A non-cloud local calendar for Android? Is there any way to have and use a local calendar on Android?

I would like to use it on the Android phone and open the file (vcs, ics, anything) on my laptop sometimes.

I have not found any applications that deal with local calendar files stored on the SD-card of the phone. I have found only numerous cloud applications so far.

Is there any app that can open and edit local calendar files on Android?
Etar - Open source calendar app is what we needed.
