Your blood pressure readings

The chart is calculated in your browser. We do not maintain accounts or a database of readings. Your reading also appears in the result page address, so it may be included in browser history and technical request logs. Avoid sharing that address if you want to keep the reading private.

Optional AI explanations

Only if you select the sharing checkbox and request an explanation, your reading, chosen country and age range are sent to our server, then through Lovable AI Gateway to OpenAI to generate a response. These details can be health-related personal data. You can use the chart without this sharing.

We do not save readings or explanations in our application database. The AI Gateway and hosting service may process request metadata and logs according to their policies; the model is called with storage disabled. This does not mean that no operational logs exist. Read Lovable's privacy policy and OpenAI's privacy policy. Processing may take place outside your country.

Your permission applies to the explanation you request, not to advertising cookies. Stop cancels an active request where possible but cannot undo information already sent. To withdraw permission for future explanations, clear the checkbox or do not request another explanation.

Cookies and Google ads

This site may show ads from Google (Google AdSense). With your permission, Google and its partners use cookies and similar technologies to show personalised ads and measure how ads perform. If you refuse, any ads shown are non-personalised. Google's use of data is described at policies.google.com/technologies/partner-sites.

Visitors in the UK, EU/EEA and Switzerland are asked first. Your choice (accept or reject), the date and the version of the notice are saved in your browser's local storage, not on our servers.

We also measure visits with Google Analytics. Until you accept, Google Analytics runs in cookieless measurement mode and cannot identify you; after you accept, it uses cookies to count visits and see which pages are used. Google's use of data is described at policies.google.com/technologies/partner-sites.
