When I uninstalled the previous version of Pi i made sure to delete all the files. But on installing the 31Oct version, I found that
1) It didn't ask for activation code.
2) It remembered my user id.
3) It remembered my marketwatch and the layout including graphs.
So my question is : How did these settings remained saved even after uninstalling and deleting files ??
Is Zerodha secretly saving the settings somewhere in my PC or at their end ? Uninstalling and deleting should clear all the history of a software.
