I went into the app store to see about this app, having not heard about it yet. The app's privacy policy says it uses Firebase (Google) Analytics, which transmits information about your use of the app off the device without consent.

This, to me, means I can never trust it for scanning sensitive or private documents, because who knows what it's sending. I declined to install it. YMMV.

This is in the context of scanning homework assignments.

Not to mention-- Firebase tracks what, events? You think somehow it's encoding the documents in an event stream to exfiltrate them?

An app that shares my event data silently and without consent cannot be trusted with even low-grade private information. Why would I ever allow it on a device that handles high-grade private information?

It's neither silent nor without consent since you were told about it.

> An app that shares my event data silently and without consent

You're complaining about a -disclosed- use of analytics.

It seems like you'd be happier with an app that just didn't mention the use.

It's not without consent nor is it silently. You consent when you decide to install it and it's not silently if they just told you that it happens.

Can you not just block its internet connection?

Not conveniently on iOS.

Ah, that's unfortunate.
