Option to auto-delete uploaded files locally

I'm using cryptomator to upload photos to my cloud (hence to have access from my computer). I'd be very thankful if cryptomator offered the ability to auto-delete uploaded files locally after they are successfully uploaded to the cloud. I don't need them on the phone anymore since they are stored in the cloud.

Example for photos:
- go to gallery and select photos
- share with --> cryptomator ("encrypt")
- optional: select different "save location" and edit "file" names
- allow the user to select a checkbox which gives the ability to auto-delete uploaded files locally
- "save" --> upload starts, after success trigger deletion of photos on the phone

Small UX idea:
I personally prefer to have "save location" at the top and "files" at the bottom. Reason: "Save location" is more important than "files". Most people probably don't want to edit file names anyway, but to select save location. Scrolling down with lots of files takes some time and new users probably don't know the existence of "save location". The checkbox discussed above could stick right above the "save"-button.
