The direct answer
A phone is a terrible single point of failure. PDF export writes a field sheet on the device so you can print it, share it to another phone, or keep a copy in a folder that is not this app. Free includes 2 lifetime distinct-article exports (re-exporting the same article does not spend another). Premium is unlimited.
Generation is local. You open an article, export, and get a formatted sheet — procedure, warnings, the bits you would want on a clipboard. It will not replace the full library. It is the page you actually needed when the battery hits 4%.
This is also how you back up something you cannot afford to lose to an uninstall. There is no cloud document vault. If it matters, export it.
Free vs Premium export
Local files. No account. No server render.
