What Quotidia owns

These are original works, protected by copyright automatically from the moment they were made:

• The source code — the application, the scheduling logic, the puzzle generators
• The word decks — the selection of words for each language, together with their English glosses, example sentences and tags. This is editorial work, not a copy of any dataset
• The written content — the cultural notes, the pronunciation guidance, the alphabet references and every other piece of explanatory text
• The puzzle themes — how words are grouped, and how the boards are built from them
• The name and visual identity — “Quotidia”, the typography and the colour scheme as used here
• The arrangement — the particular selection and organisation of third-party data, where that arrangement required judgement

What Quotidia does not own

The language databases underneath. Lexique, MorphGNT, the SBL Greek New Testament and the rest are the work of the projects that built them, used under their own licences and credited individually on the credits page. Nothing here claims any right over them, and their licences continue to apply to that material.

What nobody owns

The idea of a language-learning site with a daily word puzzle is a general concept, and general concepts are not protected by copyright. Anyone is free to build something similar. What they may not do is copy this implementation, this content or this name.

Saying so plainly seems better than the usual pretence. What makes Quotidia hard to reproduce is the work in it, not a legal claim over the category.

What you may do

• Use Quotidia to learn, for as long as you like, at no cost
• Screenshot it, write about it, tell people about it
• Copy words and sentences for your own notes or study

What you may not do

• Scrape or bulk-extract the word lists, puzzles or written content
• Republish Quotidia's original content, in whole or in substantial part
• Copy the source code or the visual identity
• Use the name “Quotidia” for a competing language product in a way likely to cause confusion
• Sell, licence or commercially exploit any of the above
