SD Contacts vs ThreatScoopOnionChat
Side-by-side comparison of two open source alternatives
SD Contacts
This app is meant for users that don't want to synchronize their contacts online, but want to keep them local to the phone. Though there is a problem, if you brick your phone, you might lose all your contacts. With this app, you will have a backup of your contacts stored on the SD card. You can take it out and import the contacts into your new phone.
ThreatScoopOnionChat
# ThreadScoopOnionChat This version is a fork from " https://github.com/session-foundation/session-android ", enfocado en la privacidad. ## How Did ThreadScoopOnionChat Come About? I have always been a fan of privacy and security in communications, and I am constantly researching potential security breaches in messaging applications. ThreadScoopOnionChat emerged after the analysis of this blog "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/", in which several aspects are described as to why using Session is not recommended, and I wondered how it is possible that a foundation focused on privacy—with the grants and support it receives—has not been able to improve this protocol. I still do not understand the answer, since my resources are much smaller than those of a foundation compared to that of a person who is simply a fan of privacy and security. In this blog, certain problems were described: 1> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#insufficient-entropy-ed25519" 2> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#in-band-negotiation" 3> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#public-keys-aes-gcm" This is a forked version privacy focussed from Session.
