It's a great app. Simple and easy to navigate. I use it a lot to vent. And the clue for the password is supremely useful, since I forget things quite easily. One thing I've noticed though is that the default seems to be all lowercase letters. I don't mind it, maybe it can changed in the setting or something. Overall, great app, hope it stays forever.

I really love this app and have been using it every day to write my diary. But after reinstalling and restoring my data, I noticed that all my January 2025 entries are missing, even though I had backed them up to Google Drive. Those entries included some important photos and personal memories that mean a lot to me. Please look into this issue and help me recover them — I’d really appreciate your support and guidance

all my entries are gone since there was a new update. thanks🙂. All my lesson-plans, important notes, ideas, song lyrics, memories and other bunch of important but embarassing notes are gone. i even tried logging back in and restoring but nothing popped up no matter how many times I tried. at this point, I'm not even mad, but disappointed. imma keep it respectful tho, it's just one of those times, i guess.

Thank you for your feedback! Updating the app should not cause data loss. Did you uninstall the app or change devices? If you backed up before, logging in with the same account should restore your data. For further assistance, please contact us at diaryfeedback@gmail.com with more details, and we’ll do our best to help.
