Yep, I agree completely. I work on a relatively well known app, and we use Crashlytics to monitor crashes (duh), and other tracking software to reduce friction in the app.

We don't care who tapped button A instead of button B, we just want to know how many people tapped button A instead of button B.

You don't care, but we can be reasonable sure that Crashlytics has access to that data.

Even if they don't use it that with ill intent themselves (there's really no way to know one way or the other), we can also be reasonably sure that it won't stay secure with them forever.

All the data is anonymous, though: the only identifying info we're sending them is an internal Customer ID.
