01Scripture and study data
The King James Version
The Bible text in HARK is the King James Version, which is in the public domain. It is bundled inside the app and read offline.
Strong's Hebrew and Greek Dictionaries
The Hebrew and Greek key words on every verse study page come from James Strong's dictionaries (Greek 1890, Hebrew 1894), which are public domain. HARK uses the JSON edition prepared by the Open Scriptures project, which carries a Creative Commons Attribution-ShareAlike (CC BY-SA) notice. In keeping with that notice: this material is from Open Scriptures, it is used under CC BY-SA, and HARK has changed it by selecting only the entries the study pages use and trimming glosses and definitions at sentence boundaries.
King James Version with Strong's numbers
To decide which words on a verse are the significant ones, HARK's build process reads a public-domain KJV tagged with Strong's numbers. It is used only at build time; the Bible you read in the app is HARK's own bundled KJV.
Treasury of Scripture Knowledge
The cross-references on every study page are the Treasury of Scripture Knowledge (R. A. Torrey, 1897, public domain), taken from the SoulLiberty / MetaV copy kept in the bible-crossrefs-dataset repository. The order in which references appear was set at build time using OpenBible.info cross-reference votes (CC BY); no OpenBible data ships in the app.
bible-api.com
The Bible lookup screen fetches verses from bible-api.com, an open, free API serving the public-domain King James Version. Word search runs on the KJV bundled in the app.
02Commentaries
All five commentary voices are public domain. Four were transcribed by sacred-texts.com; HARK's build reads a mirror of those transcriptions kept in the mahabrain repository. Excerpts are cut at sentence boundaries and nothing is rewritten.
- Matthew Henry, Concise Commentary on the Whole Bible (1710).
- Robert Jamieson, A. R. Fausset, and David Brown, Commentary Critical and Explanatory on the Whole Bible (1871).
- John Gill, An Exposition of the Old and New Testaments (1746 to 1763). On the core study books in the app, and on all 66 books through the Commentary Library download.
- Albert Barnes, Notes on the Bible (1834). On the core study books in the app, and on all 66 books through the Commentary Library download.
- Charles H. Spurgeon, The Treasury of David (1869 to 1885), closing every Psalm. Taken from the chspurgeon-tod repository, which is released under CC0; the work itself is public domain.
03Typefaces
- DM Serif Display by Colophon Foundry, distributed through Google Fonts under the SIL Open Font License 1.1. The serif in the app's headings and on this site.
- Plus Jakarta Sans by Tokotype, distributed through Google Fonts under the SIL Open Font License 1.1. The sans-serif in the app's body text and on this site.
04Photography
The forest scenes behind the Atmosphere environments and the Home screen come from photographers on Unsplash, whose license allows free use and asks for credit where we can give it. Two of the files in the app still carry their photographers' names, and we thank them here:
- Ali Kazal, on Unsplash.
- Martin Penot, on Unsplash.
05Music
Every piece of music in HARK was created by HARK's founder, exclusively for the app: the four instrumental playlists and the two songs in the Go Deeper room, "Quiet the Noise" and "Quiet the Noise (Remix)". No third-party music is used.
06Corrections
