The agreement, in plain English

Terms of Service

Last updated: 1 August 2026
A note from us: this is a plain-English terms of service written to get Momentum started honestly and give you what you need to make an informed decision. It is not legal advice, and you should have a qualified solicitor review it before you rely on it. If anything here reads unclearly, tell us and we’ll fix it — that’s the whole spirit of the thing.

These terms are the agreement between you and Momentum, a habit-coaching service operated by Calvin Kudzai in the United Kingdom. By joining Momentum, you’re agreeing to them. We’ve written them to be readable rather than intimidating, because a relationship built on honesty shouldn’t start with fine print you can’t parse.

What Momentum is

Momentum is habit coaching. A real human coach designs a small number of habits with you, holds you accountable, and adjusts the plan as you go. It is not therapy, medical care, or mental-health treatment, and it’s not a substitute for advice from a doctor or a qualified professional. If you’re dealing with something that needs that kind of help, please speak to someone qualified — and we’ll gladly encourage you to.

Who can join

You need to be 18 or over and able to enter a contract.

Payment, renewals and the founding rate

Our refund promise

Your first month is fully refundable if Momentum isn’t working for you — no forms, no penalty, just email us. After that, we don’t offer refunds for partial periods, but you can cancel any time to stop future billing.

How the coaching works

Using Momentum fairly

Please use the service lawfully and don’t misuse it — no attempting to break, copy, or resell the platform, and no abusive behaviour toward your coach. We can suspend or end an account that does.

What belongs to whom

The Momentum brand, site, method and dashboard are ours. The data about your life — your habits, logs and notes — is yours, and you can export it if you leave.

No guaranteed outcomes

We’ll give you our honest best. But building habits depends on you turning up, so we can’t and don’t promise specific results. To the extent the law allows, Momentum is provided "as is", and our liability to you is limited to the amount you’ve paid us in the previous three months. Nothing in these terms limits liability that can’t legally be limited.

Ending things

You can cancel any time. We can end an account for a serious breach of these terms, and we’ll tell you why. If we ever stop offering Momentum, we’ll give you fair notice and a chance to export your data.

Your data

How we handle your information is set out in our Privacy Policy, which forms part of these terms.

The legal bits

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If we update them, we’ll post the new version here and, for anything significant, let you know. Questions? hello@mymomentum.coach.
