Terms of use

Not medical advice

HealthQuant is an informational self-tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Anything it shows — trends, averages, patterns — describes the numbers you entered, nothing more. Correlation is not causation: a reading running high on flagged days does not mean it causes anything. Always consult a qualified professional about your health, and never change medication or treatment based on this tool.

Your data is your responsibility

HealthQuant stores everything in your browser's local storage. There is no server copy. This means:

• Clearing your browser data deletes all of it, permanently. This is the single most common way tracking data is lost — export a backup (JSON) from the report page regularly.
• Private/incognito browsing discards your data when the window closes.
• Installing the site as an app or switching browsers creates a separate, empty storage.

No warranty

HealthQuant is provided "as is", free of charge, without warranty of any kind. We aim for accuracy in charts and summaries but make no guarantee that they are error-free. You use it at your own discretion.

Acceptable use

Use the tool for your own self-tracking. Don't rely on it as a sole record for anything medically or legally consequential.
