Well that's one reason to not use a subscription based app. In the situation of a one time paid app a normal user would continue to use the same app, a power user would know it's a simple zip file. If you use a subscription based app you may not renew and you may be shit out of luck. A normal user may not even know what an HTML file is, much less how to edit it with a different program.
If you don't renew you can still use the app and open and edit all your existing notes. Good point, I need to make this more clear on the site. HTML vs. ZIP vs. power user: I'm going for the most common denominator, the average user with a browser :)
