Version: 2026-09-30
Licensor: PAR2LABS PVT LTD, India ("we", "us")
Licensee: the person or organisation that downloads, installs or uses
the Software ("you")
Copyright © 2025–2026 PAR2LABS PVT LTD. All rights reserved.
The Tessera Viz Free Edition is free to use, including for commercial
purposes, under the terms below. It is not open source: its source code
is not published, and you receive only the rights this licence grants.
1. WHAT THIS LICENCE COVERS
1.1 The "Software" means the Tessera Viz Free Edition: the packages
named "@tesserify/..." that we make available free of charge, with
their type declarations, documentation and updates we give you.
1.2 This licence does not cover the paid packages (named
"@tesserify-pro/..."). They need a paid licence from us, or an
evaluation under the Tessera Viz Evaluation Licence Agreement.
1.3 "Your Application" means software, a website or a service that you
build, that uses the Software, and that adds substantial features
of its own.
2. WHAT YOU MAY DO
2.1 We grant you a free, non-exclusive, worldwide, non-transferable
licence, for as long as you comply with this licence, to:
a. install and use the Software to develop, test and run Your
Applications, for any purpose, including commercial purposes;
b. let your employees and contractors do the same for you, if they
are bound by terms at least as strict as these;
c. make Your Application available to its end users:
- as a website, web application or hosted service;
- inside your own organisation; or
- by giving or selling copies of Your Application to end users
in executable or minified form, provided the Software is built
into Your Application and end users cannot use it on its own;
d. make copies of the Software as reasonably needed for 2.1 a–c,
including backups.
2.2 There is no limit on the number of developers, applications or end
users. No licence key is needed.
3. WHAT NEEDS AN OEM LICENCE
You need a separate OEM licence from us to sell, license or distribute
to other businesses a product that includes the Software and that
others install or build on, for example:
a. on-premise or self-hosted software that you license to other
organisations;
b. a software development kit, library, component, framework or
developer tool;
c. a platform that lets its users build their own charts, graphs,
dashboards or visualisations (for example a business-intelligence
or low-code tool);
d. a white-label product that others sell under their own name.
4. WHAT YOU MAY NOT DO
You may not:
a. sell, rent, lease, lend, sub-license, publish or redistribute the
Software on its own, or as a separately usable part of anything
else, except as 2.1 c allows;
b. upload the Software, or any part of it, to a public package
registry or a public code repository;
c. reverse engineer, decompile, deobfuscate or disassemble the
Software, or try to obtain its source code, except where
applicable law expressly allows it despite this restriction;
d. remove or change any copyright, licence or other notice in the
Software;
e. remove, change, bypass or disable any licence check or technical
protection, or use a paid feature without a paid or evaluation
licence for it;
f. use the Software, or anything learned from it, to build a
product that competes with Tessera Viz as a visualisation
library or toolkit;
g. use our names, logos or trademarks, except to state truthfully
that Your Application uses Tessera Viz;
h. use the Software against any law, including export-control and
sanctions laws.
5. THIRD-PARTY COMPONENTS AND SERVICES
5.1 The Software includes some third-party components. Each is covered
by its own licence, listed in the notices supplied with the
Software. Those licences apply to those components.
5.2 Some optional features contact third-party services that you
choose or configure. For example, the map-tiles package loads map
tiles from OpenStreetMap and the Leaflet library from a public
content delivery network unless you set your own sources. Your use
of those services is under their terms, not ours.
6. DATA
6.1 The Software does not send usage data, telemetry or personal data
to us.
6.2 You are responsible for the data Your Application processes,
including the personal data of your end users, and for complying
with the laws that apply to it.
7. OWNERSHIP AND FEEDBACK
We, and our licensors, own the Software and all intellectual property
in it. You get only the rights written in section 2. Feedback you
choose to give us may be used by us without any duty to you.
8. UPDATES AND SUPPORT
8.1 We have no duty to give you updates, fixes or support under this
licence.
8.2 We may publish a new version of this licence. It applies to
versions of the Software released with it. A version of the
Software you already have stays under the licence it came with.
9. NO WARRANTY
The Software is provided "as is", without any warranty, express or
implied, including fitness for a particular purpose, merchantability
and non-infringement, to the fullest extent the law allows.
10. LIMITATION OF LIABILITY
To the fullest extent the law allows, we are not liable for any
indirect, incidental, special or consequential loss, or for any loss of
data, profit or business, arising from the Software or this licence.
Our total liability under this licence is limited to 100 US dollars.
11. ENDING THIS LICENCE
11.1 This licence ends automatically if you break it. When it ends, you
must stop using the Software and delete every copy you control.
11.2 Copies of Your Application that you gave or sold to end users
under 2.1 c before this licence ended may continue to be used by
those end users.
11.3 Sections 4, 6.2, 7, 9, 10 and 12 continue after this licence ends.
12. LAW AND COURTS
This licence is governed by the laws of India. The courts of India have
exclusive jurisdiction.
13. THE WHOLE LICENCE
This is the whole licence for the Software. If you also hold a paid
licence or an evaluation licence from us, that licence governs the
packages it covers.
