Google Maps is incredibly useful — and yes, it also collects location data (with user controls).

Privacy-minded teams and individuals are exploring tools built on OpenStreetMap, like OsmAnd and Organic Maps.
They offer offline navigation, no ads, and no built-in location profiling.

The tradeoff? Less commercial data and reviews.
For some use cases, that’s a feature, not a bug.

Google brings Maps data to Gemini API developers

https://web.brid.gy/r/https://nerds.xyz/2025/10/google-maps-gemini-api-grounding/

"Operating from their base in Jakarta, where permissive export laws have allowed their surveillance business to flourish, First Wap’s European founders and executives have quietly built a phone-tracking empire, with a footprint extending from the Vatican to the Middle East to Silicon Valley.

It calls its proprietary system Altamides, which it describes in promotional materials as “a unified platform to covertly locate the whereabouts of single or multiple suspects in real-time, to detect movement patterns, and to detect whether suspects are in close vicinity with each other.”

Altamides leaves no trace on the phones it targets, unlike spyware such as Pegasus. Nor does it require a target to click on a malicious link or show any of the telltale signs (such as overheating or a short battery life) of remote monitoring.

Its secret is shrewd use of the antiquated telecom language Signaling System No. 7, known as SS7, that phone carriers use to route calls and text messages. Any entity with SS7 access can send queries requesting information about which cell tower a phone subscriber is nearest to, an essential first step to sending a text message or making a call to that subscriber. But First Wap’s technology uses SS7 to zero in on phone numbers and trace the location of their users.

First Wap emphasizes that its technology is used by law enforcement to “fight against organized crime, terrorism and corruption.” It sells Altamides directly, as well as through third-party resellers."

2. Streetcomplete and #Openstreetmaps

On the topic of #geolocation , there's another FOSS project that relies on community submissions to build a privacy preserving map

let's face it, Google Maps is the most solid, polished and convenient maps app out there, it offers detailed business listings, phone numbers, open hours, photos and reviews, Streetview (which OSM lacks), live traffic, routing algorithms with turn by turn navigation.. Etc.

But as it's the case with proprietary software, convenience comes at a cost, a cost that no one can afford, loss of privacy.

Most people fail to recognize how sensitive location data is, how it's used against them and how it can be abused in the future.

if I ask.. where were you on February 9, 2012, at 3 o'clock? you have no clue, you can't even remember what you had for dinner last night! me too :-) our brains can't recall events with time and location with such great precision, if you can.. you must be Charles Xavier from X-Men :-P

But you know who can remember? Google. the Ad company profiles individuals by tracking queries, routes, and interactions, it records your movements by a feature called location history which is turned on by default, even when you don't use the app, your movements are still logged, heck.. even if you turn off location history altogether, Google keeps on tracking you.. this should tell you how much valuable location data is for E-Corp, where you work or study, what you're planning to buy, where you go for entrainment.. etc. all used to create a profile so that the surveillance machine can target you with ads..

The brightside is that we don't have to use a surveillance tool like Google Maps, OrganicMaps is a free and open source software that respects your privacy, does not collect or transmit your location, search history, or usage data and it encourages you to use it offline by letting you know that you have to download maps for your area.

Organic Maps uses OpenStreeMaps which is also free software, but as I mentioned it's not as rich as Google Maps in terms of data. :-(

Which brings us to Streetcomplete, a FOSS android app designed to make contributing to OpenStreetMap easy. It's really like a real life game and I find it fun, It uses a simple question and answer interface to gather missing OpenStreeMaps details like: surface types of paths, opening hours of shops, speed limits.. etc

Submitted data will appear on OpenStreeMaps, so all users of apps like @organicmaps and @CoMaps can benefit from :-)

You can contribute to the #freesoftware movement even if you don't know how to write #code here's some practical examples:

1. @beacondb & #Neostumbler

BeaconDB is community-driven wireless geolocation database that serves as a replacement for Mozilla Location Services (MLS), which was discontinued in March 2024.

why is this project important?

because #Google collects extensive location data tied to user accounts for advertising and profiling (even if you turn off location history) Google doesn't understand consent, what a surprise! 

BeaconDB will provide privacy friendly geolocation, allowing #degoogled #android ROMs like #CalyxOS and #GrapheneOS to be used without relying on Google (Google's location services)

Neostumbler is an #opensource android app, that collects geolocation data from wireless signals such as Wi-Fi access points, cell towers, and Bluetooth beacons, NS does not collect personal identifying information, only anonymized wireless signal data and it can be turned off at any time. (can't say the same for Google)

you can start contributing to BeaconDB simply by downloading and installing NeoStumbler, enabling GPS, open NS and start a scan, start walking or driving, and after you cross a certain distance, you'll see some generated reports, press upload to upload them all (you can also go to settings and enable automatic uploading in the background)

If you want to volunteer and help us free our phones, laptops and smart watches from corporate ecosystems (like Google's location services) and achieve digital sovereignty in the aspect of geolocation, take a look at these links
