Sorry @jalucky13, can’t include links in posts. It’s called “App Manager” on F-Droid. https://f-droid.org/en/packages/io.github.muntashirakon.AppManager/
I found it. Those 2 trackers are in every Mudita app but 0 trackers in the doss equivalents!

I can’t believed mudita hasn’t responded to something so against everything they have marketed. @urszula

@htoke Can you give me more info as to what exactly the concern is? Forgive me, but I’m not sure I follow.
@urszula The mudita apps are emitting rf/emf radiation because they have a tracker running, thus hurting privacy, battery life, and potentially causing health effects

@htoke Thank you for the clarification. I will ask the team and get back to you. I don’t have much knowledge on these issues, I’m afraid.
Maybe I should have added that Sentry is a widely used tool for error tracking, so not necessarily nefarious.
@urszula Mudita apps apparently log at least every app start via Sentry in real-time to a remote system. Confirmed with packet-capture and Calculator app. We cannot easily see what’s in the transmissions without breaking encryption.
IMO this is a bit much, and should be opt-in. Please ask before using my network

@pok I’ve asked our team for feedback on this. So, I’ll get back as soon as they answer.

I’ve asked our Managing Director @michalstasiuk to jump on here when he has a chance, in order to give some more insight into what is happening.

That’s wonderful, would be great to have some clarity on this! I was actually going to make a post about this, but it’s nice to see that there’s already been discussion about telemetry.
I downloaded Rethink (Rethink: DNS + Firewall + VPN | F-Droid - Free and Open Source Android App Repository) a couple of weeks ago out of curiosity. I was happy to see that the default apps are mainly connecting to Sentry, which seems like a commonly used analytics provider, just as @pok mentioned. The amount of data sent/received isn’t a much so the apps are just pinging the server, but I’m still a bit concerned by a sheer number of connections. The launcher app seems to be connecting the most, presumably because it’s the one that’s most interacted with.
Here’s a screenshot showing some stats from the past 7 days, Launcher with 480 connections to Sentry. Sounds a bit excessive?

Hi everyone, I’d be happy to clarify things.
A phone that is powered on and in online mode maintains regular communication with cellular base stations. This is unavoidable due to how mobile networks work. It happens even when no apps or services are actively using the internet. The best way to eliminate EMF emissions from the device is to switch the phone to Offline+.
We use Sentry solely to collect data that helps us fix software bugs. The following types of data are gathered:
- Error logs
- Time zone
- Battery status (power level, temperature)
- Free memory
- Connection type (Wi-Fi or cellular)
- Software version
- Boot time
We do not collect any personal information or data that would allow us to identify a specific user or device. I hope this explanation is helpful and provides more clarity.

Yes but the mudita has constant rf so its constantly connecting to something. I checked it with my rf meter as you can see in my video. My iphone and moto g 2025 doesn’t do this. It is mudita’s apps doing it because once I disabled them and installed foss equivalents from fdroid, its totally stopped!

Thanks for chiming in, @michalstasiuk. What’s your stance on making this data collection optional, considering even the big players at least let you opt out? Then it’s no longer unavoidable transmissions.
To be frank, that’s a dealbreaker for me. I would so love to recommend this awesome little machine to friends and family, but currently I’m a little on the fence, to say the least.

I’m gonna play devil’s advocate here 
So here me out
@pok This could be a bit risky for the user- especially with a brand new product that’s just being refined. Imagine we do offer this & you chose to turn this function ON & stop any data/log collection. All is well, until something happens & the camera apps keeps crashing or perhaps it stopped saving your pictures altogether. You come on to the forum to report this issue, but, unfortunately, our team cannot help because we cannot recreate the problem, in order to figure out what’s happening to fix the bug.
Yes, someone else can come along with the same issue, and they happen to allow this info to be collected, and then YES, our team could recreate the bug & fix the problem fairly quickly, or offer a solution. HOWEVER, what if this person is not on the FORUM or this is an isolated incident in your phone. Then there is a risk of getting stuck with the glitch which we cannot readily fix because we don’t know what’s happening.

I can see it collecting information every now and then like once a day but it’s constant. My radios never turn off when any mudita app has been used. Even when I go to the home screen, it still is pinging constant rf! If I go into settings and stop the app it stops the rf. So something is weird. This should be really easy for the team to duplicate using an RF meter.

Thank you for your thoughts, @urszula! I understand the need for data, but IMO, there shouldn’t be a conflict of interest: You could put a checkbox somewhere saying you collect this and that and why. When I disable it, it pops up a big scary warning, saying what you stated above. It could even include an invitation to the forum! Assume your paying customers are grown-ups and owners.
That would feel friendly, consensual and on eye-level. It’s how trust is built - I would certainly be willing to contribute data in that scenario to help you improve.
If I may say so, it’s also partially beside the point, since tracking every Mudita app start in real time is unlikely to help you find bugs, so that should be a separate option.
Anyway, huge kudos for taking part in this discussion so openly, highly appreciated!

Data collection isn’t necessary to recreate a bug. Plus I thought part of the Mudita philosophy was giving users control over their devices. Sideloading apps is more likely to cause issues that restricting us to the base apps but we’re still able to do it. This should be no different.
Not only is it unnecessary to resolve bugs (it might help track trends on a large scale but it’s not necessary to resolve an individual user’s issue), as a user I should be able to assume the risk. If I decide that lower EMF, reduced battery usage, and less tracking are worth the risk, then it’s mine to take. If down the line that does somehow make it harder to fix an issue, that’s ok because I knew that risk when I turned off the analytics.

@bone_naga I totally get where you’re coming from. I’m not super technical, so I’m just passing on the info that our team has given me That’s why I asked our Managing Director @michalstasiuk to jump on here to perhaps clear this up, so that we’re all on the same page.

If this wan’t the case, this response would be satisfactory. In light of this however, it seems like there is a bug or something else fishy. @urszula @michalstasiuk please respond to @jalucky13’s findings.
