Terms of use

Last updated 19 August 2026. Swell is in early access, and these terms will change as the product does.

These terms are the agreement between you and Swell when you use the app or this website. By creating an account you accept them. If you do not accept them, please do not use Swell.

Swell is not medical advice

Swell is not financial advice

Plans are AI-generated

Where Swell generates a plan, it does so using a third-party AI model, based on the data you have logged.

• Plans may be inaccurate, incomplete, or simply wrong. AI systems produce plausible-sounding output that can still be false.
• Plans are general suggestions produced from your own numbers. They are not personalised professional advice of any kind, medical or financial.
• You are responsible for your own decisions. Read anything a plan suggests with judgement, and check anything that matters with a qualified professional before acting on it.
• Generating a plan sends your log data to our AI provider, and some plans are generated automatically rather than on request. That is explained in the privacy policy, which is worth reading.

Your account

• You need an account to use Swell, and the details you give us must be accurate.
• Minimum age: TODO — not yet set. This section will state the minimum age once that decision is made.
• Your account is yours. Keep your login details to yourself, and tell us at hello@swellapp.co.uk if you think someone else has access to it.
• You are responsible for what happens under your account.
• You can delete your account at any time from within the app. What that removes is set out in the privacy policy.

Acceptable use

Use Swell for its intended purpose — tracking your own life. Do not:

• break the law, or use Swell to help anyone else do so;
• try to access another person's account or data;
• attack, overload, probe or reverse engineer the service, or try to get around its security or rate limits;
• scrape or bulk-extract data by automated means;
• resell, sublicense or repackage Swell as your own service;
• upload anything unlawful, or anyone else's personal data that you have no right to hold.

We can suspend or close an account that breaks these rules. Where it is reasonable to do so we will tell you why first.

Free during early access

Swell is free while it is in early access. There is no subscription, no paid tier, and we take no payment from you at present.

That may change in future. If we introduce charges, we will give you notice by email before anything becomes payable, and you will never be charged without agreeing first. Nothing here obliges you to pay for anything you have already used for free.

Service availability

Swell is early access software, offered as it is.

• We do not guarantee any level of uptime, and we give no service level agreement.
• The service can be unavailable, interrupted, slow, or affected by problems at our hosting or infrastructure providers.
• We can change, suspend, or withdraw features — including plan generation — at any time, and the product will change substantially while it is in early access.
• If we decide to discontinue Swell altogether, we will give you reasonable notice and a way to export your data first.
• Keep your own copy of anything you cannot afford to lose. We take care with your data, but no service is immune to loss.

Your data

How we handle your personal data — including health data, and the log data sent to our AI provider — is set out in the privacy policy, which forms part of these terms. The data you log stays yours; we make no claim of ownership over it.

Our content

The Swell name, branding, interface and underlying software belong to us. Using Swell does not transfer any of that to you. You may use the service, and that is the extent of the licence granted.

Limitation of liability

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited or excluded. Your statutory rights as a consumer are not affected.

Subject to that:

• Swell is provided as it is and as available, without warranties beyond those that cannot be excluded by law. We do not warrant that it will be uninterrupted, error-free, or that anything it produces will be accurate.
• We are not liable for loss or damage that was not reasonably foreseeable, for loss of profit, revenue, business or opportunity, or for loss or corruption of data beyond what we could reasonably have prevented.
• We are not liable for decisions you make on the basis of the service or a generated plan, including decisions about your health, your training, your diet or your money.
• Because Swell is currently supplied free of charge, our total liability to you for any claim connected with the service is limited to TODO — legal review.

Swell is for personal use. We are not liable to you for any business losses.

Changes to these terms

We will update these terms as the product changes. The date at the top always shows the current version. If a change materially affects your rights, we will tell you by email rather than relying on you to notice.

Continuing to use Swell after a change means you accept the updated terms. If you do not accept them, you can delete your account.

Ending this agreement

You can stop using Swell and delete your account whenever you like. We can suspend or end your access if you break these terms, or if we discontinue the service. Deleting your account ends this agreement, apart from the parts that by their nature survive it, such as the limitation of liability.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute arising from them. If you live elsewhere in the UK, you may bring proceedings in your local courts where the law gives you that right.
