Licenses and sources

This page lists only what Biblup uses from others: the Bibles, the context works, the links between passages, the audio voice and the typography. For each work you see the edition, the license, what we do with it and the credit it requires. When all we have is the distributor's own declaration, we say so.

Bible texts

One edition is the base of the stories; two appear beside the English text, depending on your language.

  • World English Bible (WEB)Protestant, 2020 stable text edition (engwebp)

    License:
    Public domain (declared by the distributor)
    What Biblup does:
    It is the English text of the stories and the verse that closes each one, shown as the edition writes it. Biblup's stories are adaptations for people learning English: they are not the WEB and do not use its name.
    What we know:
    Public domain, according to eBible.org, which distributes the edition. This is the distributor's declaration, not legal advice. “World English Bible” is a trademark of eBible.org: a changed text should not use that name.

Context for the stories

The notes and articles behind the Context cards in the lessons and on the story pages.

  • Tyndale Open Study NotesTyndale House Publishers, 2023

    License:
    CC BY-SA 4.0
    What Biblup does:
    The basis of several Context cards: the place, the time, the customs and the names in a passage. We take one fact from the note and rewrite it in plain English, one fact per card; the card names the work and the license. The card text is Biblup's adaptation, not the original note.
    What we know:
    CC BY-SA 4.0, according to the page of the Tyndale Open Resources project, which distributes the notes (“Creative Commons Attribution-ShareAlike 4.0 International License”). This is the distributor's declaration, not legal advice. The license asks for credit and for adaptations to carry the same license: the credit is below, and the cards made from the notes carry the same license.

  • WikipediaEnglish Wikipedia, articles read at a fixed revision (permalink)

    License:
    CC BY-SA 4.0
    What Biblup does:
    Fills in the Context cards where the free works do not cover a subject. Each article is read at a fixed revision (permalink), and only one short fact is used, rewritten in plain English and cited on the card. It is the lowest-ranked source we use.
    What we know:
    CC BY-SA 4.0 and GFDL, according to the Wikimedia Foundation Terms of Use, which say that reusers may follow either license or both. We follow CC BY-SA 4.0. This is the distributor's declaration, not legal advice. Wikipedia is written by volunteers and changes all the time: that is why we fix the revision of each article. The license asks for credit and for adaptations to carry the same license.

  • The Jewish EncyclopediaIsidore Singer (ed.), Funk & Wagnalls, 1901–1906

    License:
    Public domain (declared by the distributor)
    What Biblup does:
    A source of short notes on the customs and daily life of the people of the Bible, such as bread and the blessing said over it, on the Context cards. It is a work from 1901–1906: we use only customs and facts, never absolute dates, archaeological finds or “what scholars think today”.
    What we know:
    Public domain, according to JewishEncyclopedia.com, which publishes the work (“public domain”). This is the distributor's declaration, not legal advice. The work is old and reflects the view of its time: that is why it supports only customs and facts, and never mistakes tradition for a historical event.

Cross-references

The links between passages that appear in reading mode and in each lesson's Help.

  • OpenBible.info — Bible Cross Referencescross-references.zip (12 Oct 2026)

    License:
    CC BY 4.0
    What Biblup does:
    It shows, below a verse and in the lesson's Help, other passages linked to it, with the text of the World English Bible. We use only the passage pairs and the votes in the file, and keep the most-voted links for each verse. It is read-only.
    What we know:
    CC BY, according to the OpenBible.info page, which distributes the data; it cites version 4.0 of the license. This is the distributor's declaration, not legal advice. The author says the data comes mainly from the Treasury of Scripture Knowledge, which is in the public domain, and that the votes are from users. We use only the passage pairs and the votes: the Bible text shown does not come from there.

Audio

The voice that reads English aloud.

  • Piper — en_US-lessac-mediumen_US · medium

    License:
    MIT (label on the voices repository)
    What Biblup does:
    It reads the English of the lessons aloud. It is a synthetic voice, generated on Biblup's server with Piper, not the recording of a person.
    What we know:
    The Piper voices repository page carries an MIT license label for the repository; the model card of this voice (“lessac”) names no license for the model. The data it was trained on (Lessac Technologies and Voice Factory, published by the University of Edinburgh) is under a research license (“Research Licence Agreement”), separate and its own (the “Training data” link). This page does not say what that license allows and does not summarize its terms: read the text behind the link.

Typography

Served by Biblup itself, without asking another site for anything.

SIL Open Font License 1.1, according to the OFL.txt file that ships with the font in Biblup and the project's repository. The license asks that copies of the font carry the copyright notice and the license text: the notice is below and the text is behind the link.

How we give credit

Five rules that apply to every work on this page.

  1. Credits live here

    The edition, license and credit of each work are on this page. The full credits are not repeated in the lessons: there, the Context card only names the work and the license of what it shows.

  2. A “Credits” link beside the text

    Where a Bible appears beside the English, the “Credits” link leads to the Bible versions page, with the edition, the license and the authors.

    See the Bible versions

  3. Bible text is not altered

    We show each Bible without changing the words. What we do is align the verse numbering with the WEB's.

  4. What is ours carries our name

    The stories, the exercises and the explanations are produced by Biblup to teach English. They are not the WEB or the other editions and do not use their names.

  5. We say what we know

    When the only basis is the license the distributor declares, we write “according to the distributor”. That is not legal advice and may change if the distributor changes its page.

Every page and license cited here was opened and read on the date shown for each work. Distributors can change their terms later: the date says when we checked.
