Certainly this model would result in a lot more people who would create accounts to test and never come back after deciding it's not for them. The answer to that is a clear dormant account policy - for example by deleting free accounts after 60 days with no login. That helps make sure that all your trial users are actively engaged in using the service, and also gives you an opportunity to follow up with dormant users at defined points to remind them that their account will expire if left unused, and giving the opportunity to upgrade to a paid account which has no such limit.
Another person mentioned that 5MB is a lot for text notes, which is quite true - following the notion.so approach and having a limit of 100 notes or so might be more sensible. I personally just don't like the idea of a time limit on a note taking app, especially when all the other options provide a free quota instead.
That said, your pricing looks just right for me, and the lack of the web app is the main thing stopping me from giving it a try. I really like the fact that you have both folders and tags, instead of just one or the other - that's really the one thing I feel is missing from both Standard Notes and Notion
