The worst part is there isn't any possible way I know of to defend yourself against this other than not having a phone.

I'm hoping the Librem 5 succeeds. I think disabling the baseband would be a solve and at least slightly more trustworthy than airplane mode.

Right now I think you're right, there's no defending against it without turning off devices.

*wary

Or leery

Interesting. I wonder if the mistaken use of "weary" comes from a combination of "wary" and "leery"! I always assumed it was because "wear" is pronounced the same as the first syllable of "wary". Unfortunately "weary" is already a word and "I'm wary of X" has a different meaning from "I'm weary of X", but similar enough that a lot of confusion could result.

>Qualcomm IZat location services did a quick check, it's not on my phone (SD 820 SoC). >other location-based trustzone applets remain running even on custom ROMs. I have no doubt some proprietary blobs still remain on custom ROMs, but do those actually send back location data to the OEM?

You have a Qualcomm Snapdragon 820? Oh yes, IZat is definitively there, along with other interesting trustzone applets :) It is running under QSEE (Qualcomm) and/or MobiCore (Trustonic) OS, which is separate from your Android OS. It is left untouched by custom ROMs.

Are you sure? According to https://forum.xda-developers.com/android/software-hacking/ar..., they have corresponding apps running in the main OS as well.

> the Electronic Communications Privacy Act only restricts telecom companies from disclosing data to the government. It doesn't restrict disclosure to other companies Clearly the US has their priorities completely the wrong way.

To corporations, you have no inalienable rights. They're just more things to be bought and sold.

The problem is once it's at the cell carrier level it doesn't even matter if you use a dumb phone. They know roughly where you are based on tower triangulation.

As an amateur radio operator, I would expect nothing less for carrying a highly networked radio transceiver with loads of sensors including geopositioning. Simply put: don't want to be tracked? Put your phone in a lead sealed box or leave it at home. Tracking only tracks the phone , not your person.

Even simpler: don't want to be tracked? Don't have a mobile phone.

And how can I buy this realtime data? Also > Hedge funds or services who analyze it for hedge funds is the big one. It's normal to track hundreds of millions of people a day and trade stocks based on where they go. Any articles/webpages about this one? Or a company name who is doing it?

Pinsight is a big one. But there are too many to name. In 2018, you should assume that any free service (Unroll.me), web/mobile SDK (Slice), email client (Airmail), personal finance tracker (Mint), integration API (Plaid), geolocator (Foursquare), etc is monetized by selling your data en masse for market research. It's not just location data. Dig into the TOS of free services you use. It's your receipts, your transac…

Assuming you’re talking about Airmail, the iOS and Mac mail client[1] (which is not a free app), do you have any reference to back up this claim? Their privacy statement states:

> Airmail does not share your information with any third parties. We are not in the business of selling your data. However, we may disclose information if we determine that such disclosure is reasonably necessary to comply with the law.

They also state that they do not send information to their servers unless you enable push notifications, store data only for this purpose, and delete the data when you disable this setting.

For those who want to try out LocationSmart, you can use it here: https://www.locationsmart.com/try/ They were about two blocks off, and located me by cell tower. Apparently they don't have (or at least don't admit to having) A-GPS level data for me.

I'm somewhat weary. This might be the final missing piece to connect your mobile phone number to your mobile browser user agent, or even worse, your desktop browser agent.

If the mobile carriers are selling your real time location data, I don't think there is much stopping them from also selling your browser user agents.

Any company that sells you access to ad real-time bidding. You connect to a event fire-hose that gives you a nice standardized json for each ad target, with plenty of data about the user (including geolocation), and you choose whether to bid or not on each ad, in realtime. It is an open standard: https://www.iab.com/guidelines/real-time-bidding-rtb-project...

Do you get that data before you place the bid? Can you can just bid the minimum amount so you never actually buy an ad, but get the tracking data anyway?

Throwaway account. I work in location / mapping / geo. Some of us have been waiting for this to blow (which it hasn't yet). The public has zero idea how much personal location data is available. It's not just your cell carrier. Your cell phone chip manufacturer, GPS chip manufacturer, phone manufacturer and then pretty much anyone on the installed OS (android crapware) is getting a copy of your location data. Usually…

How can one prevent this and still carry a cell phone? Would keeping one's phone in a faraday bag defeat this constant tracking?

Switch to flight mode.

So basically either give up your right for privacy or don't use any new technology? That doesn't look practical. A better idea would be to ban cell carriers (and anyone else) from using location data for anything except explicitly permitted by law, like help in emergencies or conducting investigations.

That doesn't do anything to protect your data from being accessed by the State, which is actually the bigger problem.
