Privacy policy

Who we are

TrainerLens is run by LeoTech Services LLC, a company in Florida, United States. We decide how your data is used, which makes us the "controller" of it. You can reach us about anything in this policy through the contact page.

Your camera picture never leaves your device

The body tracking is artificial intelligence that runs on your phone or computer, inside your browser. Each frame from the camera is looked at there and then thrown away. No picture and no video is ever recorded, saved, or sent to us or anyone else. The camera's microphone is not used.

What the tracking works out from the picture is numbers: where your joints are, joint angles, rep counts, depths and timings. Only those numbers are used by the rest of TrainerLens. They are not used to identify you, and no face or body template is made or kept.

What we keep

• Your email address, to sign you in and to write to you about your membership.
• Your training: your workouts and sets, the numbers from each set, your saved workouts and programme, your progress and your settings.
• Body details you choose to enter: weight, height, age and sex. They are used for calorie estimates and to fit the coaching to you.
• Your trainer conversation: what the trainer said to you and the questions you asked, so you can look back at them.
• Membership records: that you are a member, when you joined, what you paid and when. Your card details go straight to Stripe, our payment company. We never see or keep your full card number.
• Messages you send us through the contact page, with the name and email you give.
• A record of use: how much the trainer has been used on your account, and the internet address your requests come from, to keep the service safe and fair.
• A record of visits to this website: which pages were opened and which steps of joining were reached, the site you came from, any campaign tag on the link you followed, and whether you were on a phone or a computer. It holds no name, no email and no internet address. Visits are told apart by a code worked out from your internet address and browser type, and that code changes every day.

We use one cookie, which keeps you signed in. It is needed for the app to work. There are no advertising cookies, no analytics cookies and no tracking across other sites.

Why we use it

• To give you the service you joined: your account, your membership, your training history and your trainer.
• With your consent: your body details and the measurements from your workouts are used to coach you. You give this consent in the app, and you can take it back at any time by turning the trainer off or deleting your account.
• To keep the service safe: to stop misuse and to fix problems.
• To see how people find us: the record of visits shows which pages, links and adverts bring people to this website.
• Because the law requires it: we keep payment records for tax and accounting.

Who else handles it

These companies work for us and handle only what their job needs:

• Anthropic writes the trainer's words. It receives the measurements from your sets, your body details where they matter to the coaching, and the questions you ask. It never receives a picture, and never your email address. Under its business terms it does not use this to train its models.
• A speech service run for us turns the trainer's words into a voice. It receives only the text of each line.
• Microsoft Azure hosts the app, the database and our email sending, in the United States.
• Stripe takes payments and keeps your card details.

If you speak a question instead of typing it, your browser turns your speech into text. Some browsers send the sound to their maker to do this, for example Google for Chrome. We receive only the text.

We do not sell your data, share it for advertising, or use it for anything other than running TrainerLens for you. We would share it if a court or the law required us to.

How long we keep it

• Your account and training are kept while you have an account. Deleting your account removes them.
• Payment records are kept for as long as tax law requires, usually seven years.
• Messages from the contact page are kept for up to two years.
• The record of visits to this website is kept for up to two years.
• Sign-in codes last ten minutes.

Your choices and rights

• Take a copy of everything we keep about you, in Settings in the app.
• Delete your account and everything stored with it, in Settings in the app.
• Turn the trainer off in Settings. Then nothing about your sets is sent to write the trainer's words.
• Ask us to correct your data, to stop or limit a use of it, or to answer a question about it, through the contact page. We answer within one month.

We do not treat you differently for using any of these rights.

If you live in the United Kingdom

UK data protection law gives you the rights above, and the right to object to a use of your data and to withdraw consent at any time.

Your weight, height and workout measurements can say something about your health, so we use them only with your explicit consent.

Your data is stored in the United States. When we send it there, we rely on the safeguards UK law accepts for such transfers.

If you are unhappy with how we have handled your data, please tell us first so we can put it right. You also have the right to complain to the Information Commissioner's Office at ico.org.uk.

Consumer health data

Some US states, including Washington, have laws about "consumer health data". This section is our notice under those laws.

• What we collect: the body details you enter (weight, height, age and sex), the measurements your device works out from your movement (joint angles, rep counts, depths, timings), calorie estimates, and what you tell the trainer about your body or training.
• Where it comes from: from you, and from the body tracking that runs on your device.
• Why: to count your reps, coach your form, plan your training and show your progress. Nothing else.
• Who it is shared with: Anthropic, to write the trainer's words, and Microsoft Azure, which hosts it. They may use it only to do that work for us.
• We never sell it.
• Your rights: you can ask what we hold, take back your consent, and have it deleted, in Settings in the app or through the contact page. If we refuse a request you can ask us to look again, and you can contact your state's Attorney General.

Age

TrainerLens is for adults aged 18 and over. We do not knowingly keep data about anyone younger. If you believe someone under 18 has made an account, tell us and we will delete it.

Changes

When this policy changes, we change the date at the top, and the app shows you the new version and asks you to agree before you carry on.
