Terms of use

Last updated 1 September 2026.

Who you are agreeing with

SkillMirror is a trading name used by an individual based in the United Kingdom. It is not a registered company. These terms cover the SkillMirror phone app and the website at skillmirror.net. By using either, you agree to them. Free. There are no payments, no subscriptions and no advertising.

What the product is, and is not

SkillMirror gives you measured feedback on your own movement, computed on your own phone. It is practice information, not medical, physiotherapeutic, coaching or safety advice. The measurements describe angles and timing; they do not know your body, your injuries or your limits.

You move at your own judgement. Warm up, use a safe space, and stop when your body says stop. If you have a medical condition or an injury, ask a professional before practising. Physical activity carries risk, and you accept that risk when you choose to practise.

What is yours

Your recordings, your practice history and your encrypted backups are yours, on your device. We take no licence over your movement or your footage, because nothing you record is received by anyone.

When you bring a reference video into the app — one you recorded, or one you already have — you are responsible for having the right to use it. The app asks about that before it accepts a clip, and it refuses clips it cannot accept. Do not bring in footage of other people without their agreement, and do not bring in footage you do not have the rights to.

Using the product fairly

  • Use it for your own practice, or to help someone who has asked you to.
  • Do not use it to record or analyse anyone who has not agreed to it.
  • Do not try to break it, overload the website, or interfere with anyone else’s use of it.
  • Do not copy, resell or redistribute the app or the website’s content beyond what the law where you live allows.

The app stores

When you get the app from Apple’s App Store or Google Play, that store’s own terms apply alongside these. Apple and Google are not responsible for the app or for these terms; we are.

Web accounts

The website offers no accounts today. If it does in future, you will need to be at least 16 years old, to give a real email you control, and to keep your passphrase safe; deleting the account will remove it. A web account will always be optional and separate from practising in the app.

Availability and changes

The product is in development. We may change, add or remove features, and we may withdraw the website or the app. We do not promise that either will always be available or free of faults. Because the app keeps everything on your phone, changes to the service cannot take your practice data away from you.

Responsibility

The product is provided free of charge, as it is. To the extent the law where you live allows, we are not liable for loss or damage arising from your use of it, including injury from physical activity you chose to do, or loss of practice data you did not back up. Nothing in these terms limits or excludes liability that cannot be limited or excluded by law — including liability for death or personal injury caused by our negligence, or for fraud — and nothing in them takes away rights you have as a consumer under the law of the country where you live.

Governing law

These terms are governed by the law of the United Kingdom. If you live elsewhere, you keep the protection of the mandatory consumer laws of your own country, and you may bring a claim in your own courts where that law allows.

Contact

Questions about these terms: hello@skillmirror.net. Our Privacy policy explains what happens to data; our Support page explains how to get help.

Written in plain language by the people who built the product. A review by a qualified lawyer is planned before the app is submitted to the app stores, and this page will be updated if that review changes anything.
