Harukan - One Box a Day

One box a day.
You don't have to write well. "Tired." is a fine place to start.

■ There is no server
Harukan has no sign-up, no login, and no developer-operated server.
What you write and the photos you attach never leave this device.
The developer cannot read them either.

■ Three easy ways to write
· Free — as much or as little as you like
· One line — a single sentence
· Prompt — answer today's question

■ Passcode and fingerprint lock
Set a passcode and your titles, entries, tags and photos are encrypted on the device.
The key is your passcode itself, so no one — including the developer — can open it.
Unlock with your fingerprint too.

■ Discover your own rhythm
· Mood over time and day-of-week patterns
· The words you use most
· Correlations like "how I felt on days I exercised"
· A weekly report

■ Plans, too
Write down what's coming and get a reminder.
See past entries and upcoming plans together on one calendar.
Export to your calendar app any time.

■ Look back
Meet what you wrote a month ago, or a year ago today.

■ Your backup, in your hands
Export everything to a single password-protected file.
Change phones and that one file brings it all across.
Nothing is uploaded to a cloud automatically.

■ About ads
A small banner appears only on browsing screens.
No ads while you are writing or editing an entry.
One purchase of Harukan Plus removes the ads and lifts the plan limit.
It is not a subscription — nothing is charged monthly.

The diary itself is completely free.
