Lost Vowels Third-Party Notices

Google

Google provides Android distribution, Google sign-in, Google Mobile Ads, User Messaging Platform consent controls, and signed rewarded-ad verification.

Expo

Expo provides application tooling and push-notification delivery for reminders that players choose to enable.

Advertising SDKs

Advertising is delivered by the Google Mobile Ads SDK, including its User Messaging Platform for consent, under the Google AdMob terms and Google's privacy statement. The React Native bindings, react-native-google-mobile-ads, are published by Invertase under the Apache License 2.0.

Application platform

The application is built with the Expo SDK and React Native, distributed under the MIT licence, together with their open-source dependencies.

Lexical data

English lexical data may be derived from Open English WordNet under the Creative Commons Attribution 4.0 licence. Definitions shown in the game are editorially reviewed and rewritten where required.

Geographic and knowledge sources

Recognisable populated-place data may be derived from Natural Earth, whose vector map data is in the public domain. City and other category candidates may be derived from Wikidata, available under CC0. Broader city coverage may be derived from GeoNames under the Creative Commons Attribution 4.0 licence; GeoNames material is not enabled for production until its licence review is recorded.

Word frequency

Word frequency may be used only as an offline ranking signal. It is not enabled for production until its data and transitive licence notices have been reviewed.

Open-source software

The application includes further open-source packages under their respective licences. Package-level notices remain available with the distributed software and source dependency records.

Source material is prepared offline — the live game never queries a content service while you play.
