I’am concerned about my data :
First I understand I need to trust RemNote, but it will be really usefull to have cypher block (with password), I understand that this will not be searchable
I backed-up my knowledge base and was surprise I can’t read it with the application on a off-network computer.
The app to be runned need to connect to internet. So It must say that I you are offline, I can’t install the app and work on my database. This is a big problem !! Even with a local one !
Finally it seems you need to clarify your export option, they are not exploitable except if you are a developers. The minimum would be to produce a ZIP file with markdown or html and include correctly the attachments. (maybe you could limit it to one by month, cause I understand it will cost bandwitch and cpu)
