After scanning the apk file, ImmuniWeb has found a unencrypted SQLite database. This is not created or used by us. Does anyone know where it comes from?

It doesn’t look like anything VoltBuilder would cause.

Looking at it, could it be the browser’s auto fill data?

Could be… We use the app as a shell to connect to our webapp. So if it is not voltbuilder/cordova then it may be the inAppBrowser plugin we are using.

It’s part of Google Chrome.

I think Cordova/Android swaps in a chromium browser plugin in place of the InAppBrowser in APK files. But InAppBrowser has been deprecated in iOS, so you should try to upgrade to WKWebView if you need an iOS app.
