Projects are stored both locally on the mobile device and on a secure server.
If a project appears on your mobile device and you are not logged into your account, it means those projects are stored locally on the mobile device.
To sync with the web application, verify you have a stable WiFi connection, log into your account, and tap the cloud icon next to the project name to upload data.
Uploading data from different mobile devices to the same project will not override the data. Data sets will be added to the existing ones.
If a project appears on the web application but not on the mobile device, log into your account from the mobile device and swipe from top to bottom on the project list page to synchronize projects.

Administrators and Study Managers can view all projects within an organization. Operators can only view projects on which they have collaborated or projects stored locally on the mobile device.

Deleting project sessions before they have been uploaded to the Cloud will delete locally stored data. This process is not reversible.
