Privacy

This site collects close to nothing about you. Here is the whole of it.

There is no account, and nothing you have to sign up for

You can read every page on this site without giving us anything. There is no login, no gate in front of a clinic profile, and nothing you have to agree to before reading. The one thing you can choose to give us is your name and email address, for the weekly email below.

The weekly email

If you sign up for the weekly email, we keep your first name, your last name if you give it, your email address, the page you signed up on, and when you signed up. We also keep the words the signup box showed you, so we can show what you agreed to. We use all of this for one thing: sending you that weekly email.

It is stored in our own database. We do not sell it, rent it or share it with anyone, including the clinics listed here. We do not keep your internet address with it, and your name and email address are never sent to the tool that counts page views.

To stop the emails or have your details deleted, write to hello@longevityclinicshub.com and we will do it. Every email will carry an unsubscribe link once we start sending.

To keep automated sign-ups out, the signup box may use Cloudflare Turnstile, a check that runs in your browser only once you start filling in the form. Cloudflare sees your internet address when it runs, under Cloudflare's own privacy policy.

What happens to a ZIP code or city you type in

The city or ZIP box at the top of the homepage and the search on Find care ask for a city or ZIP code so they can send you to the right city guide. That matching happens in your own browser, against a list of the cities we cover that is already part of the page. Your ZIP code is not sent to us as part of finding your city. That is a narrower promise than it sounds, so read it next to what we count below: we never receive what you typed, and we do separately get a rough idea of where you are from your internet connection.

When the homepage box cannot match what you typed, it keeps a note of the place in your own browser's storage, and that note stays there. We are told that it failed to match a place, and we are not told the place. If you use the link it offers to email us about a city we are missing, then of course we have your email address, because you sent it, and the place you named is in the message you wrote.

The homepage quiz we used to run

Until 12 October 2026 the homepage had a short quiz that asked what was on your mind and where to look. It no longer appears on this site. When it ran, every answer was picked from a fixed list, with no free-text health question; we counted how many people picked each answer, in aggregate, and never joined an answer to a person, an email address, an enquiry form or an account. A link saved from it still opens a city guide with those answers in the page address, where you can see them.

If you type a five-digit ZIP code into the homepage box, the city guide opens with the clinics closest to you first. To do that, your ZIP code is kept in your own browser for the single hop from the homepage to the city guide, and the guide removes it as it reads it. It is not put in the address of the page and it is not sent to us or to anyone counting anything. The ZIP box on the city guide itself works the same way, in your browser only. If you type a city name instead, the list is not sorted by distance.

When the homepage box finds your city, or you pick one from the city menu in a homepage topic, your browser remembers which of our cities it was, so the topics can open that city's pages next time. It keeps the city's name from our own list, never the ZIP code or the words you typed, and what it remembers is not sent to us. Picking a city from a topic's menu is counted like any other click, as the name of the city you picked. Clearing your browser storage forgets it.

What we count

We count page views and clicks, so we know which cities and which pages are worth building next. That is the whole reason we count anything. It tells us that a hundred people read the Boston guide this week and four of them opened a clinic's own website. It does not tell us who any of them were.

The tool is called PostHog. It sets no cookies on this site, and it does not build a profile of you. We have turned off the parts of it that would: it does not record your screen, it does not replay your session, and it does not draw a heatmap of where you moved your mouse. It does not read what you type into a box.

That last sentence is the one we hold ourselves to hardest, so here is how. Every count this site records is picked from a fixed list written down in our code: the name of a city guide, the name of a clinic, which of four answers you chose, whether a search found a match or did not. Nothing you compose yourself is on that list. A check runs before every deploy that reads the code and fails it if a count carries anything you typed.

Your rough location comes along with the count. From your internet connection we get a country, a state and the nearest city. We use it to decide which cities to research next, and it is the most useful thing we learn all week: someone in Seattle reading the Boston guide is how we find out where to go.

It is rough, and worth knowing how rough. It is the city your connection appears to be in, which is often not the one you are standing in, and a phone or a work network or a VPN can put you in another state entirely. We do not keep the internet address it was worked out from.

If your browser sends a Do Not Track signal, we do not count you at all.

One more detail, because the promise above rests on it too. PostHog keeps a random anonymous number in your own browser's storage, so that reloading a page is not counted as two different people. It is not a cookie, it is not sent to any other site, and it is not attached to a name, an email address or anything you have told us. No profile is built from it on our side, and clearing your browser storage throws it away.

Cookies

We set no advertising cookies and run no advertising trackers. Nothing on this page is trying to follow you to another site.

What we do not do

• We do not sell or rent data about you to anyone, including the clinics listed here.
• We do not tell a clinic that you looked at its profile.
• We do not ask for health information, and you should not send us any.
• We do not build a profile of you, and nothing we count is tied to who you are.

That last point is worth being plain about given what this site is about. Which clinics a person reads about can reveal a great deal. So we keep the count and not the person: we know how many people opened a profile, and roughly which part of the country they were in, and nothing we hold says who any of them was.

Maps

The pages that list clinics for a test or a goal in a city can show those clinics on a Google map. The map loads only if you choose List + Map; until then nothing is sent to Google. When you open it, your browser fetches the map from Google, so Google receives your internet address and the part of the map you are looking at, under Google's own privacy policy. We send Google nothing about you, and we count only that the map was opened and which clinic's pin or card was clicked, by the clinic's name in our directory.

The map of cities on Find care is different: it is drawn into the page itself and fetches nothing from Google or anyone else. We count which city on it was clicked, and whether it was picked from a group of nearby cities.

Other websites can show our map of life expectancy by state on their own pages. When it appears on someone else’s site, it counts nothing: no page view and no click is sent to us.

Leaving this site

Clinic profiles link out to clinics' own websites and booking pages. Once you are there you are on their site under their privacy policy, not ours.
