TrainerLens

Terms of use

Last updated 12 November 2026

The short version

  • Membership is US$29.99 a month or US$299 a year. Your card is charged the day you join and then automatically every month, or every year, until you cancel.
  • You can cancel at any time, in under a minute, on the membership page. No more payments are taken and you keep your membership to the end of the time you paid for.
  • Your trainer is artificial intelligence, not a person. It can be wrong. It is not medical advice.
  • Exercise can injure you. You train at your own risk and you accept that risk.

Who we are

TrainerLens is run by LeoTech Services LLC, a company in Florida, United States ("we", "us"). These terms are the agreement between you and us for using TrainerLens and its AI trainer. By joining or using TrainerLens, you agree to them and to the privacy policy. If you do not agree, do not use TrainerLens. You can reach us through the contact page.

Membership, price and automatic renewal

TrainerLens is a paid membership. There is no free version.

You choose how to pay when you join:

  • Monthly: US$29.99 a month. We charge your card on the day you join, and then automatically on the same date each month, until you cancel.
  • Yearly: US$299 a year. We charge your card on the day you join, and then automatically on the same date each year, until you cancel.

Your membership renews by itself. You do not need to do anything to keep it, and you will keep being charged until you cancel. If your bank changes the payment into another currency it may add its own fee.

Your membership starts as soon as your first payment goes through, and we email you a confirmation with these terms and how to cancel.

If we ever change the price, we will email you at least 30 days before the change, and you can cancel before it applies.

If a payment fails, we tell you by email and try again over the next few days. If it still cannot be taken, your membership pauses until you update your card.

Cancelling

You can cancel at any time on the membership page at trainerlens.com/membership. Confirm your email, press "Cancel membership", and it is done. We email you a confirmation.

When you cancel, no more payments are taken. You keep your membership until the end of the month or year you have already paid for, and you can change your mind any time before then. We do not refund part of a month or part of a year, except where the next section or the law says otherwise.

If you live in the United Kingdom: your 14 days

You have the right to cancel within 14 days of joining, without giving a reason. To use it, cancel on the membership page and tell us through the contact page that you are cancelling within your 14 days, or send us any clear statement that says so.

When you join, you ask us to start your membership straight away. So if you cancel within the 14 days, we refund what you paid less a fair amount for the days you had, and we pay it back to your card within 14 days of hearing from you.

Nothing in these terms takes away the rights UK consumer law gives you. TrainerLens must be as described and provided with reasonable care and skill; if it is not, you may be entitled to have it put right or to money back.

Demo codes

A demo code gives a free membership, either for a set number of months or for good, as the code says. No card is asked for and nothing is charged.

When free months run out, the membership simply ends. You are never charged unless you choose to add a card and carry on as a paying member. A code works once, is for the person it was sent to, and has no cash value.

Your trainer is artificial intelligence

Please read this section carefully. It explains what TrainerLens is and what it is not.

  • You are dealing with a computer program, not a person. The trainer's cues, reviews, plans, suggestions and answers are written automatically by an artificial intelligence model. The voice you hear is made by a computer. No human trainer watches your workout or checks what the trainer says before you hear it.
  • It can be wrong. Artificial intelligence can say things that are inaccurate, incomplete, out of date or simply made up, and it can say them confidently. What it tells you may not suit your body, your fitness, your injuries or your health.
  • It is not a professional. The trainer is not a doctor, a physiotherapist, a dietitian or a certified personal trainer. Nothing it says is medical, health, nutrition or other professional advice, a diagnosis or a treatment.
  • It does not know you. It knows only the numbers your device measures and what you tell it. It does not know your medical history, it cannot feel what you feel, and it cannot tell when something is hurting you.
  • The camera tracking is also artificial intelligence. It estimates where your body is from the camera picture. It can miss a rep, count one that did not happen, or misjudge your form, especially in poor light, at an odd angle, in loose clothing, or when part of your body is out of view. Do not rely on it to keep you safe.
  • You decide. Treat everything the trainer says as a suggestion. You are responsible for deciding whether an exercise, a weight, a pace or a number of reps is right and safe for you. Never start, continue or push through anything that hurts or feels wrong because the trainer told you to.
  • It is not for emergencies. TrainerLens cannot get help for you. If you feel faint, have chest pain, cannot catch your breath or are hurt, stop and call your local emergency number.
  • No promised results. We do not promise weight loss, strength, fitness or any other result.

The trainer's words are written by an AI model from Anthropic working for us. What is sent to it, and what is never sent, is set out in the privacy policy. Do not tell the trainer anything you would not want handled that way.

