PAR2LABS PVT LTD

Terms and conditions

The public terms for Tessera Viz and the PAR2 Labs portal. This is the one public home of these documents: the portal, our emails and our documentation link here.

How acceptance works

Each person who signs in to the portal at https://npm.par2labs.com accepts the portal terms, and the licence terms that apply to their organisation, by ticking one box at the first sign-in. The portal asks again whenever a document changes. A document's version id is the first 12 hex digits of the SHA-256 of its file, so any change to the text gives a new version id. The portal keeps a record of which versions a person accepted and when. The version shown below is the version the portal asks people to accept today.
