StegoSafe

StegoSafe hides an encrypted secret inside an ordinary photo. The photo still looks like a photo — the secret rides in bits the eye can't see — so what you protect doesn't announce itself.

Everything happens on your device. No account, no sign-in, no servers. Your secret and your password never leave your iPhone, iPad, or Mac.

HOW IT WORKS
• Type a secret — a recovery phrase, a password, a private note.
• Pick a cover photo and choose how to protect it.
• StegoSafe encrypts the secret and weaves it into the image.
• Save the PNG, share it, or keep it. To read it back, open it in StegoSafe with your credentials.

THREE WAYS TO PROTECT
• Password — open it on any device, any time, as long as you know the password.
• This device only — a key kept on this device behind Face ID / Touch ID. Nothing to phish out of you; nothing to recover if the device is lost.
• Face ID / Touch ID + PIN — two factors. Opening needs both the device and a PIN you set.

SPLIT ACROSS PHOTOS
Break a secret into several share-images and set how many are needed to rebuild it — for example, any 3 of 5. No single photo reveals anything on its own.

BUILT FOR PRIVACY
• AES-256-GCM encryption, keys derived with PBKDF2-SHA256 (600,000 iterations).
• Keep it as a PNG — re-compressing it (as chat apps do) is what destroys the hidden data, so StegoSafe helps you keep the real file.
• Nothing is read from an image until you unlock it. A damaged or re-compressed image is reported as damaged — you're never handed a secret that's subtly wrong.

IMPORTANT
Only you can open your content. If you lose your password — or, for device-bound images, the device — it cannot be recovered, by you or by us. Write your password down somewhere safe.

StegoSafe is for lawful, personal use.
