Licenses & Attributions
Kapy Notes is built on other people's work. This page names it.
Exchange-rate data
Currency conversion uses rates from Frankfurter, with ExchangeRate-API as a fallback. Both providers require attribution for their open endpoints; the app shows the provider in use under Settings → Exchange rates, and tapping it opens their site. Rates are supplied by those services, not by us.

The app
Kapy Notes is built with Flutter and Dart, both BSD-licensed by Google, together with a small number of open-source Dart packages: path_provider, http and package_info_plus (BSD-3-Clause, by the Flutter team), url_launcher (BSD-3-Clause), window_manager, hotkey_manager and auto_updater (MIT), and material_ui (BSD-3-Clause). Each is used unmodified, under its own license.
The desktop builds update themselves using Sparkle on macOS, copyright Andy Matuschak and contributors, and WinSparkle on Windows, copyright Vaclav Slavik. Both are MIT-licensed and are included unmodified.
If you need the full license text for any of them, email hello@kapynotes.com and we will send it.
