Licences & Attribution

Last updated 1 September 2026

Tvara stands on a lot of other people's work. This page credits it.

Food data

Our food database is assembled from public national food-composition datasets and hosted by us. Each source keeps its own licence:

Icons

App and website icons are from Tabler Icons, MIT licence, © Paweł Kuna. On iOS, some system glyphs are Apple SF Symbols, used under Apple's terms and not redistributed.

Typefaces

This website uses Clash Display and Switzer by the Indian Type Foundry, served by Fontshare under the ITF Free Font Licence. The app itself uses the operating system's own typefaces — SF Pro on iOS, Roboto on Android — and bundles no fonts.

Maps

Route maps are rendered with MapLibre GL (BSD-3-Clause), with tiles from MapTiler and map data © OpenStreetMap contributors, available under the Open Database Licence.

Software

Tvara is built with React Native and on a large amount of open-source software, almost all of it under the MIT licence, with a handful of Apache-2.0 components. The licence texts below govern that software.

A complete, current list of every package we ship, with its copyright holder and licence, is available on request from hello@tvara.health.
