I maintain a local calendar on my LAN that I would like access to on Proton on the go. I am currently syncing the ical file to my phone, but there is no way to configure the android app to automatically read/import a local ical file.

Right now, in order to achieve this I would need to punch a hole in my firewall and make my calendar publicly accessible.

Several potential solutions:
- Allow the android app to read local files in the same way that public ical files can be imported
- Another option could be something like proton bridge that maintains synchronization between the local file and the server that could be run on a home server (but this is more complicated).
