Open-source licences

Teatroo is built with the help of open-source software and open data. We are grateful to the people who make them and share them. This page names them and links to their licences.

1. Font

The app and this website use the font Noto Serif. Copyright 2022 The Noto Project Authors (github.com/notofonts/latin-greek-cyrillic). This font is licensed under the SIL Open Font License, Version 1.1. The licence is available at openfontlicense.org.

2. Software

The app uses open-source software components, among them the Kotlin language and its libraries and the Android Jetpack libraries, together with open-source libraries for the interface, for storing data on the phone, for loading pictures and for working with the network. These components are licensed under the Apache License, Version 2.0. The licence is available at apache.org/licenses/LICENSE-2.0.

The app also uses services of Google (Firebase and Google Play services), which are provided under Google’s own terms.

3. City names

The names of cities in different languages come from GeoNames (geonames.org), licensed under the Creative Commons Attribution 4.0 licence (creativecommons.org/licenses/by/4.0). The data was shortened and put into another format for the app.

4. What these licences cover

Each licence covers the component it belongs to, not the Teatroo app as a whole. The components are provided by their authors without warranty, as their licences say.
