NyayaTerms of sale
What you get when you buy Nyaya.
Last updated 16 October 2026.
What you are buying
A licence to install and use Nyaya. It is an annual licence, at the price shown in your currency, with tax added where it applies. You can pay for the year in full, in advance. That costs at least 15% less than 12 monthly instalments. Or you can pay in 12 monthly instalments, each invoiced in advance. If you pay in instalments, you owe the whole year once the licence starts. Stopping the instalments doesn't cancel what's owed. Your licence renews into the next year by default, paid the same way. You can turn renewal off in Nyaya's licence panel before the year ends. While card payments are off, renewal sends you an invoice. It never charges a card.
Our prices are set before tax. At checkout, Stripe Tax adds any VAT or sales tax due, worked out from your billing address. If you buy for a business and give its tax number, the reverse charge applies and no tax is added.
- One seat. One person, on one computer at a time.
- The seat moves. If you install on a new computer, the seat goes there. The old computer's dashboard has a button to take it back.
- For as long as you like. The licence does not expire. Your copy keeps working, at the version it is entitled to, whether or not you ever pay again, unless it has been changed in a way the licence doesn't allow.
Trying it first
You can use Nyaya free for fourteen days from the first time you use it, with nothing to pay and no card asked for. When the trial ends it stops until you buy.
Updates
Your licence includes every update while it is paid up. Each instalment you pay brings a month more of updates. A year paid in full brings twelve months. New versions arrive on their own. If an instalment is missed, or the year ends, your copy keeps working exactly as it does on the last day paid for, unless it has been changed in a way the licence doesn't allow. New versions stop arriving, security fixes included, and Nyaya shows a notice saying it is missing them. Reaching the dashboard from your phone stops too, because it runs for as long as updates do. When you pay what's owed, or for a new year, the updates start again. If you bought a licence once before, it keeps its twelve months of updates, and after that you move to an annual licence. We don't keep a card on file. We send your invoice and receipt.
What Nyaya does not do
- It does not give legal advice. Its reviews, redlines and lists of obligations are prepared by software for you to check. A qualified lawyer should review them before you rely on them, and you answer for what you sign and send.
- It never decides for you. Signing a contract, sending anything to the other side, accepting a change to a clause and deciding a legal risk are always yours.
- It does not send or sign anything. It prepares a redline for you. Giving it to anyone is your choice.
- It works only where its contract law has a rule pack. For now that is the UK. Where there is none, Nyaya sets nothing up.
It uses your own Claude subscription. Nyaya is a plugin for Claude Code and runs on the Claude plan you already have. That plan is not included in the price, and Claude's own terms and usage limits apply to it. Nyaya is not affiliated with Anthropic.
The data in your contracts
Nyaya keeps your contracts on your computer, and your own Claude reads what each agent's job needs. You decide what goes into Nyaya and you are responsible for the personal data in your contracts under the law that applies to you.
What you may not do
You may not copy, share, sell, rent, sublicense or otherwise redistribute Nyaya or any part of it, including the licence file inside your copy. You may not remove or work around the licence check. You may not reverse engineer, decompile or disassemble it, except to the extent that the law where you live allows this regardless of these terms.
You may change the instructions Nyaya's agents follow, for your own use of Nyaya. You may not change Nyaya, or any part of it, so that it does work another Polyglyph Analytica product does, or uses a feature, rule pack or capability your licence doesn't include. If a copy has been changed in this way, its check fails and it stops working, and we don't support it. Restoring the copy we supplied makes it work again. The licence check tells us whether your copy has been changed. It never sends what you changed.
Refunds
At checkout you agree to these terms. If you buy as a consumer, you keep your 14-day right to cancel, even after you've downloaded Nyaya.
You can get a full refund of a licence year within 30 days of its start. After that the year stands. The refund policy has the whole of it.
No warranty
Nyaya is provided as is. Polyglyph Analytica does not promise that its reviews find every problem, that a clause with no finding is lawful or enforceable, or that it is free of errors. Its checks follow the rule packs for your place, and a rule pack can be wrong or out of date. To the extent the law allows, Polyglyph Analytica is not liable for any loss arising from its use. Nothing in these terms takes away rights the law where you live gives you as a consumer.
Your data
Everything Nyaya works on stays on your computer. What leaves it, and why, is set out in the privacy policy.
Changes
The terms on this page on the day you buy are the ones that apply to your purchase. If they change, the date at the top changes with them, and a change never takes away a licence already bought.
