Calculator Pro+ looks and works like a normal calculator. Enter your

secret PIN on the keypad and unlock a completely hidden world — private

SMS, in-app calls, chats and media, invisible to everyone else.

🧮 𝗛𝗜𝗗𝗗𝗘𝗡 𝗜𝗡𝗦𝗜𝗗𝗘 𝗔 𝗥𝗘𝗔𝗟 𝗖𝗔𝗟𝗖𝗨𝗟𝗔𝗧𝗢𝗥

Dial your secret PIN on the keypad to open your private vault — no

swipes, no obvious unlock screens. On Android 9 and below, hide the

app icon completely and access it via a secret browser link. On

Android 10 and above, the app stays visible as a normal calculator.

🔒 𝗠𝗨𝗟𝗧𝗜-𝗟𝗔𝗬𝗘𝗥 𝗦𝗘𝗖𝗨𝗥𝗜𝗧𝗬

• PIN lock & fingerprint unlock

• Fake PIN — decoy shows empty inbox to anyone who asks

• Auto-lock on screen off or idle timer

• Shake-to-close for instant privacy in public

💬 𝗣𝗥𝗜𝗩𝗔𝗧𝗘 𝗠𝗘𝗦𝗦𝗔𝗚𝗜𝗡𝗚 — 𝗧𝗪𝗢 𝗪𝗔𝗬𝗦

── Hide Native SMS & MMS (via free AdvanceSMS app) ──

Set AdvanceSMS as your default SMS app — it silently routes private

contacts' messages into Calculator Pro+'s vault. Never visible in

your phone's native inbox. Replies sent as normal SMS with no

indication you are using a hidden app.

── Free App-to-App Messaging ──

When both sides use Calculator Pro+, messages travel over the app's

own private network — no SMS, no carrier charges, no device traces.

Free over Wi-Fi or mobile data.

• Smart reply suggestions

• Disappearing messages — 1 hour to 3 months

• Delete for Everyone — both sides, instantly
