Terms of sale

What you are buying, and what you can do with it

Written to be read rather than to be survived. Last updated 26 July 2026.

The short version

You pay once and you own your copy for good. You can use it commercially inside your own business and change it however you like. You cannot resell it or pass it on to anyone outside your organisation. If you do not get on with it, ask for a refund within 60 days and you get your money back without having to explain yourself. Updates come by pulling from the repository, for as long as I keep publishing them.

Who you are buying from

Abaxar is made by Rich Vaughan, a sole trader in the United Kingdom, trading as The Rich Stack. The sale itself goes through Polar, which acts as the merchant of record. That means Polar is the seller on the transaction, handles the payment and any tax due on it, and issues the receipt, while the product, the licence and the support are mine.

Polar's own terms cover the payment. These terms cover the product and the licence. Where the two touch, such as a refund, the refund is processed by Polar and honoured by me on the terms below.

What you are buying

One payment for Abaxar, delivered as read-only access to a private repository. Abaxar runs on your own computer, against databases and API credentials that stay on your own computer. There is no account to keep paying for, no seat count, and no server of mine in the path between you and your data.

You are buying the thing as it exists on the day you buy it. The sales page and the videos describe what it does today, and I do not commit to building anything that is not already there. If a specific capability is the reason you are buying, ask me first and I will tell you plainly whether it exists.

The licence you get

On purchase you are granted a perpetual, worldwide, non-exclusive licence to Abaxar on the terms of the PolyForm Internal Use License 1.0.0, which ships in full as the LICENSE file in the repository you are given access to. That file is the licence. This paragraph is the grant of it.

In practice that means you can use Abaxar for any internal business purpose, including a business that makes money, and you can modify it as much as you like. Your organisation includes organisations under common control, so a group of brands you own is covered by one purchase rather than needing one each. What you cannot do is distribute it: no reselling it, no publishing it, no giving a copy to a client, and no running it as a service for someone else. The licence is not revocable at my whim, so once you have it, it is yours.

If you need to deploy it into somebody else's business, that is what the done-for-you engagement is for, and it includes a licence for that client.

Price and payment

The price is the one shown at checkout. The founding price applies to the first fifty buyers and rises after that, which is stated on the sales page rather than being a surprise. Payment is taken by Polar in pounds sterling. Any tax on the transaction is Polar's to handle as the seller of record.

Getting access, and what to do if it does not arrive

Access is granted by connecting a GitHub account to your Polar customer record after payment. That connection is a real step you have to take, and until you take it there is nothing for the access to be granted to. The page you land on after paying explains it.

If you have paid and cannot get in, email rich@therichstack.com and I will sort it by hand. Nobody who has paid stays locked out because an automated step misfired.

Refunds

Sixty days, no questions. If you want your money back within sixty days of buying, email rich@therichstack.com and ask. You do not have to give a reason, you do not have to prove you tried, and I will not argue with you about it. The refund is processed through Polar back to the way you paid.

When a refund goes through, your access to the repository ends and your licence ends with it, because you have not bought the thing any more. Anything you built on top of it is yours, and I have no way to reach into your machine and no interest in doing so, but continuing to run Abaxar after a refund is not something the licence covers.

This promise is more generous than the law requires and it does not replace your statutory rights. If you are buying as a consumer rather than for a business, you also have the usual right to cancel a digital purchase, and where the two differ you get whichever is better for you.

Updates and support

Updates are published as releases on the repository and you take them by running the update command, which tracks the newest release. I intend to keep publishing them and I have every reason to, but I am not promising a release schedule, and a one-time payment does not buy an obligation to develop forever. If I ever stop, you keep the copy you have and it carries on working, which is most of the point of it running locally.

Support is by issues on the repository, answered by me. There is no response-time guarantee, because it is one person and pretending otherwise would be a lie. In practice you will usually hear back within a working day.

What the software does not promise

Abaxar reports on data it reads from your own platform accounts using credentials you supply. The numbers it shows depend on what those platforms return, and the platforms change their APIs, restate their own historical figures and impose their own limits. Beyond the statutory rights you have as a buyer, it is provided as it is, without a warranty that it will be uninterrupted, or that every figure will reconcile with every other tool you own.

It is a reporting tool, not advice. Nothing it displays is accounting, tax or investment advice, and you should not file anything with anybody on the strength of a dashboard without checking it. Keeping your own API credentials safe, and following the terms of the platforms you connect, is yours.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be limited by law. Otherwise, and to the extent the law allows, my total liability to you is limited to what you paid.

Done-for-you engagements

The done-for-you service is a separate arrangement, invoiced directly rather than bought through checkout, and confirmed in writing before it starts. The fee includes an Abaxar licence for the business it is deployed into, so a client ends up holding their own licence rather than borrowing mine.

During an engagement I never take custody of your credentials. Where I need access I ask for a named account inside your own platform, granted by you, visible to you, and revoked by you at handover. Details are on the done-for-you page.

Ending the licence

The licence ends if you refund, and it ends if you breach it in a way you do not put right after I have asked. Ending it does not entitle me to anything of yours, and there is no clawback of the work you have done with it.

The legal bits

These terms and any dispute about them are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you are a consumer, protections in your own country that cannot be overridden by a clause like this one still apply to you.

If one part of these terms turns out to be unenforceable, the rest still stands. The version of these terms in force on the day you buy is the version that applies to your purchase, so a later change here does not reach backwards into a sale that already happened. The date at the top is how you tell.
