A look inside
See it before you write in it
Calendar, moods, photos, themes and stats — this is what a year in My Diary looks like.
Features
Everything a diary should be
Simple enough to use every day, personal enough to feel like yours.
Mood tracker
Tap an emoji to record how the day felt, then watch your emotional patterns take shape over time.
Add your photos
Attach pictures to any entry and turn a few lines of text into a memory you can actually see.
Themes & stickers
Backgrounds, fonts, colours, emojis and stickers — change the look as often as your mood changes.
Year in Pixels
One coloured square for every day. A whole year of feeling, in a single glance.
Stats & streaks
See how often you write, which moods show up most, and keep a writing streak going.
Your privacy
What you write stays on your phone
A diary is only worth keeping if you can be honest in it. That is why My Diary has no accounts and no sync to us — your entries, photos and moods live on your device.
- No account needed. Nothing to sign up for, nothing to sign in to.
- Your entries are never sent to our servers. We cannot read them, because we never receive them.
- Backups belong to you. Back up to your own Google Drive or iCloud, in private space we have no access to.
- No data sold or shared with third parties.
