A diary whose entries never leave your phone.
Diarion is an app for daily entries: text, mood, habits, planner, notes and finances. No account, no sync, no analytics: everything you write sits in a database on the phone itself.
No account
Nothing to breach and no access to “recover”. You open the app and write.
No server
Entries are not sent anywhere, because there is nowhere to send them. Diarion has no servers of its own.
No analytics
No trackers, no ads, no advertising identifiers, no analytics SDKs.
What is inside
One app for several daily routines. You choose which of them to see.
A daily entry
Text, mood, sleep, how you feel, food, and a prompt for when you do not know where to start.
Habits
Check-offs, streaks and progress towards a weekly target. Streaks forgive a missed day.
Planner
The day's tasks, with reminders and repeats.
Notes
With formatting, tags, checklists and links between notes.
Finances
Spending by category, accounts, budgets, and a chart under the list.
Dashboard
A month of mood, habits and entries on one screen.
And more
Reading, good deeds, happy moments, a wishlist, a cycle calendar.
You choose
Anything you do not need switches off on first launch, or later in settings.
Privacy as plumbing, not as a promise
Every statement below has a counterpart in the app's code. The full list is in the privacy policy.
-
The database is encrypted on disk.The key is generated on your device and held in the system keystore. The developer does not have it and cannot obtain it.
-
A lock on the way in.PIN, Face ID or fingerprint. The PIN is stored as a hash, not as a number.
-
Backups are encrypted with a passphrase only you know.The app never stores it. Where the file goes is your choice, in the system share sheet.
-
Export to JSON, CSV and Markdown.Your entries are yours, and they leave in one tap, in open formats anything can read.
-
Delete everything with one button.In settings, or simply by deleting the app: its storage goes with it. No need to ask the developer, who has none of your data.
-
No account, server, analytics, ads or trackers.No cross-app tracking either. There is nothing to track.
Nothing goes over the network
The app itself makes no network requests: no telemetry, no update checks, no ads. The one connection is buying and checking the subscription, and iOS makes it through the App Store.
What it costs
Writing takes the Diarion Base subscription: $1.99 a month, $4.99 for three months or $11.99 a year, with the first 3 days free. Reading what you wrote, backing it up and exporting it always work, subscription or not. Terms.
