries or practice passages.

Apple Technologies
Opura is built using Apple platform technologies including SwiftUI, SwiftData, PencilKit, and iOS/iPadOS system frameworks. Apple, Apple Pencil, iPad, iPhone, iOS, and iPadOS are trademarks of Apple Inc.

App Icon and Visual Design
The Opura app icon, interface design, and original visual identity were created for Opura by Facillium, unless otherwise noted.

Open Source or Third-Party Code
Opura does not currently include third-party open-source libraries outside of Apple system frameworks.
