Good news. Cell-site simulators are used to spy on all cell phones. In the 4th circuit, they now require a warrant to use.

Good news. Makes it possible for you to delete the signal app and reinstall it (when crossing a border or doing higher risk activism) and just save your recovery key somewhere very safe.

So the only way the gov't can discover that you are the person behind the signal account is by seizing your phone. Also, it just makes it easier to have data-only burner phones that doesn't have a phone number associated. Lastly - you could get a Google Play gift card at the store and use that.
023
ActivistChecklist.org @activistchecklist.org · 19/09/2026
Yep. So the following things could be revealed through gov't subpoena: 1) ✅ That you spend $3 on Signal (which implies you get a Signal Login) 2) ✅ The identity on your credit card is connected to your app store account But the specific signal account is still disconnected from the payment.
120
ActivistChecklist.org @activistchecklist.org · 18/09/2026
Clarification: The $3 goes through the app store. Signal has a "zero knowledge" system for payments, which means that DO NOT keep any record of the transaction connected to your account. So you can remain anonymous.
140
ActivistChecklist.org @activistchecklist.org · 18/09/2026
Ah yeah I should have clarified in the original post: Signal already has a "zero knowledge" system where they keep no information about your payment in their systems. So there is no chain of connection between the payment being made and your account.

Big news! Signal is introducing "Signal Login" which lets you register without a phone number. It costs $3 (one-time fee) to help prevent spam/abuse on their system. This is great for added privacy! And for folks who want to create extra burner accounts.

Fun fact: We're often told that password strength is the most important thing. But password *uniqueness* is actually a better defense. Why? Because if one site you use gets breached, that password won't get a hacker into your other accounts. (Strength+uniqueness is best, of course!)

A police term to know: "Parallel construction" This is when they obtain information about your activities in a way that would NOT stand up in court (warrantless surveillance). Using what they obtained illegally, they then re-create a chain of evidence in a way that WOULD stand up in court.
