# IC OCR-A Licence

IC OCR-A is built in two layers, and they are licensed differently. This file
explains both in plain language.

## 1. The public-domain baseline

The outlines in IC OCR-A descend from John Sauter's OCR-A 1.0 release, published
via SourceForge and packaged by Debian as `fonts-ocr-a`. Both the SourceForge
project and the Debian copyright file declare that release to be in the public
domain. The glyph shapes themselves were specified by the American National
Standards Institute in ANSI X3.17-1977.

That baseline carries no restrictions from us. Nothing in this licence takes
away any right you already have in public-domain material. Full provenance,
including file checksums, is recorded in `UPSTREAM.md` in the project source.

## 2. This font software

Everything built on top of that baseline is the licensed part: the Width,
Weight, and Spacing axes, the generated masters, the corrected vertical
metrics, the contemporary spacing, and the compiled font files distributed
with this licence. That work is copyright Inke.

### What you may do

Buying a licence lets you:

- Install and use the fonts on machines you own or control.
- Use them to set text in anything you make, commercial or otherwise, including
  logos and product branding.
- Embed them in websites, applications, documents, videos, and games, provided
  the fonts are delivered as part of that product and not offered as fonts.
- Modify them for your own use, including subsetting and format conversion.
- Keep using any version you have licensed, indefinitely.

### What you may not do

- Redistribute, resell, sublicense, or give away the font files on their own.
- Publish them anywhere they can be downloaded as fonts, including public code
  repositories, asset libraries, and CDNs you do not control.
- Present them, modified or not, as your own typeface.
- Remove the licence, copyright, or vendor information embedded in the files.

If you want to use IC OCR-A somewhere this licence does not cover, ask. The
answer is usually yes.

## 3. No warranty

The fonts are provided as is, without warranty of any kind, express or implied.
To the extent permitted by law, the licensor is not liable for any claim,
damages, or other liability arising from the fonts or their use.

## 4. Not certified for OCR

IC OCR-A is a typeface inspired by and derived from OCR-A. It is **not**
certified for machine-readable optical character recognition, and it must not
be relied upon for cheques, payment advice forms, lockbox processing, or any
other application where scanner conformance matters. The ANSI and ISO standards
are not included and no conformance is claimed or implied.
