Most cybersecurity and antivirus apps today behave exactly like the spyware they claim to fight — uploading your installed apps, contacts, browser history, and scanned URLs to remote servers for data mining and ad targeting.
SafeSignal is built on an uncompromising privacy philosophy:
PackageManager APIs, hardware keystore cryptography, and local offline signatures..env files, no paid API keys (VirusTotal, Supabase, or OpenAI), and no rate limits. Clone, compile, and run.---
