Hello Omar
There are many ways you can store your data on the internet and you can Google-search them on this forum:
TinyWebDb
CloudDB
Google Sheets
My SQL
CSV
...and more
You can store the data on your own Web Server, on an App Specific Website Service, on Google Drive ...and more.
If your PC has bluetooth and a bluetooth Desktop program that can receive your data, you can share that way, or via a USB cable connection, or simply by writing a file to a removable SD card.
Your choice will be made around the use of the App:
- How often is a measurement data set made
- How big the data is
- How many Users of the App
- How many Users with access to the data
- How important security of the data is
