Welcome to Phidden! Hide your message in your photo. With this new App you will be able to send your secret messages to your friends and let others believe that you have only sent them a photo! All you have to do is choose your best photo, write your message and Phidden does the rest! It will hide your message within the photo and all you need to do is share ! Whoever receives it will be able to read the message contained only by opening it with Phidden and with no other App or program! ATTENTION The messages hidden in Phidden can only be ‘decoded’ with the same App! For the same reason every photo not ‘encoded’ by Phidden if ‘decoded’ by the same App will return a blank and incomprehensible message! This is not to be considered an error but a non-coded photo! COMPRESSION IS THE ENEMY OF PHIDDEN! ANY FORM OF COMPRESSION WILL COMPROMISE THE HIDDEN MESSAGE! Many file sharing, e-mail client, social network and sharing services usually have a habit of compressing images, so do not entrust them with your encoded photos if you don’t want to lose the hidden message! For the same reason photos should be attached and sent in the original dimensions, as any form of compression will compromise the message and will make it illegible and not decodable! The safest way to maintain the integrity of the secret message is to post the image on Phidden Network ! Other secure methods remain saved in the library, AirDrop, messages or emails (only if sent at maximum resolution). Feel free to make personal tests with the services you usually use to verify if the message remains decodable. NOTE: the use of Phidden, the content of the hidden messages in the photos and their disclosure is to be considered the free choice of the user, the developer cannot be held in any way responsible. Don't forget to leave a review! Your feedback is precious! Thanks for your support ACKNOWLEDGMENTS A warm embrace and particular thanks goes to my friends @Alessio_Vinerbi and @lkaroweb for their help with the code that drives the engine of the App! Heartfelt thanks, guys! Photo and background image by unsplash.com

Stegg hides secret messages and entire photos inside ordinary images. The result looks like a normal picture. Your recipient can reveal what’s hidden in Stegg, and optional password encryption keeps protected secrets unreadable without the password. HOW IT’S DIFFERENT • A photo vault app on your home screen tells anyone holding your phone that you have something to hide. • Your secrets live inside ordinary-looking photos in your normal library. • Calculator Disguise can hide Stegg itself behind a working calculator. • Hiding a photo creates a new carrier image. Your original stays in your library until you delete it. PRIVATE BY DESIGN • Every message and image is processed entirely on your device. • Stegg never uploads your images, messages, or passwords. • No account, usage tracking, or third-party ads. • Password protection uses strong encryption; the correct password is required to decrypt the secret. HIDE, SHARE, AND REVEAL • Hide text inside a photo without visibly changing it. • Hide a complete photo inside another with Stegg Pro. • Share compatible Steggs with other Stegg users. • Open images from other apps directly in Reveal. • Share only the stegged image with Discreet Share, or send a short explanation with Invite to Decode. • Core message hiding and revealing stay free so recipients never need Pro to decode what you send. BUILT FOR REAL-WORLD SHARING • Social-Proof mode helps preserve hidden data when a service may recompress an image. • Deep Search looks for hidden data in many cropped, resized, or screenshot images. • For the most reliable results, send or download the original image file. STEGG PRO: ONE PURCHASE Unlock photo-in-photo hiding, Calculator Disguise, five custom themes, and matching app icons. Pay once. No subscription. Your localized price appears before you buy.
