All documents are archived highly encrypted in the central digital database. This database receives a unique MasterKey to comply with Zero-Knowledge technology guidelines.
Without this MasterKey, your database can not be accessed. Only you own this MasterKey, which is generated once each database creation. You should keep it carefully and not pass it on to third parties.
If it should happen that you should disconnect from this database, you will need this MasterKey because you will be asked for this key when reconnecting.
