Klaudius

Terms of Service

Last updated: 23 October 2026

These terms govern your use of klaudius.dev (the “website”) and your subscription to and use of Klaudius (the “product”). They are made up of the subscription terms and the general terms. By accessing the website or using the product, you agree to these terms. If you do not agree, do not use them.

Bought Klaudius on an earlier licence? It keeps the terms you bought it under: read them here.

Subscription terms

B1. Your licence

Subject to these terms, and while your subscription is active, we grant you a non-exclusive, non-transferable licence to use the Klaudius desktop app, and the pipeline that comes with it, for your own commercial or personal use, on up to two computers at a time. It is a right to use the software, not a sale of it. A subscription is for a single individual or a single entity. As between you and us, what you make with Klaudius is yours.

B2. Licence checks and the computer limit

The app checks your subscription with us regularly, so it needs an internet connection. If it can’t reach us, it keeps working for at least 3 days after its last successful check. You can move your subscription between computers in the app; if you need to do that more often than the app allows, email us.

B3. Billing, renewal and cancelling

Your subscription is billed in advance, monthly or annually, by our merchant of record, Lemon Squeezy, at the price shown at checkout plus any tax that applies. A monthly subscription’s first payment also includes a one-off setup fee, charged again if you start a new monthly subscription after an earlier one has ended; an annual subscription has none. Your subscription renews automatically at the end of each month or year, and Lemon Squeezy charges your payment method, until you cancel. You can cancel at any time, online, at klaudius.dev/billing. Cancel before your renewal date and you won’t be charged again; you keep access until the end of the month or year you have already paid for. You can also switch between monthly and annual there; the new plan’s price applies from your next renewal.

B4. Failed payments

If a renewal payment fails, Lemon Squeezy will try it again and email you. If it stays unpaid, Klaudius stops starting new runs, and your subscription is then cancelled.

B5. Updates

While your subscription is active, you receive the updates we publish to the app and the pipeline, delivered automatically. We may add, change or remove features. During a period you have paid for, we will not remove what Klaudius is for: finding businesses, building websites for them, and sending those websites to them.

B6. When your subscription ends

When your subscription ends for any reason, including a refund:

  • (a) Klaudius stops starting new runs (a run already under way finishes);
  • (b) your licence to use the app and the pipeline ends; and
  • (c) everything you made with Klaudius stays yours and keeps working: the websites it built, your database, your outreach accounts, and your conversations in the app, which still opens so you can read them and save a copy of your data.

Subscribe again with the same email address and new runs start again. After a refund, email us first.

B7. Restrictions

You must not:

  • (a) copy, decompile, reverse-engineer or modify the app or the pipeline, except as using Klaudius needs or the law allows;
  • (b) get round or interfere with the licence check or the computer limit;
  • (c) share your licence key, or resell, sublicense or redistribute Klaudius or access to it;
  • (d) use Klaudius, or anything taken from it, to build or train a competing product or an AI model; or
  • (e) use Klaudius’s name or logo to promote a product of your own.

Asking Klaudius, in the app, to change how it works is not modifying it. Doing any of (a) to (d) is a material breach: we may end your subscription and your licence at once, without a refund.

B8. Refunds

The first payment of your first Klaudius subscription, monthly or annual and including any setup fee, is covered by our 7-day money-back guarantee, described in our Refund Policy; it is once per customer. Otherwise, we don’t refund renewal payments or the unused part of an annual payment, except as B9 and section 7 of the general terms set out or at our discretion.

B9. Price changes

We may change the subscription price. A new price never applies before your next renewal, and we’ll email you 2 to 4 weeks before it does, so you can cancel first. If you’re charged a higher price at a renewal and didn’t mean to carry on, email us within 14 days and we’ll cancel your subscription and refund the part of the period you haven’t used.

The founding price is the exception: an annual subscription started at the founding price, by 23:59 UTC on 7 November 2026, renews at that price for as long as it stays on the annual plan. It doesn’t carry over to a new subscription.

General terms

1. Who we are

Klaudius is operated by Cloudbot Limited (“we”, “us”, “our”), a company registered in England and Wales (company number 12374211), with its registered office at 3rd Floor, 86-90 Paul Street, London EC2A 4NE.

2. Disclaimer of warranties

Except as these terms or the law provide otherwise, Klaudius is provided “as is”, without warranties of any kind, express or implied, including of merchantability, fitness for a particular purpose and non-infringement. We don’t promise that it will be error-free, uninterrupted or compatible with every third-party service, or that it will bring you any particular results.

3. Limitation of liability

Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law doesn’t let us limit. Otherwise, our liability under these terms is limited to the amount you paid for Klaudius in the 12 months before the claim, and we’re not liable for indirect, incidental, special, consequential or punitive damages.

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

4. Your responsibility and indemnity

You’re responsible for how you use Klaudius and what you publish or send with it, including following the laws on marketing, electronic communications, data protection and consumer protection that apply to you. As far as the law allows, you’ll indemnify us against any claims, losses or expenses arising from that use.

5. Termination

We may end your licence or subscription if you breach these terms: at once for a material breach under B7, and otherwise with notice. When it ends, you must stop using Klaudius and delete any copies you have.

6. Privacy, and the phone app’s relay

Your privacy is governed by our Privacy Policy.

Klaudius runs on your computer, and for the personal data you process with it, such as your clients’ details, you are the controller. When you use the Klaudius phone app, our relay stores the messages between your phone and your computer until one of them collects them, at most 7 days, and we pass on the previews in its notifications. Those can include names, contact details and messages of your clients and the people you contact. For that, and only that, we act as your processor under Article 28 of the UK and EU GDPR, and we:

  • (a) process it only on your instructions, which are to pass it between your phone and your computer, unless the law requires otherwise. Using the phone app gives those instructions;
  • (b) make sure everyone who can access it is bound to keep it confidential;
  • (c) keep it secure: it is end-to-end encrypted with a key that never reaches us, so we can’t read it, and each message is deleted once it’s collected, or after 7 days if it isn’t;
  • (d) use these sub-processors: Supabase, which hosts the relay in the United States, and Expo, which sends notifications through Apple’s or Google’s notification service. We’ll email you before we add or replace one, and you can object by unpairing your phone;
  • (e) help you, as far as we can without being able to read it, to answer people exercising their data protection rights and to deal with a personal data breach, which we’ll tell you about without undue delay;
  • (f) delete it when the pairing ends, whether you unpair, your licence ends, or neither your phone nor your computer connects for 30 days; and
  • (g) give you the information you need to show that we keep to this section, and contribute to reasonable audits of it, if you ask at hello@klaudius.dev.

7. Changes to terms

We may update these terms, and we’ll email active customers about material changes. For subscribers, a change takes effect at the start of your next billing period after we email you, unless the law requires otherwise; if it’s materially worse for you, you can cancel before then, and on an annual plan we’ll refund the part of the year you haven’t used. Otherwise, using Klaudius after a change means you accept it.

8. Sanctions and eligibility

By buying Klaudius you confirm that you are not located in, ordinarily resident in or operating from a country or region under comprehensive UK, EU or US sanctions, and that you are not on a UK, EU or US sanctions list. If you are, we may refuse or cancel the sale, with a refund where the law allows.

9. Assignment

We may transfer these terms to a successor that takes over the Klaudius business through a merger, acquisition or sale. Our obligations to you transfer with them on the same terms. You may not transfer your licence or subscription without our written consent.

10. Governing law

These terms are governed by the laws of England and Wales, and disputes go to the courts of England and Wales. If you’re a consumer, you keep the protection of the mandatory consumer law where you live, and can also bring a claim in the courts there.
