Signal’s president reveals the cost of running the privacy-preserving platform—not just to drum up donations, but to call out the for-profit surveillance business models it competes against.
The encrypted messaging and calling app Signal has become a one-of-a-kind phenomenon in the tech world: It has grown from the preferred encrypted messenger for the paranoid privacy elite into a legitimately mainstream service with hundreds of millions of installs worldwide. And it has done this entirely as a nonprofit effort, with no venture capital or monetization model, all while holding its own against the best-funded Silicon Valley competitors in the world, like WhatsApp, Facebook Messenger, Gmail, and iMessage.
Today, Signal is revealing something about what it takes to pull that off—and it’s not cheap. For the first time, the Signal Foundation that runs the app has published a full breakdown of Signal’s operating costs: around $40 million this year, projected to hit $50 million by 2025.
Signal’s president, Meredith Whittaker, says her decision to publish the detailed cost numbers in a blog post for the first time—going well beyond the IRS disclosures legally required of nonprofits—was more than just as a frank appeal for year-end donations. By revealing the price of operating a modern communications service, she says, she wanted to call attention to how competitors pay these same expenses: either by profiting directly from monetizing users’ data or, she argues, by locking users into networks that very often operate with that same corporate surveillance business model.
“By being honest about these costs ourselves, we believe that helps provide a view of the engine of the tech industry, the surveillance business model, that is not always apparent to people,” Whittaker tells WIRED. Running a service like Signal—or WhatsApp or Gmail or Telegram—is, she says, “surprisingly expensive. You may not know that, and there’s a good reason you don’t know that, and it’s because it’s not something that companies who pay those expenses via surveillance want you to know.”
Signal pays $14 million a year in infrastructure costs, for instance, including the price of servers, bandwidth, and storage. It uses about 20 petabytes per year of bandwidth, or 20 million gigabytes, to enable voice and video calling alone, which comes to $1.7 million a year. The biggest chunk of those infrastructure costs, fully $6 million annually, goes to telecom firms to pay for the SMS text messages Signal uses to send registration codes to verify new Signal accounts’ phone numbers. That cost has gone up, Signal says, as telecom firms charge more for those text messages in an effort to offset the shrinking use of SMS in favor of cheaper services like Signal and WhatsApp worldwide.
Another $19 million a year or so out of Signal’s budget pays for its staff. Signal now employs about 50 people, a far larger team than a few years ago. In 2016, Signal had just three full-time employees working in a single room in a coworking space in San Francisco. “People didn’t take vacations,” Whittaker says. “People didn’t get on planes because they didn’t want to be offline if there was an outage or something.” While that skeleton-crew era is over—Whittaker says it wasn’t sustainable for those few overworked staffers—she argues that a team of 50 people is still a tiny number compared to services with similar-sized user bases, which often have thousands of employees.

Session, a fork of Signal, is better because as far as privacy goes as you don’t have to download it from a store that violates your privacy. Just go to the offcial site and download the apk.
The biggest benefit is that Session can run completely independant of platform (Google/Apple) push services and will run completely self-contained. You can set Session to check for messages every X minutes. Of course while the app is open and focused, it’s real-time. This removes metadata collection on when/where/how you are messaging.
You can download a self updating apk from Signal’s official website
As far as I know, this version doesn’t have push notifications for microG or google, so it will drain your battery a lot faster because it’s always on. People should just download the Google play version with Aurora Store.
The Aurora Store still uses Google for some pieces, it just provides an anonymized wrapper for them. The Aurora Store developer has an avatar of himself wearing a mask with the following profile info on GitLab.

He’s using Gmail, is that supposed to be ironically funny running all our engagement for his de-Googled product - through Google?
Before I switched to Graphene I ran CalyxOS. It was hacked to pieces and is no where near GrapheneOS or even PostmarketOS I’d say. In fact, I think iOS is probably more secure than CalyxOS!
As well microG has this, anyone step through all that code to verify?
topDomainOf(Uri.parse(appId).host) == "gstatic.com" && rpId == "google.com" -> {
// Valid: Hardcoded support for Google putting their app id under gstatic.com.
// This is gonna save us a ton of requests
true
}
I’ve verified that a straight Session apk install on GrapheneOS does not use Google in any way.
This version detects if you have Google Play Services when you first launch it. If you do, it’ll use it, if not, it moves to websockets.
If you installed GPS after launching Signal, you’ll need to go to in and erase Signal’s app data for it to reset again.
I really only use matrix/element I just was just shocked they’re paying 6 mil a year for phone verification and they aren’t completely underwater
I use element, but for communication with family and friends I use signal. Element app is not as simple, it is a little clunky/buggy and slow. It is not ready for “normal” people.
