Third-Party Notices

Last updated November 4, 2026

PropertyPartner self-hosts the third-party libraries and web fonts below (no CDN); each is served same-origin under /assets. The full text of every license is committed alongside the vendored files in the repository, and each license was verified against the vendored files and the project's upstream license.

# Third-Party Notices

PropertyPartner self-hosts (no CDN) the third-party libraries and web fonts listed below. Each is
vendored under `src/PropertyPartner.Api/wwwroot/` and served same-origin from `/assets/…`. The full
text of every license is committed verbatim next to the vendored bytes at the path in the **License
file** column — copied from each project's upstream release, never transcribed here. Licenses were
verified against the vendored files, the woff2 `name` tables, the npm registry metadata for the
pinned version, and each project's upstream `LICENSE`/`OFL` file at that version.

## OFL fonts — Reserved Font Names

The SIL Open Font License requires that the license and the copyright statement (including any
Reserved Font Name) accompany the fonts; both are committed at the License-file paths above.
Reserved Font Names, verified against each font's woff2 `name` table and its upstream OFL copyright
statement:

- **Inter** — no Reserved Font Name declared.
- **Instrument Sans** — no Reserved Font Name declared.
- **Geist Mono** — no Reserved Font Name declared.

## ApexCharts license (discrepancy — needs an owner decision)

Issue #209 assumed ApexCharts is MIT. At the vendored version it is **not**. As of **v7.3.0** the
project's `LICENSE` (committed verbatim at `src/PropertyPartner.Api/wwwroot/vendor/apexcharts-7.3.0/LICENSE`)
is a **proprietary dual-license**: a no-cost *Community* license for organizations under **US$2M**
annual revenue, and paid *Commercial* / *OEM* licenses otherwise. (Earlier v3/v4 ApexCharts releases
were MIT.) Corroborating evidence:

- **npm registry** records the version's license only as the non-SPDX string `"SEE LICENSE IN LICENSE"`.
- The **vendored `apexcharts.min.js`** banner states just `(c) 2018-2026 ApexCharts` — no license name.

ADR-0045 D5 makes ApexCharts the default on-page chart library, so this is a product-license
decision, not a notices-file detail. It is called out in the PR for the owner.

## Server-side libraries noted here

NuGet packages are restored at build time (Central Package Management, `Directory.Packages.props`) and are not vendored;
their licenses travel in each package. A server-side library is listed here when a feature depends on it for a file
format the platform reads from a third party.
