The diary stays on the phone.
DayDayLog has no account and no cloud copy. Nothing in the journal is sent to DayDayLog.
Write a day
Open a date on the calendar. Write a topic, or just the day. It saves on the device.
Choose a cover
A cover comes from a photo you pick. The app copies that picture, resizes it, and keeps it on the device. On Android this uses the system photo picker. The app does not ask for the camera or for the whole photo library.
Remove a day
Remove the cover from the day, and clear the writing. Uninstalling the app deletes the diary. There is no account to delete and no copy on a server.
Share
Sharing is optional. It opens the system share sheet for one picture. That does not upload the diary.
Questions about the app can be sent from the App Store or Google Play listing.
