Privacy policy

• There are no accounts and no sign-up.
• Readings you save are stored only in this browser, on this device. We cannot see them.
• Nothing is sent to a server when you check a reading. The calculation runs in your browser.
• Readings leave your device only if you print them or press “Share with family” and send the text yourself.
• We never sell health data.
