Privacy Policy

This is the privacy policy for BP Folio, made by 深圳市好多牛科技有限公司.

What BP Folio records

BP Folio is a manual blood-pressure log. The only information in the app is what you type in yourself:

The phone cannot measure blood pressure. You enter every number by hand from your own cuff.

Where it is stored

Your readings are stored locally on your iPhone. We do not operate an account, and we do not keep a cloud copy of your readings. Nothing is sent to us when you add or view a reading.

Uninstalling the app deletes the data on the device.

Export

You can export your readings as a PDF or CSV. The export file is created on the device from the numbers you typed, and you choose whether and how to share it. We never receive it.

We do not sell data

We do not sell your readings, and we do not share them with anyone. There is no advertising or third-party tracking built into the app.

Children

BP Folio is not aimed at children, and we do not knowingly collect information from children.
