TimePeace is not only for the days since you installed it. Add the moments from earlier in your life — where you lived, the jobs, the trips, the people, the turning points — and read your story end to end in one place. You can print a chapter of it, or simply keep it.
As far as you want. You add earlier-in-life moments with the year they happened, so a childhood house, a first job and last Tuesday all sit on the same thread — the recent ones logged as you go, the older ones written in when you think of them.
There is a life-story view that runs your whole record end to end, rather than the usual week or month. It reads like a book of your own days, because that is what it was built from.
Yes — export a chapter to keep or to print. It is your story; you should be able to hold it in your hand and hand it on.
No. Nothing here is published, shared or shown to anyone. It is written for you, and for whoever you choose to give it to yourself.
Most journals start the day you download them. TimePeace lets the years before it exist too — so what you keep is a life story, not a usage history.
