Your individual answers stay on your device. The questions, the classification, the clinic matching and the summary all run inside your browser. We never receive your answers as a set, and there is no account, no login and nothing stored against your name. Close the tab and they're gone — so print or copy the result before you leave if you want to keep it.
One anonymous count is sent when you reach your result. It records which of the four approaches you were matched to, which neighborhood you picked, whether you're using insurance, and a few pattern markers. It's added to a running tally. It is not a record of you.
Specifically, that count carries:
Two people who answer identically are indistinguishable from one person answering twice. We can tell you how many Brooklyn backs classified one way versus another. We cannot tell you who they were, and neither can anyone who compels us.
Why we collect it at all: the entire point of this pilot is to find out which kinds of back problem are actually walking around this neighborhood, and whether the local supply of physical therapy matches. That question needs counts. It does not need you.
Separately, we count how far people get. Each screen of the assessment adds one to a counter for that screen — "someone reached the movement questions," and nothing else. These counts carry no classification, no symptoms and no answers of any kind. They exist so we can see where the assessment is confusing enough that people give up, and fix it. A screen is counted once per attempt, so going back and forth doesn't distort it.
If you go to book a consult, that page asks a few things before it will show you a scheduling link: a safety screen, whether you'll physically be in New York State, whether the case involves a work injury or a legal claim, an optional question about where you'd want to be seen later on, and whether you've read two notices about referrals and video visits.
None of those answers leave your browser. They are held in the tab while you're on the page and they are gone when you close it. We never receive them. As with the assessment, the only thing that goes to our server is one of a handful of counts — that someone opened the page, that someone was stopped by the safety screen, that someone was outside the area we cover, or that someone reached the scheduling link. Those counts carry nothing else at all, and they are never combined with anything from the assessment.
The scheduling page itself is not ours. It is run by Cal.com and opens in a separate tab, and the consult itself takes place on Google Meet. The scheduler is deliberately a plain link rather than something embedded in our page — an embedded scheduler would mean running their code on a page where you have just answered health questions, which is exactly what the rest of this policy exists to avoid. Whatever you enter once you're there — your name, your email, the address for a home visit — is collected by Cal.com and by us, and is covered by this policy and by theirs. Nothing you answered on our booking page is passed to them, and no referral information is sent with the click.
What we deliberately do not do: there is no Google Analytics on this site, no advertising pixel, and no tracking script — not on the assessment, not anywhere. Your classification is never sent to an advertising platform, because there is no advertising platform connected to this site to send it to. The counting described above is our own, runs on our own server, and stores nothing but numbers.
For completeness, there is one thing on this site loaded from another company: the typeface, which comes from Google Fonts. Like any request to any server, that one shows Google your IP address and which page you were on. It is not analytics and it collects nothing about your answers, but we'd rather name it than claim a clean sweep we haven't earned. We intend to serve the font from our own server and remove it.
The "bring this to your PT" summary is generated on your device too. Printing or copying it puts it under your control; what happens to it after that is up to you.
The QR code on that summary. It's there so your physical therapist can tell us whether we got the classification right. It carries the classification and nothing else — no answers, no summary, nothing about you. And it carries it in the part of a web address that comes after a #, which browsers never send to a server. So when your PT scans it, our host records that someone opened the feedback page. It does not record what the classification was, and we could not reconstruct it if we tried.
We use what you provide to respond to you, to deliver the assessment or report you asked for, to improve the accuracy of the classification, and to understand which parts of the site are working. We do not sell your information. We do not share it with the clinics shown in your assessment results — clinic matches are editorial and one-directional; no clinic is notified that you were matched to them.
One exception worth naming plainly, because it's us. The result screen also offers you a consult with Daniel Seidler — the physical therapist who built this tool — through Gowanus PT. That is a self-referral and we'd rather point at it than bury it. It sits outside the ranked list: Gowanus PT is not one of the 15 clinics, is not scored against them, and does not displace any of them. If you told us you'd rather use insurance, that block leads with the fact that Gowanus PT bills no insurance and is in no network, so you can dismiss it before reading a word of the pitch. Clicking it tells us only that someone clicked — not who, and not what you were classified as.
We do not sell your information, and we do not share it with advertisers.
We handle health information under HIPAA's standards for protected health information. In practice that means: it's kept confidential, access is limited to what's needed to provide your care, it isn't disclosed without your authorization except where the law requires it, and you have the right to see and request corrections to your own record.
That standard applies to the clinical records created when you become a patient — an evaluation, a treatment note, a plan of care.
It's worth being precise about what that does not cover, because the distinction protects you: the back pain assessment doesn't create a record at all. Your answers stay in your browser and we never receive them, so there is nothing about you for us to protect, disclose, or be compelled to hand over. A clinical record begins only when you book and complete an evaluation.
Clinical records are kept for at least six years, which is what New York requires for physical therapy records. For patients who were minors at the time of care, longer.
Contact form and waitlist submissions are kept for up to 24 months and then deleted, unless you've become a patient — in which case the clinical retention rule above applies instead. Ask us to delete yours sooner and we will, subject to those legal requirements.
The anonymous assessment counts have no retention limit because there is nothing in them to expire. They are counts.
You can ask what we hold about you, ask for a copy, ask us to correct it, or ask us to delete it — email info@gowanuspt.com. Legal retention requirements for clinical records may limit deletion.
This site and its assessments are intended for adults. We do not knowingly collect information from children under 13.
If this policy changes materially, we'll update the date at the top of this page.
