Curious, the #COVIDSafe source contains a handful of references to the SG gov namespace complete with typo. Doesn't match the Play Store's live ID/namespace for AU or SG apps though. Haven't found any other references either. ImageImage
I'm dealing with a decompiled version of this app but it seems *very* crude and thrown together. Lots of things referencing multiple points of configuration with some parts being configured, others hard coded, others generated. Very inconsistent.
This seems like a sub-optimal way to delete data older than 21 days ago... bu that could also be the decompiler not noticing the int constants are from Calendar.HOUR_OF_DAY etc. Image
So after a bunch of digging, I can't find any indication there was ever intent to collect or store additional data. As far as the app is concerned it sees to be intentionally light on the fields. Age, postcode, phone number - thats it.

This is a good thing!
Had a few messages asking questions - I'm not digging into any network stuff. Purely looking at the app and what anyone with a stock standard android decompiler and google can do. I look forward to digging into the privacy assessment, security audit and source code once it's out.
Also, to the people asking "how can I do this too", my suggestion is: don't.

I don't want to undermine this app, I'm curious and want more skilled scrutiny. Unless you already know how Android works, the risk of alarmist misinformation is too high. 1/4
So far, I've found nothing dangerous, and plenty of indicators that is was rushed, but with good intent.
On the whole, it seems quickly put together, functional and not-terribly architected. Yes, it implements its own tracing not Google/Apples algorithm - but we knew that! 2/4
I cannot see a *technical* reason why someone shouldn't install #CovidSafe; I just think its short sighted not to wait until the official Bluetooth API from Google & Apple. This is especially relevant for people who have to work and would benefit significantly more from it. 3/4
Personally, I still don't trust the Federal Government to implement anything like this so quickly without oversight, and I'm isolating at home too. I'll be waiting for the Google + Apple API to be released *and* adopted proof points that its implemented in #CovidSafe 4/4
