Terms of Service

These Terms of Service ("Terms") apply when you use the QuantumStack website, platform and services, including any done-for-you work we deliver for you.

By creating an account, starting a free trial or buying a package, you agree to these Terms. If you use QuantumStack for a business, you confirm you can accept these Terms on its behalf.

• You must be at least 18, or the age of majority where you live, to use QuantumStack.
• Give us accurate details when you sign up and keep them up to date.
• Keep your login private. You're responsible for everything that happens in your account.
• Tell us straight away at hello@quantumstack.pro if you think someone else has accessed it.

Every plan starts with a 7-day free trial. You can cancel at any time during the trial and you won't be charged.

If you don't cancel, your plan starts when the trial ends and you're billed for the plan and billing period you chose.

• Plans are billed in advance, monthly or yearly. Yearly billing saves 2 months compared with paying monthly.
• Founding-member pricing stays locked for as long as your subscription remains active.
• Your plan covers the platform and the AI. Text messages, phone calls and email sends above your plan's allowance are billed at standard usage rates, which you can see in your dashboard.
• Your AI allowance refreshes through the day. The Scale plan includes three times as much.
• Prices don't include taxes. We add tax where the law requires it.

If we change plan prices, we'll tell you before the change applies to you, and it will take effect from your next billing period.

You can cancel anytime from your QuantumStack billing dashboard. There are no contracts on monthly plans.

When you cancel, your plan stays active until the end of the period you've paid for and then isn't renewed. We don't refund partly used billing periods unless the law requires it.

Offers that need a 12-month commitment, such as half-price setup when you commit to 12 months of Build + Grow, are billed for the full 12 months.

When you buy a done-for-you package, we build the site or app described in that package after a free call to understand your business.

We usually launch within 7 days of having what we need from you. If your done-for-you build isn't live within 7 days, your second month of Build + Grow is free.

You own everything we build for you.

Your websites, content, customer list and sales belong to you. You can export your contacts at any time.

You give us permission to host, copy and display your content only as needed to run QuantumStack for you. How we handle personal data is explained in our Privacy Policy.

You're responsible for having the rights to everything you upload, and for the products, services and claims on your sites.

Our AI builds pages, writes messages and answers your customers. Like any AI, it can get things wrong.

Check important content before you publish it. You're responsible for what your sites say and what your AI assistants tell your customers.

Don't use QuantumStack to:

• sell or promote anything illegal, or break the law where you or your customers are
• send emails, texts or calls to people who haven't agreed to hear from you, or ignore unsubscribe requests
• upload malware, or try to break, overload or get around the security of the platform
• copy content you don't have the rights to, or impersonate someone else
• break the rules of the payment providers you connect

We may remove content or suspend accounts that break these rules.

Payments are processed by Stripe, PayPal, Square and GoCardless under their own terms. When you sell to your customers, the sale is between you and them: you're responsible for your refunds, taxes and customer service.

Domains, email providers and other services you connect are also covered by their own terms.

We keep improving QuantumStack, so features may change. If we remove something important you're paying for, we'll tell you in advance.

We work to keep the platform available, but we can't promise it will never be interrupted.

We may suspend or close an account that seriously or repeatedly breaks these Terms, doesn't pay, or puts other people or the platform at risk. Where we can, we'll warn you first and give you a chance to export your data.

QuantumStack is provided "as is". As far as the law allows, we aren't responsible for indirect losses such as lost profits, revenue or data, and our total liability to you is limited to what you paid us in the 12 months before the claim.

Nothing in these Terms limits rights you have under consumer law that can't be excluded.

We may update these Terms from time to time. We'll tell you about important changes by email or in your dashboard before they take effect. If you keep using QuantumStack after that, the new Terms apply.

These Terms are governed by the laws of the country where QuantumStack is registered, unless the law where you live gives you the right to use your local courts and laws.

If you have questions about these Terms, email hello@quantumstack.pro.
