Now Apps Can Track You Even After You Uninstall Them (bloomberg.com) 118
If it seems as though the app you deleted last week is suddenly popping up everywhere, it may not be mere coincidence. From a report: Companies that cater to app makers have found ways to game both iOS and Android, enabling them to figure out which users have uninstalled a given piece of software lately -- and making it easy to pelt the departed with ads aimed at winning them back. Adjust, AppsFlyer, MoEngage, Localytics, and CleverTap are among the companies that offer uninstall trackers, usually as part of a broader set of developer tools. Their customers include T-Mobile US, Spotify Technology, and Yelp. Critics say they're a fresh reason to reassess online privacy rights and limit what companies can do with user data. "Most tech companies are not giving people nuanced privacy choices, if they give them choices at all," says Jeremy Gillula, tech policy director at the Electronic Frontier Foundation, a privacy advocate.
Some providers say these tracking tools are meant to measure user reaction to app updates and other changes. Jude McColgan, chief executive officer of Boston's Localytics, says he hasn't seen clients use the technology to target former users with ads. Ehren Maedge, vice president for marketing and sales at MoEngage Inc. in San Francisco, says it's up to the app makers not to do so. "The dialogue is between our customers and their end users," he says. "If they violate users' trust, it's not going to go well for them." Adjust, AppsFlyer, and CleverTap didn't respond to requests for comment, nor did T-Mobile, Spotify, or Yelp.
Uninstall tracking exploits a core element of Apple's and Google's mobile operating systems: push notifications. Developers have always been able to use so-called silent push notifications to ping installed apps at regular intervals without alerting the user -- to refresh an inbox or social media feed while the app is running in the background, for example. But if the app doesn't ping the developer back, the app is logged as uninstalled, and the uninstall tracking tools add those changes to the file associated with the given mobile device's unique advertising ID, details that make it easy to identify just who's holding the phone and advertise the app to them wherever they go.

You don't get to choose the push notification permission. It's how background apps work. It's how messaging apps get notified of new messages, etc.
For example, I have Pushover installed on my phone. Under App Info/Permissions, it has no explicit permissions granted. It has background notifications as part of the "receive data from internet" permission that requires no user acceptance.
The lack of response from these notifications is what triggers the flag that you've uninstalled it. Aeroplane mode won't stop

You've got it backwards. When you install the app it asks for permissions to access this that and the other. Most times if you say "no" the app doesn't work. If you say yes the app phones home and the server knows you've installed the app.
Now every so often the server uses push notifications to query the app. If it gets no response it assumes you've uninstalled it, since it won't work anyway if you block notifications and data access.
So yes you have controlled over whether you install the app or not. If you

Silent push notifications can have any payload the app programmer needs to send. Any silent push notification campaign will result in the feedback service updating the list of invalid devices. They can't send a ping to your device, they need to go through apple APNS service to contact the device, which will cause the aforementioned feedback service to update the list. The same process happens with Android.

Also, I guess that you could send a payload to trigger an app awake signal and ping back to the server, but that would use more of the device battery and processing time, and on android at least it would show that the app is using background process and the user would be presented with an option to turn that off. It`s better to only rely on the feedback mecanism not to cause those issues.

They can target your device through mobile ad networks since they have the device advertising unique ID. So you uninstall the app and suddenly you start seeing ads for it in other ad-supported apps and possibly when you browse from the phone.

That advertising ID, at least on iOS, is specific to that application only... trying to send messages to that ID after you've uninstalled it wouldn't do anything.
Even if you reinstalled the application, you would get an entirely new unique advertising ID associated with the app.
Unless you choose to send other personal identifying information to the publisher, they don't have any way to send you messages about anything if you either disable push notifications from the app or simply uninstall it.
The only thing the publisher will know is that the unique ID associated with a particular purchase is not working.
