Five-Year Diary

The paper five-year diary, made for Android. Write one line today; next year, on the same date, last year's line is waiting underneath it — then two, then three. With a daily reminder you can answer from the notification, and a home-screen widget.

What it does on Android

  • 01

    Every year on one page

    Each date has one page, and each year adds a line to it, the newest at the top. Until there is a last year to read, the page shows nearby days instead — four weeks ago, a month ago, a hundred days ago.

  • 02

    Answered from the notification

    Once a day, at the time you choose, a reminder shows what you wrote on this date in earlier years, and takes today's line right there in the shade.

  • 03

    The widget and the year

    The home-screen widget shows this date in other years; a tap opens the day. The year view lays out twelve months, every day filled or empty — no streaks, no score, no badges.

  • 04

    Your words are a file

    Every diary exports as plain text or Markdown, free, to any folder or cloud drive you choose. An old diary kept as dated lines in a text file can be brought in.

  • 05

    One purchase, once

    Writing, the past years, the year view, the widget, the reminder, dark mode, the bin and plain export are free. One purchase, never a subscription, adds a question for every day of the year, a photograph with a line, more diaries, sealed copies, and three typefaces in three sizes.

  • 06

    Nothing to sign in to

    No account, no server of ours, no advertising and no analytics. The diary stays on your phone, in Android's own backup if you have it on, and in the files you export.

Network accessOnly Google Play's: the purchase, the update check and the rating card. The app's own code opens no connection, and the diary works offline.
BackupYour diaries, their lines and your settings are included in Android's own backup to your Google Account, if backup is on — the photographs are not. None of it reaches us.
NotificationsOne a day, the reminder, at the time you choose, and only if you turn it on.
PriceFree to download, with one purchase inside — bought once, never a subscription.
Privacy policyRead

One permission is asked for, and only when you turn on the reminder: notifications. Google Play runs the purchase, the update check and the rating card, and in the United States the app asks Google Play for an age range, reads it and drops it; section 8 of the privacy policy says what Google collects for each. The app itself collects nothing.

The sealed format

A sealed copy opens without the app

A sealed copy is your whole diary in one file, every photograph included, locked with a passphrase. Its format is published, with a short reader in Python and its test vectors, all CC0 — so a sealed copy can be opened on any computer, without this app and without us.
