Terms of service

Last updated: 19 October 2026

In short: use KT8 Tools on websites and domains you own or look after, don't use them to attack or spam anyone, and cancel whenever you like. These terms cover KT8 Tools and the paid plans and credits on kt8.com/tools/pricing/. KT8 Mail, KT8 Blog Builder and Installs.dev are free software you install in your own Cloudflare account and are covered by their own licences.

1. Who we are

kt8.com is run from the United Kingdom by paulobrien.com (“KT8”, “we”, “us”). You can reach us at hello@kt8.com or through our contact page.

2. Your account

You sign in with your email address and a single-use code. Keep access to that inbox safe, because anyone who can read it can sign in as you.
Give us your real name and a working email address. One free trial per person.
You must be 18 or over to buy a plan or credits.
You can delete your account at any time from your account page.

3. Fair use

Only test websites, domains and email addresses that you own or have permission to test. You must not use KT8 Tools to:

overload, attack or probe anyone else’s systems;
send spam, phishing or malware, or hide where a link really goes (short links are checked and can be switched off);
break the law, or anyone else’s rights;
get round the limits on your plan, trial or credits, for example with several accounts.

If you do, we can suspend or close your account. We'll tell you why unless the law or a safety reason stops us. You can report misuse on our abuse page.

4. Free trials

A free trial lasts 14 days and includes a set number of runs of each tool. No card is needed. When the trial ends the tools lock until you choose a plan or buy credits. Trials start straight away once you've confirmed your email address. We can end a trial that breaks these terms, and we limit how many new trials start each day.

5. Plans, credits and payment

Prices are shown in pounds on the pricing page and are what you pay. For now, plans and credits are for customers in the UK.
Plans renew automatically each month or year until you cancel. You can cancel at any time from your account, and your plan carries on to the end of the period you’ve paid for.
Credits last 12 months from the day you buy them and can be used on any tool.
Payments are taken by our payment partner, named on the checkout page. We never see or store your card details.
If we change a plan’s price, we’ll email you at least 30 days before it applies to you, and you can cancel before then.

Refunds are covered by our refund policy.

6. How the tools work

We work hard to keep KT8 Tools accurate and running, but test results are a guide, not a guarantee, and the tools may sometimes be unavailable while we fix or improve them. You can see live service status on our status page. We may change or retire a tool; if we retire one you’ve paid for, we’ll refund the unused part of your plan or credits.

7. Our liability

Nothing in these terms limits your rights as a consumer under UK law, or our liability for death or personal injury caused by our negligence, or for fraud. Otherwise, we aren’t liable for losses that weren’t foreseeable, or for business losses such as lost profit or lost data, and our total liability to you is limited to what you paid us in the 12 months before the claim.

8. Your data

Our privacy policy explains what we keep and why. We never sell or share your data unless the law requires it.

9. Changes and the law

We may update these terms. If a change matters to you, we’ll email you before it applies. These terms are governed by the law of England and Wales, and you can bring a claim in the courts of the part of the UK where you live.
