1. Who we are
Inkwell is supplied by Stamp Social Ltd, a company registered in England and Wales (company number 17188757), with its registered office at 71-75 Shelton Street, Covent Garden, London WC2H 9JQ. We are registered with the Information Commissioner's Office under registration number ZC142084. In these terms, "we", "us" and "our" mean Stamp Social Ltd, and "you" and "your" mean the person who installs or uses Inkwell. You can reach us at inkwell@stamp.foundation.
2. Your agreement with us
These Terms of Use, together with the Licence Agreement, the Privacy Policy and the Refund and Returns Policy, form the agreement between you and us. By installing or using Inkwell, you accept these terms. If you do not accept them, please do not install or use the app.
3. Eligibility
You must be at least 18 years old and able to enter into a binding contract to buy or use Inkwell. Inkwell is sold to consumers in the United Kingdom. If you are buying on behalf of a business, your statutory consumer rights may not apply in the same way, and the warranty and liability sections below set out what we agree to instead.
4. What Inkwell is
Inkwell is a desktop application for Windows and macOS that helps you find, read, summarise, organise, edit and create documents from your own files, using an AI model that runs entirely on your own computer.
Inkwell can read the following file types: PDF, Word (.docx, .doc), Excel (.xlsx, .xls), PowerPoint (.pptx), OpenDocument (.odt, .ods, .odp), plain text (.txt), Markdown (.md), comma-separated values (.csv), rich text (.rtf), web pages (.html, .htm), saved emails (.eml) and Outlook messages (.msg).
Inkwell can create new files from scratch when you ask: Word documents (.docx), Excel spreadsheets (.xlsx), PowerPoint presentations (.pptx), PDFs and plain text. A newly created file is always saved as a brand-new file of its own; it never replaces or overwrites anything you already had.
Inkwell can edit Word (.docx), Excel (.xlsx), PowerPoint (.pptx), plain text (.txt) and Markdown (.md) files. When you ask for an edit, Inkwell proposes the change and shows it to you first. The change is only made after you confirm it, and it is made to a separate working copy. Your original file is never altered or overwritten. Direct editing of PDF files is planned for a later version; for now, Inkwell can offer to make an editable Word copy of a PDF and leave the PDF untouched.
5. Your licence to use Inkwell
When you buy Inkwell you receive a personal, non-transferable licence to install and use the app on up to two computers that you own or control. The full terms of that licence, including the install limit and how to move your licence between machines, are set out in the Licence Agreement. You are buying a licence to use the software, not ownership of the software itself.
6. Buying Inkwell
You can try Inkwell before you buy, free and with no purchase, through the interactive demo on our website. The demo is a faithful replica of the app, so you can decide whether Inkwell suits you before any payment.
Inkwell costs a one-off price of £99. There is no subscription and no recurring charge. Payment is taken at the time of purchase through our payment processor, Stripe. Once your payment is confirmed you receive a licence key by email, which unlocks the app. Buying Inkwell is buying a digital download, and your cancellation and refund rights are explained in the Refund and Returns Policy.
7. Updates
Your purchase includes free updates within version 1 of Inkwell, at no extra cost, for as long as we maintain that version. Updates may add features, improve performance or fix problems. A future major version may be offered as a separate paid upgrade; you are never obliged to take it, and version 1 will keep working on the licence you bought.
8. Your files and your content
Inkwell works on documents you choose to open with it. Those files, and anything Inkwell reads, writes or creates from them, stay on your computer. The app does not upload your files, send your documents to us or to any third party, or keep any copy of them off your machine. You keep all rights in your own files and content. How we handle the limited personal data we do collect at purchase is set out in the Privacy Policy.
9. Acceptable use
You agree to use Inkwell lawfully and not to:
- copy, redistribute, resell, sublicense or share the app or your licence key, except as the Licence Agreement allows;
- reverse engineer, decompile or attempt to extract the source code, except to the extent the law expressly permits;
- remove, alter or work around the licence check or the two-computer install limit;
- use the app to break the law, infringe someone else's rights, or process content you have no right to process.
10. Availability and the licence server
The AI features of Inkwell run on your computer and work offline. A small online service of ours is used only to validate your licence key when you activate it, to move your licence between computers, and to recover a lost key. We aim to keep that service available but we do not guarantee it is uninterrupted, and brief outages do not affect your right to use the app you have already activated.
11. Intellectual property
Inkwell, its name, its design and the underlying software are owned by us or our licensors and are protected by intellectual property law. Inkwell includes open-source components, used under their own licences. Nothing in these terms transfers ownership of the software to you.
12. Warranties and what AI output can and cannot do
We provide Inkwell with reasonable care and skill, and where you are a consumer you have statutory rights under the Consumer Rights Act 2015 that we do not exclude or limit. Beyond those statutory rights, and to the extent the law allows, the app is provided "as is".
Inkwell works by running an AI model on your computer. That model produces probabilistic output: it predicts a likely answer from your files and your request, rather than retrieving a single fixed correct result. Because of how this technology works, the output can be inaccurate, incomplete or out of date, and it can sometimes state something confidently that is wrong or that is not in your documents at all. This is sometimes called a "hallucination". It is a normal characteristic of AI assistants of this kind, and it is not, on its own, a fault in the software.
Because the output is probabilistic, you should always check anything important before you rely on or act on it, and verify it against the source document or another trusted source. Inkwell is a tool to help you work with your own files. It is not professional advice and is not a substitute for professional, legal, financial or medical advice. You are responsible for reviewing anything you choose to act on, and for any decision you make based on Inkwell's output.
To help you review before anything changes, Inkwell uses a propose-and-confirm flow: it shows you a proposed change first, applies it only after you confirm, and writes to a separate working copy, so your original files are never changed without your confirmation. None of this affects the statutory rights described in the first paragraph of this section, or the rights set out in our Refund and Returns Policy.
13. Our liability to you
We do not exclude or limit our liability where it would be unlawful to do so, including for death or personal injury caused by our negligence, for fraud, or for any statutory rights you have as a consumer that cannot be excluded.
Subject to that, and to the extent the law permits, we are not liable for loss that was not reasonably foreseeable, for loss of data that you could have avoided by keeping your own backups, or for business losses where you use Inkwell for the purposes of a trade or profession. Inkwell never deletes or overwrites your original files, and we strongly recommend you keep your own backups regardless.
14. Ending this agreement
You may stop using Inkwell and uninstall it at any time. We may end your licence if you seriously or repeatedly breach these terms, for example by sharing or tampering with your licence key. If we do, we will tell you why where we reasonably can.
15. Changes to these terms
We may update these terms from time to time, for example to reflect changes in the app or in the law. The "last updated" date at the top shows when they last changed. Changes do not reduce the rights you have under the law of England and Wales.
16. Governing law
These terms are governed by the law of England and Wales, and any dispute may be brought before the courts of England and Wales. If you live in another part of the United Kingdom, you may also bring a claim in the courts of that part, and the mandatory consumer-protection law of where you live still applies to you.
