## Description

cal-cool is a private, secure messenger hidden behind a fully working calculator.

Open the app and you see a real calculator. Enter your secret PIN and press "=" — and your private messenger unlocks: encrypted chats, voice and video calls, disappearing messages and a set of everyday tools.

WHY CAL-COOL
• Honest privacy: end-to-end encrypted chats and calls
• Calculator disguise: your conversations stay invisible to prying eyes
• Panic PIN: a second PIN instantly opens a clean, empty profile
• Disappearing messages, screenshot protection, encrypted media
• Voice & video calls with VoIP push — battery friendly
• Offline P2P chat: exchange messages nearby via local network without internet
• Tools: notes, planner, weather, offline maps, voice notebook and more
• 3 languages: English, Russian, Arabic

SECURITY FIRST
Messages are encrypted in transit and at rest. We do not sell data, we do not show ads, we do not track you. Local data is protected with AES-GCM; the app locks itself behind the calculator whenever you leave it.

Note: the calculator really works — it is a fully functional calculator app AND a full-featured private messenger in one.
