Hi, Yes, the database can be stored on your server. And your server security won't be endangered by the app, because the app won't have the root access to your server. Instead it will just download the database(.csv) file via HTTP. Once completed, you would have the full ownership over the application. Anyway, I would love to hear more details about your application(number of screens, their design, app's functionality) before I confirm my bid. I'm an Android Developer with 5 years of experience, please take a look at my profile and work history for any additional details about me, and send me a message if you find my bid interesting. Thanks, Milan
