Where to host the notebook but maintain the data on a LOCAL machine in 2024

I have a jupyter lab notebook that works and I want to host it on a site where my team can access it BUT I don’t want the data to be on the hosting server. So I’d create the data on my local machine ( linux mint) and my team ( 2 people) would just see my notebook, the data would change behind the scenes.

to explain the use a little more clearly.

a cron process downloads a csv from a site and it gets cleaned to daily.csv

on my LOCAL machine I load up daily.csv into a pandas dataframe in a jupyter lab notebook

I do jupyter lab stuff on the df_daily

I want to allow my team to play with the data BUT I don’t want to mess around with DMZ or other security stuff. I’d prefer to just “send” the data to a hosting service. I don’t like the look of google colabs as I don’t trust them. Kaggle is a option but I’d like to know if there are any alternatives that are simpler. I could crank up a linode server but that means I have to maintain ANOTHER environment. Anyone got a 2024 solution that works for the lazy and ignorant people like me?
