Our servers - operated in Germany - are very safe. If you have saved your account under your email address and password, your data is not gone, even if that appears to be the case. In this situation, please carry out the following steps:

1. Please check your internet connection. Your data can only load correctly with a stable internet connection.
2. Log out of the app, close the app completely and open the app again.
3. If this does not help, please delete the app from your phone/tablet and download and install the app again.

If your data are still not shown properly, it's very likely that you were logged in with another YAZIO account before and used that one to make your entries. Please log in with your other account and check whether your data are shown there. In case you are not sure if you have another account, please send us a message, in which you mention your date of birth and your body height. Then we will investigate if there is another account registered.

Note: For maintenance purposes, sometimes it may be necessary to restart or shut down our servers temporarily. This could cause your data to temporarily disappear for several minutes. So, please try again later. In very rare cases, it may also be necessary that we need to restore a data backup. If this is the case, the data you entered in the last few hours might have been lost. However, our backups are generally a maximum of four hours.

We hope that you were able to find answers to all your questions and wish you a great journey with YAZIO.
