Terms of Service and End User Licence Agreement

Last updated 27 September 2026. Version restwren-terms-2026-09-27.

1. Who we are

Restwren is supplied by Nikah AI Ltd (NIKAH AI LTD, company number 17199968, registered in England and Wales, registered office Office 1216, 60 Tottenham Court Road, London W1T 2EW), trading as Restwren and referred to as "we", "us" or "our". You can contact us at support@restwren.com. These terms apply to the Restwren editor extension, the restwren command-line tool, licence keys and this website.

2. Your licence

Free tier. We grant you a free, non-exclusive, non-transferable, worldwide licence to install and use the free features of Restwren for any lawful purpose, including commercial work, on any number of computers.

Pro subscription. While your subscription is active and paid, we grant you a non-exclusive, non-transferable licence for one named person to use the Pro features on any computers that person uses. A Dev Classics bundle key gives the same right in each product it names. Your licence key is personal: do not share it, publish it or commit it to a public repository. If you use the CLI in continuous integration, store the key as a masked secret.

You must not remove or work around the licence check, share or resell keys, redistribute the Pro features, or copy, decompile or reverse engineer the software except to the extent the law allows you to (for example, under sections 50B and 296A of the Copyright, Designs and Patents Act 1988).

The software includes open-source components that are licensed to you under their own licences, listed in the third-party notices. We keep all other rights in the software.

3. Subscriptions, prices and automatic renewal

• Pro costs £2.99 a month or £29 a year. The Dev Classics bundle, when offered, costs £5.99 a month or £59 a year. Prices are in pounds sterling and the price shown is the total you pay.
• You pay in advance for each month or year. Your subscription renews automatically at the end of each period, and the same amount is taken with the payment method you gave, until you cancel.
• For annual subscriptions, Stripe sends a reminder email before each renewal.
• We will not raise the price of your subscription without telling you by email at least 30 days before the change applies to you. You can cancel before then if you do not accept it.
• Payment is taken by Stripe. Where Stripe's Managed Payments service handles the sale, Stripe's reseller (Link, known in the UK as Onelink) acts as merchant of record for the payment and you also accept its terms at checkout. The licence to use Restwren is always granted by us under these terms.
• Licence keys expire shortly after the end of each paid period and the extension renews them automatically while your subscription is active. If a renewal payment fails, Pro keeps working for up to 7 days while Stripe retries the payment.

4. Cancelling

You can cancel at any time in the Stripe customer portal, reached from Manage subscription, or by emailing us. Cancelling stops future payments; Pro keeps working until the end of the period you have already paid for, then Restwren returns to the free tier. Your files are not affected.

5. Your 14-day cancellation right for digital content

If you are a consumer, you normally have 14 days to cancel a contract made online. For digital content that is supplied immediately, that right ends once supply starts if you expressly asked for immediate supply and acknowledged that you would lose the right (regulation 37 of the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013). Before you pay, our checkout asks you to confirm both, and we record the time you did so with your order. Your licence key is issued as soon as payment is confirmed, so the 14-day right to cancel the purchase ends at that point. This does not affect your right to cancel future renewals or your rights if the software is faulty (see section 7). Full details are in the refund and cancellation policy.

6. Using the software

Restwren sends the requests you write to the servers you choose. You are responsible for having permission to call those APIs and for the data you send to them. Requests do not pass through us. The privacy notice explains what we do and do not process.

7. Your legal rights and our liability

If you are a consumer, you have legal rights under the Consumer Rights Act 2015: digital content must be of satisfactory quality, fit for purpose and as described. If it is not, you are entitled to a repair or replacement and, if that is not possible or does not fix the problem, to some or all of your money back. If faulty digital content we supply damages your device or other digital content and that damage would not have happened had we used reasonable care and skill, we will repair the damage or pay you compensation. Nothing in these terms affects these rights. Citizens Advice can tell you more.

Apart from those rights and any others that cannot be excluded by law, the software is provided "as is". We do not promise that it will be free of errors or that it will work with every API or editor.

If you use Restwren for business, we are not liable for loss of profit, revenue, business, goodwill or data, or for any indirect or consequential loss, and our total liability to you in any 12 months is limited to the amount you paid us in that period.

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be limited or excluded by law, including under the Consumer Rights Act 2015.

8. Changes and ending the licence

We may update the software and these terms. If a change to these terms materially affects a paid subscription, we will tell you before it applies and you may cancel. We may end your Pro licence if you seriously break these terms (for example by sharing or reselling keys); if we do so without good reason we will refund any unused part of your subscription.

9. Law and disputes

These terms are governed by the law of England and Wales. If you are a consumer, you may bring proceedings in England and Wales, or in Scotland or Northern Ireland if you live there. Please contact us first at support@restwren.com so we can try to put things right.
