The Keepsake Diary is a journal that writes back to you, every day. At the time you choose, a letter arrives in your diary with one question, written for you from what you have shared. Open the envelope, write your answer by hand or with the keyboard, and tap Finish. Tomorrow, a new letter. - One page a day. Add to it until midnight, then it is kept in your calendar as a gold envelope. - Write with Apple Pencil, your finger, or the keyboard. - Open any day you have written and read it again. - Your entries are encrypted on your device before they are saved. Only your devices can read them. - A home screen widget shows your streak and your week. The diary is written by AI. It is not a therapist or a real person. If something you write sounds like you might be in danger, the diary shows you real crisis resources. For adults 18 and over. Privacy policy: keepsakediary.com/privacy Terms: keepsakediary.com/terms
