# Handwriting Lottie Studio - Third-Party Font Notices

This tool includes single-line and converted font data used to generate handwriting-style Lottie JSON files in the browser. The generated animation documents created by users are not font software.

Do not sell the font data files by themselves. Keep this notice with redistributed copies of the tool or font data.

## CustomScript.svg

- File: `fonts-data/CustomScript.svg`
- Display name in tool: Custom Script
- Basis: Pinyon Script
- Source license: SIL Open Font License 1.1

`CustomScript.svg` is a converted/derived single-line SVG font data file used by this tool. It is distributed under the SIL Open Font License 1.1. The upstream font name is used only in this notice to identify the source; the converted file uses the internal family name `Custom-Script`, and the UI presents it as `Custom Script`.

## Vara-Style JSON Font Data

These JSON files are converted path data used by the browser-side Lottie generator.

| File | Tool display name | Source font | License | Upstream |
| --- | --- | --- | --- | --- |
| `fonts-data/PacificoSLO.json` | Pacific Script | Pacifico | SIL Open Font License 1.1 | https://github.com/google/fonts/tree/main/ofl/pacifico |
| `fonts-data/ParisScript.json` | Paris Script | Parisienne | SIL Open Font License 1.1 | https://github.com/google/fonts/tree/main/ofl/parisienne |
| `fonts-data/shadows-into-light.json` | Shadow Hand | Shadows Into Light | SIL Open Font License 1.1 | https://github.com/google/fonts/tree/main/ofl/shadowsintolight |
| `fonts-data/SatisfySL.json` | Smooth Script | Satisfy | Apache License 2.0 | https://github.com/google/fonts/tree/main/apache/satisfy |

The converted JSON font data is presented in the tool under non-upstream primary display names to avoid implying endorsement by upstream authors and to reduce Reserved Font Name risk for modified font data. Source font names are retained in this notice for attribution and provenance.
