What we know about you

This app asks you about injuries and medication, so you are owed a straight answer about where that goes. No legal padding — this is what the app actually does.

What we hold

What you tell us about your body

Your age, sex, height, weight and target weight. These are what turn a generic calorie figure into a real calculation — without them the app is guessing, and it says so on screen rather than pretending.

What you tell us about your health

Injuries, pain you flag during a workout, medication you mention, and — if you track it — your menstrual cycle. This is the most sensitive thing here. It exists so the app can route exercises around a bad knee, hold you off heavy loading when that would be unsafe, and stop prescribing a calorie deficit to somebody who should not be in one.

What you do in the app

Your workouts, sets, reps and loads; the meals you log; your weigh-ins and check-ins. This is your training history and it belongs to you.

How to reach you

Your name and email address. A phone number only if you gave one.

If you sign in with Google

Google sends us your name, email address and profile picture, and nothing else. We cannot see your Gmail, Drive, contacts or anything else in your Google account, and we never post to it.

Who can see it

You

All of it, any time, from your profile.

Coach Miguel

Your coach can see your training, your intake answers and your health flags. That is the point of having a coach — he cannot write you a safe programme without them.

Nobody else

Your data is not sold, and it is not shared with advertisers. Other members of the app cannot see your health information, your weight or your logs — only what you deliberately post to the Round Table.

The services that run the app

Supabase stores the data and Vercel serves the site. When you use an AI feature, the relevant part of your profile is sent to the model provider with identifying details removed first — your name and email are replaced with an opaque id before it leaves.

What you can ask for

A copy. Your codex and your training history can be exported from your profile at any time.

A correction. Everything you answered in the intake can be edited from your profile, and the programme rebuilds from the new answers.

Deletion. Message Coach Miguel and your account and its data are removed. You do not have to give a reason.

Two honest limits

The AI scrubbing is good, not perfect.Names and contact details are removed from what is sent to the model. Free-text you write in a notes box — a diagnosis, a doctor's name — may travel with it. Bear that in mind when you type into a notes field.

This is coaching, not medicine. Nothing here is a diagnosis. If something hurts or you have a condition, the app will tell you to see a doctor, and it means it.
