Terms of service

LongLifeList is a publisher and a directory. We grade published evidence for longevity interventions, list clinics and labs, and provide calculators. We are not a healthcare provider, we do not practise medicine, we do not employ the clinicians listed in the directory, and we do not sell treatment.

Everything on this site is general health information. It is not a diagnosis, a treatment plan or a prescription, and it cannot account for your history, your medicines or your test results. An evidence grade is a statement about a body of published research, not a statement about you.

• You need to be 18 or over to create an account. We do not knowingly hold data about children, and we do not profile or advertise to them.
• Keep your credentials to yourself, and turn on two-factor authentication if you are going to store health data.
• One person per account. Sharing an account with health data in it means sharing your health data.
• You can delete your account at any time from your settings. Health data is deleted with it, on the schedule in the health data notice.

Read it, quote it, teach with it, link to it. Our evidence grades and the tables behind them are published under an open licence with a citation requirement — the terms are on the data and API page.

You keep ownership of what you write. You give us a licence to publish it here and in our apps. Reviews must be your own experience of a service you actually received, and they are held to the review guidelines.

Do not put medical details about yourself in a public review or an enquiry form. Those are not secure clinical channels and they are not stored as health records.

• Subscriptions renew automatically until you cancel, and you can cancel at any time from your settings. Cancelling stops the next renewal; it does not refund the period you are in.
• Prices are shown in your own currency including applicable tax before you pay.
• If we materially reduce what a paid plan includes, we tell subscribers before it happens and you can cancel for a pro-rata refund.
• Where local law gives you a cooling-off period — 14 days in the EU and UK for distance contracts — it applies, and using the service during it does not waive it unless you expressly agree.

• A listing is not an endorsement. An LLL Verified badge means we checked a specific list of things on a specific date, and the badge says which date.
• Prices, services and opening hours come from the clinic or from public sources. They go out of date. Confirm before you travel.
• We are not a party to anything you agree with a clinic. Your care, your bill and your recourse are between you and them.
• Paid placements are labelled and are returned in a separate block from organic results. Money cannot buy organic position — the mechanism is described on our how-we-make-money page.

We work hard to be accurate and we publish our corrections. We do not warrant that the site is error-free or that any particular intervention will work for you. To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability is limited to what you have paid us in the previous twelve months.

Nothing here limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be limited under the law that applies to you. In the EU and UK, your statutory consumer rights are unaffected by anything in these terms.

We will give at least 30 days’ notice by email before a change that materially reduces your rights, and we keep the previous version available. For a dispute, write to hello@longlifelist.com first — most things are a misunderstanding and get fixed in a week.

If that does not work, you keep every route the law gives you, including your local courts and any consumer dispute scheme available where you live. We do not ask you to waive a class action or to arbitrate, because a term you would only discover when you needed it is not a term we want.
