I totally agree with the idea of having it all vanish. I’m still building it out, but I’m working towards an ‘eject button’ where you can download all of your notes into a CSV and get out of dodge if you choose!
This won't really help. The point of an SRS is the scheduling information. Even then, you may not have a compatible system to make use of the scheduling info. The switching cost is immense, and I would personally need an ironclad guarantee that the tool cannot be taken from me, such as by having the source code. Never going to be using a non-self hosted SaaS for this, sorry. There is a lot to dislike about Anki but the good thing is it will be only taken from my cold dead hands.
