Does LocalDB on Pen drive has Traces on Desktop?

Hi,

I have desktop application using SQL Server LocalDB as database. Application is installed on desktop and Database is on Pen Drive.

I am accessing Database from application as :

data source=(LocalDB)\v11.0;attachdbfilename=H:\Database\CompetitorDB.mdf;

(H: is Removable Disk / Pen Drive)

My Question is :

1> Does Accessing Database in this way creates any local copy of Database on the desktop?

2> Does Accessed data through Application get stored in any form on the on the desktop.

3> If so then How can I avoid data traces?

Since I do not want any sensitive data/traces to be on desktop once I remove the pen drive in order maintain the security of information.

Thanks,

Manthan
