A private place for future you

A quiet place to write, wait, and return.
Inside Haku
A little space for what comes next.
Every screen is designed to keep the feeling of a letter intact: personal, unhurried, and yours.
WriteShape the thought before you send it. 
HorizonSee what you have sent across time. 
ArriveA quiet moment, held until its time. 
ReturnMeet the person you were becoming.
Independent by choice
Made by one person.
I made Haku for myself because the alternatives no longer felt right, and I share it in case it helps you too.
Haku is and always will be free. I earn nothing from keeping it available: there are no ads, subscriptions, or paid upgrades.
Free forever.
Plainly stated
Privacy without theater.
Haku handles personal writing, so its legal pages explain the real system: what stays on your device, what Apple services receive, and how to delete or export your data.
