Open Source Licences

Effective date: 1 August 2026

1. Why this page exists

Nibit is built on open-source software. Many of those licences require us to reproduce their copyright notices and licence text in any product that distributes the code, and to tell you how to get the source. This page is how we do that.

Nothing here limits your rights under those licences. Where an open-source licence grants you something these Terms would restrict, the licence prevails - as stated in Terms section 12.

2. Where to find the notices

• This page lists the third-party components in nibit.ai, this website, and reproduces the full text of every licence they are distributed under.
• The desktop and mobile applications each carry their own manifest, generated from that build's dependency tree at build time rather than written by hand. It ships inside the installer so the attributions travel with the binary and stay readable offline, at Nibit.app/Contents/Resources/LICENSES.txt on macOS and %LOCALAPPDATA%\Programs\Nibit\resources\LICENSES.txt on Windows, and it is reachable in the app under Settings → About → Open source licences. The build writes the same manifest to both places, so the two cannot drift.
• Server-side components used to operate the Services are not distributed to you, so most licences do not require attribution for them. Where a licence does require it - a copyleft licence covering distributed code, for instance - the component appears below.

3. Components in this website

Generated from the dependency tree of nibit.ai at version 0.0.0.

Distributed to your browser. These are compiled into the JavaScript this site serves you, so their licences require the notices below.

Build toolchain. Nibit also uses open-source tooling that runs on our own machines to produce the site. None of it is distributed to you and none of it is compiled into what your browser receives, so those licences require no attribution here. Section 5 sets out the licence categories every dependency is checked against before it is added, build tooling included.

4. Typefaces

Typefaces are licensed separately from software and carry their own attribution terms.

The full text of the SIL Open Font Licence 1.1 is in section 9.

Satoshi. The Fontshare licence is a free commercial licence, not an open-source one, and its terms differ from the OFL - in particular around redistribution and bundling. Nibit loads Satoshi over the network from Fontshare's own CDN (api.fontshare.com), which is the use the licence is written for. Nibit does not self-host the font files, does not embed them in the desktop or mobile builds, and does not redistribute them. If a future build needs to embed the font for offline use, that requires a different licence from the Indian Type Foundry, and we will buy one before shipping it.

5. Licences we review before use

Some licences carry obligations that would change what Nibit can ship or how it must be distributed. Every new dependency is checked against these categories before it is added:

• Strong copyleft - GPL-2.0, GPL-3.0, AGPL-3.0. Linking these into a distributed application can require us to release our own source under the same terms, and AGPL can extend that to server-side use. Denied in anything Nibit distributes or runs as a service.
• Weak copyleft - LGPL, MPL-2.0, EPL. Allowed with review: usable when the component is unmodified and either dynamically linked or used only at build time. Modifying one of these means publishing the modifications.
• Source-available but not open source - BSL, SSPL, Elastic Licence, and "fair source" variants. These are commercial licences with restrictions. Business decision, not a technical one, and escalated rather than merged.
• Permissive - MIT, ISC, BSD-2-Clause, BSD-3-Clause, 0BSD, Apache-2.0, Unlicense, CC0. Allowed. Apache-2.0 additionally requires that we preserve its NOTICE file where one exists.
• No licence at all. Code without a licence is not free to use. An unlicensed dependency is a blocker, not a footnote.

The outcome, stated plainly: no strong-copyleft component ships in nibit.ai or in the Nibit desktop or mobile applications. The one weak-copyleft component anywhere in the tree is a build tool, and it is not distributed.

6. Getting the source

For any component distributed to you under a licence that entitles you to its source code, you can obtain it from the component's own public repository, linked in the generated manifest described in section 2.

No GPL- or LGPL-licensed component ships in nibit.ai or in the Nibit desktop or mobile builds, so there is no written-offer obligation to honour under GPL-2.0 § 3(b) or its equivalents, and this section is informational. If that ever changes, this page changes with it and the offer becomes real. In the meantime, if you want the corresponding source for any component in the version you received, write to legal@nibit.ai and we will point you at it.

7. Nibit's own code

Nibit's applications are proprietary. This page is an attribution notice for third-party components; it does not make Nibit's own source available and does not grant you a licence to Nibit's code. See Terms section 12.

8. Corrections

If you believe a component is missing from this page, misattributed, or listed under the wrong licence, tell us at legal@nibit.ai and we will correct it. Attribution mistakes are ours to fix, and we would rather hear about them than not.

9. Licence texts

SIL Open Font Licence 1.1

Applies to Newsreader (© Production Type) and Geist Mono (© Vercel, Inc.), as listed in section 4.

``` PREAMBLE

The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.

The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

DEFINITIONS

"Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.

"Reserved Font Name" refers to any names specified as such after the copyright statement(s).

"Original Version" refers to the collection of Font Software components as distributed by the Copyright Holder(s).

"Modified Version" refers to any derivative made by adding to, deleting, or substituting -- in part or in whole -- any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.

"Author" refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.

PERMISSION & CONDITIONS

Permission is hereby granted, free of charge, to any person obtaining a copy of the Font Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and unmodified copies of the Font Software, subject to the following conditions:

1) Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself.

2) Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold with any software, provided that each copy contains the above copyright notice and this license. These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission.

5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.

TERMINATION

This license becomes null and void if any of the above conditions are not met.

DISCLAIMER

THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM OTHER DEALINGS IN THE FONT SOFTWARE. ```

Only the licences above are reproduced, because they are the ones covering components distributed to you. The build tooling described in section 3 is not distributed, so its notices are not required here.

10. Changes

This notice is regenerated when the dependency tree changes, so it is updated more often than the other legal documents and without individual notice.

Each published version has a permanent, dated URL - for example, /legal/open-source/2026-08-01.
