SHARE SECRETS WITH STEALTH AND STYLE
The Internet is riddled with watchful eyes. Which is why we built this very site — to provide a venue for upstanding citizens like yourself to share privileged information with one another. Just type in a secret, and our site will stash it between the pixels of glitchy photo filters indecipherable to all but your intended recipients.
It’s sneaky. It’s stealthy. It’s Cryptstagram.
