👋 I’m the developer of HiddenLetter.
The idea is simple: some messages deserve more than a place in your chat history.
HiddenLetter lets you encrypt and hide messages, photos, audio, videos, and files inside ordinary images. You can add password, time, or location locks—or leave a secret on the map for someone to discover.
Think surprise letters, personal keepsakes, or a little treasure hunt in the real world.
I’d love to hear your thoughts: would you use it more for private keepsakes or location-based surprises?
Thanks for taking a look! Happy to answer questions and hear what could be better.
