ThreatScoopOnionChat
APK
# 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.

Thumb-Key
APK
Thumb-Key is a privacy-conscious smart keyboard, made specifically for your thumbs. It features a 3x3 grid layout, and uses swipes for the less common letters. Its easy to learn, and designed for fast typing speeds. Instead of relying on profit-driven, privacy-offending word and sentence prediction for accuracy, as do most popular phone keyboards like Gboard and Swiftkey, Thumb-Key uses large keys with predictable positions, to prevent your eyes from hunting and pecking for letters. As the key positions get ingrained into your muscle memory, eventually you'll be able to appromixate the fast speeds of touch-typing, your eyes never having to leave the text edit area. This project is a follow-up to the now unmaintained (and closed-source) MessagEase Keyboard, which is its main inspiration.
