What you get when you buy Kylakas.

Last updated 16 October 2026.

What you are buying

A licence to install and use Kylakas. It is an annual licence, at the price shown in your currency. 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. 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. We send your invoice and receipt. Your licence renews into the next year by default, paid the same way. You can turn renewal off in Kylakas's licence panel before the year ends. While card payments are off, renewal sends you an invoice. It never charges a card.

• 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 Kylakas 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 Kylakas 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.

Employee seats

An employer can buy Kylakas seats for their staff, on an annual licence like any other. The employer holds the seats. They give each one to a member of staff by email address, from their seats page, and they move a seat when someone leaves. Each person given a seat gets a licence of their own, for their own computer. Its updates run while the employer's seats are paid up. Renewal of the seats is the employer's to turn off. A person on a seat has no payment of their own, so their copy offers no buying, renewal or refund. If the employer moves a seat on, that person's copy gets no more updates. Their copy keeps working on the version it has, unless it has been changed in a way the licence doesn't allow.

What Kylakas does not do

• It never acts. It never moves money, opens an account, places a trade or contacts a provider.
• It never advises. It is not financial, investment, tax or legal advice, and it is not regulated by the Financial Conduct Authority.
• It never decides for you. What you do with its sums is up to you.

It uses your own Claude subscription. Kylakas 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. Kylakas is not affiliated with Anthropic.

What you may not do

You may not copy, share, sell, rent, sublicense or otherwise redistribute Kylakas 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 Kylakas's agents follow, for your own use of Kylakas. You may not change Kylakas, 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 Kylakas.

You can get a full refund of a licence year within 30 days of its start. After that the year stands. We refund to your payment method. The refund policy has the whole of it.

No warranty

Kylakas is provided as is. Polyglyph Analytica does not promise that any projection will come true, that its sums suit your circumstances, or that it is free of errors. Projections rest on assumptions about decades to come, and all of them will be wrong to some degree. 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 Kylakas 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.