Exercise is risky: you accept the risk

Exercise is physical and it can hurt you. The risks include muscle strains, sprains, torn ligaments, broken bones, falls, injuries from weights or equipment, heart problems, and in rare cases serious injury or death. These risks exist even when you do everything correctly, and they are higher when you train alone at home with nobody there to help.

Before you start, check with a doctor, especially if you have a heart, blood pressure, joint, back or other health condition, an injury, are pregnant or recently gave birth, are over 40 and not used to exercise, or have been told to limit physical activity. Clear the space around you, use equipment that is in good condition, warm up, and stop at once if you feel pain, dizziness, shortness of breath or anything else that is not right.

By using TrainerLens you agree that:

  • you are taking part by your own free choice, and you are fit and well enough to do so;
  • you understand the risks described here and you accept all of them, known and unknown;
  • you alone choose what you do, where you do it and how hard you push, and you are responsible for your own safety and for the safety of your space and equipment;
  • as far as the law allows, you give up any claim against LeoTech Services LLC, its owners, staff and suppliers for injury, illness, death, loss or damage that comes from your training, from using TrainerLens, or from relying on its counts, its form feedback or the trainer's words, including where the claim is that we were careless; and
  • this agreement also binds anyone who might bring a claim on your behalf, such as your family or your estate.

This section does not apply to harm we cause on purpose or through gross negligence, and it does not take away any right the law says cannot be given up. If you live in the United Kingdom, see "What we are responsible for" below.

Your account

You sign in with your email address and a six-digit code we email you. Anyone who can read that email can sign in as you, so keep it to yourself.

You must be 18 or older to use TrainerLens. By joining you confirm that you are. One membership is for one person.

You can take a copy of your data or delete your account at any time in Settings. Deleting your account does not by itself cancel your membership, so cancel first on the membership page.

Rules for using TrainerLens

Your membership is for your own personal training. You agree that you will not, and will not help anyone else to:

  • share or resell it: share your account, let other people train on your membership, or sell or rent access to TrainerLens;
  • get around payment or limits: avoid paying, reuse or trade demo codes, open extra accounts to get more than one person's fair use, or try to get around the limits on how much the trainer can be used;
  • cheat it: feed it recorded, altered or computer-made video in place of your own live camera, or otherwise fake reps, records, points or progress;
  • automate it: use bots, scripts or any automated tool to use TrainerLens, to copy or collect its content, or to send it requests faster than a person training would;
  • misuse the trainer: try to make the AI trainer ignore its instructions, reveal how it is set up, say harmful or offensive things, or do anything other than coach your training; or use it as a general-purpose AI service;
  • break into it: probe, scan or test TrainerLens for weaknesses, get around any security or access control, reach another person's account or data, or interfere with or overload the service;
  • take it apart or copy it: copy, change, decompile, reverse engineer or try to obtain the code, the models, the exercise library or the trainer's instructions, or use anything from TrainerLens to build or train a competing product or an AI model;
  • break the law: use TrainerLens in any way that is unlawful or that harms us or anyone else.

We watch for misuse. If you break these rules we may limit, suspend or end your membership at once, and where the misuse is serious we do not refund what you have paid, unless the law requires it. If your misuse causes us loss or a claim from someone else, you agree to cover that loss as far as the law allows.

If you find a security problem, please tell us through the contact page and do not use it or share it.

The service

We keep improving TrainerLens, so features can change. We work to keep it running, but we cannot promise it will always be available, free of mistakes, or that every count, cue or answer will be right. As far as the law allows, TrainerLens is provided "as is", without any promise beyond what these terms say.

To keep the service fair for everyone, there is a generous limit on how much the trainer can be used each day and each month. The app tells you if you reach it, and counting and form feedback carry on.

TrainerLens, its name, its design, its content and its software belong to us. Your membership lets you use it for your own training; it does not give you any other rights to it.

What we are responsible for

As far as the law allows, we are not responsible for injury, loss or damage that comes from how you train, or from relying on the counts, the form feedback or the trainer's words; we are not responsible for losses we could not reasonably have expected; and our total responsibility to you is limited to what you paid us in the twelve months before the problem.

Nothing in these terms limits our responsibility for death or personal injury caused by our negligence where the law does not allow that to be limited (which includes the United Kingdom), for fraud, or for anything else the law does not allow us to limit. Nothing here takes away your legal rights as a consumer.

The law that applies

These terms are governed by the law of Florida, United States, and disputes are heard by the courts there. If you live in the United Kingdom, you keep the protection of UK consumer law and you can bring a claim in the courts where you live.

Before going to court, please contact us. Most problems can be put right quickly. If any part of these terms cannot be enforced, the rest still applies.

Changes to these terms

When these terms change in a way that matters, we email you, and the app shows you the new version and asks you to agree before you carry on. If you do not agree, you can cancel.
