Help! My data is gone!

Please first check whether the time range shown is correct. Under the "New entry" button you can see the period for which values were entered and the period currently being displayed. Is that correct? Sometimes an entry is accidentally saved with the wrong year, which then changes what is shown.

If that doesn't help, please check whether you're still logged in with the correct account. Your username appears in the title bar if there's enough room. You can also see your login by opening the menu and then clicking "User account".
Is that correct?

If that is your username, it's also possible that you entered the values as a guest by mistake. In that case you should see a "Guest" button in the top left when the app starts. Click it to switch to the guest account. Do you see the values now? If so, our support team can move these values into your user account for you. We will not be able to view the data when doing this. Please contact support@bloodpressuredb.com.
