CombraCombra — Third-Party Licenses
Last updated: 22 August 2026
Combra is built on open-source work. Most of it runs on our servers, but a few components are files your browser downloads from our own domain — two typeface families and an icon font. Serving a copy is redistribution, and the licenses on those components require their notice to travel with the copy. This page is that notice in readable form; the full license text sits next to each set of files, at the links in the tables below.
None of the projects listed here has reviewed, endorsed, or sponsored Combra. They are listed because we use their work, not because they are connected to us.
Typefaces
Both families are licensed under the SIL Open Font License, Version 1.1, which permits bundling and redistribution with software provided each copy carries the copyright notice and the license. We serve both unmodified, so the OFL's Reserved Font Name condition does not come into play.
| Typeface | Where it is used | Copyright | License text | Upstream project |
|---|---|---|---|---|
| IBM Plex Sans and IBM Plex Mono | The product interface and the marketing site | © 2017 IBM Corp., with Reserved Font Name "Plex" | /vendor/ibm-plex/OFL.txt | IBM Plex on GitHub |
| Roboto | The legal pages, the sign-in screens, and the Material 3 surfaces of the product | © 2011 The Roboto Project Authors | /vendor/roboto/OFL.txt | Roboto on GitHub |
Roboto and the interface's IBM Plex faces are fetched from Google Fonts when we build the site, not when you load it. The font files are then served from our own domain like any other asset — which is why they are on this list. Your browser makes no request to Google Fonts, or to any other font host, while using Combra.
Icons
| Component | Where it is used | Copyright | License | License text | Upstream project |
|---|---|---|---|---|---|
| Phosphor Icons | Every icon in the product, served as an icon font | © 2020 Phosphor Icons | MIT | /vendor/phosphor-icons/LICENSE | Phosphor Icons on GitHub |
Analytics script
| Component | Where it is used | Copyright | License | Upstream project |
|---|---|---|---|---|
| Umami | The marketing site's page-view counter, served from our own Umami instance | © 2022 Umami Software, Inc. | MIT | Umami on GitHub |
Umami is self-hosted; the deployment ships the upstream license with it. The product itself does not load this script.
Material Design
Combra's interface follows the Material 3 design language. The implementation is our own: we wrote the components and the design tokens against Google's public guidelines at m3.material.io, and we do not ship any of Google's code. In particular, Google's material-web component library — which is published under the Apache License 2.0 — is not a dependency of Combra and none of it reaches your browser. Neither do Google's Material Symbols; our icons are Phosphor's, as listed above.
Following a published design specification is not redistribution, so there is nothing to license here. We note it because the resemblance is deliberate and we would rather say so. Material Design is Google's, we claim no rights in the name, and Combra is not affiliated with, endorsed by, or sponsored by Google.
Vendor logos
The Slack, Notion, GitHub, Google Drive, ChatGPT, Claude, and Obsidian marks appear in Combra to identify the services our integrations connect to. Those are trademarks of their respective owners, not open-source assets, and no license covers them. We use each mark nominatively — to name the vendor's own product, on the screen where you choose or configure that integration, in the vendor's current form and without implying any partnership or endorsement. Each owner retains all rights in its mark, and we will drop or update a mark at its owner's request.
What this page does not list
Combra's application code is compiled together with open-source libraries — React, Next.js, and their dependency trees — which do reach your browser as part of our bundle, under permissive licenses (predominantly MIT, Apache 2.0, and BSD). They are deliberately left off this page: several hundred transitive package names would bury the handful of components that carry an actual notice obligation, and none of them is redistributed as a recognizable third-party asset the way a typeface is. The complete manifest lives in the repository's lockfile; write to us if you need it.
Server-side components — the models, databases, and services that process your data — are not licensing questions but processing ones, and they are listed in our Sub-processors page.
