Terms and conditions

1. Information only, not medical advice

The chart, tools, guides and blog on this site are general information. They are not medical advice, diagnosis or treatment, and they are not a substitute for a doctor. Always talk to a qualified health professional about your own blood pressure. Never start, change or stop medicine because of anything on this site.

2. Emergencies

If you or someone else has chest pain, sudden weakness, trouble speaking, severe breathlessness or collapses, call your local emergency number immediately. Do not use this site to decide whether to seek emergency help.

3. Accuracy

We base thresholds on published guidelines listed on our medical review page. Guidelines change and differ between countries. We try to keep the site current but give no guarantee that it is complete, accurate or up to date. A result on the chart does not take account of your health history.

4. Use at your own risk

You use the site at your own risk. To the fullest extent allowed by law, we are not liable for any loss or harm that arises from using, or being unable to use, the site or relying on its content.

5. Your data

Readings you save are stored in your browser only. You are responsible for your device and for deleting data on shared computers. See our privacy policy.

6. Intellectual property

The text, design and code of this site belong to us unless stated otherwise. You may print pages and charts for personal or family use, and for sharing with your doctor or carer. You may not copy the site for commercial use without our written permission.

7. Links to other sites

We link to outside sites such as the NHS. We do not control them and are not responsible for their content.

8. Changes

We may update these terms. Continued use of the site after a change means you accept the new terms.
