Hide secrets in plain photos & lock your vault. 100% offline & free.

Hilia hides your secrets in plain sight. Text, files, or photos vanish inside an ordinary-looking picture — real steganography, not just a locked folder. 100% offline. No account needed. Your data never leaves your phone. WHAT YOU CAN DO • Hide secret text, a document, or a photo inside any cover photo — invisible to anyone but you • Reveal hidden secrets instantly from any stego image you receive • Store everything in a private, encrypted on-device vault • Scatter hidden photos into your regular gallery instead of a separate album, so they blend in as just another photo STEGANOGRAPHY — HIDING IN PLAIN SIGHT Encryption protects your data but leaves obvious traces; steganography hides the very fact that a secret exists. Hilia weaves your data directly into a photo's pixels, choosing the best-quality method for full detail or an extra-stealth method that keeps a camera photo exactly as it is. The result opens and looks like any normal photo — because it is one. PRIVACY BY DESIGN • Fully offline — hide and reveal without an account or sign-up • Nothing is uploaded — we don't collect or see your data • Revealed secrets auto-blank the moment you switch apps, banking-app style • Optional passcode plus strong encryption layered on top of the hiding itself DECOY VAULT — YOUR SAFETY NET If someone ever forces you to unlock your phone, you shouldn't have to hand over your real secrets. Set up a second, decoy vault with its own passcode — it looks and behaves exactly like your real vault, but only shows what you choose to keep in it. Open the decoy passcode and that's all anyone sees; your real vault stays hidden and untouched. • Two vaults, two passcodes — the decoy is indistinguishable from the real one until you decide otherwise • Built for real-world situations: border checks, a stolen or seized phone, or anyone pressuring you to unlock FREE FOR EVERYONE • Hilia's full hide-and-reveal experience is free, with no account and no paywall • Free use is supported by ads; an optional Gold membership removes ads and adds extra perks WHO USES HILIA • Anyone who wants to keep something truly private, on their own device • People passing sensitive information discreetly • Privacy-conscious users avoiding cloud photo scanning of what they hide • Or just for fun — send a friend a photo and see if they can spot the secret inside GET STARTED Download Hilia and hide your first secret in under a minute — no account, no cloud, no catch. GOOD TO KNOW • Look for the app named "Hilia" on your device • Share the original file — chat apps that recompress or resize images can destroy hidden data • Vault data is removed if you uninstall the app • Hilia is a privacy tool: please use it responsibly and lawfully
