small-business grant). Under the ElevenLabs Terms of Service, a paid/commercial
plan grants ownership of and commercial distribution rights to the generated
audio.

IMAGES — OpenAI image generation and Ludo.ai
-------------------------------------------------------------------------------
The illustrations, background patterns, and scene images bundled in the app
(public/patterns/, public/landing/, public/onboarding/, and public/assets/)
were generated with OpenAI's image generation model. Under the OpenAI Terms of
Use, OpenAI assigns to the user all of its right, title, and interest in the
generated output, which may be used commercially.

The JR mascot artwork and animation frames (public/mascot/) were generated with
Ludo.ai. Under the Ludo.ai terms, generated assets are owned by the user and may
be used commercially.

Audio
Voice audio for lesson content and the interface sound effects are generated with ElevenLabs under a commercial plan, made available through the ElevenLabs Grants program.
Pronunciation recordings
Some Tagalog pronunciations in Tagalingo derive from native-speaker recordings sourced from Lingua Libre and Wikimedia Commons, used under their Creative Commons licences. The credits below name the recording and recorder each sourced clip is based on.
We change these recordings before using them: each is either adjusted in volume and trimmed of silence at the start and end, or converted into the Tagalingo voice.

Images
The illustrations, background patterns, and scene art throughout the app are generated with OpenAI's image generation. JR, our jeepney mascot, was created with Ludo.ai.

Tagalingo's dictionary data is derived in part from Wiktionary (via Kaikki.org), with AI-assisted refinement and human review. Wiktionary content is licensed under CC BY-SA 4.0. Accordingly, Tagalingo makes its Wiktionary-derived dictionary content available under the same CC BY-SA 4.0 license.
