IP Policy & Source Texts

Cammino’s content is built from texts in the public domain or under open licenses. We believe sacred tradition belongs to the faithful, and we pay royalties only where the law explicitly requires.

Scripture

• Douay-Rheims 1899 American Edition — public domain. Our English Catholic scripture throughout the product.
• Clementine Vulgate (1592) — public domain. Our Latin scripture.
• We do not use the Nova Vulgata (1979) or the NAB or the RSV-CE — these remain under copyright at launch and we respect that.

Liturgical calendar

Via romcal, MIT-licensed. Novus Ordo (universal) at launch; 1962 calendar coming post-MVP.

Lives of the saints

Seed material is drawn from pre-1928 editions of Butler’s Lives of the Saints (public domain) and augmented by AI generation reviewed by a theological-review agent against the Catechism of the Catholic Church, with human spot-checks.

AI-generated content

Graded-reader lessons, vocabulary lists, and saint biographies are AI-drafted from the sources above and reviewed through our Censor (theological-accuracy) and linguist pipelines. Every lesson carries immutable provenance — which source, which model version, which reviewer, which approval date. Our derivative works are original IP.
