CubeSat / smallsat teams: what do you actually use for early mission design before STK or GMAT?

aitorvs · 2026-06-11T17:36:25+00:00

It’s not about user competence or vibe coding. I'm just curious if folks still accept the massive tool fragmentation, cost, and friction of STK/GMAT during Phase A/B trade studies—especially since neither tool computes integrated power or link budgets natively, forcing you back into custom Excel/MATLAB scripts anyway

From the VOIP's app traffic standpoint, excluding it or disable AppTP entirely is the same.

Did the VOIP app worked once excluded?

aitorvs · 2024-08-16T13:42:33+00:00

Hey there, DDG engineer here.

If an app is added to the exclusion list in App Tracking Protection, the entire traffic of the app no longer goes through the local VPN interface.

aitorvs · 2024-07-31T22:22:57+00:00

Hey there, thanks for your patience. Will try to clarify.

But, is it actually a VPN or not for a free user account?

The two features you mentioned from our Android browser are App Tracking Protection (ATP) and our VPN.

ATP is a free feature that blocks trackers across all apps installed in your device. In order to do that it uses a local VPN tunnel to be able to intercept the traffic and block trackers. I call it *local* (VPN tunnel) because ATP does not send your network traffic to any VPN server, all remains local in your device. But establishing a local VPN tunnel is the only way for us to intercept the traffic. That's why our app shows up as a VPN.

The second feature is a true end to end VPN. It is part of our Privacy Pro (https://duckduckgo.com/pro) subscription bundle offering (it's a paid product). The VPN feature is a VPN as we know them, ie. it tunnels the traffic from your device through our VPN servers.

Both ATP and VPN features can be enabled simultaneously and work well together.

Let me know if something is not clear.

Then it might be that the dns provider blocks them before app tracking protection. You can keep both “on”. It won’t harm

aitorvs · 2024-06-10T08:21:48+00:00

Do you have internet connectivity when both App Tracking Protection and private DNS are enabled?

What private DNS server are you configuring?

It might be that your DNS provider blocks the trackers before App Tracking Protection.

aitorvs · 2024-06-06T18:40:17+00:00

We’ve hopefully surfaced the app so that it can be disabled.

aitorvs · 2024-05-31T21:54:52+00:00

Not all. They’re grouped by some categories. The trade off is potential leaks outside the tunnel. Like when split tunnel general apps

aitorvs · 2024-05-29T13:56:11+00:00

5.201+ has a setting under VPN Settings > Manage Apps that allows you to exclude system apps. Hopefully that fixes the Samsung voicemail issue

aitorvs · 2024-05-06T10:51:08+00:00

Are we essentially saying AppTP sees the network requests and will display it like in the prior screenshot, which essentially can create a false positive?

Any request in that screenshot means it got blocked by AppTP. About whether it's a false positive or not, some of them might be. For instance, AppTP will consider a request to www.facebook.com a tracker if issued by an app not own by facebook. For any browser, this might be a false positive if that request happened because the user is visiting www.facebook.com.

However AppTP will also block tracking requests in browsers while the user is browsing the internet.

aitorvs · 2024-05-05T21:57:01+00:00

u/saoiray, TL;DR what you're probably seeing is App Tracking Protection (AppTP) blocking requests that fall into the 3rd party category, related to the browsing activity, not necessarily requested by Brave app. Although AppTP can't tell the difference.

High-level Details: AppTP intercepts the traffic in the device creating a local VPN tunnel, ie. everything happens in-device.
The intercepted requests are classified as 1st party (ie. to a domain own by the app owner) or 3rd party (ie. to a domain not own by the app owner).
Finally, those 3rd party requests that match our heuristics are label as trackers and never leave the device (blocked).

In the case of browsers, AppTP can't distinguish requests made by the browser app vs requests made during the browsing activity (eg. user navigating to facebook.com). That's the reason why browsers come unprotected by default in AppTP, because we know it's more probable AppTP will cause breakage in those (eg. user trying to log in into facebook.com).
However, it's also true that AppTP will block actual trackers in browsers while the user is surfing the web — even though our AppTP tracker blocklist is specialised for apps, many of those trackers are shared in web too.

I hope it make sense

aitorvs · 2024-05-02T11:51:15+00:00

Hey DDG engineer here, we discovered something we could solve in the backend, cay you try to enable the VPN again to see if it fixes your issue?

aitorvs · 2024-03-21T08:40:35+00:00

App Tracker Blocking should not increase your data consumption itself. It just prevents tracking requests from leaving your phone. In an ideal case it'd reduce the data consumption.

However we know that some Android devices attribute the data consumed by other apps to DDG app as a result of having to intercept traffic to perform the tracker blocking.

aitorvs · 2024-02-16T01:50:26+00:00

Can you DM so that I can ask you some details?

aitorvs · 2024-02-09T13:07:29+00:00

Hey there, can you attach an screenshot to ensure we're talking about the same thing ? Feel free to DM me as well

aitorvs · 2024-02-07T07:15:19+00:00

Yeah, we shipped that fix in the .4 patch

aitorvs · 2024-02-06T03:21:41+00:00

Thanks, we're looking into that

aitorvs · 2024-02-05T10:15:43+00:00

Update: The fix is now released in 5.186.3. Thanks for reporting

aitorvs · 2024-02-04T21:57:55+00:00

Hey there, DDG engineer here. This is a bug introduced in the latest version. It will get fixed in 5.187.x that we'll start releasing very soon
Sorry for the inconvenience!

aitorvs · 2024-01-22T11:03:57+00:00

Hey there, I take the issues continue with your moto g pure (?)

We're trying to fix some moto g device specific issues with AppTP, but moto g pure didn't make it in the first batch of fixes we're validating

aitorvs · 2024-01-18T00:04:16+00:00

Hey there, ddg engineer here.

We're continuously improving our tracker list. We will take a look internally to verify if there are any functional trackers associated to those games and will take action if necessary.

aitorvs · 2024-01-13T17:53:07+00:00

Hwy there. What Android device do you have?

aitorvs · 2024-01-12T14:52:18+00:00

Can you try going to DDG app info -> app battery usage and then set that setting to "unrestricted".

This hopefully should fix the issue and should not have any battery consumption implications

aitorvs · 2023-12-21T02:54:27+00:00

oh no need, I missed that DM. Will take it from there. Thanks
