Basically, sciebo is intended for storing and sharing data from study, research and teaching only. Apart from this, your institution decides what data you may store on sciebo. Usually this depends on the need for protection of certain types of data and is communicated in form of directives or regulations.
We encrypt the communication channels with SSL. Files on the sciebo servers are not encrypted as this would limit the service's functions. You can encrypt data which is particularly worthy of protection before uploading with external tools such as Boxcryptor or Cryptomator.
Our storage systems are very well protected from data loss through technical measures. Data that you have accidentally overwritten or deleted yourself can be easily restored in the web interface within 60 days using the versioning function. Still, we strongly recommend to make an external backup of important data.
