How Secure are the apps on your Android cellphone?

Post by AZgl1500 »

there is a research firm that I ran across tonight that I used to find out about a few of my more "worrisome" Android apps.

One of which is my Evernote web app for storing my personal data.....
I am happy to report, that Evernote got a Clean Bill of Health.

Data Recipients

When this app transmits sensitive information, it is received by the parties listed in the table below. The second column indicates the data type each party receives, and the third column indicates whether or not the data was encrypted while in transit using TLS.

Warning: just because we did not observe a particular data type being transmitted during our limited testing period does not mean that the app definitively will not transmit it when tested under different conditions.
No third-party data sharing detected
------------------------------------------------------------

I got started on researching how secure my phone isn't by reading this article.

https://www.cnet.com/news/your-phone-ta ... tening-in/

which contains a link to https://search.appcensus.io/
which has a database of 17,000+ apps so far.

At first, I thought the link was broken, it isn't.
It is just plain and simple, SLOW....
it is donation supported, and apparently they can't afford a fast server, or their database engine is slow.

I also use another notepad app for quick and dirty notes Offline, and it Syncs to their servers once in a while.

Again, I was very pleased to see the last line: No third-party data sharing detected


==================================

What got me started on this search was this article that was released on Google News yesterday:

I am now going to look at a few other Android apps on my phone to see if they need to be deleted.

I used to have F-Droid loaded on my older Note4 phone, and the phone before that one.
then the Note4 met the Ugly Sun one day, when I laid it on the dash of my truck during a rainstorm....

about 4 hours later, with me in deep thoughts of watching the wildlife go by, the sun comes out, and the dash got really hot.
that phone never did awaken again.

I lost a lot of data that day, but I was lucky enough to be using NOVA Launcher which creates backups of the phone's desktop.
got a new phone, and let Google's Playstore Apps reinstall all of the apps that they knew of ....
then went to my email and clicked on the latest NOVA backup.

5 seconds later, all of my desktop screens were restored....

found out the hard way, that some of my apps that were supposed to be syncing to the cloud, were not.
but, my Evernote was..... so all is well for personal info.

I will install F-Droid and get reacquainted with it.

I replaced the on-screen keyboard, photo and image editing programs and the music program with FOSS programs from f-Droid. In Google-specific programs, everything is "paused".
From the Google Store I only have Opera Mini, TextMaker BASIC, Lithium and the OKO light meter. None of these programs have ever sent me advertising or otherwise annoyed me.

Opera may be borderline, but it's simply the only browser that has a reasonable bookmark management.
Not to mention Total Commander: there is no substitute for that either.

Honestly, there's really no way to know. It's not like most of these apps are open source (in the technical sense relating to source code), so I see limited value in network traffic monitoring.

Besides, how are they monitoring actual network traffic? They would have to tap into all the cellular companies' networks, and somehow I doubt AT&T, Verizon, et al, would willingly allow that.

I use pretty much mainstream apps, most of which are Google-made, so I'm not worried about them having malicious trojan elements to them (i.e. virus laden).
Please be polite and remember to mark your fixed problem [SOLVED].

Presently running Linux Mint Cinnamon 19.3.

Know when what you're doing is trying to fit a square peg in a round hole, and STOP.

Still looking for a new job.

I was shocked when I discovered what the included Sony keyboard stores, e.g. also passwords. At least made me think ...
