Unaffiliated status

YoluBand is an independent language-learning product. It is not affiliated with, endorsed by, or sponsored bythe British Council, IDP: IELTS Australia, Cambridge Assessment English, or any other examination authority. “IELTS” is a registered trademark of those organisations and is referenced in our product solely to describe the exam format that some of our practice features are designed around (nominative fair use).

All practice content in YoluBand is written by our team or generated by AI in publicly-known exam formats, and is not drawn from official examinations or official preparation materials.

External sources we reference

The references below describe the external resources YoluBand draws on. They are grouped by how the resource is used. Passages and cards that are derived from a specific attribution-required source carry an inline attribution line beneath the content itself.

Topic discovery (RSS, titles only)

YoluBand periodically reads the public RSS feeds of the following sites to discover trending English-language exam-prep topics. Only the article titles are used — as topic seeds for our content generator. No third-party article text, excerpt, or passage is stored in our database or passed to the generator.

• IELTS Liz blog (ieltsliz.com) — RSS, titles only.
• British Council IELTS blog (britishcouncil.org/exam/ielts) — RSS, titles only.
• IDP IELTS resources (idp.com) — RSS, titles only.

CEFR alignment

• Council of Europe — Common European Framework of Reference for Languages (CEFR). Publicly published framework. Used internally to map content (A1 through C2) and to report estimated levels back to learners. No CEFR text is reproduced verbatim in YoluBand.
• Cambridge English Profile — English Vocabulary Profile. Free CEFR-aligned vocabulary reference. Used as the basis for our internal CEFR-band check that gates AI-generated passages. The bundled seed word list is a hand-curated subset of widely-published CEFR-aligned vocabulary; replacing it with a full English Vocabulary Profile export requires a free Cambridge registration at englishprofile.org.

Content sources (planned)

The following sources are approved for use in YoluBand content under the licences shown. When a passage or card is derived from one of these, it carries an inline attribution line beneath the content. No content from these sources is currently in our database.

• Voice of America Learning English (learningenglish.voanews.com) — US government public-domain content graded into Beginning / Intermediate / Advanced levels. Public domain.
• Simple English Wikipedia (simple.wikipedia.org) — CC-BY-SA 4.0. When used, the article URL and required attribution string appear in the passage’s attribution badge.
• Mozilla Common Voice (commonvoice.mozilla.org) — CC-0. Used for listening exercise audio. No attribution is required by the licence, but we acknowledge the source here.
• Project Gutenberg (gutenberg.org) — public-domain literature, optionally used for higher-band reading passages.
