Terms
of Service.

These terms (“Terms”) form a binding agreement between you and ISAAK LTD, a company registered in England & Wales under number 14504923, whose registered office is 9 Prince Of Wales Terrace, London W8 5PG, England (“ISAAK”, “we”). They apply when you access or use our website isaiak.com and the ISAAK Home Architect product (the “Service”).

By creating an account, joining the waitlist, or otherwise using the Service, you confirm that you have read these Terms and agree to be bound by them. If you do not agree, do not use the Service.

You may use the Service if all of the following apply:

• You are at least 18 years old, or the legal age of majority in your country of residence.
• You have the capacity to enter into a binding contract.
• You are not prohibited from using the Service under the law of the country you reside in or are connecting from.

The Service is designed for consumers in the United Kingdom. Availability in other countries is not guaranteed and may be restricted.

Some features require an account. You are responsible for keeping your credentials secure, for all activity under your account, and for notifying us without undue delay if you suspect unauthorised access. Sign-in links are single-use and time-limited.

You may close your account at any time by emailing support@isaiak.com. Deletion is processed within 30 days of request, subject to retention periods set out in our Privacy Policy for accounting and legal reasons.

The Service uses generative AI (image, chat, video). The following uses are strictly prohibited, in line with our payment processor's policies and applicable law:

Content restrictions

• Sexual or adult content of any kind, including AI-generated material.
• Content depicting minors in sexual, suggestive, or harmful contexts. Zero tolerance.
• Non-consensual imagery, deepfakes, impersonation of real people without their explicit consent.
• Hate speech, harassment, threats, or content inciting violence against any person or group.
• Self-harm, suicide, or graphic violence content.
• Illegal goods or services — drugs, weapons, fraud, money laundering, terrorism financing, sanctions evasion.
• Material infringing intellectual property: third-party floor plans, copyrighted artwork, trademarks, or any licensed material you do not have the right to use.
• Personal data of identifiable individuals (real addresses, identifying photos) without a lawful basis under data-protection law.

Use of the Service

• Use the Service to engineer, design, or plan anything illegal, unsafe, or prohibited under building or planning regulations in your jurisdiction.
• Attempt to reverse engineer, scrape, or copy the Service except as permitted by applicable law.
• Interfere with the operation of the Service, bypass rate limits, or attempt to extract other users' data.
• Resell or re-licence the Service, the credits, or the Output without our prior written consent.
• Use the Service in any country subject to comprehensive sanctions, or while you are on a sanctions list.

We may suspend or terminate accounts that breach these restrictions, refuse refunds in such cases, and report unlawful activity to competent authorities. Where the breach is serious, we may act without prior notice.

Your content

You retain all rights to the briefs, images, drawings, notes and other material you upload to the Service (“User Content”). You grant ISAAK a limited, worldwide, royalty-free licence to host, process, transmit, and display User Content solely to provide the Service to you. We do not use User Content to train our own or any third party's models unless you expressly opt in.

Generated output

We grant you a worldwide, perpetual, non-exclusive, royalty-free licence to use, reproduce, modify, and publish the drawings, reports, and other output generated for you by the Service (“Output”), for any lawful purpose. You are solely responsible for how you use the Output.

Our platform

Everything else that makes up the Service — the software, the website, the ISAAK name, logo, and brand — belongs to us or our licensors and is protected by intellectual-property laws. Nothing in these Terms grants you any right in our marks beyond referring to the Service fairly.

The Service uses artificial-intelligence models to generate drawings and analyses. Output is produced by pattern-matching and inference. It may contain mistakes, approximations, or statements that are out of date.

• Output is a starting point for a conversation with a qualified professional — an architect, chartered surveyor, structural engineer, solicitor, or planning consultant. It is not a substitute for professional advice.
• We do not warrant that Output is accurate, complete, code-compliant, buildable, or suitable for any particular purpose.
• You must not rely on the Service to make final decisions about structural alterations, party-wall matters, planning permission, building regulations, or anything that might affect health, safety, or the statutory rights of another person.

Some features are offered free of charge under a per-user trial allowance. Paid features are powered by prepaid credits: 1 USD buys 100 credits. Credit packs and per-action prices are listed on the Pricing page; per-action prices apply to the call you make at the time of generation.

Credits are not a subscription — nothing is auto-renewed and you are not enrolled in any recurring billing. You buy what you need and choose if and when to top up. Credits do not expire while your account is active and have no cash value outside the Service.

Local taxes (VAT, GST, sales tax) may be added at checkout based on your billing country, in line with applicable tax rules. Prices are quoted in USD; your bank applies its own conversion rate.

Refunds. Unused credits are refundable within 14 days of purchase (and longer where local consumer law requires). Used credits are non-refundable because the upstream AI provider has already been paid. Failed generations are never billed. The full refund process — including timelines, dispute handling, and access-revocation rules — is set out in our separate Refund & Disputes Policy, which forms part of these Terms.

The Service is under active development. We may add, modify, or remove features. Where a change materially reduces the functionality you have paid for, we will notify you in advance and, where appropriate, offer a pro-rata refund.

We may suspend or terminate your access to the Service if you breach these Terms, if your use creates a risk to us or another user, or if we are required to do so by law. Where possible we will give you advance notice and a chance to fix the issue. You may terminate by closing your account at any time.

On termination, your licence to use the Service ends. Clauses that by their nature should survive termination (intellectual property, disclaimers, liability, governing law) continue in force.

The Service is provided “as is” and “as available”. To the fullest extent permitted by law, we exclude all implied warranties — including of satisfactory quality, fitness for a particular purpose, and non-infringement — other than those that cannot be excluded under UK consumer law.

Nothing in these Terms excludes your statutory rights as a consumer. In particular, nothing limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other matter where liability cannot lawfully be limited.

Subject to the previous clause, ISAAK's total aggregate liability to you for any claim arising out of or in connection with the Service or these Terms, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the greater of (a) the fees you paid to us in the 12 months immediately preceding the event giving rise to the claim, or (b) £100.

We are not liable for indirect, special, or consequential loss, loss of profits, loss of business, loss of anticipated savings, or loss or corruption of data, to the extent that such exclusion is permitted by law.

You agree to indemnify and hold ISAAK harmless from any claim, loss, or cost arising from your breach of these Terms, your misuse of the Service, or your violation of any law or third-party right.

If something has gone wrong, please email support@isaiak.com first. We take complaints seriously and will work with you to resolve them. If we cannot reach a resolution, you may be entitled to use an alternative dispute-resolution scheme or the Online Dispute Resolution platform operated by the European Commission (for residents of EEA countries where applicable).

These Terms and any dispute or claim arising out of or in connection with them are governed by the laws of England & Wales. The courts of England & Wales have exclusive jurisdiction, except that if you are a consumer resident in another part of the UK or in the EEA, you may bring a claim in the courts of the country in which you reside, and mandatory local consumer-protection laws will apply.

• Entire agreement. These Terms, together with our Privacy Policy, are the whole agreement between us and you for the Service.
• Severability. If any clause is held unenforceable, the rest remains in force.
• No waiver. Our failure to enforce any provision is not a waiver of it.
• Assignment. You may not assign your rights under these Terms without our written consent. We may assign our rights to an affiliate or to a successor in a reorganisation or sale.
• Third-party rights. No one other than you and us has any rights under these Terms under the Contracts (Rights of Third Parties) Act 1999.
