A private diary for two
One blind question a day, growing into a lasting, end-to-end encrypted conversation. No algorithms. No audience.

Today's question
“What was your favorite moment from our last trip?”
You each answer separately, blind to the other's reply. Once both are in, the answers unlock to each other at the same moment - and become a conversation of their own. Five questions a day, a story that keeps growing.

Moments

Same city. Same quiet. Same two.

Some things don't need to be said.

One more line of the story, every night.
The moment that makes it work
“What do you find most beautiful about the life we're building?”
You
That we never stopped being curious about each other. Even on ordinary days.
Them
How safe it feels. I can say anything here and it stays ours.
You answer blind. Both answers lock - then unlock to each other at the same moment.
Features
The server never sees the content of your messages - only the two of you do.
No endless scroll. Five meaningful questions, answered blind, that open real conversations.
Every photo and video is compressed and end-to-end encrypted before it ever leaves your phone.
Choose from default scenes or add your own photo - always readable under a soft overlay.
Once given, an answer can never be edited or deleted - immutable at the database level.
Your account is created in your device's language, changeable anytime from Profile.
“Built to stay two - never a third, whether that's an algorithm or an audience.”
