Notes for your future self
Deja Note is a notes app where any note can be sealed until a date you choose. It stays hidden, even from you, until the day it comes back.
Free for Android. No ads.
The idea
Most notes are written for the next five minutes. Write for a reader a month or a year away and the writing changes. You leave out the noise. You explain what you’d normally assume. You make promises you might actually be held to.
Begin
Write freely, or start from a prompt: 668 of them across nine illustrated kinds of note, from Diary and Mindfulness to Work and Goal. Or tap Surprise me and let the die decide.
“What do you believe about yourself today that you suspect might change?”
Each prompt suggests when it ought to come back to you. With an account, Diary mode can offer one a day, at a time you choose.
Seal
Tomorrow morning. Next week. A year from tonight. Or any date you like, up to twenty years ahead. Your draft stays yours to fiddle with until the moment you seal it.
After that, it’s a promise. You can’t open it early, edit it, or move the date. That small act of letting go is the whole point: what you wrote stays exactly as you wrote it, waiting for whoever comes back to it.
Wait
A sealed note sits on your timeline as a gold seal and a quiet countdown. The prompt you answered is still there. The words aren’t, and not even search can find them.
There’s something pleasant about carrying a few of these around. A letter from last spring, a list from a hard week, a guess about how things would turn out. You know they’re there. You just don’t quite remember what they say.
Reveal
When the day comes, the ring closes, the seal breaks with a little gold light, and your words settle back into place. Ask to be notified and your phone will tell you a note is ready, without ever showing what it says.
What you find is rarely what you expected. A detail you’d forgotten. A worry that came to nothing. A corner dairy on an ordinary night. It’s like hearing from someone who knew you well, a while ago.
Every day
Plenty of notes are just notes, and Deja Note is a lovely everyday notebook too: rich text, photos, tags, pins and search, on a timeline that runs from what you’ve written to what’s still to come.
The calendar looks both ways at once: the days you wrote something, and the days something opens. Some days are simply quiet.
No. Until its date arrives, a sealed note can’t be read, edited, shared or rescheduled. You can still pin it, or delete it if you change your mind, and deleted notes stay in Trash for 30 days.
Tap Notify me after sealing and allow notifications, and you’ll get a reminder when the note opens. The reminder never includes what you wrote. The note itself unseals on time in the app either way, even without a connection, though the reminder can occasionally arrive a little late.
No. Choose to use it offline and your notes stay on your device. You can link an account later from Settings and bring those notes with you. An account, with Google or email, adds sync across your Android devices and Diary mode.
With an account, note text and photos are encrypted on your phone before they’re uploaded, and they’re stored encrypted in the cloud. This is not end-to-end encryption, and tags aren’t encrypted. Offline notes never leave your device. You can also require your fingerprint, face or device PIN to open the app, and export everything as Markdown whenever you like.
Nothing. Deja Note is free on Google Play for Android, with no ads and no in-app purchases.
Write one note today, seal it, and let it go. Some ordinary day, it will find you again.
