Open Source Notices
This platform is built from work other people released under open licenses. Each one is listed here with the license it is used under, and the full text of every license ships with the source.
Signature Faces
The script faces a signer can type a signature in. These are embedded in the signed PDF itself, which is what their licenses permit and what makes the document readable anywhere.

Apache License 2.0
A script face a signer can type their signature in. It is the one face here under the Apache license rather than the Open Font License, so its notice is reproduced in full.

Optional Server Tools
Neither of these is bundled. An operator running their own server may install them, and the product uses them when they are present. Each one runs as a separate program, invoked on its own command line.

Anything missing from this page is an oversight rather than a claim. Tell the operator of this installation and it will be added.
The privacy notice for signers covers what is recorded about a person, which is a different question from the one this page answers.
