We are not in confinement. We can leave the flat at will any time between the hours of 6am and 6pm, for as long as we like and go as far as we like.
However, there is a curfew from 6pm to 6am. During this period if we are caught outside the flat we need a good reason, such as coming home from work, walking the dog, caring for a vulnerable person, etc.
Also the borders are closed to any country outside the European Union, so we can't go to the UK, for example.
Also anyone entering France from a EU country has to have a negative PCR test from within the last 72 hours.
All large shopping malls are closed, except for food retailers.
And the concert halls, cafés, restaurants, museums etc. are closed.
We avoid public transport more than we used to and although the weather is now much milder than in January, it's pretty wet, so buying take-out coffee and sitting on a bench somewhere isn't a very attractive option.
So I've taken to walking to one of the supermarkets every morning for enough shopping to fit in my backpack. Yesterday it was our local Carrefour, about 25 minutes walk away. This morning it was Lidl, about 20 minutes walk in a different direction. Lidl is nice because it is outside the mask zone, so you just have to mask up to go into the shop. Carrefour is about 5 minutes into the mask some so you have to mask up and demask in the street under the railway bridge.
I know this is what I always advised very elderly people to do, but hey - times are strange and we must adapt.
