GizliAlan: Vault+Second Phone

Keep work and personal life apart on the phone you already own. GizliAlan gives you a second phone, a private encrypted vault that opens from a working calculator, and Joi: the AI living in your second phone.

SECOND PHONE – WITHOUT BUYING ONE
• Separate work and personal apps on one device, using Android's built-in work profile
• Its own apps and accounts – for example, a separate WhatsApp

PRIVATE VAULT BEHIND A CALCULATOR
• The app appears as "Calculator" and really works; type your PIN and press "=" to open the vault (can be turned off in Settings)
• Photos, videos, notes and files encrypted with AES-256-GCM, stored only on your device
• No account needed; vault content never reaches our servers
• Private in-vault browser; downloads go straight to the vault
• Decoy PIN that opens a separate, harmless space
• PIN plus optional fingerprint or face unlock, auto-lock
• Screenshots and recent-apps previews are blocked

JOI – THE AI LIVING IN YOUR SECOND PHONE
• Chat: questions, ideas, plans
• Writes notes for you and saves them encrypted in your vault (Pro)
• Searches and summarizes your notes on the device (Pro)
• Voice chat and saved, encrypted chat history (Pro)
• Free: 10 messages a day. Pro: unlimited
• Every answer has a Report button. Joi is an AI and can make mistakes
Online answers are generated with Google Gemini only after you agree. Only what you type to Joi is sent; your notes, photos and files never are.

SPEAKS YOUR LANGUAGE
Opens in your phone's language: English, Turkish, French, German, Chinese, Spanish, Italian, Dutch and Russian.

WHAT IT IS NOT
