Thanks for answering them, but I have a follow up question to the 2nd one
If everything is stored locally that means the photos and videos that I upload will start occupying a lot of space in a few months from now on the local storage. I am okay with them taking up a significant space on my personal cloud storage (since I always have the option to upgrade plans) but on my PC I have very limited storage. So what can be done in such a case ?
And one more thing. I didn't exactly get it. Are they stored locally in their original form or in encrypted form (in database) so that they won't occupy much space ?
