iPhone
Send a photo everyone can see. Hide a message only your person can read.
GhostCode hides a real, encrypted message inside an ordinary photo. Write up to 4,000 characters, pick any picture, and set a Key. You get back a photo that looks completely normal. Text it, post it, share it anywhere. Only someone with GhostCode and your Key can open what is inside.
One image. Two audiences. You decide who gets the real meaning.
WHAT PEOPLE USE IT FOR
• A love note hidden inside the photo you send every morning
• A scavenger hunt clue only the birthday person can unlock
• A members-only drop for your fans behind one ordinary picture
• The wifi password for your houseguests, inside the welcome photo
• A whole letter, not a one-liner: up to 4,000 characters per photo
HOW IT WORKS
1. Write your message and pick a photo (or a QR code)
2. Set a Key, a passphrase only you and your people know
3. Share the photo anywhere, like any other photo
4. They open it in GhostCode, enter the Key, and unlock the real message
MORE THAN PHOTOS
• Pixel Ghosting: on-device AI bonds your encrypted message to the picture, and the photo looks identical to the naked eye
• QR mode: pack your message into a QR code that scans on any phone
• Decoy Link (QR): one code, two destinations. Everyone gets a public page, people with the Key get the real one
• Failsafe: a decoy Key reveals an alternate message
• Self-destruct: a reveal stops working after the window you choose
PRIVATE BY DESIGN
• No account, no sign-up, no login
• Your readable message and your Key never leave your device
• Strong, standard encryption (AES-256-GCM with passphrase hardening)
• Sensitive screens are protected, and data deletion is honored in-app
GHOST MODE (optional upgrade)
GhostCode is free to use, with some limits. Ghost Mode unlocks unlimited protected creates, unlimited saved Keys, Decoy Link, extended self-destruct timers, and Failsafe filters. Ghost Mode is a subscription billed weekly or yearly (with a free trial on the weekly plan). It renews automatically unless cancelled, and you can manage or cancel anytime from your store account. Full terms are shown on the purchase screen.
A NOTE ON HOW IT STAYS SECURE
Revealing a protected message needs a one-time check with GhostCode's verification service, which stops brute-force guessing and lets messages self-destruct or be revoked. GhostCode never sees your Key or your readable message. For photo (Pixel Ghosting) messages, your encrypted message is stored on GhostCode's servers for the message's lifetime, so it can be revealed and auto-deleted; it stays encrypted and cannot be read without your Key. It is deleted at self-destruct or expiry, or right away when you request data deletion.
