Licenses¶
Melanite is © 2026 Toshikatsu Masui. The app stands on more than 450 pieces of open source software, and it ships their copyright notices and full license texts inside the application.
End user license agreement¶
Melanite carries no EULA of its own. Your use of it is governed by the standard agreement of the store you obtained it from.
| Obtained from | Governing agreement |
|---|---|
| Mac App Store | Apple's Licensed Application End User License Agreement |
| Microsoft Store | Standard Application License Terms |
Viewing them in the app¶
Open Settings → Licenses.
- The top shows the Melanite version and its copyright notice
- Below it is every package the app is built with (name / version / license)
Select a package name to reveal its upstream URL and full license text in place.
The filter box matches license names as well as package names, so typing MPL-2.0
or BSD narrows the list to just those.
The same list is available as plain text in the repository as THIRD-PARTY-NOTICES.md.
Main components¶
| Component | Used for | License |
|---|---|---|
| Tauri | Application shell (window, IPC) | Apache-2.0 OR MIT |
| Svelte | Rendering the UI | MIT |
| CodeMirror 6 | The note editor | MIT |
| SQLite | The library database | Public domain |
| PDFium | PDF thumbnails | BSD-3-Clause / Apache-2.0 |
| Leaflet | Drawing the map | BSD-2-Clause |
| marked | Markdown preview | MIT |
| DOMPurify | Sanitizing the preview | Apache-2.0 |
| resvg | SVG thumbnails | Apache-2.0 OR MIT |
The vast majority — over 400 of them — are MIT, Apache-2.0, or BSD-style grants. All of these require the copyright notice and full license text to travel with the distributed binary, which is exactly what the in-app list is for.
Map attribution¶
The tiles shown in the map view come from OpenStreetMap.
- Map data is © OpenStreetMap contributors, available under ODbL 1.0
- The tile images are available under CC BY-SA 2.0
This attribution is shown permanently in the corner of the map view. Melanite neither stores nor redistributes OpenStreetMap data; tiles are fetched only while the map view is open.
Opening the map view makes a network request
Fetching tiles requires a connection to the OpenStreetMap tile server. Your location data itself stays inside the library and is never sent anywhere.
Melanite's own source code¶
Melanite is not open source. Its source code is not published; the notices on this page cover the software it uses.
A few dependencies (the MPL-2.0 ones) carry an obligation to make the source of those files available. Their upstream URLs are listed in the in-app list, and unmodified sources can be obtained there — Melanite does not modify any of them.
