Secret Delivery encrypts your files and text so only the people you choose can read them. No accounts. No servers. No tracking. Your password never leaves your device — and neither does your data.
FREE TO START
• Encrypt and decrypt text messages — free, forever.
• Share encrypted text as a secretdelivery:// link, or copy and paste the ciphertext anywhere.
PRO UNLOCK (one-time purchase)
• Encrypt and decrypt files of any type.
• Quick Look previews of .sdenc files right inside Files and Finder.
• Import from Camera and Photos, and save to iCloud Drive.
• Face ID / Touch ID lock and configurable autolock.
• Run encrypt and decrypt from Shortcuts, Siri, and Spotlight — or with a long-press in Files.
STRONGER ENCRYPTION
• New files use AES-256-GCM with PBKDF2-HMAC-SHA256 key strengthening (600,000 iterations), a random salt and nonce per file, and an authentication tag that detects tampering.
• Your existing encrypted files still open — Secret Delivery detects the format automatically. Need to send a file to someone on an older version? Turn on Legacy Mode for the session, or upgrade old files in place.
PRIVATE BY DESIGN
• Everything happens on-device. We collect nothing, and there is no analytics SDK.
• The app blurs its contents in the app switcher and wipes temporary decrypted files when it moves to the background.

This app is fantastic, it's exactly what I needed to send documents to my coworkers without fear of them being read by unwanted eyes.The new iOS 8 Extension for previewing pictures and documents that are sent to you is amazing as well, it make it so much quicker to not have to leave the messages app to view an encrypted picture someone texted you.
Why didn't I use it before?

That's a very cool idea for protecting messages and files. I personally don't want any of my messages or pictures that I send to be seen by other people. It's even better than a snapchat because without a password it's impossible to open the message/file. Love it!
Great app!

Really cool if only more people had it we could use it more
