Hmm...So I have Telegram installed via F-Droid (so presumably without Google Play Services). I do NOT have the "People Nearby" feature. I am curious if that means my location is not published?
Edit: I turned enabled location sharing under iOS settings for Telegram app and "Find People Nearby" is now showing as the first list item under the Contacts tab.
More systems need to truncate location data. It is relatively "easy" to solve this particular issue by just not returning highly specific data. Instead of saying "896m", return " You can also truncate the data you have on users. 2 digits of Decimal_degrees precision is +/- 1KM. If you're doing an Uber-like service, knowing where a user is down to a few feet makes a different (which side of the street). But if you're…
This could probably be automated to track in real-time someone's position.
I used the "people nearby" feature once, and I kept getting random messages from random people 2 months later. I could not figure out how the hell to turn it off.

Map cells are the best solution available for 90% of locations, but they don't help with the 10% that's close to map borders. If an user randomly jumps between two map cells you know they live at the boundary. Generally there is often noise in GPS signals so it's likely that person will jump around. Furthermore, if a person uses multiple services, and each service has its own cell layout, you can check all services a…
Maybe overlapping regions would be a fix?
It's a shame that people still use Telegram when Signal is so much better, and has better credentials all around.

Signal is terrible. I use the app still, but it’s horribly buggy. The disappearing messages, a hallmark feature, is fundamentally broken in some way that I can’t fully comprehend. Totally unreliable. Telegram is better in every way... except security.
> Telegram is better in every way... except security. Which is why anyone bothers with these type apps in the first place, I'd like to say I'm dissapointed with the sentiment towards Signal, especially given how many here work in tech and understand how leaky these apps are designed to be and how hard development can be with a bare bones team (I experienced this first hand), but it never fails to bank on the notion t…

Thats all I need to know to make a choice given the track record of the robotic buffoon class that believe everything that momentarily scales up needs to be monetized asap to shit out one mindless billionaire here and there.
So in the article, the author was able to find the x- and y- coordinates of the other user. What if the target user lives in a high rise building, is there any technique you can get the height of the said user? Makes me wonder how the law enforcement is able to tri-angulate the suspect's exact location.
My somewhat educated guess would be that, firstly, cell tower triangulation includes altitude by necessity of measuring directly the reach of electromagnetic waves, whereas Telegram advertises the subset of users' GPS data that they choose to advertise, which is likely just lat-long. Secondly, law enforcement also likely has the cooperation of the administration of said high-rise building.
