We think you should know exactly what reaches us. TimePeace is built to need very little: most of your life stays on your device or scrambled to your key. Here is the honest list: what we can see, what we never can, and why the small amount we do see is there to help you, not us.
Three reasons only: to sign you in, to sync your diary across your devices, and, if you allow it, to learn what to improve. Never to profit from you. There is no ad business and no data sale here, so there is no reason to hoard your life.
Events, not content: that a screen was opened, a feature used. Who did it is a one-way code computed on our server, not your identity, and never what you wrote. It is off unless you turn it on, and you can turn it back off whenever you like.
Yes, any time: download everything, delete anything, and it is really gone, and withdraw any permission as easily as you gave it.
