- Requires a phone number
- Depends on Big Tech's servers
- Got founded by the US government
- Seems to absolutely love Big Tech because they hide the APK download page quite well[1]
- It's centralized
I use my own Snikket server to communicate with people using OMEMO (Signal Protocol). No phone number requirements, no centralized server, no Big Tech, just you and the people you write with, with your privacy fully intact. Just like in the good old days (as it should be to this days, greedy f*****s).
[1]: signal.org/download > Android redirects you to Google Play Store. signal.org/download/android > Download for Android redirects you to Google Play Store. signal.org/install redirects you to Google Play Store. You'll search "forever" to find the "download APK file" link until you give up and using a search engine: "signal apk".
Not until then you'll find signal.org/android/apk. And when you visit that page, a link to Google Play Store is listed on top, and below it, in the "danger zone", you'll find the APK download button. Yes, exactly, the Signal team wants you to be on the "safe zone" by downloading the app through Google Play Store.
"focus on privacy" my ass. Close to forcing someone to use Big Tech shitty stuff is NOT focus on privacy.
Sorry, rant is over. Now breakfast time.
The chat history is there until you change client/device and got a new set of keys. New encryption keys can't decrypt messages and files sent with a previous keys.
Snikket is FOSS, so yes, it's free when self-hosting :)
