FAQ

Questions, answered plainly.

Short answers, with links to the detail.

The basics

What is VITAL?

VITAL REBUILD is a personal health intelligence product. It brings together the files you import and the readings you type in, and shows what has changed for you — compared with your own history, with each value labelled by how it came to be.

Is VITAL medical software?

No. VITAL is wellness information, not medical advice. It does not diagnose, treat or monitor any condition, does not assess exercise clearance, and does not prescribe exercise. It is not an emergency service and does not watch your data for emergencies or alert anyone. If you feel unwell or worried, speak to a health professional; in an emergency call your local emergency number.

Who can use it, and what does it cost?

VITAL is free to use. Accounts are for people aged 18 or older, and registration is controlled. See Account.

Is it available as a phone app?

VITAL is a web application that works in a phone browser. This site’s screenshots include the phone layout.

Your data

Where does the data come from?

From file import — FIT, TCX, GPX, an Apple Health export, and CSV for weight or blood pressure — and from readings you type in. See How it works.

Does VITAL connect automatically to devices or other services?

No. File import means VITAL reads a file you provide. It has no automatic device sync: not Garmin, Strava, Apple, Fitbit, Polar, Suunto or similar services. You use manual entry and supported file imports.

What do Recorded, Calculated and Estimate mean?

Recorded: measured by a device or entered by you. Calculated: a deterministic calculation from recorded values. Estimate: an inference, with its evidence and uncertainty stated. Values you typed in are Reported by you. See the full list.

Why does VITAL say “lower” instead of “worse”?

Whether a change matters depends on context — your health, your routine, your medication — that only you have. VITAL shows higher or lower and does not label the direction good or bad.

Why does it sometimes show no verdict?

A comparison needs a minimum number of readings or days in each window. Below that, VITAL shows the counts and no verdict. Where data is missing it says so rather than estimating.

Does an association mean one thing causes another?

No. Exploratory associations show their sample counts and limitations, and are never presented as causes.

What is VCI?

The Vital Capacity Index is an experimental score from 0 to 100 for how far you have recently walked or run continuously, taken from your own sessions. It is an estimate with a stated confidence. It is not a clinical measure, a VO2 estimate, clearance or a prediction. See VCI.

Privacy and control

Do you sell my data or show ads?

No. VITAL does not sell health data, does not use it for advertising or research, does not pool it across accounts, and does not send your records to third-party AI services.

Does this website use cookies or trackers?

No. There are no cookies, no analytics and no third-party scripts, fonts or requests, so there is no cookie banner.

Is my data encrypted?

VITAL is not end-to-end encrypted. The person who operates the server can technically access stored data. The privacy page lists the limits plainly.

Can I export or delete my data?

Yes. Export gives you a zip of JSON files covering every table of your database. Deleting your account removes your database at once. Some registry records remain, and copies can stay in encrypted backups for up to about six months. See what remains and why.

Access and sign-in

How do I get an account?

The VITAL app is not open to new accounts yet. When it opens, you sign up from the app while registration is open, and new accounts are opened in limited numbers. See Getting an account for the steps.

I forgot my password.

This website has no passwords. Recovery is handled by the sign-in service — see Account.

Who do I contact?
