Host App that reads local Pickle Files

HI I have been using streamlit and its amazing !! My question is about how to go about given my current setup. My streamlit app reads pickle files from my local machine and I have another program that writes data to these pickle files, will this work? Or do I need to write my data and connect to an online db?

I attempted to deploy my app.py on the streamlit cloud but ran into dependency errors which I could not figure out how to solve for since I can’t seem to figure how to access the terminal : (

I had already used a streamlit app that read a pickle file it works, but I had never used a app that write any file, if test it, just tell me, please.
