Terms of Service

Pivot helps you follow a rehabilitation programme after ACL reconstruction, before it, or for a torn ACL managed without surgery: the typical programme for the route you choose and the stage you and your physiotherapist say you are in, or the one your physiotherapist gave you, with demonstrations, timers, reminders and a record you can share with them.

It is a companion to your physiotherapist and surgeon, not a replacement for either, and not something to rely on alone. The app is designed this way. Your physiotherapist decides when you move to the next stage, and you tell Pivot when they have.

• It does not diagnose or assess symptoms. It shows the same page of warning signs, and who to contact for each, to everyone. It will not tell you what a symptom is, whether it is serious, or whether you should worry.
• It does not decide you are ready. It shows what physiotherapists usually look for beside the numbers you record, and does not judge them. Your clinician decides when you move on.
• It does not change your programme from your medical details. Your graft, anything else repaired, your measurements, your check-ins and your surgeon's instructions are kept as your record. They do not change the exercises; the notes on each exercise say what is usually advised, and you and your clinician decide what applies.
• It does not monitor you. Nobody reads what you record. Nobody is alerted if you have a symptom, miss a session, or stop using the app. If you need help, you must contact a person.
• It is not a medical device. Pivot is not intended to diagnose, prevent, monitor, predict, prognose or treat any disease or injury, and it is not intended to replace clinical judgement. It shows a generic published programme for the stage you choose, it does not interpret your symptoms or your measurements, and it does not decide when you progress. Your clinician does.

If your physiotherapist or surgeon has given you a different programme, different thresholds, or different restrictions, follow them and not this app. They have examined your knee; Pivot has not.

The app is built to lose that argument: you can hide any exercise your clinician has not asked for, and hidden exercises never return, or put your clinician's own programme in and Pivot will run it as entered.

The thresholds, exercises, doses and demonstrated ranges are drawn from the published consensus literature on ACL rehabilitation. They are a conventional programme, not a personalised prescription, and they cannot account for what your surgeon found, how your knee is actually behaving, or anything else about you that you have not told the app.

Every threshold and dose is recorded against the published source it came from. Write to us if you want that list.

You agree to:

• Stop if something is wrong and contact a clinician, rather than pushing through because the app showed you a session.
• Record honestly. The numbers are for you and your clinician. A number you did not measure means nothing, and the person it misleads is you.
• Not use Pivot as your only care. It assumes you have a clinician, and moving on is their decision. If you do not have one, the app says so plainly during setup.
• Not use it for something else. Pivot is for people aged 16 and over recovering from ACL reconstruction, waiting for it, or managing a torn ACL with rehabilitation instead. If you are under 18, use it with your surgeon's or physiotherapist's agreement; if you are still growing, follow their programme instead. It is not a protocol for other knee surgery, and not general fitness training.

Pivot is not an emergency service and cannot summon one.

If you have chest pain or breathlessness, a foot that is cold, pale or blue, sudden severe pain far worse than it should be, or you feel very unwell, call 999 or go to A&E. If you have calf pain, or a calf that is hot, hard or swollen, contact 111 now. In every case, tell them you have had recent knee surgery. For a temperature or a wound problem, contact your surgical team today. For anything else that feels wrong, contact your physiotherapist or surgeon — or 111 if you cannot reach either of them. The app's warning signs page lists these; it does not contact anyone for you.

Everything you record stays on your device. There is no account and no server. See the Privacy Policy. In short, we never receive your data, so we cannot lose it, sell it or hand it over.

You are responsible for your own device: if you lose it, delete the app, or erase your data, we cannot restore your recovery, because we never had a copy. Take an export from “Your data” if that matters to you.

Pivot is free to download, and the first 7 days of guided sessions are free. After that, guided sessions need a subscription: £9.99 a month or £59.99 a year (UK prices, including VAT). Everything else in the app stays free: the warning signs, check-ins, your progress and measurements, the plan, the explainers and a copy of your data.

• You subscribe through the App Store or Google Play. They take the payment and run the billing, under their own terms.
• A subscription renews automatically at the end of each month or year until you cancel it. Cancel at least 24 hours before the end of the period to avoid the next payment.
• You can cancel at any time in your App Store or Google Play account settings, or from “Manage or cancel” in the app. You keep access until the end of the period you have paid for. Deleting the app does not cancel a subscription.
• If the price changes, the store tells you before the new price applies, and you can cancel before then.
• Refunds are handled by Apple or Google under their terms, not by us. This does not affect your statutory rights.

We may update the app, including the exercises, thresholds and copy, to correct errors or reflect better evidence. A material change to the clinical content will be described in the app. We may stop distributing Pivot; if we do, the copy on your device keeps working, because it does not need us.

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.

That comes first because it is the part that matters in an app like this. If Pivot contributes to harming you and that is our fault, nothing below protects us, and none of it is written to.

Your rights as a consumer stand alongside it. Under the Consumer Rights Act 2015 Pivot must be of satisfactory quality, fit for purpose and as described; if it is not, you are entitled to a repair, a replacement or a refund. If Pivot damages your device or your other content because we failed to use reasonable care and skill, we will put that right or compensate you for it.

Subject to all of the above:

• Using the app against clinical advice. We are not responsible for loss that arises because you followed Pivot where your physiotherapist or surgeon had told you something different, because you recorded a measurement you did not take, or because you used the app for something it is not for. Clauses 3 and 5 are the terms this refers to.
• Business losses. Pivot is sold for personal use, so we exclude loss of profit, loss of business, business interruption and lost opportunity.
• Your recorded data. We cannot restore it, for the reason given in clause 7: no copy of it ever reaches us. An export you have taken yourself is the only backup that exists.
• Everything else. For any other loss, our total liability to you is limited to the amount you paid for the app.
• The App Store. Apple distributes Pivot, takes your payment and handles refunds. Those are Apple's responsibilities under Apple's terms, not ours.

We have not tried to exclude anything beyond that list. Where a liability is not dealt with here the law decides it, and a term that turned out to be unfair under the Consumer Rights Act would not bind you in any event.

These terms are governed by the law of England and Wales.
