Website does not inspire trust as there is no mention at all about who the seller is.
Terms of use, privacy policy are also relevant, especially in this context where software gets access to all of customer's data...
First time software seller here so I'm a little slow on some things but rest assured, I'm gonna have a privacy policy soon. The EULA is there when you download the software.
BlobBackup doesn't store any user data anywhere other than the user's computer and their backup storage though (and this is encrypted).
